Problems solved by technology

However, seasonal electricity consumption products such as air conditioners have peak electricity consumption periods from April to October, and electricity consumption will gradually increase from May onwards, but it is normal for air conditioners to increase electricity consumption in summer , if the power consumption of the air conditioner is limited simply according to the power consumption, it will appear that when the air conditioner is in normal use, the power consumption of the air conditioner exceeds the preset threshold and the power consumption of the air conditioner will be limited.
[0003] Therefore, the use of constant power consumption to limit the power consumption of electrical appliances in the prior art is unreasonable and not suitable for some electrical appliances.

Abstract

The invention provides an electric appliance energy-saving control method, device and system. The electric quantity increase rate is used for replacing the original fixed electric consumption, when the electric quantity increase rate exceeds the preset increase rate, the electric consumption of an electric appliance is limited, and when the electric quantity increase rate of the electric appliance does not exceed the preset increase rate, it is shown that the electric consumption of the electric appliance is in a normal range. According to the electric appliance energy-saving control method, device and system, when the electric appliance is in a certain frequent electric consumption season, even if the electric consumption of the electric appliance is increased continuously, normal use of the electric appliance cannot be limited as long as the electric quantity increase rate does not exceed the set limitation, and therefore the electric consumption of the electric appliance is reasonably controlled.

Description

technical field [0001] The invention relates to the technical field of automation, in particular to a method, device and system for energy-saving control of electrical appliances. Background technique [0002] In order to limit the power consumption of electrical appliances, traditional electrical appliances adopt power limitation. When the power consumption of a certain electrical appliance exceeds a preset threshold, the electricity consumption of the electrical appliance is limited. However, seasonal electricity consumption products such as air conditioners have peak electricity consumption periods from April to October, and electricity consumption will gradually increase from May onwards, but it is normal for air conditioners to increase electricity consumption in summer If the power consumption of the air conditioner is limited simply according to the power consumption, it will appear that the power consumption of the air conditioner exceeds the preset threshold and the...
