【摘要】：针对目前高压变配电站中电气设备众多,数据传输难度大以及缺乏有效的绝缘在线监测方法等问题,研发新型局部放电无线监测系统。设计系统的整体硬件架构,并提出基于Zigbee协议的无线传输方案和超声波无线传感器设计方案,实现数据的实时采集、传输和处理功能;搭建在线监测平台,开发数据滤波技术、数据库存储技术以及准确可靠的告警算法。变电站实际安装测试表明,该系统能够有效地监测电气设备的局部放电情况,并及时准确地告警,有助于保证变配电站的稳定可靠运行。
[Abstract]:At present, there are many electrical equipments in high voltage transformer and distribution station, it is difficult to transmit data and lack of effective on-line insulation monitoring method. A new PD wireless monitoring system is developed. The overall hardware architecture of the system is designed, and the wireless transmission scheme based on Zigbee protocol and the design scheme of ultrasonic wireless sensor are proposed. The function of real-time data acquisition, transmission and processing is realized. Build online monitoring platform, develop data filtering technology, database storage technology and accurate and reliable alarm algorithm. The actual substation installation test shows. The system can effectively monitor the partial discharge of electrical equipment and alarm timely and accurately, which is helpful to ensure the stable and reliable operation of substation.
