三端MMC-HVDC换流站直流母线双极短路故障特性分析OACSTPCD
Analysis on Characteristic of Bipolar Short-circuit Fault of DC Bus of Three-terminal MMC-HVDC Converter Station
对于柔性直流输电系统的双极短路故障问题,以三端基于模块化多电平换流器的高压柔性直流输电(mod-ular multilevel converter based high voltage direct current transmission,MMC-HVDC)为研究对象,阐述了MMC的工作原理及其直流母线主要故障类型,分析了换流器内部直流母线双极短路故障特性及短路电流计算方法,并搭建基于 PSCAD的三端MMC-HVDC系统,对其直流母线故障进行…查看全部>>
In allusion to the problems of bipolar short-circuit fault of HVDC flexible system,this paper states working princi-ples of modular multi-level converter (MMC)and the main fault types of DC bus by taking three-terminal MMC-HVDC for a research object. It analyzes characteristics of bipolar short-circuit fault of DC bus inside the converter and calculation method for short-circuit current. A three-terminal MMC-HVDC system for simulating on the fault is also es…查看全部>>
