1 距离保护(ZM1-5)1 情况 概述距离保护装置是在输电网和变电网中应用得最广泛的一种保护装置。在配电网中它也变得越来越重要。主要原因如下:*它在线路两端之间的通信通道中的独立性,是因为它是利用本地有效电流和电压信息动作的。*距离保护在电力网中形成了一个相互关联的有选择性的保护系统(非单元式的保护系统)。这意味着它也可以作为网络中其他主要元件的远后备保护。现代线路保护的基本要求,比如快速性,灵敏性和选择性,以及在可靠性和安全性方面的严格要求,变得越来越严格。另外,现代距离保护在网络中必须能够与阻抗继电器配合动作,这是一种由不同技术设计而成的继电器(静态或者是机电式继电器)。较早的阻抗继电器在多数情况下只用于电力线路的相间和三相故障的保护,一些其他保护用于接地故障中。由于这些原因现代距离保护的灵活性非常重要,当它用于一个复杂的网络结构时尤其合适。比如并列运行的多回线路和辐射网。距离保护的有选择性动作不是依靠线路两端间的通信设备。距离保护能在远方末端电流互感器处检测到故障。这个功能使它成为那些不能检测到超过反方向末端电流互感器范围以外故障的线路差动保护的一个理想补偿。距离保护范围在线路REX 5XX的保护、控制和终端监测方面的距离保护装置由3到5个独立的距离保护范围组成,每一个包括了3个接地故障的测量元件和3个相间故障的测量元件。对于各种不同电压等级在不同的电网中,不同的终端要适合不同的要求。由于这个原因,距离保护装置的一些特征参数各终端之间是不同的(要了解详细内容,请查阅线路保护终端的分类细节)。距离保护区域5不同于其他段在于它动作的快速性。它比其他距离保护段启动快,而且在不同的系统暂态过程中,由于这个原因误动的可能性就更高了,因此它只适用于以下情况:允许更高越限或者作为具有超过100ms延时的延时距离保护段。线路差动保护的补充在一些线路差动保护终端设备中(如REL 561)距离保护装置能够成为一个有选择性的保护。同时它是超出反方向末端电流互感器以外故障时的主保护,这个功能由带延时段实现(如II段),它覆盖了所有相邻母线,因此形成了母线的主保护或后备保护。所以超越段应处于持续动作状态。保护范围为部分线路的保护段(如I段)可以作为线路差动保护的后备。只要差动保护动作这个功能就不需要了。为了减小I段误动的风险,可以在差动保护拒动时将其投入,差动保护失灵的最大原因就是通信系统故障。由于这个原因用于距离保护的通信方案应该使用另一个通信途径而舍弃用于线路差动保护的那一个方案。简单参数的整定每一距离保护段基本上包含了作为相对地、相间测量的完全独立的整定参数。这是复杂网络结构中和那些被要求使新配置的距离保护装置适应目前其他类型继电器的网络的一个优势情况。一套简明的可选择参数适用于反映各种类型故障的相同最大保护范围是一个标准惯例的场合。参看整定参数和整定操作说明表格。基本特性作为合成到线路REX 5XX保护终端的距离保护装置是一个全方案的距离保护。这意味着在不同范围内对于各种类型故障它都有单独的测量元件。根据终端类型,它至少由5个独立的阻抗测量范围(详情参看通信规则详文)组成,每一个都是四边形特性,示例插图如图38。RL和XL代表线路电阻和电抗,RF代表保护范围的电阻最大值。A2 Line impedanceAbout this chapterThis chapter describes the line impedance functions in the 1 Distance protection (ZM1-5)1 ApplicationGeneralThe distance protection function is the most widely spread protection function in transmission and subtransmission It is also becoming increasingly important indistribution The main reasons for this are:• Its independence on communication links between the line ends, because for its operation,it uses information about the locally available currents and • The distance protection forms a relatively selective protection system (non-unit protectionsystem) in the power This means that it can also operate as a remoteback-up protection for other primary elements in the The basic requirements for modern line protection, such as speed, sensitivity and selectivity, with their strict requirements for dependability and security (availability), aregetting more In addition, modern distance protections must be able to operate in networks with existing distance relays, which are mostly designed in a different technology (static or even electromechanical relays)Older distance relays protect in many cases power lines only at phase-to-phase and three-phase Some other protection is used for phase-to-earth The flexibility of modern distance protection is for this reason very This especially applies when it is used in a complex network configuration, for example, on parallel operating multicircuit lines and on multiterminal The selective operation of the distance protection does not depend on communication facilities between two line At the same time, the distance protection can detect faults beyond the current transformers at the remote This functionality makes it an ideal complement to the line differential protection function that cannot detect faults beyond the current transformer at the opposite Distance protection zonesThe distance protection function in REx 5xx line protection, control, and monitoring terminals consists of three to five independent distance protection zones, each of them comprising three measuring elements for phase-to-earth (Ph-E) faults and/or three measuring elements for phase-to-phase (Ph-PH) Different terminals suit different requirements in different networks on various voltage For this reason, some characteristic parameters of the distance protection function differ from terminal to For detailed information, please refer to ordering particulars for each line protection terminal REx 5xx Distance protection zone five differs from other zones with respect to its speed of It starts faster than other distance protection zones and might have for this reason higher overreaching for different system It is for this reason suggested to use it only for the applications, which permit higher overreaching, ( switch-onto-fault function) or as a time delayed distance protection zone with time delay longer than 100 Complement to the line differential protectionThe distance protection function can become optional protection in some line differential protection terminals (REL 561, for example) At the same time it represents the primary protection for faults beyond the current transformers at the opposite This functionality is achieved by the time delayed overreaching zone (generally zone 2), which covers at least the adjacent busbar and thus forms a primary or back-up protectionfor the So the overreaching zone should be continuously in An underreaching zone (generally zone 1) can form a back-up to the line differential There is no need for this function as long as the differential protection is in To minimize the risk of unwanted operation from zone 1, this function can be activated only when the differential function is out of The most likelycause to lose the differential protection is a failure within the communication The communication scheme used with the distance protection should for this reason use another communication channel than the one used by the line differential Set of simplified setting parametersEach distance protection zone comprises basically completely independent setting parameters for phase-to-earth, and for phase-to-phase This is an application advantage in complex network configurations and in networks, where it is required to adjust the newly applied distance protection functions to the existing other types of relays (overcurrent earth fault, for example)A set of simplified optional parameters is available optionally for applications, where equal zone reaches for all kinds of faults are a standard See the table of setting parameters and the setting Line impedanceBasic characteristicsThe distance protection function, as built into the REx 5xx line protection terminals, is a full-scheme distance This means that it has individual measuring elements for different types of faults within different Depending on the type of terminal, it consists of up to five (for details see the corresponding ordering details) independent, impedance-measuring zones, each has a quadrilateral characteristic, as symbolically illustrated in figure RL and XL represent line resistance and reactance and RF represents the resistive reach of a protective

电气工程(Electrical Engineering简称EE)是现代科技领域中的核心学科之一,更是当今高新技术 电气工程领域中不可或缺的关键学科。例如正是电子技术的巨大进步才推动了以计算机网络为基础的信息时代的到来,并将改变人类的生活工作模式。电气工程的发展前景同样很有潜力,使得当今的学生就业比率一直传统的电气工程定义为用于创造产生电气与电子系统的有关学科的总和。电气系统所在领域是一个充满希望且具有挑战性的领域。 说电气系统属于工程专业,是因为工程学的挑战在于要设计所有电路系统,并把它们聚类成一个整体。Cyber-physics system是最有代表性的前沿电路系统,包括物联网、普适计算、传感器。 电气工程[2]是现代科技领域中的核心学科之一,更是当今高新技术领域中不可或缺的关键学科。从某种意义上讲,电气工程的发达程度代表着国家的科技进步水平。正因为此,电气工程的教育和科研一直在发达国家大学中占据十分重要的地位。美国大学电气工程学科在机构名称上有的学校称电气工程系,有的称为电气工程与信息科学系,有的称为电气工程与计算机科学系等等。该学科(系)在科研、教学及学术组织形式上与国内电气工程学科有较大不同。了解国外学科状态及教学、科研方向,对调整我们的学科方向、提高教学、科研水平具有十分重要的作用。   传统的电气工程定义为用于创造产生电气与电子系统的有关学科的总和。此定义本已经十分宽泛,但随着科学技术的飞速发展,21世纪的电气工程概念已经远远超出上述定义的范畴,斯坦福大学教授指出:今天的电气工程涵盖了几乎所有与电子、光子有关的工程行为。本领域知识宽度的巨大增长,要求我们重新检查甚至重新构造电气工程的学科方向、课程设置及其内容,以便使电气工程学科能有效地回应学生的需求、社会的需求、科技的进步和动态的科研环境。

摘要:本文主要介绍了近年来电气自动化技术的发展,以及应用的概况。电气自动化技术尽管已经广泛应用与我国国民生产的各个部门和领域,但它仍需要不断革新,不断发展。关键词:电气自动化;发展;应用一、发展概况伴随着我国的电力电子技术、微电子技术的飞速发展,电气自动化的概念已经走出了工厂,并在交通、农业、建筑、办公场所等方面得到了广泛的应用,电气自动化技术作为从电气工程技术发展出来的并与电子与信息技术紧密结合起来的一门电气工程应用技术学科,历经了近一个世纪的发展,电气自动化技术已走过了从无到有、从发展到成熟的过程。而我国电气自动化的研究工作可以追溯到上世纪的五十年代,可以说研究的时间不短,但是它依旧焕发着生气与活力。下文就来简述一下我国电气自动化的发展历程:(一)全空型的电力电子开关。于上世纪五十年代晶闸管出现了,它标志着运动控制的新纪元。尽管它是第一代电子电力器件,但仍被沿用至今。随后交流变频技术出现后相继有出现了全控制式器件如GTR等。这是电力电子器件的第二代;接下来是IGBT和MGT这一类复合型电力电子器件可以称为第三代器件。最后是功率集成电路,PIC即第四代电力电子器件。(二)由低频向高频方向发展的电路。不断更新的电力电子器件势必要引发变换器电路的换代。当应用于普通晶闸管时,直流传动的变换器主要是整流相互控制,交流变频传动则是交—直—交变频器。当电力电子器件转换到第二代的时候,PWM变换器采用的相应也要多些。因为采用了PWM变换器之后不仅提高了功效,并且能够减少高次谐波对电网的影响,合理解决了电动机在低频区的转矩脉动问题。随着应用的深入,PWM也存在着诸多缺陷,因此也就有了谐振式直流逆变器电路的发展。(三)交流调速控制理论。交流电机磁场定向远离市由德国学者F·Blaschke所提出来的,这一理论的提出为交流传动高性能控制奠定了深刻的理论基础。但他提出的这个思想远不能够达到理论的操控效果。于是事隔14年后于1985年德国鲁德大学的Depenbrock教授又提出了直接转矩控制的思想,紧接着有将它推放到了弱磁调速的范围内。可以说他的这一控制思想新颖,控制结构简单明了,信号处理的物理概念明确,是一种高静动态性能的新型交流调速方法。(四)通用变频器的投入使用。通用变频器:系列化、批量化、占市场量最大的中小功率变频器。先后变频器经历了第一代:普通功能型U/F控制型;第二代:高功能型U/F型;第三代:高动态性能适量控制型。(五)单片机的发展。占主导地位的MCS-51的8位机虽占主导地位,但是它的功能还比较简单,指令集短小,因此就有了适合大批量生产的PIC系列单片机的推广使用,它不仅具有很高的可靠性,而且保密性高。二、电气自动化的应用(一)建筑中的应用。智能化建筑势必要引入电气自动化的成分,随着我国国民经济的飞速发展以及数字电子化科技发展,无疑,高档智能化建筑已经成为了当今建筑界的主流方向。为了达到设备的合理利用,三明的人力的节省就有了建筑设备的自动化控制系统。例如:在建筑物供配电设计中,接地系统没计占有重要的地位,因为它关系到供电系统的可靠性,安全性。IN—S是一个三相四线J/NPE线的接地系统。通常建筑物内设有独立变配电所时进线采用该系统。TN—s系统的特点是,中性线N与保护接地线PE除在变压器中性点共同接地外,两线不再有任何的电气连接。中性线N是带电的,而PE线不带电。该接地系统完全具备安全和可靠的基准电位。只要像TN—C—S接地系统,采取同样的技术措施,TN—S系统可以用作智能建筑物的接地系统。智能建筑应没置电子设备的直流接地,交流工作接地,安全保护接地及普通建筑也应具备的防雷保护接地。智能化建筑内有大量的电子设备与布线系统,如通信自动化系统,火灾报警及消防联动控制系统,楼宇自动化系统,保安监控系统,办公自动化系统,闭路电视系统等,以及他们相应的布线系统。这些电子设备及布线系统一般均属于耐压等级低,防干扰要求高,最怕受到雷击的部分。建立严密,完整的防雷结构。智能建筑多属于一级负荷,应按一级防雷建筑物的保护措施设计,组成具有多层屏蔽的笼形防雷体系。(二)应用于净化空调设备。净化空调系统控制自动监控装置,可设计成单个系统的测量、控制系统,也可设计成数字计算机控制管理系统。对温度的控制。净化空凋系统采用DDC控制。装设在回风管(回风温度近似于洁净室温度)的温度传感器所检测的温度送往DX一9100,与设定点相比较,用比例加积分加微分运算进行控制,输出相应电压信号,控制加热电动调节阀或冷水电动调节阀的动作,控制回风温度保持在18"12—26‘℃之间,使洁净室温度符合GMP要求。对湿度的控制。装设在同风管(回风湿度近似丁洁净室湿度)内的湿度传感器所检测的湿度,送往控制器与设定湿度相比较,用比例加积分运算控制,输出电JK信号,控制蒸汽电动调节阀的动作,控制回风湿度保持在45%65%,使洁净室湿度以满足GMP要求。电气自动化技术尽管已经广泛应用与我国国民生产的各个部门和领域,但它仍需要不断革新,不断发展。Abstract: This paper introduces the recent development of electrical automation technology, and application Although electrical automation technology has been widely used in various sectors of our national production and areas, but it still requires constant innovation, continuous Key words: electrical automation; development; applications I Development Overview Along with China's power electronics technology, the rapid development of microelectronics technology, electrical automation concept has been out of the factory, and in transportation, agriculture, construction, office space and other aspects of a wide range of applications, electrical automation technology as the electrical engineering from the developed and closely with the electronics and information technology to combine an electrical engineering technology disciplines, after nearly a century, electrical automation technology has come a scratch, from development to The electrical automation of research can be traced back to the fifties of the last century can be said of the time a lot, but it still glow with vitality and To describe briefly below to the course of development of electrical automation: (A) all air-based power electronic Thyristor in the fifties of last century there, it marks a new era of motion Although it is the first generation of electronic power devices, but was still in AC variable frequency technology appears then there have appeared a full-control devices, such as GTR and so This is the second generation of power electronic devices; followed this type of IGBT and MGT hybrid power electronic devices can be called third-generation Finally, power integrated circuits, PIC is the fourth generation of power electronic (B) the direction of low frequency to high frequency Constantly updated to power electronic devices will inevitably lead to the replacement converter When applied to a thyristor, the DC transmission between the converter is mainly controlled rectifier, AC variable frequency drive is AC - DC - AC When the power switch to the second generation of electronic devices, when, PWM converters have adopted more After using the PWM converter because not only improve the efficiency and to reduce the high harmonics of the grid and reasonable solution to the motor torque ripple in the low frequency With the application of in-depth, PWM also has many defects, so DC will have a resonant inverter circuit (C) AC speed control AC motor field oriented away from the city by the German scholar F · Blaschke made out, this theory put forward for the AC drive for high performance has laid a profound theoretical However, he proposed this idea is far from control theory to achieve So 14 years later in Germany in 1985 after the University of Depenbrock Professor Rood also proposed the idea of ​​direct torque control, followed by a push it into the field weakening speed It can be said that control thought his novel control structure is simple, clear physical concept of signal processing, static and dynamic properties of a new type of high speed communication (D) Common drive in Universal Converter: serialization and batch, the largest market share of small and medium-power The first generation drive has gone through: common functional U / F control type; second generation: high-functional U / F type; the third generation: amount of controlled high dynamic (E) the development of SCM Dominant MCS-51 8-bit machines, although the dominant, but its function is still relatively simple, short set of instructions, hence suitable for mass production of the PIC MCU promote the use of, it not only has high reliability and high Second, the Electric Automation (A) B Intelligent building automation is bound to bring in electrical components, along with the rapid development of China's national economy and the development of digital electronic technology, no doubt, high-end intelligent building has become the mainstream of today's construction In order to achieve rational use of equipment, manpower saving in Sanming have a building automation control system For example: In the design of buildings for power distribution, grounding system plays an important role not count, because it relates to the power supply system reliability, IN-S is a three-phase four-wire J / NPE line grounding Usually buildings are equipped with separate substation into the line when using the TN-s system is characterized by the neutral and protective earth line PE N addition to the common grounding transformer neutral point, the two lines no longer have any electrical Neutral line N is live, and PE line is not The grounding system is fully equipped with safe and reliable reference As long as the TN-C-S earthing system, adopt the same technical measures, TN-S system can be used as a smart building grounding Intelligent building should not set the DC grounding electronic equipment, exchange of ground, ground and general building security should have the lightning protection Intelligent building, a large number of electronic devices and wiring systems, such as communications automation systems, fire alarm and fire control systems, building automation systems, security monitoring systems, office automation systems, CCTV systems, as well as their corresponding wiring The electronic equipment and cabling system voltage levels are generally lower for high anti-interference, fear by the lightning The establishment of strict and complete the mine Intelligent Building is a multi-load, should be a lightning protection design of buildings to form a multi-layer shielding cage lightning protection (B) applies to clean air conditioning Air conditioning system controls automatic monitoring device can be designed into a single system of measurement, control systems, can also be designed into digital computer-controlled management Temperature Gas purification system using DDC control Installed in return air duct (return air temperature is similar to the clean room temperature) The temperature detected by temperature sensor sent a DX 9100, compared with the set point with proportional plus integral plus derivative control operation, the output corresponding voltage signal, electric control valve controlling the heating or cold water electric control valve movement and control the return air temperature maintained at 18 "12-26 '℃ between the clean room temperature meet GMP of humidity installed in the same duct (return Approximate Jie Ding cleanroom air humidity humidity) sensors detect the humidity within the humidity, sent to the controller and set the humidity compared to the control with proportional plus integral operation, the output JK signals to control the action of steam electric control valve to control back wind and humidity kept at 45% 65%, so the clean room to meet the GMP requirements and Although electrical automation technology has been widely used in various sectors of our national production and areas, but it still requires constant innovation, continuous

摘要:本文主要介绍了近年来电气自动化技术的发展,以及应用的概况。电气自动化技术尽管已经广泛应用与我国国民生产的各个部门和领域,但它仍需要不断革新,不断发展。关键词:电气自动化;发展;应用一、发展概况伴随着我国的电力电子技术、微电子技术的飞速发展,电气自动化的概念已经走出了工厂,并在交通、农业、建筑、办公场所等方面得到了广泛的应用,电气自动化技术作为从电气工程技术发展出来的并与电子与信息技术紧密结合起来的一门电气工程应用技术学科,历经了近一个世纪的发展,电气自动化技术已走过了从无到有、从发展到成熟的过程。而我国电气自动化的研究工作可以追溯到上世纪的五十年代,可以说研究的时间不短,但是它依旧焕发着生气与活力。下文就来简述一下我国电气自动化的发展历程:(一)全空型的电力电子开关。于上世纪五十年代晶闸管出现了,它标志着运动控制的新纪元。尽管它是第一代电子电力器件,但仍被沿用至今。随后交流变频技术出现后相继有出现了全控制式器件如GTR等。这是电力电子器件的第二代;接下来是IGBT和MGT这一类复合型电力电子器件可以称为第三代器件。最后是功率集成电路,PIC即第四代电力电子器件。(二)由低频向高频方向发展的电路。不断更新的电力电子器件势必要引发变换器电路的换代。当应用于普通晶闸管时,直流传动的变换器主要是整流相互控制,交流变频传动则是交—直—交变频器。当电力电子器件转换到第二代的时候,PWM变换器采用的相应也要多些。因为采用了PWM变换器之后不仅提高了功效,并且能够减少高次谐波对电网的影响,合理解决了电动机在低频区的转矩脉动问题。随着应用的深入,PWM也存在着诸多缺陷,因此也就有了谐振式直流逆变器电路的发展。(三)交流调速控制理论。交流电机磁场定向远离市由德国学者F·Blaschke所提出来的,这一理论的提出为交流传动高性能控制奠定了深刻的理论基础。但他提出的这个思想远不能够达到理论的操控效果。于是事隔14年后于1985年德国鲁德大学的Depenbrock教授又提出了直接转矩控制的思想,紧接着有将它推放到了弱磁调速的范围内。可以说他的这一控制思想新颖,控制结构简单明了,信号处理的物理概念明确,是一种高静动态性能的新型交流调速方法。(四)通用变频器的投入使用。通用变频器:系列化、批量化、占市场量最大的中小功率变频器。先后变频器经历了第一代:普通功能型U/F控制型;第二代:高功能型U/F型;第三代:高动态性能适量控制型。(五)单片机的发展。占主导地位的MCS-51的8位机虽占主导地位,但是它的功能还比较简单,指令集短小,因此就有了适合大批量生产的PIC系列单片机的推广使用,它不仅具有很高的可靠性,而且保密性高。二、电气自动化的应用(一)建筑中的应用。智能化建筑势必要引入电气自动化的成分,随着我国国民经济的飞速发展以及数字电子化科技发展,无疑,高档智能化建筑已经成为了当今建筑界的主流方向。为了达到设备的合理利用,三明的人力的节省就有了建筑设备的自动化控制系统。例如:在建筑物供配电设计中,接地系统没计占有重要的地位,因为它关系到供电系统的可靠性,安全性。IN—S是一个三相四线J/NPE线的接地系统。通常建筑物内设有独立变配电所时进线采用该系统。TN—s系统的特点是,中性线N与保护接地线PE除在变压器中性点共同接地外,两线不再有任何的电气连接。中性线N是带电的,而PE线不带电。该接地系统完全具备安全和可靠的基准电位。只要像TN—C—S接地系统,采取同样的技术措施,TN—S系统可以用作智能建筑物的接地系统。智能建筑应没置电子设备的直流接地,交流工作接地,安全保护接地及普通建筑也应具备的防雷保护接地。智能化建筑内有大量的电子设备与布线系统,如通信自动化系统,火灾报警及消防联动控制系统,楼宇自动化系统,保安监控系统,办公自动化系统,闭路电视系统等,以及他们相应的布线系统。这些电子设备及布线系统一般均属于耐压等级低,防干扰要求高,最怕受到雷击的部分。建立严密,完整的防雷结构。智能建筑多属于一级负荷,应按一级防雷建筑物的保护措施设计,组成具有多层屏蔽的笼形防雷体系。(二)应用于净化空调设备。净化空调系统控制自动监控装置,可设计成单个系统的测量、控制系统,也可设计成数字计算机控制管理系统。对温度的控制。净化空凋系统采用DDC控制。装设在回风管(回风温度近似于洁净室温度)的温度传感器所检测的温度送往DX一9100,与设定点相比较,用比例加积分加微分运算进行控制,输出相应电压信号,控制加热电动调节阀或冷水电动调节阀的动作,控制回风温度保持在18"12—26‘℃之间,使洁净室温度符合GMP要求。对湿度的控制。装设在同风管(回风湿度近似丁洁净室湿度)内的湿度传感器所检测的湿度,送往控制器与设定湿度相比较,用比例加积分运算控制,输出电JK信号,控制蒸汽电动调节阀的动作,控制回风湿度保持在45%65%,使洁净室湿度以满足GMP要求。电气自动化技术尽管已经广泛应用与我国国民生产的各个部门和领域,但它仍需要不断革新,不断发展。Abstract: This paper introduces the recent development of electrical automation technology, and application Although electrical automation technology has been widely used in various sectors of our national production and areas, but it still requires constant innovation, continuous Key words: electrical automation; development; applications I Development Overview Along with China's power electronics technology, the rapid development of microelectronics technology, electrical automation concept has been out of the factory, and in transportation, agriculture, construction, office space and other aspects of a wide range of applications, electrical automation technology as the electrical engineering from the developed and closely with the electronics and information technology to combine an electrical engineering technology disciplines, after nearly a century, electrical automation technology has come a scratch, from development to The electrical automation of research can be traced back to the fifties of the last century can be said of the time a lot, but it still glow with vitality and To describe briefly below to the course of development of electrical automation: (A) all air-based power electronic Thyristor in the fifties of last century there, it marks a new era of motion Although it is the first generation of electronic power devices, but was still in AC variable frequency technology appears then there have appeared a full-control devices, such as GTR and so This is the second generation of power electronic devices; followed this type of IGBT and MGT hybrid power electronic devices can be called third-generation Finally, power integrated circuits, PIC is the fourth generation of power electronic (B) the direction of low frequency to high frequency Constantly updated to power electronic devices will inevitably lead to the replacement converter When applied to a thyristor, the DC transmission between the converter is mainly controlled rectifier, AC variable frequency drive is AC - DC - AC When the power switch to the second generation of electronic devices, when, PWM converters have adopted more After using the PWM converter because not only improve the efficiency and to reduce the high harmonics of the grid and reasonable solution to the motor torque ripple in the low frequency With the application of in-depth, PWM also has many defects, so DC will have a resonant inverter circuit (C) AC speed control AC motor field oriented away from the city by the German scholar F · Blaschke made out, this theory put forward for the AC drive for high performance has laid a profound theoretical However, he proposed this idea is far from control theory to achieve So 14 years later in Germany in 1985 after the University of Depenbrock Professor Rood also proposed the idea of ​​direct torque control, followed by a push it into the field weakening speed It can be said that control thought his novel control structure is simple, clear physical concept of signal processing, static and dynamic properties of a new type of high speed communication (D) Common drive in Universal Converter: serialization and batch, the largest market share of small and medium-power The first generation drive has gone through: common functional U / F control type; second generation: high-functional U / F type; the third generation: amount of controlled high dynamic (E) the development of SCM Dominant MCS-51 8-bit machines, although the dominant, but its function is still relatively simple, short set of instructions, hence suitable for mass production of the PIC MCU promote the use of, it not only has high reliability and high Second, the Electric Automation (A) B Intelligent building automation is bound to bring in electrical components, along with the rapid development of China's national economy and the development of digital electronic technology, no doubt, high-end intelligent building has become the mainstream of today's construction In order to achieve rational use of equipment, manpower saving in Sanming have a building automation control system For example: In the design of buildings for power distribution, grounding system plays an important role not count, because it relates to the power supply system reliability, IN-S is a three-phase four-wire J / NPE line grounding Usually buildings are equipped with separate substation into the line when using the TN-s system is characterized by the neutral and protective earth line PE N addition to the common grounding transformer neutral point, the two lines no longer have any electrical Neutral line N is live, and PE line is not The grounding system is fully equipped with safe and reliable reference As long as the TN-C-S earthing system, adopt the same technical measures, TN-S system can be used as a smart building grounding Intelligent building should not set the DC grounding electronic equipment, exchange of ground, ground and general building security should have the lightning protection Intelligent building, a large number of electronic devices and wiring systems, such as communications automation systems, fire alarm and fire control systems, building automation systems, security monitoring systems, office automation systems, CCTV systems, as well as their corresponding wiring The electronic equipment and cabling system voltage levels are generally lower for high anti-interference, fear by the lightning The establishment of strict and complete the mine Intelligent Building is a multi-load, should be a lightning protection design of buildings to form a multi-layer shielding cage lightning protection (B) applies to clean air conditioning Air conditioning system controls automatic monitoring device can be designed into a single system of measurement, control systems, can also be designed into digital computer-controlled management Temperature Gas purification system using DDC control Installed in return air duct (return air temperature is similar to the clean room temperature) The temperature detected by temperature sensor sent a DX 9100, compared with the set point with proportional plus integral plus derivative control operation, the output corresponding voltage signal, electric control valve controlling the heating or cold water electric control valve movement and control the return air temperature maintained at 18 "12-26 '℃ between the clean room temperature meet GMP of humidity installed in the same duct (return Approximate Jie Ding cleanroom air humidity humidity) sensors detect the humidity within the humidity, sent to the controller and set the humidity compared to the control with proportional plus integral operation, the output JK signals to control the action of steam electric control valve to control back wind and humidity kept at 45% 65%, so the clean room to meet the GMP requirements and Although electrical automation technology has been widely used in various sectors of our national production and areas, but it still requires constant innovation, continuous
