Abstract

In the evaluation of the reliability levels of electrical power systems, reliability indices play a vital role. These indicators are System Average Interruption Duration Index (SAIDI), System Average Interruption Frequency Index (SAIFI) and Customer Average Interruption Duration Index (CAIDI). Statistical analysis of reliability indices of Ikeja and Port-Harcourt distribution system was carried out in this research paper.. Ten years of outage data information from ten selected distribution feeders of Ikeja and Port-Harcourt distribution systems were used in this work. The mean and standard deviation of the basic reliability indices were computed using appropriate mathematical relations as input parameters. Olowu feeder of Ikeja distribution system recorded the highest mean SAIDI of 01040 compared to all other feeders in the selected distribution system. Customers on this feeder were interrupted for a prolonged time while fewer of the customers were adequately served. 7-UP feeder of Ikeja distribution system had the least mean SAIDI of 0.0693 because customers’ interruption was for a short period of time even though; more customers were being served by the feeder. Airport of Port-Harcourt distribution system recorded the highest mean SAIDI of 0.1050. More customers were interrupted compared to all other feeders on the distribution system while fewer of them were adequately served. Airport feeder of Port Harcourt distribution system had a least mean SAIFI of 0.1392 because fewer of the customers attached to this feeder were interrupted while many of them were adequately served. The result of the work will provide a background information for distribution system engineers for adequate planning and effective maintenance of Ikeja and Portharcourt distribution systems. Keywords: Statistical analysis, Mean SAIDI, Mean SAIFI, Mean CAIDI, SAIDI standard deviation, SAIFI standard deviation, CAIDI standard deviation .

Ikeja和Port-Harcourt配电系统可靠性指标的统计分析

在电力系统可靠性水平评价中，可靠性指标起着至关重要的作用。这些指标包括系统平均中断时间指数(SAIDI)、系统平均中断频率指数(SAIFI)和客户平均中断时间指数(CAIDI)。本文对Ikeja和Port-Harcourt配电系统的可靠性指标进行了统计分析。在这项工作中使用了来自Ikeja和Port-Harcourt配电系统的10个选定配电馈线的10年停电数据信息。采用适当的数学关系作为输入参数，计算基本可靠度指标的均值和标准差。与所选配电系统的所有其他馈线相比，Ikeja配电系统的Olowu馈线的平均SAIDI最高，为01040。这条馈线上的客户被中断了很长时间，而较少的客户得到了充分的服务。Ikeja配电系统7-UP馈线的平均SAIDI最小，为0.0693，因为客户中断的时间较短;更多的顾客被喂食器服务。港-哈科特运输系统的机场平均SAIDI最高，为0.1050。与配电系统上的所有其他馈线相比，更多的客户被中断，而更少的客户得到充分的服务。Harcourt港分配系统的机场支线的平均SAIFI最小，为0.1392，因为连接到该支线的客户较少被中断，而许多客户得到了充分的服务。这项工作的结果将为配电系统工程师提供充分规划和有效维护Ikeja和Portharcourt配电系统的背景资料。关键词:统计分析，平均SAIDI，平均SAIFI，平均CAIDI, SAIDI标准差，SAIFI标准差，CAIDI标准差出版日期:2019年5月31日
