摘要
客观分析影响配电网可靠性的相关因素是提高配电网可靠性的基础。从优化配电网结构出发,采用灰色关联分析方法.对平均供电半径、主干线平均负荷率、线路绝缘化率、双电源用户比例和平均每条线路开关数等配电网结构的指标进行关联度分析,以确定各相关因素影响配电网可靠性的程度。通过对某地区10 kV配电网的实例分析,验证了该方法可用。
To analyze objectively relevant factors of distribution network reliability is the base to improve the reliability of distribution network. Starting from structure optimization of distribution network, this paper conducts relational degree analysis on structure index of distribution network, like average power supply radius, average load rate of ske- leton lines, insulation rate of lines, dual power sources user rate and average switches number of each line etc, to decide to what extent each factor can affect the reliability of distribution network. This method is proven to be effective through the analysis on real cases of 10 kV distribution network in some region.
