Abstract:Aiming at the problem that the position power system has not realized remote centralized monitoring, the centralized monitoring system for cross platform transmission of power system data is designed, multi-level redundancy is set to improve system reliability; the field data acquisition interface software is made to realize the field data acquisition; the local power monitoring system , Kepserverex opc server and WinCC platform server are configured to realize cross platform data transmission between local power monitoring system and Siemens WinCC monitoring platform; the substation overview display, HV parameter display, LV parameter display and DC screen monitoring functional modules are developed to realize remote centralized real-time monitoring of main data; it is verified that it can meet the performance requirements for correct information display, short response time, quick return, etc.
