Issues regarding the modeling and simulation of wind energy conversion system’s components

The wind energy conversion systempsilas (WECS) analysis requires the priory knowledgepsilas regarding the mathematical models for all component subsystems. The paper highlights some contributions to the preset values establishing strategies and models of certain components: rotation speed and voltage preset values establishing strategies, a simplified wind turbine model (fixed blade turbine), the squirrel cage/wound rotor asynchronous machinepsilas mathematical model (the Park equations), specific to current frequency converter supplier use, frequency inverterspsila model. The elaborated models are used in the WECS analysis in its specific steady state / transient regimes as well for the controllerspsila design and implementation.
