针对目前分界开关控制器智能化程度不高、数据采集精度不足的情况,设计一种智能控制器系统。采用模块化设计,以ARM微处理器为核心,对配电线路电压、电流及开关状态信息进行检测,检测数据通过无线模块上传给监控中心,实时监测配电线路运行状态和开关状态。分别对电流和电压信号进行测试,测量值和计算值的相关系数分别为0.996 1和0.996 8,均满足控制器精度设计要求误差在±0.5%额定值,为电力系统配电线路分界开关智能控制器的研究提供基础。

In this paper, an intelligent controller system is designed to overcome low intelligence degree and the lack of dataacquisition accuracy for the current interface switch controller. Through the modular design method, the ARM microprocessor isemployed as the core part for detecting distribution line voltage, current and switch status information in the intelligent controllersystem. Then, the test data can be uploaded to the monitoring center through wireless module. The operating state of distribution lineand 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 measuredand the calculated voltage is 0.9968. The results show that the presented controller system can satisfy the requirements of errorcontrol （±0.5%）. This paper provides a basis for research on intelligent controller in power system distribution circuit.
