Embodiment Construction

[0030] The non-intrusive online load decomposition device of the present invention includes a data acquisition module, a load decomposition module, a communication module, a display module, and an interactive interface module. The structure of each module is as follows figure 1 As shown, each module adopts a modular package. The data acquisition module collects real-time voltage and current information from the indoor 220V bus, and converts the collected information into digital signals through the A / D converter, and transmits them through the USB communication cable. When it meets the decomposition enzyme, the load decomposition module performs real-time calculation and analysis to realize the online decomposition of the load. The data acquisition module includes a voltage and current transmission board and a data acquisition board. The voltage and current transmission board is used to set the 220V bus at the user's power entrance. The voltage and current transmission board ...

Abstract

The invention relates to a non-invasive online load decomposition device, and belongs to the technical field of load decomposition of a power system. The load decomposition device provided by the invention comprises a data collection module, a load decomposition module, a communication module and an interaction interface module, wherein various modules are packaged in a modular manner; an output end of the data collection module is connected with the load decomposition module; and the load decomposition module is used for communicating with a data terminal of an electric power company through the interaction interface module, and is used for transmitting electricity information of a user to the electric power company, simultaneously receiving the latest updated electricity information database pushed by power, updating a local database conforming to the decomposition module and improving the recognition accuracy on an electrical appliance with the latest model. The non-invasive online load decomposition device is conducive to further understanding of the composition of a user load by the electric power company and strengthening of load side management; and meanwhile, the non-invasive online load decomposition device is conducive to penetrating and refining power monitoring into main electric equipment in the load, so that relatively accurate data are provided for simulation analysis and systematic planning of the power system.

Description

technical field [0001] The invention relates to a non-invasive online load splitting device, which belongs to the technical field of load splitting in electric power systems. Background technique [0002] For power systems, power consumption monitoring is the basis for energy conservation. However, traditional load monitoring generally requires hardware devices such as sensors to be installed outside each monitored electrical device, which not only requires a large amount of capital investment, but also costs a lot of money and time during the installation and maintenance stages, and these "intrusive" The design method of the technology requires short-term power outages for power supply users during installation and maintenance, which may easily cause user dissatisfaction or other economic losses, and it is often difficult to meet the needs of system optimization, energy saving, fault detection and analysis, etc. Contents of the invention [0003] The purpose of the prese...
