摘要
由于输电线路覆盖地域广泛,面临着极为严峻的运行环境挑战,易发生运行故障。基于此,提出基于无线通信网络的输电线路状态监测方法。结合行业标准和专家经验,确定反映线路健康状况的关键状态参数,包括温度、电流、电压、湿度、振动以及局部放电等,并构建无线通信网络架构。该架构由传感器节点、中继节点、汇聚节点以及数据中心组成,通过该架构实时监测输电线路状态参数。采用傅里叶变换方法提取无线通信网络采集的原始数据特征,并构建模式识别模型,以识别正常运行模式和潜在的异常模式,将提取的特征输入训练好的模式识别模型,得到预测结果,基于模式识别模型的预测结果,实现输电线路状态异常检测。实验结果表明,采用设计方法可有效降低输电线路状态监测误差,提高监测准确率,有效保障智能监测效果。
Because the transmission line covers a wide area,it faces extremely severe operational environment challenges and is prone to operational failures.Based on this,a method of power transmission line condition monitoring based on wireless communication network is proposed.Combined with industry standards and experts’experience,the key state parameters reflecting the line health,including temperature,current,voltage,humidity,vibration and partial discharge,are determined,and the wireless communication network architecture is constructed.The architecture consists of sensor nodes,relay nodes,sink nodes and data centers,and the state parameters of transmission lines are monitored in real time through this architecture.Fourier transform is used to extract the features of the original data collected by the wireless communication network,and a pattern recognition model is constructed to identify the normal operation mode and the potential abnormal mode.The extracted features are input into the trained pattern recognition model to obtain the prediction results,and based on the prediction results of the pattern recognition model,the abnormal detection of the transmission line state is realized.The experimental results show that the design method can effectively reduce the monitoring error of transmission line condition,improve the monitoring accuracy and effectively guarantee the intelligent monitoring effect.
