MATLABSolutions demonstrate how to use the MATLAB software for simulation of This paper represents the modeling and simulation of 2 MW Direct Drive PMSG Wind energy conversion system (WECS). The modelling of wind turbine and PMSG is carried out in simulink to determine its parameter. WECS consists different components namely Wind turbine, Generator, rectifier-inverter, controller system including transformer, grid etc. The PMSG and converter model are established in the d-q model.

Abstract

This paper presents the modelling and simulation of wind turbine with permanent synchronous generator. In this paper, the modelling and simulations of a variable-speed wind turbine along permanent magnet synchronous generator is presented. Now a day, the energy production by wind generators has recently been increasing, because its creation is green; therefore, the technology designed for the establishment of energy through wind turbine brings great challenges in the exploration. A mathematical model of wind turbine is necessary to understand the behaviour of the wind turbine over its area of operation since it allows for the evolution of inclusive control algorithms that aid in ideal operation of a wind turbine system. Modelling gives us an overview of the proposed system and also allow control of wind turbine system’s performance. Outcome results show that the speed regulation was very good. In long lasting regime, the imbalance of rotor speed was almost inconsiderable in spite of the uninterrupted imbalance of the wind speed within the interval of 12 to 15 m/s. Simultaneously, the active and reactive power obtained were in accordance with the simulation predetermined values.

Introduction

In these days two types of generator used in large scale WECS for convert the wind power into electrical power which are doubly fed induction generator (DFIG) and Permanent magnet synchronous generator (PMSG). PMSG is a Direct Drive type generator; and don’t require gear box and excitation current so PMSG show good performance in WECS. MATLAB/SIMULINK is a graphical software package for modeling, and simulating WECS system. WECS with PMSG can avoid the problem of wear and tear of gear, it can help wind turbine operate more reliable and reduce maintenance. The paper represents a 2 MW variable PMSG WECS with the control strategy. WECS can be used in two different ways namely isolated standalone system and Grid connected system. Standalone systems are employed to the needs of small scale industries for rulers areas, such system are located at for off places/remote areas. Grid connected system increased energy efficiency, robustness, voltage support, diversification of energy sources, reduced transmission and distribution losses and reliability of the system. This paper described the model and simulation of PMSG based on WECS in d-q model

SYSTEM CONFIGURATION

In the present scenario, the world is shifting toward the renewable energy sources as like wind energy to suppress electricity shortage and to control the fast end of fossil fuels. Being a part of this a wind turbine modelling is presented with its simulation by using PMSG. The purpose of this paper is to analyse the dynamics of the horizontal axis wind turbine (HAWT). In the following section, an overview of the model is presented by utilizing the mathematical modelling equations of wind turbine system and PMSG respectively. MATLAB/simulation is used for modelling and analysis.
