Title:
DRIVING CONTROL DEVICE AND METHOD FOR YAW ELECTRMOTOR OF WIND POWER GENERATION SET
Document Type and Number:
WIPO Patent Application WO/2018/107721
Kind Code:
A1
Abstract:
A driving control device and method for the yaw electromotors of a wind power generation set. The driving control device (400) comprises a frequency converter (410), a fault cut-out contactor (420), and a contactor (430); the frequency converter is used for performing driving control on yaw electromotors (M1, M2); the fault cut-out contactor is connected in series between the frequency converter and the yaw electromotors and is used for disconnecting when a fault has occurred in the frequency converter so as to isolate the frequency converter in which the fault has occurred; and the contactor is connected in parallel with the frequency converter and the fault cut-out contactor, and is also connected with the yaw electromotors to further drive the yaw electromotors after the fault cut-out contactor is disconnected. Problem of low reliability of driving control on the yaw electromotors can be solved by using the driving control device and method.
