[0002] The basic structure of the power dispatching automation system includes the information acquisition and command execution subsystem, the information transmission subsystem, the information collection, processing and control subsystem, and the human-machine contact subsystem. The information acquisition and command execution subsystem is a telecontrol terminal installed in the power plant and substation, which cooperates with the master station to realize the four remote functions, namely telemetry, telesignaling, remote control, and remote adjustment. Among them, telemetry is remote measurement, and the operating parameter data of the monitored power plant or substation is transmitted from the telecontrol terminal to the master station.
