Emergency State Control For Power Station Operating Using Process Computer

Emergency state control is an important research topic which presently receives a lot of attention [1]. For this operating condition the design of a digital power station control is discussed in this paper for a specific model using pseudo-frequency domain analysis in this manner it is possible to derive DDC units for each control loop such that prespecified step responses of the process variables are obtained. Furthermore it is possible to guarantee that the admissible rates of change are fully exploited without exceeding them. Using interactive computing methods in the pseudo-frequency domain results in digital control structures which widely differ from the present ones. Since the numerical implementation is straight forward it seems realistic that the improved power reserve and stability behaviour may substantially contribute towards emergency state control.
