摘要
Abstract
The closed-loop operation mode and features of medium voltage distribution networks at home and abroad are described.With both reliability and economy considered,a net profit model for upgrading the distribution network from open-loop operation to closed-loop operation is developed,including a simplified evaluation model of system average interruption duration index(SAIDI) for a medium voltage cable feeder.The difficulties and applicable scopes of closed-loop operation are discussed.The study results show:i)further improvement of power supply reliability is impeded because of the existing power supply mode of closed-loop design and open-loop operation for domestic distribution networks;ii) for areas of developed economy,large load density,distributed generation and high reliability requirement,the closed-loop operation mode (mainly one of two feeders from the same bus) can be considered for use conditions permitting.Despite a higher cost for the power supply company owing to the use of the closed-loop operation mode,power supply reliability is improved while good social and economic benefits are ensured at the same time.关键词
