Document Type and Number:
WIPO Patent Application WO/2024/080415
Kind Code:
A1
Abstract:
The present invention relates to a method for determining the type of partial discharge of a live-line high-voltage stator winding by applying a support vector machine technique to a PRPD pattern image, in which a partial discharge pattern generated in a motor of a power plant, etc. is automatically analyzed to enable determination of the type of partial discharge. In order to solve the above problem, the method for determining the type of partial discharge of a live-line high-voltage stator winding by applying a support vector machine technique to a PRPD pattern image, according to the present invention, comprises: a partial discharge signal detection step; a signal processing step; a partial discharge pattern generation step; a data processing step; a multi-class support vector machine application step; a risk diagnosis step; and an output step.
