| Abstract: | The safety and reliability of highway power supply system is an important foundation to ensure its mechanical and electrical equipment running normally and operating smoothly for itself. A supervisory control and data acquisition （SCADA） system is presented according to the characteristics and concrete conditions of highway power supply system. PLC is used to monitor and control power supply systems of power stations along highway, computer is used for the management of the monitor and control stations in key sections of the highway as well as for the management of center. Network technology is applied to make whole system forming a automatic distributed control system that can meet the needs of automatic development for modem highway. |
