摘　　要：近些年,由于大量变频器和大功率非线性设备的应用,煤矿井下电网电能质量问题越来越突出,严重影响煤矿井下电网安全和煤矿正常安全生产。本文针对煤矿井下电网无功不足和谐波严重的问题,通过无功补偿技术和BP神经网络无功检测技术研究,研发了煤矿井下电网静止无功发生器。该设备应用将有助于提高电网电能质量,提升煤矿井下电网安全管理水平。In recent years, due to the application of a large number of frequency converter and high power nonlinear equipment, the power quality of coal mine underground power grid is becoming more and more serious, which seriously affects the safety of coal mine underground power grid and the normal safety production of coal mine. In this paper, for the problem of reactive power shortage and harmonic serious prob- lem in coal mine underground power network, by the reactive power compensation technology and BP neural network reactive power detection technology research, the research and development of static var generator. The application of this equipment will help to improve the power quality of power grid, and improve the safety management level of coal mine underground power grid.
