Title:
BIDIRECTIONAL CONVERTER-BASED FORSMARK EFFECT SUPPRESSION METHOD AND APPARATUS
Document Type and Number:
WIPO Patent Application WO/2021/196627
Kind Code:
A1
Abstract:
A bidirectional converter-based Forsmark effect suppression method and apparatus. A bidirectional converter is connected in parallel to a rectifier module in an electrical device, and the rectifier module is used for converting an alternating current inputted to the electrical device into a direct current, and outputting same to a direct current bus of the electrical device. Said method comprises: monitoring the voltage of a direct current bus of an electrical device (101); and if it is monitored that the voltage of the direct current bus is greater than a preset voltage threshold, controlling a bidirectional converter to enter a first working mode, wherein in the first working mode, the bidirectional converter is used for feeding the energy of the direct current bus of the electrical device back to an access power grid (102), thereby effectively suppressing the Forsmark effect, and guaranteeing the normal operation of a system.
