摘要
针对煤矿电网负荷端的低电压类型,选取了影响煤矿电网电压水平的8个因素,然后采用层次分析法建立了3层评判结构,给出了各层权重计算方法,并采用灰色理论与模糊综合评判的方法分析了各个因素的影响程度,从而得到对煤矿电网低电压发生可能性的准确评估。实例分析证明了该方法的有效性。
In view of low-voltage kinds of load side of coal mine power network, the paper selected eight influencing factors on voltage level of coal mine power network, then used analytic hierarchy process to build three-layer evaluation structure, gave calculation methods of weigh of each layer, and used the method of grey theory and fuzzy comprehensive evaluation to analyze influence degrees of each factor, which could get accurate evaluation of low-voltage possibility of coal mine power network. The example analysis proved the validity of the method.
