Automatic Monitoring Method of Transmission Line Transformer Operation Status Based on Optical Fiber Communication
Aiming at the problem of unsatisfactory monitoring results of current transmission line transformers,a method for automatic monitoring of the operation status of transmission line transformers based on fiber optic communication is proposed.This method first uses fiber optic communication technology to measure the temperature of the transformer winding and obtain the temperature signal of the transformer winding.Then,the wavelet denoising method is used to filter and process the obtained winding temperature signal.Finally,the abnormal operating status of the transformer is identified by comparing the upper limit of the winding temperature,and early warning and monitoring of the abnormal status are carried out.Experimental results have shown that the abnormal state recognition rate of the design method is not less than 98%,and it can achieve accurate monitoring of the operating status of transmission line transformers,with good application effects.
