Decoupling control algorithm was designed, decoupling control model was given and simulated. Simulation results show that with optimized control parameters, 3-phase currents of chain circuit STATCOM have good tracking performance and control precision in d-q-0 coordinates, both in a-b-c coordinates and in d-q-O coordinates current control has excellent fast tracking performance, that shows the current regulator design method and parameters setting are feasible and effective.
