Adaptive Fuzzy Control for Variable Speed Wind Systems with Synchronous Generator and Full Scale Converter

Control systems for variable-speed wind turbines (WTs) are continuously evolving toward innovative and more efficient solutions. Among the various techniques, fuzzy logic is gaining reputation due to its simplicity and effectiveness. In this chapter, after a review of fuzzy logic based control applied to wind energy conversion systems, a sensorless peak power tracking control for maximum wind e...

Control Strategy for Variable-Speed, Stall-Regulated Wind Turbines

A variable-speed, constant-pitch wind turbine was investigated to evaluate the feasibility of constraining its rotor speed and power output without the benefit of active aerodynamic control devices. A strategy was postulated to control rotational speed by specifying the demanded generator torque. By controlling rotor speed in relation to wind speed, the aerodynamic power extracted by the blades...

Small Fault Diagnosis of Front-end Speed Controlled Wind Generator Based on Deep Learning

In view of the difficulty in diagnosing the early small faults of front-end controlled wind generator (FSCWG), this paper proposes a small fault diagnosis methods based on deep learning. The method adopts a deep learning method, uses vibration data under several different small fault patterns of FSCWG as input of the model and gets deep learning diagnosis model by learning complicated implicit ...

Intelligent Control for the Variable-Speed Variable-Pitch Wind Energy System

In this paper, a new type of multi-variable compensation control method for the wind energy conversion systems (WECS) is presented. Based on wind energy conversion systems, combining artificial neural network (ANN) control and PID, a new type of PID NN intelligent controller for steady state torque of the wind generator is designed, by which the steady state torque output is regulated to track ...
