MMC与LCC换流变分接头控制策略的比较分析

Comparative Analysis of Tap Changer Control Strategy of Convector Transformer between MMC and LCC

结合鲁西换流站实际情况,介绍了柔性直流(MMC)和常规直流(LCC)换流变分接头的控制原理和控制策略,并对这两种分接头控制策略的优缺点进行了比较,为今后新建柔性直流和常规直流并联运行的背靠背工程提供参考。

Combining with actual situation of Lu-xi convertor station, control principle and control strategy of convertor transformer tap changer of flexible HVDC（MMC） and conventional HVDC（LCC） are introduced. Advantages and disadvantages of control strategies between two kinds of tap changers are compared, which provides reference for future back-to-back project with parallel operation between flexible HVDC and conventional HVDC.
