Research on Main Circuit Scheme of VSC-UHVDC
摘要
Abstract
Voltage sourced converter based high voltage direct current ( VSC-HVDC) with ±800 kV/5000 MW ultra-high voltage and large-capacity level is an important development direction of HVDC technology.Considering the development status of VSC-HVDC technology, the advantages and disadvantages of converter configurations with symmetrical monopole wiring and symmetrical bipolar wiring are compared.For the ±800 kV/5000 MW VSC-HVDC technology, the device characteristics and operation perform-ance of single converter scheme and double converter scheme under symmetrical bipolar wiring are compared and analyzed.The analy-sis results show that the double converter scheme is more suitable for the ultra-high voltage, large capacity and long distance VSC-HVDC technology because of its more flexible operation modes and higher energy availability.关键词
