高压输电线在风激励作用下发生的震荡运动尤其覆冰舞动是影响电网安全的重要因素,针对当前加速度传感器舞动监测装置存在供电难、多点监测同步性差、全天实时回传数据量大且后期数据保存及提取工作量较大等问题,本文设计了一种可编程低功耗高压输电线舞动监测系统。系统利用FPGA参数可编程控制技术,实现双重选择下的智能重点监测,并通过ZigBee无线网络传输控制信号和测试数据。实验表明该系统能可靠监测高压输电线舞动信号,还具有操作简单灵活、低成本的特点,性能可以满足高压输电线舞动的需求,具有良好应用前景。

The oscillating motion of high voltage transmission lines under the action of wind excitation,especially the ice-shaking movement,is an important factor affecting the safety of the power grid. For the current acceleration sensor galloping monitoring device,there is difficulty in power supply,poor synchronization of multi-point monitoring,and large amount of real time data transmission throughout the day. In the later stage,the data storage and extraction workload is large. This paper designs a programmable low power high voltage transmission line dancing monitoring system. The system utilizes FPGA parameter programmable control technology to realize intelligent key monitoring under dual selection,and transmits control signals and test data through ZigBee wireless network. Experiments show that the system can reliably monitor the galloping signal of high-voltage transmission lines,and it has the characteristics of simple,flexible and low cost operation. The performance can meet the needs of high voltage transmission line galloping and has a good application prospect.
