Abstract

The present invention relates to a three-phase four-wire power supply intelligent phase correction method and system, and a three-phase four-wire power supply intelligent phase correction method and system, comprising: S100, obtaining the three-phase voltage values ​​of each safety power supply equipment, and according to the Calculate the voltage value to obtain the corresponding phase value; S200, determine whether the difference between the phase values ​​of the three phases of the safety power supply equipment is within the preset phase threshold and whether the difference between the voltage values ​​is within the preset voltage threshold, and if so, then Perform parallel operation, otherwise go to step S300; S300, correct the three-phase phase values ​​of the safety power supply equipment, and perform parallel operation when the three-phase phase values ​​corresponding to the safety power supply equipment are the same. The present application is used to solve the technical problems that the phases of the three-phase four-wire of the safety power supply equipment cannot be identified and the phases cannot be corrected in the existing system.

Description

technical field [0001] The invention relates to the field of intelligent power supply systems, in particular to a three-phase four-wire power supply intelligent phase correction method and system. Background technique [0002] The safety power supply equipment is generally connected to the AC mains, but the existing safety power supply equipment intelligently provides a voltage output of 36KV. If it is industrial power, a larger voltage is required. Therefore, a single safety power supply equipment cannot meet the demand. Connect the two devices in parallel to output a larger voltage. [0003] However, most of the existing products use pure hardware to realize the parallel detection of two safety power supply devices. In this parallel situation, when the phases or voltages of the two devices are different, they will also be detected. In parallel, it is easy to cause the problem of overheating or burning of the safety power supply equipment; and the existing system cannot co...
