摘　　要：介绍了粤北电网在线预决策稳定控制系统的设计、运行原理及实施情况,并提出新的设想。该系统采用动态开断潮流法进行静态安全分析,采用匹配关键节点状态和网络拓扑结构的方法进行状态估计。通过实时数据仿真分析证明,该系统在确保电网暂态稳定和静态安全满足要求的同时,可实现追求最小综合控制代价的目标。该系统显著提高了粤北电网的送出能力,且具备一定的适应电力市场环境的能力。Design,operation principle and implementation of online pre-decision stability control system for North Guangdong Grid is introduced,and a new assume is put forward.Dynamic breaking power flow algorithm is used in analysis of static state security,matching method for key node state and network topology is adopted in state estimation.Through simulation of real-time data,it is proved that,considering the power system transient stability and static state security can meet a demand,this system can also take the total control cost as the objective function.This system can increase the transmission capability of North Guangdong obviously,can be used in electricity market environment.
