This paper presents a direct power control strategy for a doubly fed induction generator by using an artificial neural network controller with the multilayer perceptron structure. This controller generates the direct- and quadrature-axis rotor voltage signals from both the stator current and voltage that are measured by the Hall sensors. The input variables of the control system are the rotor speed,...
This paper proposes a novel rotor position estimation algorithm used for reference frame transformation in the direct power control (DPC) of a doubly-fed induction generator (DFIG) in wind power applications. The proposed algorithm can be used as a primary rotor position information provider to replace the rotor position sensor or a backup rotor position information provider during the malfunction...
As the wind power penetration level increases, the inertial response of a wind power plant (WPP) is important to the grid under load and generation imbalance. In this paper, we present coordinated WPP control for frequency support under wake effects. By de-loading the power from a WPP, the inertial response can be obtained from the kinetic energy of wind turbine rotors. The coordinated WPP control...
