中文2012字110Kv power supply system relay protection function brief analysis Not only the 110Kv power supply system relay protection function brief analysis electrical power system security and the reliability relate electrical power system itself the movement, similarly relates in the power transmission scope the factories and mines, the enterprise, whether the inhabitant uses electricity normally.Because simultaneously the electrical power system has the strong connectivity, electrical power system interior any barrier all possibly affects the overall system normal operation, thus we must complete the power supply system practically the relay protection question.First, the 11OKV power supply systemGenerally speaking electrical power system including the electricity generation, changes the electricity, the electric transmission, the power distribution and uses electricity and so on five links, between five links restricted mutually, cooperates mutually has facilitated the electrical power system stability together.But in fact, because these five links not always in the identical place, the identical time complete, the electric transmission must surmount the vast area, simultaneously the electrical power system must not carry on the connection with the equipment, thus strengthened its movement environment complexity, causes electrical power system the zero failure rate to guarantee with difficulty.The 110Kv power supply system is in the entire electrical power system important constituent, it whether safe, stable, reliable movement, not only relates the system own movement quality, whether moreover relates in its power transmission scope general user normal prompt using electricity, it the economical normal development and the society is stably taking on the important energy safeguard duty to the power transmission scope in.Therefore the 110KV power supply system design and the movement management must observe national comprehensively the related standard and the standard, as well as correlation area specifically standard standard.In the 110Kv power supply system is containing a subsystems and two subsystems.Two subsystems were opposite in a subsystems are complex, violate the subsystems to include the relay protection installment, the automatic device and the secondary circuit.The relay protection installment is uses for in the power supply system to a subsystems to carry on the surveillance,the survey, the control and the protection, is composed set of special automatic devices by the relay.The reasonable relay protection installment correct establishment to guarantees the 110Kv power supply system the normal operation to have the positive function.Second, the relay protection digs reads and the related principleElectrical power system rapid development to the relay protection to propose unceasingly the new request, the electronic technology, the computer technology and the communication rapid development unceasingly has poured into the new vigor for the relay protection technology development.The relay protection is refers when in the electrical power system electric power part (for example generator, line and so on) or electrical power system itself has occurred the breakdown endangers the electrical power system safe operation, can to the attendant promptly send out the warning signal, or directly to the circuit breaker which controls sends out the trip order to terminate one kind of automated protection which these events develop, the relay protection equipment can monitor the electrical equipment the normal work situation, and sends out the prompt signal differently according to the normal work situation and the equipment movement maintenance condition, in order to the attendant carries on prompt processing, either carries on the adjustment automatically by the protective device, either continues these to move possibly can cause the accident electrical equipment to excise.Response normal work situation relay protection equipment common belt certain time-lag action.The relay protection principle of work mainly has used in the electrical power system the part has when the short circuit or the unusual situation the electrical quantity (electric current, voltage, power, frequency and so on) change as well as in transformer fuel tank when breakdown occurs the massive gas and the oil stream speed increase or the flowing tubing head pressure intensity increase the higher condition.The electrical power system request provides the safekeeping of security for it to continue the electricity installment to have following performance:(1) reliability. The reliability is refers to the protection to be supposed to move time the body should act reliably.Should not when the movement should reliable not act.The reliability is to the relay protection installment performance most basic request.(2) selectivity. The selectivity is refers first by the breakdown equipment logical 'OR' circuit itself protection excision breakdown, when the breakdown equipment logical 'OR' circuit itself protection or the circuit breaker resist moves, only then allows by the neighboring equipment to protect, the line protection or the circuit breaker malfunction protection excision breakdown.In order to guarantee has in the coordinate request protection and the identical protection has the coordinate request two parts (for example start and trip part or block system and movement part) the selectivity to the neighboring equipment and the line, its sensitivity coefficient and the operating time, should coordinate mutually in the ordinary circumstances.(3) sensitivity. The sensitivity is refers when the equipment logical 'OR' circuit occurs by the extent of protection in the metallicity short circuit, the protective device should have the essential sensitivity coefficient, each kind of protection smallest sensitivity coefficient has the specific stipulation in the regulations.Selectivity and sensitive request, through relay protection installation realization.(4) speed. The speed is refers to the protective device to be supposed to excise the short circuit breakdown as soon as possible, its date enhances the system stability, reduces the breakdown equipment and the line damage degree, reduces the breakdown to affect the scope, enhances automatic switches on again with the emergency power supply or the emergency apparatus automatic investment effect and so on.Third, relay protection in 11OKV power supply system Chen Ai function1. The guarantee continues the electricity system the reliability is plays the relay protection installment role the premise. Continues the electricity system the reliability is plays the relay protection installment role the premise.Generally speaking the relay protection reliability mainly by the disposition reasonable, the quality and the technical performance fine relay protection installment as well as the normal movement maintenance and the management guaranteed.2. Relay protection in electrical power system safe operation function. The relay protection mainly has following two points in the electrical power system safe operation function:(1) safeguard electrical power system security.When is protected when the electricalpower system part breaks down, should rapidly accurately for be separated from the breakdown part recent circuit breaker by this part relay protection equipment to send out the trip order, causes the breakdown part to interrupt promptly from the electrical power system, by maximum limit reduces to the electrical power system part itself damage, reduces to the electrical power system safe power supply influence, and satisfies the electrical power system certain specific requests (for example maintenance electrical power system transition condition stable and so on).（2）pair of electrical power system normal work carries on the prompt.Responded the electrical equipment the normal work situation, (whether there is and different e.g. frequent attendant) does send out the signal according to the normal work situation and the equipment movement maintenance condition, in order to the attendant carries on processing, either carries on the adjustment automatically by the equipment, either continues these to move can cause the accident electrical equipment to excise.Response normal work situation relay protection installment permission belt certain time-lag action.(3) pair of electrical power system movement carries on the monitoring.The relay protection is not merely an accident processing and the response installment, simultaneously also is monitors the electrical power system normal operation the installment.The relay protection is the electrical power system safe normal operation important safeguard, at present oneself after obtained the widespread application, along with the science and technology unceasing progress, the relay protection technology presents day by day to the microcomputer, the network, the intellectualization, protects, the control, the survey and the data communication integration development tendency.110KV供电系统继电保护作用浅析电力系统的安全性和可靠性不仅关系到电力系统本身的运行，同样关系到送电范围内的厂矿、企业、居民能否正常用电。

电力系统继电保护外文及翻译Power System ProtectionsThe steady-state operation of a power system is frequently disturbed by various faults on electrical equipment. To maintain the proper operation of the power system, an effective, efficient and reliable protection scheme is required. Power system components are designed to operate under normal operating conditions.However, due to any reason, say a fault, there is an abnormality, it is necessary that there should be a device which senses these abnormal conditions and if so, the element or component where such an abnormality has taken place is removed, i.e. deleted from the rest of the system as soon as possible. This is necessary because the power system component can never be designed to withstand the worst possible conditions due to the fact that this will make the whole system highly uneconomical. And therefore, if such an abnormality takes place in any element or component of the power system network, it is desirable that the affected element/component is removed from the rest of the system reliably and quickly in order to restore power in the remaining system under the normal condition as soon as possible.The protection scheme includes both the protective relays and switching circuits, i.e. circuit breakers. The protective relay which functions as a brain is a very important component. The protective relay is a sensing device, which senses the fault, determines its location and then sends command to the proper circuit breaker by closing its trip coil. The circuit breaker after getting command from the protective relay disconnects only the faulted element. this is why the protective relay must be reliable, maintainable and fast in operation.In early days, there used to be electromechanical relay of induction disk-type.However, very soon the disk was replaced by inverted cup, i.e.hollow cylinder and the new relay obtained was known as an induction cup or induction cylinder relay. This relay, which is still in use, possesses several important features such as higher speed; higher torque for a given power input an more uniform torque.However, with the advent of electronic tubes, electronic relays having distinct features were developed during 1940s. With the discovery of solid state components during 1950s, static relays with numerous advantages were developed. The use of digital computers for protective relaying purposes has been engaging the attention of research and practicing engineers since layer 1960s and 1980s. Now, the microprocessor/mini computer-based relaying scheme, because of its numerous advantages such as self –checking feature and flexibility, has been widely used in power system all over the world.The overall system protection is divided into following sections: (i)Generator protection,(ii)Transformer protection,(iii)Bus protection,(iv)Feederprotection,(v)Transmission line protection.Basic Requirements to Protective RelaysAny protection scheme, which i.e. required to safeguard the power system components against abnormal conditions such as faults, consists basically of two elements(i)Protective relay and (ii) Circuit breaker .The protective relay which is primarily the brain behind the whole scheme plays a very important role. Therefore proper care should be taken in selecting an appropriate protective relay which is reliable, efficient and fast in operation. The protective relay must satisfy the following requirements:⑴ since faults on a well designed and healthy system are normally rare, therelays are called upon to operate only occasionally. This means that therelaying scheme is normally idle and must operate whenever fault occurs. Inother words, it must be reliable.⑵ Since the reliability partly depends upon the maintenance, the relay mustbe easily maintainable.⑶ The palpation of the relay can be in two ways. One is the failure to operatein case a fault occurs an second is the relay operation when there is no fault.As a matter of fact, relay must operate if there is a fault and must notoperate if there is no fault.⑷Relaying scheme must be sensitive enough to distinguish between normaland the faulty system.Protective RelaysThe function of the protective relay is to sense the fault and energize the tripcoil of the circuit breaker. The following types of the protective relays are usedfor the apparatus such as synchronous machines, bus bar, transformer and theother apparatus and transmission line protection.(1) Over current relays,(2) Under voltage relays,(3) Under frequency relays,(4) Directional relays,(5) Thermal relays,(6) Phase sequence relays such as(i)negative sequence relays and, (ii)zerosequence relays,(7) Differential relays and percentage differential relays,(8) Distance relays such as (I)plane impedance relays,(ii)angle impedance relay,i.e. Ohm or reactance relays,(iii)angle admittance relays,i.e. Mho relaysand ,(iv)offset and restricted relays,(9)Pilot relays such as (i) wire pilot relays,(ii)carrier channel pilotrelays,(iii)microwave pilot relays. There are different types of the relayingscheme based on construction. They are:(i)electromechanicaltype,(ii)thermal relays,(iii) transduction relays,(iv)rectifier bridgerelay,(v)electronic relays,(vi)digital relaying schemes.电力系统继电保护电力系统的稳态运行经常会因各种电力设备配故障原因而被扰乱。

回顾我国电力系统继保护技术发展的过程中，概述了微机继电保护技术的成就，提出了未来继电保护技术发展趋势将是：计算机化，电网络化，保护，控制，调查结果显示，数据通信一体化和人工智能化。

关键词：继电保护，继电保护现状发展，继电保护的未来发展一、继电保护原理及现状电力系统的迅速发展对继电保护不断提出新的要求，电子技术，计算机技术的快速发展不断为继电保护技术的发展注入新的活力，因此，继电保护技术是有利的，在40多年的时间里已完成发展了4个历史阶段。

建国后，我国继电保护学科、继电保护设计、继电器制造工业和继电保护技术队伍从无到有，在大约10年的时间里走过了先进国家半个世纪走过的道路。

50年代，我国工程技术人员创造性地吸收、消化、掌握了国外先进的继电保护设备性能和运行技术，建成了一支具有深厚继电保护理论造诣和丰富运行经验的继电保护技术队伍，对全国继电保护技术队伍的建立和成长起了指导作用。

阿城继电器厂引进消化了当时国外先进的继电器制造技术，建立了我国自己的继电器制造业。

因而在60年代中我国已建成了继电保护研究、设计、制造、运行和教学的完整体系。

这是机电式继电保护繁荣的时代，为我国继电保护技术的发展奠定了坚实基础。

自50年代末，晶体管继电保护已在开始研究。

60年代中到80年代中是晶体管继电保护蓬勃发展和广泛采用的时代。

其中天津大学与南京电力自动化设备厂合作研究的500kv晶体管方向高频保护和南京电力自动化研究院研制的晶体管高频闭锁距离保护，运行于葛洲坝50 0 kv线路上，结束了500kv线路保护完全依靠从国外进口的时代。

在此期间，从70年代中，基于集成运算放大器的集成电路保护已开始研究。
