摘要
为了保证柔性直流输电工程的可靠运行,在投入运行之前必须通过一系列试验来考察换流阀的安全可靠性,这就需要制定一套科学全面的型式试验方案来验证考核换流阀设计的正确性。针对模块化多电平换流阀(modular multilevel converter,M M C)的结构和工作原理,参考相关标准,以南澳多端柔性直流输电工程为例,研究提出了详细的M M C的型式试验方案,该方案能够较全面地验证基于MMC拓扑结构的换流阀及其相关电路设计的正确性。
In order to ensure the reliable operation of flexible DC transmission system,the safety and reliability converter valve should be completely checked by type test before operation. It demands a scientific and comprehensive type test scheme to verify and check the correctness of converter valve design. According to the structure and w orking principle of modular multilevel converter（ M M C） and relevant standards, w ith taking the Nan＇ao multi-terminal HVDC-flexible transmission project as an example,the type test scheme of M M C w as proposed,w hich could comprehensively verify the design correctness of converter valve and relevant circuit based on the topological structure of M M C.
