摘要
煤矿电网供电电压偏低问题,给煤矿带来巨大电能损耗和经济损失,同时给井下工作设备的安全运行带来很大的危害.为了保证煤矿的正常生产,提出采用模糊综合评判与层次分析法相结合进行煤矿电网安全运行预警研究.实例分析表明,该方法可以准确判断电网电压状态及可能发展趋势.
According to the Low-voltage problem still in the coal mine power grid,it has huge energy loss and economic loss to the coal mine.At the same time,it also brings great harm to the safe operation of underground equipment.In order to ensure the coal mines normal production, proposed using fuzzy comprehensive evaluation and analytic hierarchy process to coal mine power network safe operation early warning research.Example shows that the method can accurately determine the state and the possible development trend of the grid voltage.
