摘要：
Nowadays, an increasing number of grid is adopting resonant grounding method. Only accurately detecting the capacitive current, could we play the advantages of resonant grounding. The most popular method in the field is the tuning method, which includes two-point method and three-point method. This paper analyzes the principle of two-point method and identifies a major problem in the application of two-point method. A stall of two-point method stays in the state of overcompensation while another stall stays in the state of under compensation, which has not been taken into account. Finally, the paper verifies the effect of proposed improvements using MATLAB simulation.
