The Design of the Permanent Magnet Vacuum Circuit Breaker Control System Based on SOPC

This paper analyzes the instantaneous value of the three-phase circuit measurements of various parameters and the key issues to be addressed , to design a new type of intelligent SOPC based on a permanent magnet vacuum circuit breaker control system. FPGA-based NIOS II as the main processor , the more traditional micro-controller with a higher data processing speed and strong expansion capability to effectively meet the electricity system fast data processing capability and high real-time requirements . And with a powerful FPGA logic functions to achieve internal switch control section and the hardware of the control program , than the direct control of the processor using software implemented with higher reliability and noise immunity . The intelligent control system hardware to EP2C35F672C6 core processor,mainly for failure to protect the real-time data acquisition and processing and circuit breakers,real-time display of current or fault line running information, the intelligent controller to achieve two-way communication with the PC function , via the bus system to reach remote remote adjustment, the purpose of the remote control , making the performance of intelligent controller is enhanced to meet the requirements of the distribution system , which provides protection for the safe operation of power system reliability .
