摘要

本文研究了蒸汽轮机-燃气轮机联合循环电厂选择性催化还原(SCR)系统各过程变量间相对功率贡献率(PCR)的计算方法。PCR用于选择要考虑的系统统计模型中的过程变量。首先，我们展示了一种使用基于rbf - arx的SCR模型计算PCR的方法。接下来，我们展示了PCR在评估鉴定系统中的有效性。最后，我们考虑了一种基于Otomo-Nakagawa-Akaike方法的一般平稳控制系统PCR计算方法，该方法适用于上述SCR系统。

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.
