为解决传统三级电压控制中省调自动电压控制(automatic voltage control,AVC)直控500 kV 变电站的方案所带来的信号采集与站端改造工作量大、省调调度员的监视工作压力等技术和管理难题,提出一种“省调AVC 全局优化下发控制需求,地调 AVC 直控”的分布式智能协同控制方法。该方法是三级电压控制体系架构在工程实施上的一种创新实现,既能保证电压无功全网协调优化,又减少了工程实施难度和运维工作量,减轻了运行管理的工作压力。在广东电网顺德、圭峰、祯州、香山四个试点500 kV 变电站应用实施,验证了该方法的可行性和有效性。

In order to solve technical and management problems of heavy workload of signal acquisition and station end trans-formation as well as heavy monitoring working pressure for provincial dispatchers caused by direct control on 500 kV substa-tion by provincial automatic voltage control (AVC)of traditional tertiary voltage control method,a kind of distributed in-telligent coordination and control method of provincial dispatching AVC realizing overall optimization and regional dispatc-hing AVC realizing direct control was proposed.This method was a new innovation in engineering implementation of tertia-ry voltage control system which could not only ensure coordinated optimization of voltage reactive power in the whole power grid but also reduce difficulties of engineering implementation,workload of operation and maintenance and working pressure of operation and management.Application in four pilot 500 kV substations of Shunde,Kuifeng,Zhenzhou and Xiangshan of Guangdong power grid verified feasibility and effectiveness of this method.
