Title:

HIGH VOLTAGE SWITCH CONTROL SYSTEM AND METHOD FOR WIND TURBINE

Document Type and Number:

WIPO Patent Application WO/2021/082459

Kind Code:

A1

Abstract:

A high voltage switch (K1) control system and method for a wind turbine, relating to the field of wind power generation. One end of a high voltage switch (K1) is connected to a transformer of a wind turbine, and the other end is connected to a high voltage bus. The high voltage switch control system for a wind turbine comprises: an uninterruptible power supply activation device (11), configured to send an activation instruction to an uninterruptible power supply (12) of the wind turbine in the case that the high voltage bus is energized; the uninterruptible power supply (12), configured to supply power for a high voltage switch control device (13) in response to the activation instruction; and the high voltage switch control device (13), configured to control the high voltage switch (K1) to close in response to a remote closing instruction of the wind turbine. This technical solution can achieve remote closing and improve the timeliness of closing.
