摘要
Abstract
Research on grid structure in domestic at present is concentrated in connection mode while study on ring-type pow-er supply model is in start-up phase and there is no relatively perfect scheme for configuration and setting of secondary pro-tection system of the ring-type power supply model which may restrict development of the ring-type power supply model. Based on this,a kind of protection configuration and setting scheme for typical ring-type power supply model which could control short-circuit current level was proposed.In aspects of primary structure of the model,protection configuration,set-ting of backup time range,protection disconnection,principles of in service and out of service and configuration of automat-ic switch of wide-area backup power source,the setting scheme was studied and specific and feasible scheme was proposed.关键词
