摘要
Abstract
Cascaded multi-terminal DC (MTDC) transmission technology, which is utilized as the typical connection mode for multi-terminal HVDC transmission projects, possesses good development prospect. Based on research results of overvoltage in ±800 kV cascaded MTDC transmission system, the insulation coordination for cascaded multi-terminal UHVDC transmission system is researched, and the obtained results are compared with that for conventional ±800 kV UHVDC transmission system. Comparison shows that except ±400 kV medium voltage lines in cascaded MTDC transmission system, the insulation coordination for the rest of substation equipments and lines can be complied with those for conventional ±800 kV MTDC transmission system.关键词
