Title:
TIP REGULATION CONTROL METHOD FOR INCREASING MINIMUM CLEARANCE FOR LARGE-SCALE WIND POWERED POWER-GENERATION UNIT
Document Type and Number:
WIPO Patent Application WO/2015/196739
Kind Code:
A1
Abstract:
Disclosed is a tip regulation control method for increasing minimum clearance for a large-scale wind powered power-generation unit. On the basis of traditional control strategies, a power tip regulation is added, and when the power reaches a certain limit, pitch varying is started in advance, thrust is reduced and minimum clearance is increased. The method control is simple and highly efficient, the effect of minimum clearance increase is marked, loss of generated electricity is very low, and the unit overrun and stopping due to a gust of wind near rated wind speed can also be reduced while increasing the minimum clearance.
