A Stimulation Study of the Dynamic Power Control Method for VSCF Doubly-Fed Induction Wind Turbine Based on Labview

摘要

In wind power systems, wind turbine is a core component. The usual mathematical model of wind turbines are put forward under the circumstance of constant wind speed, that is, to study the characteristics of the active power and the slip ratio at a fixed rotor speed, but these models cannot fully describe the operation status of the wind turbines under actual circumstances; therefore, this paper endeavors to propose a mathematical model of wind turbine in the case of variable speed and achieve simulation system model through the Labview language. Based on this model, a dynamic power control strategy is further proposed and analyzed in theory. This theory lays a good foundation for the future design of dynamic power controller.
