摘要
电网是否具有稳定运行能力成为电力企业研究的热点问题,电网的运行状态取决于电网设备的健康程度。当前使用的电网设备运行稳定性监测方法对于新基建电网设备数据处理能力较差,导致其监测结果的正检率较低且误检率较高。同时,此方法的设备运行状态特征提取及状态分析时间比也说明了当前使用方法效果不佳。因此,设计面向新基建的电网设备运行稳定性监测方法。使用快速傅里叶变换技术对设备数据采集过程进行控制,提升数据采集精度。使用双峰谱线修正算法对采集到的数据进行校正,确保此数据具有分析价值。选择红外线仪器获取电网设备运行数据,并使用上述数据处理方法进行分析,将分析后数据传入原有方法的状态识别模块中,完成设备运行状态的划分。至此,面向新基建的电网设备运行稳定性监测方法设计完成。构建仿真实验环节,将此方法与目前使用方法进行对比可知,此方法的监测结果正检率以及误检率均得到了提升。综上可知,此方法在使用中具有有效性与科学性。
Whether the power grid has the ability of stable operation has become a hot issue for power enterprises.The operation state of the power grid depends on the health of the power grid equipment.The current monitoring methods of power grid equipment operation stability have poor data processing ability for new infrastructure power grid equipment, which leads to low positive detection rate and high false detection rate of monitoring results.At the same time, the time ratio of feature extraction and state analysis also shows that the current method is not effective.Therefore, it is necessary to design a new monitoring method for the operation stability of power grid equipment.Fast Fourier transform technology is used to control the data acquisition process and improve the accuracy of data acquisition.The bimodal spectral line correction algorithm is used to correct the collected data to ensure that the data has analytical value.The infrared instrument is selected to obtain the operation data of power grid equipment, and the above data processing method is used for analysis.The analyzed data is transferred into the status identification module of the original method to complete the division of equipment operation status.So far, the design of power grid equipment operation stability monitoring method for new infrastructure is completed.Compared with the current methods, the positive detection rate and false detection rate of the monitoring results of this method have been improved.In conclusion, this method is effective and scientific in use.
