Compressor control method, compressor and electrical equipment

Abstract

The invention discloses a compressor control method, the compressor and electrical equipment. The compressor control method includes the following steps: receiving a power-on signal for recovery from power-off; obtaining a random number and processing it according to the power-on signal It is a random number variable, and the random number variable is used to determine the delayed start time of the compressor; according to the delayed start time, the compressor is controlled to perform a compressor start operation after the delayed start time arrives. The present invention determines the delayed start-up time of the compressor by using the generated random number variable, and performs the compressor start-up operation after the delayed start-up time is reached, so that the start-up time of the compressor becomes random and not fixed. After the electric area or household users recover from power failure, when the compressors of multiple electrical equipment with power failure recovery function are started, it can prevent multiple compressors from starting at the same time, reduce the current impact on the power grid, and improve the stability of the power grid.

Description

technical field [0001] The invention relates to the field of electrical equipment, in particular to a compressor control method, the compressor and electrical equipment. Background technique [0002] At present, most electrical equipment has a power-off recovery function, so as to ensure that the electrical equipment can run for a long time according to the set function, and avoid affecting the user experience due to power grid fluctuations and supply suspensions. For air conditioners, refrigerators and other products due to the start-up characteristics of the compressor, from stop to normal operation, the current produced is several times the normal operating current (generally 2 to 12 times), and the required start-up time is very short (generally 0.02 to 0.8 seconds, each model of compressor and usage are different). When the power supply is restored after the power supply grid is cut off, the compressors of multiple electrical equipment with power failure recovery funct...

AI Technical Summary

Problems solved by technology

[0003] The main purpose of the present invention is to provide a control method for a compressor, a compressor and electrical equipment, aiming at solving the problem of the simultaneous failure of compressors of multiple electrical equipment with a power-off recovery function in the same power-consuming area or after a household user recovers from a power-off recovery. Start-up produces a large current impact on the power grid, which is likely to cause voltage and current fluctuations in the power grid and affect the stability of the power grid
