摘　　要：从轨迹灵敏度指标的物理意义出发,在详细考虑了动态无功补偿设备实际特性的基础上,提出了一种基于改进轨迹灵敏度指标的动态无功优化配置方法。IEEE39节点系统算例和广东电网某区域220 kV网络算例的仿真结果验证了改进指标的有效性。最后,应用改进后的方法对南方电网"西电东送"交流通道的动态无功优化配置问题进行了研究。To enhance voltage stability of power system, it is an important and practical issue to determine the most suitable location for dynamic VAR compensators, however anslysis and simulation results show that the installation locations determined by the original trajectory sensitivity index are not necessarily optimal in some cases. According to the physical meaning of trajectory sensitivity index and considering actual characteristics of dynamic VAR compensator in detail, based on improved trajectory sensitivity index a configuration method for dynamic VAR compensators is proposed. Calculation and simulation results of IEEE 39-bus system and a certain regional 220 kV power network in Guangdong power grid show that the proposed method is effective. The proposed method is applied to the research on the configuration of dynamic VAR compensators in the HVAC transmission channel for power transmission from the west to the east in China South Power Grid.
