摘要：
Due to the difference between MMC-HVDC and LCC-HVDC control characteristics and the mutual influence under parallel connection, the power modulation strategy of MMC-HVDC is different from that of LCC-HVDC. The coordinated control strategy of parallel system of MMC-HVDC and LCC-HVDC is analyzed, and the implementation methods of power dispatching and speed rate dispatching for power limitation function and reactive power control are expounded. Combined with RTDS simulation research of modulation function of Luxi back-to-back HVDC system, the control characteristics of power limitation function of the parallel system under the condition of AC fault at the receiving end are analyzed in view of the exposed defects. A coordination method of power limitation function and high-voltage ride-through control function and an optimization method of speed rate dispatching of power limitation function are proposed. Simulative results show that the optimized parallel system can perform power limitation function at a correct timing sequence and speed rate. © 2019, Electric Power Automation Equipment Press.
