Abstract
A control system and method for a power supply system. The control system includes a front controller and a front voltage conversion circuit and a post controller and a post voltage conversion circuit. The front voltage conversion apparatus is configured to supply power to the post voltage conversion apparatus through a direct current bus. The post voltage conversion apparatus is configured to: receive electric energy transmitted by the front voltage conversion apparatus through the direct current bus, and supply power to a power grid. The post controller is further configured to transmit, to the front controller through the direct current bus, information indicating that high voltage ride-through occurs on the power grid. Voltage control on the direct current bus does not need to depend on the high-speed communication cable, thereby improving control efficiency of a power supply system.
