  • Calculation and control of DC bias current distribution in

    Abstract. Read online. When the ultra-high-voltage direct current (UHVDC) transmission system operates in a monopolar ground return mode, an enormous DC current flows into earth via the DC grounding electrode in the converter station and then comes into the AC system around the converter station through the neutral earthed transformers, which will cause DC bias in AC systems and harm
