Research on microcomputer interferon source location technology for commissioning of 10kV Substation and distribution station

Abstract:
The traditional microcomputer interference source localization technology in the debugging field of the substation neglects the de-noising processing of the interference source and cannot obtain the transmission path of the electromagnetic interference signal. In order to improve the effect of signal preprocessing and the accuracy of interference source location, a microcomputer interference source location technology was proposed in the debugging field of 10kV substation. The interference electromagnetic signals are extracted from the mixed electromagnetic signals by singular value decomposition (SVD), and the noise interference is reduced by truncated SVD. After analyzing the electromagnetic signal transmission path after denoising, the distance between the interference source and the signal breakpoint and the distance between the signal position recapture and the interference source are obtained, the signal position loss point and the signal position recapture point in a certain area are determined, and the specific position of the interference source is located. The experimental results verify that the proposed technology can eliminate the noise signal of the interference source information during data preprocessing and improve the accuracy of the interference source location effectively.
