CONTROL DEVICE FOR TURBINES WITH SPEED AND OUTPUT CONTROL

摘要

A control device for turbines with speed and output controllers, in which the output controller has an integral component with or without an output value limiter, characterized in that the speed controller and the output controller are functionally independent of each other over the whole working range, in that the speed controller also has an integral component and in that the correcting variables of the two controllers are conducted to a minimum limiter acting as input signals, in which the smaller correcting variable, as output signal of the minimum limiter, takes over the direction of the correcting element of the correcting variable controller.
