Transient Energy Function and Oscillation Analysis of Doubly-fed Wind Turbines Considering Variation of Wind Speed
In order to study the influence of tower shadow effect and wind shear on the output power of wind turbines
the doubly-fed wind turbines are used as case study. Firstly
the transient energy function of the doubly-fed induction generator is derived by considering the variation of wind speed. Secondly
the periodic power fluctuation characteristics
frequency response
and oscillation mechanism of wind turbines are studied. Finally
a single-machine infinite system model including the wind speed model is built and simulated on the PSCAD/EMTDC platform. The influence of the tower shadow effect and wind shear on wind turbines is analyzed through the variation of power fluctuations and transient energy of wind turbines. The simulation results show that the tower shadow effect and wind shear cause the power fluctuations of the wind turbines. When the power fluctuation frequency of the wind turbines is equal to the natural oscillation frequency of the wind turbine shafting
