Aiming at the technical problems of power overshoot and AC bus voltage fluctuation in the process of reactive power compensation of high voltage converter station,by considering the influence of reactive power disturbance,an advanced control method of double closed loop condenser with AC bus voltage outer loop and reactive power of synchronous condenser inner loop is designed.The control method can effectively suppress the reactive power overshoot while ensuring the rapid response of the condenser to the AC bus voltage fluctuation.In order to further suppress the large fluctuation of AC bus voltage caused by reactive power fluctuation in high-voltage converter station,a coordinated control strategy of condenser and AC bus capacitor reactive power compensation is designed and implemented by means of capacitor series connection to absorb resistance,which improves the steady-state and dynamic performance of high-voltage converter station.The correctness and effectiveness of the proposed control method are verified by PSCAD software.
