摘要
基于电压分层控制及无功源区域性分布的特点,结合现代电网调度自动化系统(EMS)的一体化调度需求,阐明了省地自动电压控制(AVC)系统协调控制原理,提出了一种适合省地AVC系统联合优化的协调控制技术方案,并分别探讨了省调侧和地调侧的控制策略以及它们之间通信方案的实现。经实际系统的工程应用表明,所提出的技术方案和控制策略是可行且有效的,较好地解决了当前省地AVC控制系统之间的协调问题。
Based on the voltage hierarchical control and reactive source regional distribution characteristics and the scheduling needs of modern power grid energy management system（EMS）,the principles of coordinated AVC for provincial power network are clarified and a joint optimization scheme for coordinated AVC for provincial power network is proposed.Besides,the control strategies of AVC in the provincial and the municipal control side are discussed and the realization of communication scheme between them is also given.The practical applications of actual power system shows that the proposed technical scheme and control strategy are feasible and effective,which can solve the current coordination problems of AVC for provincial power network better.
