A mathematical modeling method for wind-electric asynchronous-generator plant modes is introduced. The method employs a spline approximation of the solution to nonlinear algebraic equations of the plant’s electric part and, on this basis, numerical integration of the system’s differential equations. The method is illustrated with an example of mode modeling for a wind-electric plant with continuous and pulse control of the blades turning servomotor for the power output stabilization.
