Disturbance voltage maximum amplitude quantification method and device of in-situ intelligent measurement equipment

Abstract

The invention discloses a disturbance voltage maximum amplitude quantification method and device of in-situ intelligent measurement equipment. The disturbance voltage maximum amplitude quantification method of the local intelligent measurement equipment comprises the following steps: extracting an inter-fracture breakdown voltage and an nth micropulse amplitude of a port disturbance voltage of nth breakdown of a VFTO in the same disconnecting switch operation process; forming an event pair by the extracted breakdown voltage between the fractures and the micro-pulse amplitude so as to form a sample set of a quantile regression model; and training a quantile regression model based on the sample set to generate a corresponding quantile regression equation, the generated quantile regression equation being capable of quantitatively evaluating the port disturbance voltage amplitude of the in-situ intelligent measurement device under the operation of the isolation switch. Therefore, the disturbance level of the on-site intelligent measurement equipment port of the specific GIS test loop under the operation of the isolating switch can be quantitatively evaluated, and a targeted immunity test assessment scheme is formulated.
