This article presents a sliding mode control (SMC) with artificial neural network (ANN) regulator for the doubly fed induction generator (DFIG) using two-level neural pulse width modulation (NPWM) technique. The proposed control scheme of the DFIG-based wind turbine system (WTS) combines the advantages of SMC control and ANN regulator. The reaching conditions, robustness and stability of the sy...

With the increase in energy power requirement and reduction availability of conventional fuel resources, practice generating electrical using renewable resources has gained importance. Wind is considered a significant resource commercially used for electricity generation. velocity varies continuously, hence, output wind generator varies. As result, turbine develops not at corresponding maximum ...

This paper presents the operation of doubly fed induction generator (DFIG) with Fuzzy Logic Control & an integrated active filter capabilities using grid-side converter (GSC). The main contribution of this work lies in the control of GSC using Fuzzy Logic Control (FLC) for supplying harmonics in addition to its slip power transfer. The rotor-side converter (RSC) is used for attaining maximum po...

The objective of this paper is to construct a wind generator system (WGS) loss model that addresses the loss of the wind turbine and the generator. It aims to optimize the maximum effective output power and turbine speed. Given that the wind generator system has inertia and is nonlinear, the dynamic model of the wind generator system takes the advantage of the duty of the Buck converter and emp...

The doubly-fed generators (DFIG) have clear superiority for the applications of large capacity and limited-range speed control case due to the partially rated inverter, lower cost and high reliability. These characteristics enable the doubly-fed wound rotor induction machine to have vast applications in wind-driven generation.In this paper Combined Vector and direct power control (CVDPC) strate...

This paper presents a novel type of variable speed wind turbine with a new drive train different from the variable speed wind turbine commonly used nowadays. In this concept, a synchronous generator is directly coupled with the grid, therefore, the wind turbine transient overload capability and grid voltage support capability can be significantly improved. An electromagnetic coupling speed regu...
