ABSTRACT:
A quick power regulation for a power station system is achieved by activating energy storage mechanisms of the power station system process. The energy storage mechanisms are used to increase the generator power. At least the generator power and a thermal power extracted from the power station system process are determined as process variables. The process variables characterize the current operating state and determine position setpoint values of actuators. A device for a quick power regulation receives at least values of the generator power and a thermal power extracted from the power system process. The control device determines position setpoint values for a number of actuators connected to a steam turbine of the power station.
