Controlbined with Figures ten and 11, it may be observed that the improved control method Combined with Figures 10 and 11, it could be seen that the enhanced manage approach can properly promote the stabilization of wind turbine terminal voltage. Under the can effectively market the stabilization of wind turbine terminal voltage. Below the preprevious manage, the terminal voltage of your wind turbine generator drops to 67.8 on the vious handle, the terminal voltage of the wind turbine generator drops to 67.8 with the initial stable value at its lowest point. Beneath the improved control approach, the terminal initial stable worth at its lowest point. Below the improved handle method, the terminal voltage drops to 93.7 at its lowest point. The voltage oscillation amplitude is lowered voltage drops which improves the program stability and delivers a extra stable grid voltage substantially, to 93.7 at its lowest point. The voltage oscillation amplitude is reduced significantly, which improves the technique stability and provides a far more QO 58 In Vitro steady grid voltage for wind turbines. for wind turbines. 2. Active energy output of Hornsea 1B 2. Active energy output of Hornsea 1B The active energy output curves of Hornsea 1B are shown in Figure 12. In the off-grid The active power output curves of Hornsea 1B are shown in Figure 12. Inside the off-grid accident of Hornsea wind farm, the active power output of Hornsea 1B dropped from accident of Hornsea wind farm, the active power output of Hornsea 1B dropped from 400 400 MW (1 pu) to about 200 MW (0.5 pu) and then recovered, but sooner or later, all wind MW (1 pu) to about 200 MW (0.five pu) then recovered, but sooner or later, all wind turbine turbine generators on Hornsea 1B reduced to 0 MW as a result of overcurrent protection in generators on Hornsea 1B decreased to 0 MW because of overcurrent protection within the the generators. generators.1.six 1.four 1.for wind turbines. two.
