水路及均压电极布置方式对MMC换流阀阀端间交直流耐压试验的影响研究
Gaoya dianqi, 2022 MMC换流阀阀端间交直流耐压试验时，换流器闭锁，电容电压控制算法未投入使用，因此，子模块的均压特性受系统阻容网络的影响。根据试验录波结果，阀塔层间子模块电压分布规律为顶层和底层高，中间层低，子模块电压先发散，后趋于平衡。经过分析得到水路及均压电极布置方式对系统阻容网络有很大的影响，是试验过程中造成层间子模块不均压的主要因素。通过搭建MMC换流阀阀端间交直流耐压试验详细仿真模型，仿真得到层间子模块电压分布规律与试验基本一致，10 s试验最大不均压度为3.9%,3 h试验最大不均压度8.9 ...
