摘要
子模块电容电压的稳定对MMC稳定运行至关重要。随着MMC电压等级提高,子模块数量逐步增大,传统排序均压算法难以满足控制要求。针对这种情况,提出一种适用于高电压等级的子模块电容电压分组的均压控制算法,所耗资源和时间大大减少,并且能够达到与排序均压相同的均压效果,减轻了阀控系统的设计难度,提高系统可靠性。
Capacitance voltage stabilizer module is essential for MMC operation stability. With large number of sub-modules caused by voltage rating increase, traditional sorting algorithms cannot meet control requirements. A capacitor voltage sub-module packet equalizing control algorithm suitable for high voltage level is proposed. The algorithm can greatly reduce resource consumption and calculation time with the same result as traditional method. It also simplifies the valve system design complexity and improve system reliability.
