Theory and Simulation of Supplementary Damping Control for Unified Power Flow Controller to Mitigate Subsynchronous Resonance
摘要
Abstract
With the widespread application of series compensated capacitors , the power systems are facing the severe problem of subsynchronous resonance ( SSR) in China . To solve the SSR problem , a method of supplementary damping control for unified power flow controller ( UPFC) is proposed based on the UPFC with current control mode . The positions of supplementary subsynchronous damping signal accessing to UPFC controller are chosen at first . The UPFC supplementary subsynchronous damping controller ( SSDC) is designed , and the principle how to damp SSR is deduced as well . Besides , the mode‐splitting control is used in the designed SSDC to mitigate the multi‐modal SSR . Finally , the complex torque coefficient and time domain simulation are both performed to analyze and verify the effectiveness of damping SSR with the designed SSDC . Meanwhile , the simulation results also suggest that the designed SSDCs have none negative effect on the performance of UPFC and the system .关键词
