Abstract
The purpose of separating transformer winding signal and the vibration signal of iron core is to monitor their operation status, so in this paper, the vibration signal of transformer iron core and winding is separated from hybrid signals monitored by sensor based on independent component analysisC ICA) theory and Joint Approximate Diagonal-ization of Eigen-matrices(JADE) algorithm. Then the frequency characteristics of vibration signal of each element are compared and analyzed with original signals from database, which can judge the hidden faults of transformer. The JADE algorithm is realized by combing Lab VIEW and MATLAB. Simulation results show that JADE algorithm can be used to separate source signals from monitored signals and source signals under unknown signal source and hybrid parameters.关键词
