Abstract
Controlled resistive loads can
contribute to damping of electro-mechanical
oscillations. This paper presents an on-off
damping controller for a single machine system. It
was used at a field test in southern Sweden to damp
oscillations of a 0.9 MW hydro power generator.
The controller used estimated machine frequency as
input and controlled a 20 kW resistive load via
thyristor switches. The field measurements are
compared to time simulations and a systematic
procedure for tuning the controller is given. The
results indicate that on-off control of active loads
is effective in terms of added damping and that it is
simple to tune and implement
