The Design of Substation Avalanche Test System Based on B Code

This paper describes a substation avalanche test system which is based on B code. The system supports simultaneous operation of multiple remote signaling and can ensure the synchronization and accuracy of time´s movement. Using platform of ARM9 hardware and embedded operating systems, the system has lots of feature, such as high integration, small size and stable. The host computer can operate the device directly through the serial port, the operating parameters can be set and read from host computer. Analysis shows that the designed system can guarantee the stable of the operation of smart power grids devices.
