The invention provides an output inductance value control method and device of a multi-tap reactor and computer equipment. A single output port of the multi-tap reactor is correspondingly connected with a single relay, and each relay is communicated with a main power supply of all air conditioner internal units. During use, the air conditioning system obtains a motor rotating speed and a phase current of each air conditioner indoor unit, and then the motor power sum of all the air conditioner indoor units is obtained through calculation according to the motor rotating speed and the phase current. The system matches the basic inductance required by the air conditioner indoor unit according to the sum of the motor power, sets the current output inductance of the multi-tap reactor according to the basic inductance, and inputs the output inductance into the corresponding air conditioner indoor unit, thereby reducing the harmonic component generated by the corresponding air conditioner indoor unit during operation. In the output inductance value control method and the device, the air conditioning system dynamically adjusts the inductance value output by the multi-tap reactor according to the real-time power of all the air conditioning indoor units, so that the harmonic component generated during the operation of the air conditioner can be effectively reduced, and the applicability is relatively high.
Description
technical field [0001] The present application relates to the technical field of air conditioners, in particular to a method, device and computer equipment for controlling the output inductance of a multi-tap reactor. Background technique [0002] During the operation of the air conditioner, the AC input current will produce serious waveform distortion and inject a large number of high-order harmonics into the power grid. In order to reduce the current harmonic component and improve the power factor, existing manufacturers will connect a reactor in series with the AC input end inside each air conditioner. When an air conditioner contains multiple internal units, each internal unit needs to add a reactor, which will cause the production cost of the air conditioner to be too high; and the inductance of a single reactor is fixed and cannot be adjusted accordingly. Applicability is low. Contents of the invention [0003] The main purpose of this application is to provide a m...
