Abstract:
The present thesis is dedicated to high performance control of a
variable speed permanent magnet synchronous generator with
two back to back PWM converters for renewable energy
applications in general and for wind applications in special.
The wind power potential in many countries around the world has
led to a large interest and fast development of wind turbine (WT)
technology in the last decade. The integration of a high level of
wind power into electrical network implies new challenges as well
as new approaches in operation of the power system. According
to the new requirements the wind turbines should stay connected
and contribute to the grid in case of disturbances such as voltage
sags, dips. The grid side inverter capability to work both in gridconnected
but also in stand alone mode as well as the protection
in the case of the fault event are considered to be the most
challenging in terms of control strategy and the limited fault
current.
The main goal of the thesis is to offer new high performance
solutions in the area of control permanent magnet synchronous
generator with two back to back PWM inverters for wind
applications.
