摘　　要：在比较电压源型换流器(VSC)与传统换流器的基础上,讨论了基于VSC的高压直流输电系统的结构与原理,分析了其功率特性、谐波特性、控制特性以及运行方面的特点,并指出了需要进一步研究的问题。分析表明,VSC控制和运行方式简单,输出波形品质好,运行模式灵活,具有良好的发展前景。By comparing Voltage Source Converters (VSCs) to conventional convener, the structure and mechanism of VSC- based HVDC are presented. The power characteristics, harmonics, operational and control characteristics are also analyzed, and some problems in the application are pointed out. The analysis indicates that, with their ideal control and operational characteristics, perfect output waveform and flexible operation, VSCs will be applied widely in HVDC power transmission.
