Problems solved by technology

[0003] For factory enterprises, they will arrange some electrical appliances with the same function in the factory building, and often hope that the overall working conditions of these electrical appliances can meet the requirements, and do not make specific requirements for the use of individual electrical appliances. In this case , if the method of reducing the power of all electrical appliances is still used, it may be due to the non-linear situation of the energy consumption rate and utility of the electrical appliances, resulting in the reduction of energy consumption, but the corresponding utility is rapidly reduced in a non-proportional and unpredictable form Case

Abstract

The invention discloses an electric appliance power control method, which comprises the following steps of: according to a historical power supply network access condition of a preset electric appliance, estimating that the whole accessed electric appliance is listed as an observation group; carrying out packet loss probability judgment on the electric appliances in the observation group, estimating the power consumption of the electric appliances in the observation group, and determining the electric appliances of which the power needs to be reduced; reducing the power of the applied electric appliance according to the condition of the actually connected electric appliance; detecting the approach degree of the statistical average power consumption of the electric appliances actually connected to the power supply network relative to the preset bearing power; determining a polling period according to the approaching degree; randomly acquiring an actual unit time accumulated energy consumption value of one of the electric appliances actually connected to the power supply network each time; and judging whether the obtained numerical value is greater than the reduced power value or not, if so, giving an alarm, and adaptively cutting off the access of the application electric appliance to the power supply network.

Description

technical field [0001] The invention relates to the field of electric energy meter control, in particular to a method and device for controlling the power of electrical appliances. Background technique [0002] With the development of society, the number and scale of electrical appliances connected to the power supply network are increasing. Especially in factory areas, certain electricity consumption indicators are allocated to specific enterprises every year. These indicators are usually refined to different time periods. For example, during different time periods during the day and night, there will be a certain limit on the total power of electrical appliances that are allowed to be connected. If this limit is broken, it may bring certain impacts, such as increasing the burden on the power grid. Correspondingly, due to Due to the impact of tiered electricity prices, enterprises also need to pay more electricity costs. Usually, enterprises will choose to uniformly reduce...
