Abstract

According to the inventive method, excessive load changing speeds (10) are to be detected during the operation of the turbine (3). In the event of excessive load changing speeds, at least 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) serves to carry out said method and comprises a setting unit (11) for effecting the momentary throttling of the at least 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 at least two actuating signals (19, 21) for controlling the turbine valve (15) can be generated. The first actuating signal (19) serves to actuate the turbine valve (15) in the opening direction thereof, and the second actuating signal (21) serves to actuate the turbine valve in the closing direction thereof.
