Mathematical Models of Specific Elements of Wind Energy Conversion Systems Based on Induction Generator

In the complex case of wind energy conversion systems (WECS) analysis and synthesis, the mathematical models of each component element are required. In the paper are presented some contributions to preset values establishing strategies and models of specific elements: rotation speed and voltage preset values establishing strategies, a simplified fixed blade wind turbine model, the induction generator squirrel rotor induction generator Park mathematical model, specific to current frequency converter supplier use, current frequency converter inverter model. The presented models are used for WECS analysis in its specific transient regimes as well for its controller design.
