Calculation and control of DC bias current distribution in an AC power system around a typical ±800 kV DC grounding electrode

Calculation and control of DC bias current distribution in an AC power system around a typical ±800 kV DC grounding electrode

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 earthe...
