Abstract: The wind turbine reserves the reserved backup capacity with super speed control,It can achieve inertial response and frequency adjustment at the same time2Personal control target。Traditional control strategies often use insufficient use of backup capacity of the crew,The maximum frequency adjustment advantage of the super -speed aircraft crew has not been played。For this,On the basis of in -depth research on the frequency control of the super -speed motor unit,The relationship between the inertia response and the frequency regulation and the steady -state operation point respectively,M88 Online Live CasinoM88 Online Live CasinoI proposed the super -speed wind power unit frequency adjustment control strategy considering the optimal running point。This control strategy finds the optimal running point at different wind speeds through the frequency regulation energy model,Make full use of the free -capacity participation frequency adjustment of the wind power unit,To achieve a frequency drop speed、Optimization coordination between depth and steady -state deviation。inDIGSILENTConstruction system simulation model for verification,The results indicate the controlStrategy can improve the dynamic frequency response characteristics of the system at different wind speeds,At the same time, it can ensure the stability of the wind turbine's own operation.
