Smart home control system and method based on power line carrier communication

Abstract

The invention provides a smart home control system and method based on power line carrier communication, and the system comprises a transformer area broadband carrier concentrator which is used for receiving a cloud operation platform instruction and transmitting a first carrier signal to a master controller; the master controller is arranged in the electric meter box, is connected with the home-entry bus, receives the first carrier signal and sends a second carrier signal to the load controller; and the load controller is provided with a relay, and when the second carrier signal is received, the relay is controlled to work to cut off the power supply of the load. Through carrier communication, the state grid management end can uniformly regulate and control the loads of the users who voluntarily participate in grid peak clipping, and grid peak clipping on the low-voltage side is achieved.

Description

technical field [0001] The invention relates to the technical field of carrier communication, in particular to a smart home control system and method based on power carrier communication. Background technique [0002] Load transfer management is the main work content of power marketing. Its purpose is to promote balanced power consumption, increase the load rate of the power grid, improve the economic operation of the power grid, optimize the allocation and rational use of power resources by changing the time and mode of power consumption, and at the same time enable customers to benefit from it. benefit. [0003] Due to the diversity and uncertainty of power demand, the power generation and power supply capacity set to meet the maximum demand of customers is largely idled during low demand periods, which not only increases the cost of power generation and power supply, but also increases the burden of electricity charges on customers. In order to change this situation, ele...

Problems solved by technology

The peak outage of large-scale electrical equipment is a load control strategy on the high-voltage side. On the low-voltage side, such as the electricity consumption of each household and shopping malls, there is no good regulation method. China has a large population, and basically every day Every household is connected to electricity, and the number of electrical equipment in each household also increases. The power consumption on the low-voltage side increases, the peak value of the grid increases, and the peak time increases. However, some of the equipment does not need to be turned on for a long time and can be turned off during the peak period. In order to achieve the purpose of peak shaving, each household reduces power consumption by 1 watt, and 1 million households can reduce 1 million watts. The peak shaving is obvious. However, the existing technology lacks a unified control device for the low-voltage side, and cannot well realize the power grid peak. peak clipping
