Reliability-based Planning Method for Shared Spare Distribution Transformers
摘要
Abstract
With the consideration that the existing researches on shared spare transformers do not take the diversity of load into account,a reliability-based Markov model and a shared spare planning model for distribution transformers are established in a shared spare mode. Furthermore,the minimum of random failure outage loss cost,spare investment cost,and replacement cost is taken as an objective function,thus a shared spare planning model is formed for distribu-tion transformers,which is further solved using enumeration method. The transformers in Roy Billinton Test System (RBTS)Bus2 system are analyzed as an example:the economical indexes with different spare numbers are compared to obtain the optimal spare plan;meanwhile,sensitivity analysis of replacement time is also conducted.The validity and effectiveness of the proposed method are verified through the analysis of the numerical example.关键词
