On-off Control of an Active Load for Power System Damping-Theory and Field Test

Författare

Summary, in English

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
