摘要

分析了变电站高压设备变压器、断路器、互感器和电容型设备的在线监测技术与功能,提出基于无线传感网络的变电站设备在线监测方案,据此完成了基于ZigBee技术的分布式在线智能监测系统的总体方案和软硬件设计.结果表明,该系统将传感器和控制器连接到ZigBee网络中的节点上,实现了传感器和控制器的无布线的散列摆放,用户无需重新布线,就能轻松实现对一次设备状态信息的多种智能控制,可方便地为智能变电站提供实时信息.%This paper analyzes the on -line monitoring technology for the high voltage equipment of the power substation including power transformers, circuit breakers, transducers and capacitive equipment and its functions, and proposes the scheme of an on-line monitoring system based on WSN. The overall design with both software and hardware of the system is designed on ZigBee. As a result, the system can connect the sensor and controller onto the ZigBee node in the network and realize the scattering display without wire-layout of the sensor and controller, and the users can easily realize multiple smart controls of the condition information of the primary equipment and conveniently provide the real梩ime data for the smart substation.
