METHOD AND DEVICE FOR REGULATING THE ROTATIONAL SPEED OF A TURBINE CONNECTED TO AN ELECTRIC POWER SUPPLY MAINS BY MEANS OF A GENERATOR

Abstract According to inventive method excessive load changings speeds (10) are to be detected during the operation of the turbine (3).In the event of excessive load changings speeds,atleast one turbine valve(15) of the turbine (3) is momentarily throttled and ,after the load change the rotational speed of the turbine(5)is subsequently regulated with regard to the new operating load.The inventive device (1)service to carry out said method and comprises a setting unit(11) for effecting the momentary throttling of the atleast one turbine valve(15)and comprises an arithmetic unit(17),which is provided for regulating the rotational speed according to a load change and by means of which atleast two actuating signals(19,21)for controlling the turbine valve(15) can be generated.The first actulating signal(19)service to actuate the turbine valve(15) in the opening directiopn there of,and the second actuating signals (21) service to actuate the turbine valve in the closing direction there of
