Title:
CONTROLLER FOR GOVERNOR OF STEAM TURBINE
Document Type and Number:
Japanese Patent JPS57186005
Kind Code:
A
Abstract:
PURPOSE:To stabilize the interior of an electric power supply system, by adding a mechanism for comensating the set load value of a changing pressure turbine and by effecting the same governor-free compensation for the changing pressure turbine as a constant pressure turbine. CONSTITUTION:A signal 1 for adjusting a steam regulating valve depending on the deviation of the pressure of main steam and another signal 2 for adjusting the steam regulating vlve depending on the deviation of the load are applied to an opening degree control unit 3. The output signal 6' of a dead zone 7 controls the gate of a thyristor 9 to drive a governor motor 10. The frequency deviation signal 13 of an electric power supply sysem is applied to a speed government ratio compensator 14 to compensate a set load value 11. New compensation is effected on an opening degree signal 4 by a signal 26 corresponding to the difference between the frequency deviation of the electric power supply system and the output signal of a speed government ratio compensator 22. As a result, a changing pressure turbine is enabled to perform the same governor-free operation as a constant pressure turbine.
