Study on Zhongmou 500kV High Voltage Substation Monitoring System Based on Bluetooth Technology

The power structure of main electrical wiring diagram outgoing line in Zhongmu 500kV substation is analyzed firstly, and then the substation communication system based on Bluetooth technology was put forward in this paper. The power and critical loads are important, the connection lines and the connection modes in the substation are very complicated. Bluetooth technology can replace wired cable connection with the wireless interface in the short distance, prevent from complicated line in industry. This paper analyzes and designs model of the network in the substation, enhancing the automatic and intelligence level. Substation monitoring system was composed of meters, relays and other communication devices with Bluetooth components. The structure of the system can be divided into three layers, the bottom is monitor， the terminal in high-voltage chamber is the middle layer, the central processor in Control Building is the most top, bottom communicate with middle layer by Bluetooth technology.The system architecture, software, hardware and the necessary factions of this system are introduced.
