重庆北部新区配电网供电可靠性薄弱环节分析

Weak Link Analysis of Power Supply Reliability of Distribution Network in Northern Newly Developed Area of Chongqing

为了顺应供电可靠性管理由事后统计评价向事前预测评估转变的趋势,国家电网公司牵头制订了行业标准《中压配电网可靠性评估导则》。导则指出评估过程应直接导入现有的GIS、PMIS数据避免人工干预,为此利用配电网规划计算分析软件DPCAS计算出重庆市北部新区配电网的可靠性指标,并根据评估结果对系统供电薄弱环节提出了相应的改善措施。计算结果表明提出的改善措施能够明显提升该区供电可靠性。

In order to comply with the trend that the reliability management of power supply turns from afterwards statistical e -valuation to forecast evaluation , the State Grid Corporation takes the lead to develop the industry standards , that is,＂Reliabil-ity Evaluation Guideline for Distribution System of Medium Voltage＂.The standards point out that the assesmnet process should import the data from the existing GIS and PMIS data to avoid manual intervention .Therefore, DPCAS （ distribution planning calculation analysis software ） is adopted to evaluate the reliability index of distribution network in northern newly de-veloped area of Chongqing .Based on the assesment results , some improvement messures are proposed .The calculation results indicate that the proposed measures can significantly enhance the reliability of power supply .
