Abstract :
Exciter stabilizing signals derived from shaft speed measurement have the potential to create torsional oscillations in turbo-generator units. Signals derived from accelerating power preclude this problem, but require an input proportional to mechanical power changes for satisfactory operation. A mechanical power signal has been derived from measurement of steam pressures and has been static exciter in the field.
