Abstract: “Short circuit (S.C.) generator is very much different from the conventional generators used in power generating stations. Driving S.C. generator and extracting power from it is indeed a specialized job. Power drawn from S.C. generators during test is much high in magnitude hence it has to be taken care that the supply grid should not to be loaded during the period of short circuit. Normally generators are driven with different kinds of prime mover. With the advent of the solid state devices it became possible to run a generator even without a prime mover. This paper describes the control techniques used during different Test Sequences for a 1500 MVA, 12.5 kV, 3000 rpm, 50 Hz S.C. Generator. These techniques are verified practically on actual test equipments and supported with the resultant waveforms. This generator is functional at Bhopal unit of Central Power Research Institute.”
