METHOD FOR DETECTING PARTIAL DISCHARGE OF GAS INSULATION SWITCHGEAR BY USING METHOD FOR DECOMPOSING UNIQUE VALUE FROM ATTRACTOR USED IN CHAOS THEORY

摘要

PURPOSE: A method for detecting a partial discharge of a gas insulation switchgear by using a method for decomposing the unique value from an attractor used in a chaos theory is provided to apply an algorism easily realized in the hardware. CONSTITUTION: A method for detecting a partial discharge of a gas insulation switchgear by using a method for decomposing the unique value from an attractor used in a chaos theory includes the steps of: a first step(S2) of removing and normalizing the noise for the partial discharge; a second step(S3) of converting into a surrogate data so as to have a non-linear characteristics by mixing the internal structure with maintaining the linear characteristics; a third step(S3) of reconstructing the attractor to geometrically analyzing the data by using a differential after the time delay and the buried dimension are determined by the surrogate data; a fourth step(S5) of calculating the distribution of the orthogonal axis by using the unique value in the attractor reconstruction and determining the status of the gas insulation switchgear among a normal, alarm and failure.
