摘　　要：贵州大方煤业有限公司小屯煤矿为煤与瓦斯突出矿井,矿井两路35kV电源分别引自110kV新铺变电站和六龙变电站,分属不同电网,不能合环操作,该地区属雷电多发区,受雷击及其它因素影响易引发系统性电压波动,造成非正常停电、电压大幅波动或短时断电(俗称"晃电")的情况屡见不鲜,一旦停电很容易造成瓦斯积聚,带来严重的后果。因此,供电电源不间断可靠性技术研究尤为有重要意义。The Xiaoyu Coal Mine of Guizhou Dafang Coal Industry Co., Ltd. is a coal and gas outburst mine. The 35 kV power supply of the two mines is taken from the 110 kV Xinpu Substation and the Liulong Substation respectively. It belongs to different power grids and cannot be operated in a loop. The area is lightning-prone. District, due to lightning and other factors, it is easy to cause systemic voltage fluctuations, resulting in abnormal power outages, large voltage fluctuations or short-term power outages(commonly known as "shaking electricity") is not uncommon. Once power outages are likely to cause gas accumulation, serious As a result, the research on the uninterrupted reliability technology of power supply is particularly important.
