Abstract

The invention discloses a power consumption monitoring system and method based on non-invasive monitoring technology. The system includes a data acquisition device, a background analysis master station and a client terminal on the user side. The data acquisition device is responsible for collecting, preprocessing and transmitting user-side current data; the background analysis master station stores the harmonic analysis results of each electrical equipment during normal operation and the equipment switch status of each user, and analyzes the data through the stored equipment harmonics. As well as historical equipment working status data, the cloud genetic algorithm is used to identify the equipment switch status on the received bus current waveform information, and the result is sent to the client. The present invention can realize the recognition of the switching state of the user equipment based on the electrical data collected at the main incoming line of the power user, without intruding into the user's interior to install a large number of sensors, with little impact on the user's production and life, low economic cost, and strong practicability , Widely applicable to commercial, residential and industrial users.

Description

technical field [0001] The invention relates to the monitoring and management of a power distribution system, in particular to a power monitoring system and method based on a non-invasive monitoring technology. Background technique [0002] As the development direction of the power system, the smart grid refers to a strong grid based on the UHV grid as the backbone grid and coordinated development of grids at all levels, supported by a communication information platform, with the characteristics of informatization, automation, and interaction, and realizing " A modern power grid with a high degree of integration of power flow, information flow, and business flow can well accommodate distributed clean energy, improve the utilization rate of electric energy through demand-side management, and achieve the goal of energy conservation and emission reduction. Data analysis technology is a necessary condition for the smart grid to achieve high informatization and automation. Using ...
