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,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与可靠性参数及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,采用基于馈线分类的可靠性评估策略,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,验证了文中方法的有效性。
Abstract:
      The reliability improvement measures of distribution network are difficult to be quantitatively analyzed and horizontally compared. An evaluation and analysis method for reliability improvement measures of distribution network based on quantitative decomposition is proposed, in which reliability parameters are taken as intermediate variables to reflect the influence of reliability enhancement measures of distribution network on the reliability index. By establishing the relationship between reliability enhancement measures and reliability parameters as well as reliability index, the reliability index of distribution network is solved by explicit formulas. Considering that the node scale of the distribution network is large but the type is relatively simple, the reliability evaluation strategy based on feeder type is adopted to simplify the solution process. For the difference in the actual 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 different power grid conditions. Case studies of an actual power grid in China verify the effectiveness of the proposed method.
