Description

Technical Field

[0001] The utility model relates to the technical field of electric power control, in particular to an intelligent control system for residential electric heating and daily electricity consumption. Background Art

[0002] The intelligent control system for residential electric heating and household electricity consumption is designed to address the limited household electricity load faced during the large-scale promotion of electric heating. According to the "Residential Building Electrical Design Code" JGJ 242-2011, the electricity consumption index for each residential unit is 40W / m2~50W / m2, while the electricity consumption index for electric heating is 80W / m2~100W / m2. If the electricity consumption for household use and electric heating is combined, the electricity consumption index is 120W / m2~150W / m2, which far exceeds the electricity load of each residential unit and the specified range of the electric energy meter, resulting in a contradiction between supply and demand. Utility Model Content

[0003] The utility model aims to provide an intelligent control system for residential electric heating and domestic electricity consumption which can effectively alleviate the contradiction between supply and demand, balance the load and protect the power grid.

[0004] The utility model is achieved in this way:

[0005] An intelligent control system for residential electric heating and domestic electricity consumption includes a power quantitative controller connected to a main switch in a household distribution box, wherein the power quantitative controller is connected to a domestic electricity branch and an electric heating electricity branch, wherein the electric heating electricity branch is connected to a plurality of interrupting switches, and the interrupting switches are communicatively connected to the power quantitative controller.

[0006] Furthermore, the interrupter switch is connected to the power quantitative controller via a communication module or a power carrier module.

[0007] Furthermore, the interrupter switch adopts a thermostat.

[0008] Compared with the prior art, the beneficial effects of the utility model are:

[0009] In actual applications, during peak electricity consumption periods, the power quantitative controller collects the power load of the domestic electricity branch and the electric heating branch. When the power load of the domestic electricity branch and the electric heating branch exceeds the set threshold, the power quantitative controller controls the interrupt switch to disconnect the corresponding electric heating branch, stop the electric heating power supply and maintain the power supply of the domestic electricity branch to ensure the domestic electricity demand. By utilizing the interruptible load characteristic of electric heating, the electric heating power load is interrupted during the peak period of domestic electricity consumption, and intelligent allocation between the various electric heating circuits and between heating electricity and domestic electricity is achieved, thereby reducing the power capacity. The utility model effectively alleviates the contradiction between supply and demand, balances the load, and protects the power grid. BRIEF DESCRIPTION OF THE DRAWINGS
