Abstract

The invention discloses a multi-module parallel control method and system. The multi-module parallel control method comprises the steps that a power supply main module is enabled to be in parallel connection with multiple power supply slave modules by adopting a communication connection mode; the power supply main module carries out sampling on voltage and current parameters of the system and obtains the output power required by a load after calculation, the output power is equally distributed, then the average power should be output by each power supply slave module is broadcast and transmitted to each power supply slave module through a communication bus; and finally, each power supply slave module receives the given power transmitted by the power supply main module and outputs the corresponding power through the control thereof. There is only a power instruction transmitted by the main module to the slave modules in a communication line, and no other interactive information is required, so that the communication speed is high and not affected by the number of parallel modules, and the capacity can be expanded conveniently.

Description

technical field [0001] The invention belongs to the technical field of power supply control, and in particular relates to a multi-module parallel machine control method and system. Background technique [0002] With the development of our country's economy and society, new energy, energy storage, industry, etc. have been developed rapidly, and the power capacity used by them is getting larger and larger. Relying on a single power module can no longer meet the requirements of users. Multi-module parallel control is adopted. Technology can not only increase the capacity of the system, but also greatly improve the reliability of the system, which has a huge advantage in the occasion of large capacity and high reliability. [0003] The existing multi-module parallel connection mostly adopts distributed control mode. Each module collects information of all other modules, controls the output of this module according to the information, and realizes the average distribution of load...
