中文摘要	The HVDC transmission system may be operated in ground return mode when the system is in debug or failure. The disadvantages, such as audible noise, harmonic and oscillation ol the transformer in AC systems, are illustrated by analyzing the data of LONG ZHENG, TIAN GUANG and SAN GUANG HVDC system. And field experiments were implemented by measuring the neutral DC current of more than ten translormers when the GUI GUANG HVDC system was in debugging. Some useful data were acquired and some interesting results wenoh tained by analyzing these data. Based on the field circuit theory model, the DC ground current flowing through the neutral point of the transformer was analyzed, and the restdt verified the feasibility of the theoretical model.
