中文摘要:
      模块化多电平换流器高压直流输电MMC-HVDC(modular multilevel converter based high voltage direct current)技术近年来得到迅猛发展,已成为解决新能源并网以及多端直流互联的有效手段之一,而高压直流断路器的缺乏已成为制约其工程应用的瓶颈之一。首先探讨了MMC-HVDC的双极短路故障特性;接着,对比分析了不同类型的直流断路器技术;然后,基于上述结果,在传统混合直流断路器基础上,提出了一种改进的混合式直流断路器方案,并详细分析了其工程过程;最后,通过仿真对其可行性和有效性进行了验证。
英文摘要:
      The technology of modular multilevel converter based high voltage direct current(MMC-HVDC)has been developed rapidly in recent years, becoming one of the most effective means for the gird integration of renewable energies and the interconnection of multi-terminal HVDC. However, the absence of a high-voltage DC circuit breaker has become one of the bottlenecks restricting its engineering applications. First, the bipolar short-circuit fault characteristics of MMC-HVDC are discussed. Then, different types of DC circuit breaker technologies are compared and analyzed. Afterwards, a modified hybrid DC circuit breaker scheme is proposed based on the traditional hybrid DC circuit breaker, and its working process is analyzed in detail. Finally, its feasibility and effectiveness are verified through simulations.
