Parallel Setting Algorithm Research for Coalmine High Voltage Grid Based on First-Come-First-Serve

In order to meet the requirement of time overhead of on-line setting and checking system of high voltage grid in coalmine, when the number of high voltage switches in high voltage grid of coalmine is more, it is necessary to solve the problem of reducing the time overhead of setting the relay protection of all high voltage switches in the whole mine high voltage power supply system. In order to improve the efficiency of setting calculation, this paper presents a parallel setting calculation method for high voltage power supply system in coalmine. According to the obtained topology analysis model, parallel setting calculation of all high-voltage switch branches of high-voltage power supply system in coalmine is realized based on the first-come first serve parallel scheduling strategy. The simulation results show that the proposed method can effectively reduce the time overhead and improve the computational efficiency.
