Powerful wind turbine modelling using Matlab/Simulink

Abstract

Due to the growth of renewable energies installed in the energy matrix of the Argentine Republic, failures related to these developing and constantly growing technologies are evident, especially in some systems subjected to large permanent loads. A clear example of this is the repeated failures of power components in frequency converters. To be able to understand the causes and solutions of these systematic failures related to these system components in the future, in this paper, a state-space variables model of the set frequency converter–power transformer coupled to an electrical network will be presented, allowing for future optimal control implementations and parameter identification based on real measurements available in installed wind generators. The measurements used will be real data obtained from wind turbines to verify their response in different states of the electrical network to ultimately verify the working conditions of the power components mounted on frequency converters, once the model parameters in this paper will be correctly identified in the near future.
