In order to accurately and effectively solve the problem of capacitive current exceeding the standard in the current distribution network, this paper proposes a combining reactive compensation method of distributed fixed and centralized tracking for the 10 kV ungrounded system. The problem of capacitive current and conventional reactive compensation is analyzed by using data instance and mathematical statistics method, and the solution of decentralized fixed and centralized tracking is given. Using the method of Matlab/Simulink to simulate the solution, the results show that the proposed method is effective and practical for solving the problem of capacitance current exceeding 10 kV ungrounded system by using the combination of distributed fixed compensation and centralized tracking compensation. Meanwhile, this scheme has a certain significance to the planning and design of the substation, and the reactive power configuration of 10 kV opening and closing station.
