【Abstract】 It is very important for any electric power system to make power net works safe and reliability .This paper presents a way to build electric power monitoring system based on PM Ⅱ PLC,and computer. The system consists of two mainstations and some substations, which are connected by ethernet and share information by network dynamic data exchange. The special characteristics of the monitoring system is that collecting field data and controlling equipment is implemented by means of PM Ⅱ and PLC. Windows 95 is used as the operating system, the system software has a friendly graphic user interface in which many functions such as dynamic data display, automatic accidents alarm, timed report print, on line information query and safe authority check are successfully implemented.更多还原
