摘要
为给基于模块化多电平换流器（modular multi-levelconverter,MMC）的电压源换流器高压直流输电（voltagesourced converter HVDC,VSC-HVDC）换流阀提供有效的检验手段,以验证其设计的正确性及其运行可靠性,对换流阀的运行特性和关键应力进行分析,提出基于原理等效的MMC阀运行试验方法,设计试验电路并阐明其运行机理。搭建的PSCAD电磁暂态仿真模型和实际的试验验证证明了试验方法的正确性和有效性。
The modular multi-level converter based HVDC （MMC-HVDC） represents the development direction of VSC-HVDC. In order to ensure the operation reliability of the system, operational tests should be taken on the valves to investigate their tolerance to long-term operational stresses like current, voltage and heat. However, the current or voltage of MMC valves is a complicated combined ac-dc variable but not a single ac or dc variable, and the test methods of traditional HVDC valves are not suitable for the MMC ones.
