摘要
Abstract
A multi-device coordinated fault recovery method is proposed for the N-1 and N-2 fault scenarios of multi-transformer flexible interconnected transformer.Firstly,the characteristics of trans-former N-1 and N-2 fault scenarios and the coordinated fault recovery process of bus coupling switch and SOP in distribution station under each scenario are sorted out;secondly,considering the constraints of network operation and equipment capacity in the process of fault recovery,a fault recovery model of flexi-ble interconnected distribution network with the goal of maximizing load weighted recovery is established,and it is transformed into second-order cone solution;finally,the effectiveness of the proposed method is verified in a typical low-voltage distribution network topology with 21-node+21-node flexible intercon-nection,which proves that it can effectively improve the ability of important loads to guarantee power sup-ply after transformer failure.关键词
