摘要
控制交互作用对整个控制系统的性能影响是致命的,因此控制器的设计及其协调在现代电力系统应用研究中是一个重要课题。文章结合目前在国内外技术上应用较成熟的静止无功补偿器(SVC)技术,提出一种与变电站综合自动化系统配合的变电站无功补偿系统改造方案,采用区域无功电压优化控制系统(AVC)统一对操作站的无功补偿设备(FC-TCR型SVC)进行无功电压优化控制,使其能统一接入变电站综合自动化系统,克服了以往变电站中无功补偿系统只能单独通过控制器的控制策略孤立运行及控制器间交互影响的问题。最后通过仿真验证了提出的方案及控制策略的可行性,仿真显示系统具有良好的动静态性能。
The interaction between controllers is fatal to the whole control system.The design and its coordination of controllers is an important task in the application research of modern power system.In this paper,a modification solution of reactive power compensation system of substation coordinated with integrated automation system of substation is proposed with combination of presently mature static var compensator（SVC） technology both at home and abroad.Reactive voltage optimization control of reactive power compensation equipment（type FC-TCR SVC） of substation is carried out by the use of regional reactive power voltage optimization control system（AVC） and it can be completely accessed to the integrated automation system of substation,overcoming the problem of controller＇s interaction between isolated operation and the shortcoming of previous substation in which reactive power compensation system can only be in the control strategies alone through the controller.The proposal and feasibility of control strategy is verified through simulation and it is shown that the simulation display system has perfect dynamic and static performance.
