Load identification and multi-sensor fusion sensing method and device

Abstract

The invention discloses a load identification and multi-sensor fusion sensing method and device, and belongs to the technical field of power monitoring, and the method comprises a power monitoring unit which is used for installing one or more intelligent sensors on an existing power grid to carry out the monitoring and collection of current and voltage; information processing: processing the acquired information by using algorithms of different theories; in the sensing fusion process, complete information about electric power is obtained by using a plurality of sensors, and the survival ability of an electric power system is enhanced in the aspects of detection, tracking and electric power identification by using a multi-sensor data fusion technology. Through reasonable control and use of multiple sensors and observation information thereof, redundant or complementary information of the multiple sensors in space or time is combined according to a certain criterion so as to obtain consistent explanation or description of a tested object, data is processed based on NILM, decomposition and analysis of a power grid can be realized, and the reliability of the power grid is improved. And the limitation when load identification is carried out by using the load steady state characteristic information can be overcome to a certain extent.
