Sag monitoring system based on improved dip angle measurement

为了提高动态增容的安全性,有必要对输电线路弧垂进行实时监测,为此需构建导线的弧垂监测系统。通过建立导线倾角—弧垂的数学模型,分析弧垂计算过程中误差产生的原因,提出改进措施,并通过实验验证了改进措施对提高弧垂计算精度的有效性。同时设计了基于Zigbee技术与GPRS相结合的无线传输网络,具有扩展性强,功耗低的特点。构建了无线传感网络供电模块,使整个弧垂监测系统能够准确、可靠、实时地工作。

In order to improve the security of dynamic capacity-increase, it is necessary to carry out real-time monitoring for transmission line sag, so the construction of transmission line sag monitoring system is needed. By establishing the mathematical model of dip angle-sag, this pa- per analyzed the causes of sag calculating process errors, proposed the improvement meas- ures, and the effectiveness of the improvement measures for raising the sag calculation accura- cy was verified by the experiment. At the same time, the wireless transmission network was designed based on Zigbee technology combined with GPRS, it has the characteristics of strong extensibility and low power consumption. Constructing the power supply module for wireless sensor network made the whole sag monitoring system work accurately, reliably and in real time.
