Abstract
Aiming at the situation with different modes of distribution automations existing in the distribution network , this paper presents a method studying on the reliability evaluation of distribution network which contains multi-mode distribution automation. Firstly,with the help of the definition of regional node,a complex distribution network can be simplified into a network only composed of regional nodes and multi-mode distribution automation switch equipments. And a fast method of load transfer evaluation is proposed based on the simplified network. Secondly,characteristics of all distribution automations which have different influence on the reliability of distribution network is introduced. Fur⁃thermore,different kinds of distribution automations and corresponding failure influence states can be sorted. Finally, the set of fault enumeration nodes is defined in order to obtain the reliability parameters of the regional nodes. And the reliability parameters of load points and reliability index of distribution network can be calculated through a simple cor⁃rection. Example results show the correctness of the algorithm,which takes into account the influence of multi-mode dis⁃tribution automation with the same accuracy of failure mode effects analysis(FMEA)method.关键词
