Abstract

The invention belongs to the technical field of big data monitoring application, and particularly relates to a non-invasive load monitoring method based on big data. The non-invasive load monitoring method based on the big data includes the following steps that (1) power data is remotely collected, a power system is subjected to data monitoring and monitoring controlling, and actually-measured samples of all transient processes are fully collected; (2) a training model of non-invasive load monitoring is built, and distinguishing space is formed; (3) the non-invasive load transient monitoring is actually measured, actually-measured transient processes are distinguished according to the distinguishing space. According to the non-invasive load monitoring method based on the big data, big-datatechnological means are taken, and a large amount of transient-process data is obtained from accumulated mass power load data; according to the reasonable load classification method, suitable characteristic parameters are selected for building high-dimensional characteristic distinguishing space, and the non-invasive load monitoring function can be accurately and rapidly achieved with the dimension descending and classification method in the big-data technological means.
