非线性交流故障电弧电阻对LCC-HVDC系统换相失败的影响

Commutation failures (CFs) in LCC-HVDC systems are typically caused by inverter-side ac line faults. Historically, since the fault arc resistance has been simplified to a fixed resistance in related studies, possible ac arc-induced bus voltage distortions have not been sufficiently studied. This letter investigates the impact of nonlinear ac fault arc resistance on CFs. Specifically, transient exp...
