剩余电流保护器管理系统研发

Research and Development of Residual Current Protective Device Management System

针对基于MSP430F427单片机的剩余电流保护器开发了一套适应智能电网要求的管理系统。该系统通过安装在各个低压电网上的剩余电流动作保护器,自动监测各线路的状态信息。当线路发生过载、短路、缺相、过压、欠压或剩余电流保护器故障跳闸时,剩余电流保护器通过GPRS数据传输单元向管理人员手机和监控计算机发送信息。管理人员通过信息提示判断引起的故障原因和故障地点,以迅速排除故障,保证供电的可靠性和连续性。

A set of management system is devetoped which is adapt to the reqmrements ot smart grid. It is supporting the use of the residual current protector based on MSP430F427 microcontroller. The system can monitor automatically the state information of each line by residual current protector installed in low voltage power grid. When lines emerge overload, short circuit, phase lack, over-voltage, undervohage and tripping operation due to residual current protector problem, the residual current protector will send information to cell phone of management personnel and monitoring computer through Fne GPRS data transmission units. The personnel judge tile reason and place of line fault according to the information and quickly remove the faults to ensure that the power supply reliability and continuity.
