摘要

Existing UHF partial discharge (PD) localization technology is mainly based on time delay algorithm which has expensive hardware cost and is hard to achieve. This paper proposed a compressed sensing based PD localization methodology which was based on received signal strength indicator (RSSI) fingerprinting localization algorithm. It has easy fulfilling features and good environmental adaptability. Firstly, the RSSI fingerprinting was built in the offline stage. Secondly, in the online stage, BP neural networks is used to achieve preliminary localization, then compressed sensing strategy is deployed to achieve more accurate localization. The filed test showed that the mean errors of PD localization by out proposed method is 0.2 m and 93.9% of errors is smaller than 1 meter. The test proved that proposed localization algorithm is accurate and has good practical value.
