Detection Method for Insulation Dielectric Loss Sensing Signals of Electrical Equipment Based on Singular Value Decomposition Algorithm
Aiming at the difficulty in analyzing the fluctuation characteristics of signals and ignoring the influence of dual signal noise,which leads to a large deviation in the insulation dielectric loss factor of the detection results,a detection method for electrical equipment insulation dielectric loss sensing signals based on singular value decomposition algorithm is proposed.Construct a temporal feature window to smooth the original sensing signal,analyze the pulse and Gaussian dual noise of the processed sensing signal,separate and reconstruct the corresponding noise values,introduce singular value decomposition algorithm to decompose the insulation medium current sensing signal,and analyze the morphological wave of the decomposed signal to calculate the detection result of the insulation medium loss sensing signal.The experimental results show that the detection results obtained by the proposed method have a small deviation in insulation dielectric loss factor and high detection accuracy,which meets the practical needs of electrical equipment insulation performance operation and maintenance.
