摘要
以具体工程为例,介绍分级式可控并联电抗器的控制策略和保护配置。从分级式可控并联电抗器的基本构成出发,详细说明了其各个部分的组成以及在整个装置中的功能作用,从理论上解释了可控并联电抗器的工作方式和原理,并给出了相应的无功容量计算公式。在控制系统性能要求方面,详细介绍了控制系统的设计方案和控制策略的原理及实现方式,并重点说明了容量切换的方法和步骤,以及该控制方式的优点;介绍了保护系统的配置,主要说明了阀保护和断路器保护及暂态保护的接线方式、原理及保护动作方式,最后根据忻都500kV可控并联电抗器示范工程的系统试验来说明该控制保护系统的性能。
Taking a specific project as an example,the control strategy and protection configuration of the step controlled shunt reactor (SCSR) are presented. Starting from basic structure of SCSR,the composition of the various parts and their respective functions are introduced,and its working method and principle in theory are explained,with corresponding formula for calculating the reactive power capacity as well. Furthermore,as viewed from the performance requirement for control system,the operation principle,implementation for the design scheme and control strategy of the control system are detailed. And the method and procedure for capacity switching as well as the advantages of the control method are highlighted. This is followed by configuration of the protection system,with focus on the wiring,principle and protection method for valve protection,circuit breaker protection and transient protection. Finally,the performance of the control and protection system is illustrated with the system test of Xindu 500 kV controlled shunt reactor pilot project.
