最近提出的网状高压直流输电网络既包括变流器也包括直流断路器，并且所经历的故障电流和断路器的容量需求取决于网络中使用的变流器的拓扑结构。本文分析了采用故障馈电和故障阻断转换器的各种网络配置中故障电流的差异。结果显示，在已经实施故障限流转换器的直流网络区域中看到的故障电流减少，这可能对拓扑结构、电流额定值以及断路器的尺寸和成本产生影响。
Recently proposed meshed HVDC networks include both converters and DC circuit breakers, and the fault currents experienced and therefore the capacity requirement of circuit breakers are dependent on the topology of converters used on the network. This paper analyses the difference in fault currents seen in various network configurations utilising fault-feeding and fault-blocking converters. Results are presented showing the reduced fault currents seen in the regions of the DC network where fault current limiting converters have been implemented, which could have an impact on the topology, current rating and therefore size and cost of the circuit breaker.
