Control of Wind Turbine with Induction Generators

The recently increasing of energy demands from Asian countries and world face the problem of energy due to many undesired effects, Primary, the world economy is based on fossil fuels and mainly oil prices have double in last five years and Secondary, environmental threats and greenhouse gas effects are increasing then we have to focused on the renewable energy like wind energy. This paper provides the controlling of wind turbine with induction generators interfaced to grid with power electronics converters is best for the wind turbine power because the induction generators provides constant frequency and voltage to grid with power electronics converter technology. It also improves the power performance of the wind power turbines for grid because it reduces the all harmonics and noise from the grid. In this project, using of PWM technology with transformer topology to convert DC voltage to AC voltage to grid, simulation of wind turbine interfaced to induction generators by use of variable speed dc motors, combining power output of induction generators to charge common dc bus bar and also using feedback mechanism to sense output ac voltage and control by PWM technology with duty cycle correction.
