摘要
为了提高多通信信道监测精度,实时监测线损异常,提出配电网分线线损异常多通信信道实时监测方法。根据配电网及其通信结构特征,构建通信信道模型。在该模型下,在各个分线上选择监测点位置,并安装实时监测设备;利用安装的硬件设备采集多通信信道实时数据,并计算理论线损值和实际统计线损值;通过对比理论值与实际值,判断分线线损是否异常,从而得出多通信信道的实时监测结果。实验结果证明:设计监测方法得出的结果十分接近设置的真实结果,即监测精度高;设计监测方法的通信信道平均线损率为46.61%,即应用性能优。设计方法能够实时监测线损异常,综合提高了线损的检测性能,降低了信道线损率。
In order to improve the monitoring accuracy of multi-communication channel and real-time line loss,a real-time monitoring method of multi-communication channel is proposed.The communication channel model is constructed according to the distribution network and its communication structure characteristics.Under this model,the monitoring point is selected on each branch and the real-time monitoring equipment is installed and the theoretical line loss value are calculated.By comparing the theoretical value and the line loss is abnormal with the actual value,the real-time monitoring result of the multi-communication channel is obtained.The experimental results prove that the results of the design monitoring method are very close to the real result,i.e.,it has a high monitoring accuracy;the average communication channel loss rate of the design monitoring method is 46.61%,namely the excellent application performance.The design method can monitor line loss abnormality in real time,improve the detection performance of line loss and reduce the channel line loss rate.
