10 kV配电网接线模式的可靠性评价研究

Study on reliability evaluation of 10 kV distribution network connection mode

为解决传统10 kV配电网接线模式可靠性评价置信度低的问题,设计10 kV配电网接线模式的可靠性评价方法。确定10 kV配电网接线模式的可靠性评价指标,计算10 kV配电网接线模式可靠性评价指标灰色关联度,构建10 kV配电网接线模式的可靠性评价荷载矩阵,通过评价公式,实现10 kV配电网接线模式的可靠性评价。实例分析结果表明,设计的评价方法置信度明显高于对照组,能够解决传统10 kV配电网接线模式可靠性评价置信度低的问题。

In order to solve the problem of low confidence in reliability evaluation of 10 kV distribution network connection mode,a reliability evaluation method of 10 kV distribution network connection mode is designed.The reliability evaluation index of 10 kV distribution network connection mode is determined,the grey correlation degree of 10 kV distribution network connection mode reliability evaluation index is calculated,and the reliability evaluation load matrix of 10 kV distribution network connection mode is constructed,reliability evaluation of 10 kV distribution network connection mode.The results show that the reliability of the evaluation method is significantly higher than that of the control group,which can solve the problem of low reliability evaluation of the traditional 10 kV distribution network connection mode.
