Abstract: In this paper, an intelligent controller system is designed to overcome low intelligence degree and the lack of data acquisition accuracy for the current interface switch controller. Through the modular design method, the ARM microprocessor is employed as the core part for detecting distribution line voltage, current and switch status information in the intelligent controller system. Then, the test data can be uploaded to the monitoring center through wireless module. The operating state of distribution line and switching status can be monitored in real time. The voltage and the current are measured using the intelligent controller system. The correlation coefficient of the measured and the calculated of current is 0.9961, and the correlation coefficient of the measured and the calculated voltage is 0.9968. The results show that the presented controller system can satisfy the requirements of error control (±0.5%). This paper provides a basis for research on intelligent controller in power system distribution circuit.
