  • Method for controlling the rotational speed of a turbine during load shedding
    Patent number: 6070405
    Abstract: A control system for controlling the rotational speed of a turbine for producing electrical power and a method for controlling the rotational speed of a turbine during load shedding include a control structure. The control structure can be connected to an actuator, which is used to control the rotational speed, and the control structure is used to control the rotational speed of the turbine during idling and/or insular operation of the turbine. An error signal which is dependent on a difference between a setpoint value and an actual value of the rotational speed, can be supplied to the control structure. During load shedding, the control structure supplies a closing signal to the actuator as a function of the error signal. The control structure combines the function of controlling the rotational speed during idling and/or insular operation of the turbine with the function of avoiding rapid shutdown of the turbine when load shedding occurs.
