Adaptive VDCOL control strategy for the recovery of the UHVDC SPC system
The separating pole connection (SPC) mode of ultra-high-voltage direct current (UHVDC) can significantly improve the power stability, but when the AC bus of one pole is failed and two receiving systems are near, it may cause subsequent commutation ...

The HVDC commutation failure mechanism impacted by harmonics and its suppression method
Harmonics are an important cause of voltage distortion, and voltage reduction and voltage distortion are the main causes of commutation failure. But most of the current research studies on commutation failure are based on the drop in fundamental voltage ...
