Abstract: It is an essential operation part of the flexible high voltage direct current transmission system when supplying the passive AC lines for a high proportion of new energy power plant without power transferred, which may lead to a high risk of resonances in the closed-loop operation control. For this scenario, a single voltage control loop with voltage and current limitation and resonance suppression abilities is proposed. The key factors causing resonance under the traditional single voltage control method are analyzed based on the consideration of time delay. Secondly, considering the requirements of fault voltage and current limiting and resonance suppression, a compensation control strategy with voltage and current feeding forward is proposed. The fault current relating with the output limitation of voltage controller and the equivalent DC gain of current feed forward compensator are derived. Thirdly, the analytic calculation and optimal design of the parameter's selection ranges of the feed forward compensator are presented to suppress resonance from different frequency bands. Finally, simulation models are used to verify the effectiveness of proposed strategy and the method of parameters calculation and optimization design.
