Emulation of static and dynamic characteristics of a Wind turbine using Matlab/Simulink

In this study a separately excited direct current (DC) motor is used to emulate the static as well as the dynamic characteristics of a Horizontal axis Wind turbine (HAWT) which is further driving a Permanent magnet synchronous generator for power generation. This work considers and implements:- Dynamics of the inertia of turbine-generator set; 3 pulse oscillations caused due to tower shadow effect (for a 3 blade HAWT); Mathematical modeling of turbine rotor characteristics. Wind speed reference is given either from recorded wind speed data via a 2-D look-up table or a random sequence generator available in Simulink. The PMSG connected to emulator is maintained at a DC-Link voltage of 1 kV through a closed loop generator control to provide a constant electrical load for prime mover i.e. emulator itself. This whole work is developed and implemented on software environment of Matlab/Simulink 2009a.
