Method and system for correcting digital twinborn model data of evaporation area of thermal power plant

Abstract

The invention discloses a method and system for correcting digital twinborn model data of an evaporation area of a thermal power plant, and the method comprises the following steps: obtaining the operation physical data of a physical system of the evaporation area, carrying out the estimation of the physical quantity of the evaporation area through a self-adaptive square root unscented Kalman filter, and obtaining the real operation physical data; using the mechanism model and a neural network to construct and obtain an evaporation zone digital twinborn model; and synchronously operating the evaporation zone physical system and the evaporation zone digital twinborn body model to obtain real operation data and twinborn data, and correcting the twinborn data based on the real operation data. According to the method and system, the adaptive square root unscented Kalman filter, the neural network and other methods are combined, and real-time correction of the model and data of the digital twinborn in the evaporation area can be achieved, so that the consistency simulation of the digital twinborn on the running condition of the evaporation area is achieved.
