摘要:
      针对当前不同配电网可靠性提升措施分析中定量分析不足、难以横向比较的问题,本文提出了一种基于量化分解的配电网可靠性提升措施分析方法。以“可靠性参数”为中间变量,研究配电网可靠性提升措施对可靠性指标的影响,通过建立配电网可靠性提升措施和可靠性参数、可靠性参数与可靠性指标之间的关联关系,以显式公式形式实现配电网可靠性指标的求解。考虑到配电网的节点规模大但类型相对较为简单,采用基于馈线类型的可靠性评估策略,简化了求解过程。针对实际电网规模、管理制度,以及通信环境、设备基础的不同,引入可靠性提升措施实施度修正参数,以消除由于电网情况不同而带来的差别。通过国内某实际电网算例分析,验证了本文方法的有效性。
Abstract:
      The distribution network reliability improvement measures are difficult to be quantitatively analyzed and horizon-tally compared. A reliability improvement measures evaluation and analysis method for distribution network based on quantitative decomposition was proposed in the paper, which takes "reliability parameters" as an intermediate variable to reflect the influence of distribution network reliability enhancement measures on reliability index. By establishing the relationship between reliability enhancement measures and reliability parameters, the reliability index of distribution network is solved by explicit formula reliability parameters with reliability parameters. The reliability evaluation strategy based on feeder type is adopted to simplify the solution process. According to power grid scale, management system, communication environment and equipment foundation, some implementation correction parameters of reliability improvement measures are introduced to eliminate the difference caused by dif-ferent power grid conditions. At last, case studies of a practical power grid in southern China are used to verify the feasibility and effectiveness of the proposed method.
