| Abstract: | 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. |
