Sophisticated power electronic apparatus and their digital control systems are
finding increasing applications in electric power systems at generation, transmission,
distribution and utilization levels. It is essential to carry out rigorous
performance evaluation of such apparatus before commissioning. Field Programmable
Gate Arrays (FPGAs) are becoming an attractive platform for
accelerating computationally intensive applications.
This thesis presents a FPGA-based real-time digital simulator for power
electronic drives based on realistic device characteristics. A 3-level 12-pulse
Voltage Source Converter (VSC) fed induction machine drive is implemented
on the FPGA. The system components include the 3-level VSC, the induction
machine, the direct field oriented controller, and the pulse width modulator.
Both system-level and device-level IGBT models are utilized to implement the
VSC. The VSC model is computed at a fixed time-step of 12:5ns allowing an
accurate representation of the IGBT nonlinear switching characteristics.
Altera Startix EP1S80 and EP3SL150F1152C2 FPGA boards utilized for
the real-time simulation. All models were implemented in VHDL. The FPGA
boards were interfaced to external DAC boards to display real-time results on
the oscilloscope. The real-time results were validated using an off-line cosimulation
set-up using the SABER and MATLAB/SIMULINK software. / Power Engineering and Power Electronics
