    摘要
  • 摘要:
      目的  供电可靠性是衡量电力企业供电服务质量的重要考核指标之一。为了分析配电网不同供电可靠性提升措施的实施效果，需要精确定位提升配电网供电可靠性的主要影响因素。
      方法  文章在传统的配电网可靠性估算方法的基础上，充分考虑配电自动化及配电网转供电能力的影响，提出了供电可靠性影响因素灵敏度计算方法。
      结果  构建典型农村配电网架和城市配电网架，开展供电可靠性影响因素灵敏度计算和分析。
      结论  所提充分考虑了影响供电可靠性的主要因素及影响机理，可为开展供电可靠性规划和配电网升级改造提供技术方向指引。

     

    Abstract:
      Introduction  Power supply reliability is one of the important evaluation index of power supply company. The paper aIms to analyze the implementation effect of different power supply reliability improvement measures in distribution network, so it is necessary toaccurately locate the main influencing factors of improving the power supply reliability of distribution network.
      Method  Based on the traditional reliability estimation method of distribution network, the paper fully considered the influence of distribution automation and power transfer capability of distribution network, and proposed a sensitivity calculation method of power supply reliability influencing factors.
      Result  The paper buildt typical rural and urban distribution grids, and carried out sensitivity calculation and analysis of factors affecting power supply reliability.
      Conclusion  The paper fully considered the main factors affecting power supply reliability and the influence mechanism, which can provide technical direction guidance for power supply reliability planning and distribution network upgrading.
