description The invention relates to the technical field of thermal power engineering, and particularly discloses a high-precision intelligent prediction method for distorted NOx concentration of an SCR denitration system. The method comprises the following steps: establishing an NOx concentration measurement data switching control framework matched with the working states of an inlet NOx concentration analyzer and an outlet NOx concentration analyzer of the SCR system; under the input of parameters, carrying out training to obtain a distortion state inlet NOx concentration intelligent prediction model and a distortion state outlet NOx concentration intelligent prediction model; realizing switching between the distorted NOx concentration and the non-distorted NOx concentration by independently and specifically adjusting characteristic parameters of a delay module system on the downstream of the inlet or outlet NOx concentration intelligent prediction model, and finally, obtaining all-time high-precision NOx concentration
