The great interest shown today in the double-fed induction generator in wind chain prompted us to analyze the performance of the separate control of active and reactive power generated by the stator of double-fed induction generator connected to the grid. The objective of the separate control of active and reactive stator powers is to provide constant power to the power grid whatever the variation of the wind speed, and to provide reactive power to correct the power factor. In this article, we present the modeling and an integrated vector control in a double-fed induction generator wind chain, which aims to independently control the active and reactive power generated by the double-fed induction generator. Knowing that the direct control of active and reactive power delivered to the grid with conventional proportional integral controllers provides good performance in permanent diet but a variable speed wind, the measured powers hardly follow the set values. To remedy this problem, we replace the conventional proportional integral controllers with proportional integral–fuzzy controllers to ensure good performance and robustness of the control of separate powers. To justify this choice, it is necessary to evaluate and compare the separate control loop for active and reactive power with conventional proportional integral controllers than with proportional integral–fuzzy controllers under the same constraint variable speed wind. The second part treated in this article is to reduce the harmonic pollution caused by the supply of the double-fed induction generator–based inverters and controlled rectifiers, which strongly infect current line. This phenomenon can have an adverse effect on the loads connected to the grid and equipment of proximity. The insertion of a filter system in the chain is needed, except that the strain of the volume and the reflection require a high cost for a more advanced and more optimal solution. Our contribution to this part is to replace the supply of the double-fed induction generator rotor side by a matrix converter controlled by the modulation technique of the difference errors between the measured values and the desired output values (least mean square errors).

“…Prior to hardware implementations, simulations were performed to predict the behavior. A laboratory model test-rig of the SPMC was then constructed to perform investigation [3], [4].Industrial application of matrix converter is still very limited because of some practical issues like common mode voltage effects, high susceptibility to input power disturbances and low voltage transfer ratio [5]. In order to extend the horizon of matrix converter into several distributed power sources application, the objective of this research work is to simulate practical matrix converter.…”

Computer Applications in Power System is place an important role to verify the system performance and real time monitoring systems. Most of the Electrical system uses LABVIEW and other software to monitor real time electrical transition. In this paper we are focusing on Power Electronic Conversion system. Power Electronic System is easily simulated using MATLAB Software. Here we are giving easy simulation of Matrix converter and its result. Clean power development in power electronic system is an emerging area of research in Electrical Engineering. Most of the power electronic system introduces harmonics in power system. Elimination of harmonic is a tedious process. Different control strategy should be developed to reduce the harmonic. In Rectifier fed Inverter system has many disadvantages because of DC link filter. Matrix converter avoids this DC link filter and output approaches input. In this paper we have simulated Single phase Matrix Converter. Computer based simulation using MATLAB and Real Time implementation using PIC89C51 validate its originality. Finally we have compared different values of Harmonics.

“…The objective of this research is to propose a PWM strategy to reduce THD, which is reported to R, RL and Motor load. The THD is investigated in the matrix converter fed ASD [9], [10]. Matrix converter controller is modified with the addition of a fuzzy controller and thereby a new fuzzy controller is proposed together with Space Vector PWM strategy.…”

In this paper, Fuzzy Logic controller is developed for ac/ac Matrix Converter. Furthermore, Total Harmonic Distortion is reduced significantly. Space Vector Algorithm is a method to improve power quality of the converter output. But its quality is limited to 86.7%.We are introduced a Cross coupled DQ axis controller to improve power quality. The Matrix Converter is an attractive topology for High voltage transformation ratio. A Matlab / Simulink simulation analysis of the Matrix Converter system is provided. The design and implementation of fuzzy controlled Matrix Converter is described. This AC-AC system is proposed as an effective replacement for the conventional AC-DC-AC system which employs a two-step power conversion.
