Improved Control Model for Relay Protective Settings Remote Control and Its Application

摘要

For a long time,settings' complexity makes the settings remote modification technology is difficult to be applied on the relay protective devices effectively.To solve the key technical problems of relay protective device's settings remote modification,this paper makes an in-depth research of setting group remote control model.The setting group remote control model based on protective relaying and fault information system is proposed with the setting group services mapping between IEC61850 and IEC60870-5-103.The setting group remote control model's working mechanism is deeply analysed via the setting group views.Base on the analysis,an enhanced control flow and task block method are provided to avoid the edit setting group data being changed abnormally,which improves the reliability of setting group remote control remarkably.The setting group remote control model introduced in this paper is applied successfully and its reliability is approved.
