With the advancement of the intelligent construction of the power system,the type,quantity,complexity,and failure rate of internal electrical equipment have increased,posing a significant challenge to the stable operation of the power system.In or-der to ensure the safe operation of electrical equipment,a method for detecting abnormal operating conditions of electrical equipment based on PLC and configuration technology is proposed.Introducing PLC and configuration technology to design a monitoring architec-ture for the operating status of electrical equipment,collecting and transmitting operating data of electrical equipment,and based on this,through the wavelet denoising method and the de-DC algorithm,the denoising method is optimized to pre-process the signal da-ta of the operating state of the electrical equipment,extract the features of the pre-processed signal data,obtain the comprehensive features by weight,and construct the abnormal operating state detection function of the electrical equipment to detect the abnormal op-erating state of the electrical equipment.Experimental data show that after the application of the proposed method,the maximum in-tegrity value of electrical equipment operation data collection is 92％,and the proportion of abnormal operating electrical equipment is consistent with the corresponding value of the set experimental conditions,fully confirming that the proposed method has better appli-cation performance.
