Abstract

The invention provides a multi-module system current sharing control method and device and a terminal device, and the method comprises the steps: obtaining a phase angle reference value and an amplitude reference value of a target electrical module if the target electrical module is the first started electrical module; determining a voltage reference value of the target electrical module accordingto the phase angle reference value and the amplitude reference value, and performing double closed-loop control on the target electrical module based on the voltage reference value of the target electrical module; if the target electrical module is not the first started electrical module, acquiring double closed-loop control data of the started electrical module and a phase angle reference valueand an amplitude reference value of the target electrical module; and determining a voltage reference value of the target electrical module according to the phase angle reference value and the amplitude reference value, and performing double-closed-loop control on the target electrical module based on the double-closed-loop control data and the voltage reference value. According to the multi-module system current sharing control method and apparatus, and the terminal device provided by the invention, current sharing control of multiple modules can be realized.

Description

technical field [0001] The invention belongs to the technical field of electrical control, and more specifically relates to a multi-module system current sharing control method, device and terminal equipment. Background technique [0002] In existing multi-module systems, current sharing occurs only when multiple electrical modules are started at the same time. If the starting time of each electrical module is inconsistent, such as starting successively, the sudden change in the feedback caused by the sudden change will lead to a sudden change in the error amount in each electrical module. Uneven flow occurs. [0003] Therefore, how to realize the current sharing control of the multi-module system has become an urgent problem to be solved by those skilled in the art. Contents of the invention [0004] The purpose of the present invention is to provide a multi-module system current sharing control method, device and terminal equipment, so as to realize the current sharing...
