| 摘 要： | 重合器式馈线自动化能有效提高配电网供电可靠性,对量化分析配电网可靠性的影响具有理论与实际意义。基于配电网分区思想重新划分配电网负荷区域类型,结合重合器式馈线自动化系统的概率模型及运行逻辑,根据供电恢复过程中各个阶段分段器的不同失效情况及其影响后果分析,推导不同类型负荷点的自动恢复供电概率与期望恢复供电时间,最终实现含重合器式馈线自动化的配电网可靠性指标量化评估。通过对算例的详细评估分析,验证了笔者所提模型的正确性和有效性。

| Abstract: | Feeder automation (FA) based on recloser could improve the reliability of distribution network effectively. Therefore, it''s important to quantatively analyze the impact of reclosing FA on the reliability of distribution system. Firstly, all load zone types are re-divided based on distribution network partition in this paper. Then according to the probability model and the control logic of reclosing FA, the probability and the time for automatic load restoration are derived based on detailed analysis of various outage modes and failure effect of sectionalizer in each stage of power service restoration. Finally, the formulas of reliability indices of distribution network with recloser feeder automation are achieved. The correctness and effectiveness of the proposed model are verified by examples. |
