Green Future – Simulations Models for Wind Power Plant Analysis

The paper is proving insights into wind power plants modeling and analyzing, focusing on doubly fed induction generator-DFIG as the best solution for mid power range, providing the best power output over the variety of wind power ranges. Firstly we present the common technologies utilized for wind power plants, focusing on DFIG system. Afterwards Wind data analysis is described with an example for area with ideal wind speeds through year in Lower Carinthia, Austria. The wind data is sorted and extrapolated to needed values using Matlab script. In last part wind models are used to analyze energy production in typical operating cases: wind velocity change, voltage drop and so on. The model used in Simulink is part of Simulink PowerSystems library, but is has been modified to fit into our analysis with parameters of our systems.
