Development of Communication Manager for Supervisory Control of Load and Leakage Current in Low-Voltage Distribution Network

设计了一种用于低压配网负荷及漏电流监控的通信管理机,通信管理机通过ZigBee无线传感器网络与智能断路器进行数据交换,实时采集和存储智能断路器数据,修改智能断路器运行状态、运行模式和参数,并通过GPRS无线网络与监控主站连接,把智能断路器数据传输给监控主站和接收监控主站命令,实现监控主站与智能断路器间的数据采集、命令转发、数据及状态量存储。实际应用表明,该通信管理机具有扩展性好、可靠性高、实用性强等特点。

This paper designed a communication manager that could be used in the load and leakage current of low-voltage distribution network. Via ZigBee wireless sensor network, the communication manager could not only exchanged data with intelligent circuit breakers, but also acquired and stored intelligent circuit breaker data, so as to modify operation condition, operating mode as well as parameters of intelligent circuit breakers. The data from intelligent circuit breakers could be sent to monitor terminals by the connection between the general packet radio service wireless network and the monitoring primary station to realize functions such as data acquisition, command forwarding, data and status storage. Practical application shows that the communication manager has the features of scalability, high reliability and high practicability etc.
