Firstly, the types and characteristics of the common ground electrode used in HVDC system are analyzed in this paper. The effect of the common ground electrode to the HVDC transmission system and the environment are researched by modeling the common ground electrode with two High Voltage Direct Current (HVDC) transmission systems and analyzing the voltage variation (rise or down) of the neutral bus in converter station. Even more, the stability of the DC system is analyzed. Combining to the parameters of the Yunnan-Guangdong (YG) Ultra HVDC transmission system and Guizhou-Guangdong (GG) II HVDC transmission system, a detailed analysis of the effect of the common ground electrode to the DC transmission system is given. In addition, a comparison of the environment effect of the independent ground electrode and the common ground electrode to the DC system is presented in this paper, too. In the end, solving methods and suggestions to the corresponding negative effect are presented in this paper.
