Cloud platform based non-intruding load monitoring system and identification method

Abstract

The invention discloses a coud platform based non-intruding load monitoring system and identification method. The system comprises a hardware node, a cloud server and an intelligent terminal; the hardware node and the intelligent terminal communicate with the cloud server via a network communication module; the hardware node comprises a power supply management unit, a power metering unit, an optical coupler isolation unit, a digital pulse signal counting unit, a microcontroller and a wireless communication unit; the power supply management unit provides needed electric energy for the hardwarenode; and the power metering unit, the optical coupler isolation unit, the digital pulse signal counting unit, the microcontroller and the wireless communication unit are connected sequentially. According to the system and method, power data of a power load is collected in a non-intruding manner, the operation state of the power load is analyzed by means of the cloud server, the type of the powerload is identified, a user is guided to plan power utilization reasonably, energy saving and emission reduction can be realized, faults are eliminated timely, and the system and method become inevitable trend of development of smart grid.

Description

technical field [0001] The invention belongs to the technical field of electric power system automation, and in particular relates to a non-intrusive load monitoring system and identification method based on a cloud platform. Background technique [0002] Electric energy is one of the most widely used and most important energy sources in modern production and life. In terms of energy measurement, the traditional "one household, one meter" method is for the power department to copy the energy meter and give the electricity consumption of the current month. The disadvantage is that the user cannot know the electricity consumption of a specific appliance in a certain period of time. It can be said that the user's grasp of the dynamic real-time operation information of the load set is still quite lacking. In order to solve this problem, the traditional intrusive monitoring method installs power measurement hardware on each load to be measured, and monitors the load operation in...

Problems solved by technology

The disadvantage is that the original power supply circuit of the load needs to be destroyed, and a lot of manpower and material resources will be spent on installation and maintenance.
