“…In order to track maximum power we change stator electrical frequency 0 . The amount and direction of change is estimated by the ES feedback loop (Komatsu et al, 2001;Kumar et al, 2009;Pan et al, 2008;Ghaffari et al, 2014) (Eqs. 14-16).…”

In this paper, we have presented maximum power point tracking (MPPT) algorithm for variable speed fixed pitch (VSFP) wind power plant connected to grid. The wind power plant is based on squirrel cage induction generator (SCIG) fed by a matrix converter (MC). Matrix converter is a power electronic interface between generator and grid, which facilitates the mechanism of MPPT algorithm. For maximum power point tracking, we have used extremum seeking scheme, which, unlike other MPPT techniques is a nonmodel based MPPT algorithm. In this paper sinusoidal signal has been used as a search disturbance signal. The performance of the ES algorithm has been checked for different wind velocities. In the latter section of this paper, we have done stability analysis of extremum seeking for wind energy conversion system (WECS) using single perturbation method.

“…But all these suffer from the demerits of poor device utilization; the produced variable DC-link voltage causes distortion of currents and voltage of generator and has poor power factor operation. Out of these configurations, two commonly investigated matured alternatives for wind power generation purposes are the AC/DC/AC converter [6][7][8][9][10] and the matrix converter (MC) [11][12][13][14][15][16][17][18]. Although the AC/DC/AC converter has a high energy density and is relatively low in price, there is a serious concern with its large DC-link capacitor due to its size, weight, volume, and premature failure [15,17].…”

“…In recent times, the MC has received a lot of attention by researchers for its application in wind power because of its high merit over traditional AC/DC/AC converters, as it is free from commutation problems, has improved voltage gain with simplified control, is compact in size, is light weight, and has high reliability due to the absence of a DC capacitor and extremely fast transient response [15]. Also, it provides the flexibility of more control levers for independent control on frequency, voltage magnitude, phase angle, and input power factor.…”

This article presents the development of a novel control for matrix converter interfaced permanent magnet wind energy conversion system. Here, an adaptive fuzzy control algorithm incorporated with a reversed matrix converter is proposed to yield maximum energy with enhanced dynamic performance and low harmonic characteristics. The control algorithm is implemented using a dSPACE DS1104 real-time board (dSPACE, Paderborn, Germany). Feasibility of the proposed system has been verified through simulation and experiment results using a laboratory 1.2-kW prototype of a wind energy conversion system under dynamic conditions.

Abstract:The matrix converter or pulse width modulated frequency changer, invented in the mid-1980s, is a direct power conversion device that can generate a variable voltage and frequency from a variable input source. Industrially, it is applied in adjustable speed control of induction motor drive, power quality conditioner, and traction applications.The aim of this paper is to evaluate the steady state characteristic behavior of an induction machine in terms of its speed and torque when driven by a three phase indirect matrix converter at reduced harmonics. Similarly, projecting an AC-AC matrix converter that ensures a uniform synchronization in frequency and voltage supplies between the three phase wound rotor machine and the transformer's grid voltage supply is discussed in the Scherbius scheme. The different methods of torque calculations pertaining to some selected machine circuit diagrams are presented for comparison and analysis. Emphasis on the torque-speed characteristics of the machine at varied resistance and slip values were graphically analyzed in MATLAB to determine the degree of torque-speed dependence on the rotor resistance and slip. The overall behavior of the machine under motoring, plugging, and regenerative modes was considered in this work, while a detailed Simulink modeling of an indirect matrix converter on the Scherbius drive scheme is also presented for further analysis.
