摘要:
计及集中式馈线自动化的配电网可靠性评估尚存在较多研究空白,且多数研究仅计及故障停电的影响, 在考虑预安排检修容量约束的情况下,计及负荷转供影响,结合馈线自动化的类型及运行逻辑,依据馈线自动化相 关技术指标,对恢复供电过程中出现的负荷点进行详细分类,推导出不同类型负荷期望恢复供电时间和配电网供 电可靠性指标计算公式。 结合算例进行分析可知,不同终端配置 下 馈 线 系 统 平 均 停 电 持 续 时 间 SAIDI 可 减 少 0. 95 ~ 1. 08 h / (用户·a) ,说明了优化终端配置可有效提高配电网供电可靠性,证明了所提评估方法的准确性和实 用性,并比较了不同终端配置对可靠性的影响。
Abstract:
There were still some research gaps in reliability evaluation of distribution network considering centralized feeder automation, and most studies only focused on the impact of power failure. Considering the pre-arranged maintenance and capacity constraints, the influence of load transfer, and combined with the type and operation logic of feeder automation, according to the related technical indexes of feeder automation, the load nodes appearing in the process of power restoration were classified in detail. And the calculation formulas of expected power restoration time and power supply reliability indexes of different types of loads were derived. Combined with an example, the average outage duration SAIDI of feeder system was reduced by 0. 95-1. 08 h / ( user·a) with different terminal configurations in the example, which showed that optimized the terminal configuration could effectively improve the power supply reliability of distribution network, which proved the accuracy and practicability of the evaluation method in this study. The influences of different terminal configurations on reliability were compared.
