Abstract
PURPOSE: To simplify the structure of a turbine controlling system and to enhance reliability of its operation, by employing such an arrangement that a load limiting means can function correctly to both of increasing and decreasing of the steam pressure by use of a single pressure detector.
CONSTITUTION: The output of a turbine 1, connected with a generator 2, is adjusted by a control valve 4 which is actuated by a servomotor 5. The servomotor 5 is controlled on the secondary oil pressure developed in a secondary oil passage S by a conventional speed control means 6. A load limiting means V detects the vacuum in a condenser 3 and lowers the secondary oil pressure in the passage S in response to the deviation of the value of vacuum in the condenser 3 from an optimal value. Here, the load limiting means V is composed of a lever 13 connected to a piston 11 and an injection pipe valve 7 constituting a pressure detector, and secondary oil pressure setting means 17, 18 connected to the lever 13 in the manner of facing toward each other. The means 17, 18 are designed to determine the secondary oil pressure by preceding a lower one of the two oil pressures.
