On the relative power contribution between process variables of SCR control systems for ST-GT combined cycle power plants
This paper is concerned with a method of computing the relative power contribution ratio (PCR) between process variables of a Selective Catalytic Reduction (SCR) system in a steam turbine (ST)-gas turbine (GT) combined cycle power plant. The PCR is used to select process variables in the statistical model of the system to be considered. Firstly, we show a method for computing the PCR using a RBF-ARX-based modeling of the SCR. Next, we demonstrate the effectiveness of the PCR in evaluating the identified system. Finally, we consider about a method for computing PCR for general stationary control systems based on Otomo-Nakagawa-Akaike's method, which is applicable to the above-mentioned SCR systems.
