| Abstract |
In the following paper the autonomous power
generation system includes a doubly fed induction generator is
described. A simplified topology of the power electronics
converter, connected to the rotor, is applied. Subsynchronous
range of speed is main region of operation but small, negative,
close to rated slip, is also possible. An external source is used
for an initial excitation of the generator and then a converter
connecting rotor and stator is used to control stator voltage. The
space vector theory is used for the control algorithm. The stator
voltage vector components in x and y axes in the rotating
reference frame are responsible properly for the stator voltage
amplitude and frequency. In this way the stator voltage
frequency and amplitude are speed independent. A PSIM
software is applied for regulators quick designing and tuning. A
laboratory system including 1.5kW slip-ring machine is build
and tested. As a controller the floating point processor Sharc™
with a programmable unit ALTERA™/FPGA support was used.
Results of the simulation tests and oscillograms from the
laboratory setup are presented in the paper. |
