Resistor-Capacitor Combined DC Bias Protection of AC Power Grid of Jiuquan-Hunan ±800 kV Transmission Lines
DC bias was observed in transformers of the ac system surrounding Jiuquan-Hunan ±800 ultra-high voltage direct current (UHVDC) transmission lines in China, which were operating in the simulation of the unipolar-earth ground mode. Applying conventional dc bias protection methods in this ca...
