Evaluation of Power Supply Reliability of Centralized Feeder Automation Distribution Network
摘要
Abstract
There were still some research gaps in reliability evaluation of distribution network considering central-ized 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 log-ic 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 con-figurations 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 meth-od in this study.The influences of different terminal configurations on reliability were compared.关键词
