摘要:随着自动化技术的发展,地区电网电压无功自动控制得到了广泛的推广应用。该文分析了近年来电压无功自动控制技术的发展,重点介绍了变电站电压无功控制装置(VQC装置)、电压无功集中分析集中控制(AVC)系统的技术思路。该文提出,对于调度自动化主站+若干集控站的调度运行管理模式应当采用分布式AVC系统;应当考虑省级电网、地区级电网、县级电网的电压无功分区分层分级联合协调控制,在有条件的地区同时还需将10kV线路无功补偿自动装置通过无线通讯技术纳入全网优化协调控制;做好电压无功控制的前提之一是做好无功补偿设备的规划。

ABSTRACT:Area work atuomation control technology of reactive and voltage prhensively popularized and applied with the development of automation document analyzes the development of area work atuomation control technology of reactive and voltage in recent years . It concentrates on the description of voltage/reactive control apparatuse in substation (VQC apparatuses) and technology idea of reactive/voltage-concentrator-analysis-and- concentrator-control system(AVC).Further more,this document puts forward that the distributed AVC system should be applied to the running management pattern of dispatch,which bases on the primary station of SCADA plus a number of concentrator -layering-grading associated control of reactive and voltage control i
