Abstract: Metro power dispatching monitoring system is a computer-based dispatching automation system for monitoring the equipment on the scene, so that the dispatching center can implement the functions of collecting data, controlling the equipment, measuring and adjusting parameters, alarming. This paper analyzed the metro power supply network, established the mathematical model of electrical equipment, used VC ++ programming technology to develop the operation interface of dispatching center, simulate the operation of on-site equipment, implement the function simulation of remote measurement, remote signalling, remote control and remote dispatching for the metro power dispatching monitoring system.
