摘要
模块化多电平换流器的正常起动是柔性直流输电工程可靠运行的前提。针对目前起动策略控制时序及其时间定值整定方法相关研究较少的现状,本文依托厦门柔性直流输电工程提出了起动策略及时间定值整定方法。首先根据厦门柔性直流输电工程真双极接线的拓扑结构提出了自励起动策略;根据仿真及理论推导提出起动过程时间定值的整定方法;最后根据试验验证了起动策略和时间定值的有效性。
The normal start of the modular multilevel converter(MMC) is a prerequisite for reliable operation of HVDC flexible transmission project. At present, there are few researches on starting strategy and time value setting. Relying on the Xiamen HVDC flexible transmission project, this paper put forward the starting strategy. Then the time value setting method is proposed. Finally, the pre-charging experiments are conducted on MMC at Xiamen HVDC flexible project and the results prove the feasibility of the starting strategy and the time value setting method.
