摘　　要：通过仿真计算,研究了静止无功补偿装置(SVC)对河南电网断面输送能力的影响,利用极限功率搜索和扩展等面积(EEAC)理论所提供的暂态稳定裕度灵敏度方法对不同的SVC安装地点进行了比较。比较结果表明,SVC能提高系统的暂态稳定水平。基于强化学习算法,设计了SVC的控制器。数字仿真表明,其对暂态和动态稳定的控制能力都优于PID控制。Effect of Static VAR Compensator （SVC） on the transmission capability of Henan grid was analyzed by digital simulation. Various locations of SVC were investigated using limitation scanning and the sensitivity of transient stability margin provided by EE- AC. A SVC controller based on reinforcement learning was also presented. It is proved that SVC can improve the transient stability. Digital simulation demonstrates its better pertbrmance on transient and dynamic stability than PID controller.
