Abstract: According to actual situation of 10 kV distribution network, this paper carried out the system simulation calculation for the impact of post-set arc suppressing coil on safety operation of distribution network and evaluated its advantages and disadvantages.This paper raised a new type of tuning method of arc suppressing coil. 40% detuning degree was preset in normal operation of postset arc suppressing coil. Simulation result shows that the new type of tuning method has solved the low successful rate problem of existing system widely applied in post-set arc suppression coil fault line selection, which is favorable for safety and reliable operation of distribution network.
Key words: arc suppressing coil; under compensation; intermittent arc grounding; grounding line selection; evaluation and optimization
