供配电系统继电保护整定数据异常识别方法

Abnormal Identification Method of Relay Protection Setting Data in Power Supply and Distribution System

由于现行方法在供配电系统继电保护整定数据异常识别中的应用效果不佳,错识率与漏识率较高,识别精度较低,无法达到预期的识别效果,提出供配电系统继电保护整定数据异常识别方法。利用无线传感技术采集继电保护整定数据,并对缺失数据进行插补处理,通过映射分析预处理后的数据,提取整定数据的异常特征。根据异常特征对整定数据进行异常评分,识别异常整定数据,以此完成供配电系统继电保护整定数据的异常识别。经实验证明,设计方法的错识率与漏识率均在1%以内,在供配电系统继电保护整定数据异常识别方面具有良好的应用前景。

Due to the poor application effect of the current method in the abnormal identification of the relay protection setting data of power supply and distribution system,the error rate and missing rate are relatively high,and the recognition accuracy is relatively low,which cannot achieve the expected recognition effect.Therefore,this paper puts forward the abnormal identification method of the relay protection setting data of power supply and distribution system,the wireless sensor technology is used to collect the relay protection setting data and interpolate the missing data,through the mapping analysis of the pre-processed data,the abnormal characteristics of the setting data are extracted.According to the abnormal characteristics of the setting data,the abnormal setting data is identified,so as to complete the abnormal identification of the relay protection setting data of the power supply and distribution system.The experimental results show that the error rate and missing rate of the design method are both within 1%,which has a good application prospect in the abnormal recognition of relay protection setting data in power supply and distribution system.
