This invention relates to the field of
flue gas
pollution control technology in
coal-fired power plants, and discloses a method for total
pollutant emission reduction in an
environmental protection island based on
morphological transformation and residual compensation. The method includes: acquiring real-time operating data of a smart
environmental protection island in a
coal-fired power
plant, generating a time-series
feature vector, and setting inlet boundary conditions; constructing a
pollutant morphological transformation mechanism model for each
environmental protection subsystem, inputting relevant data and inlet boundary conditions, and calculating the theoretical baseline concentration of pollutants; using an LSTM as an error-compensated prediction model, after training with historical data, inputting the current operating condition time-series
feature vector to obtain the
concentration prediction residual value, obtaining the deviation between the historical training conditions and the current operating conditions, calculating the
confidence factor, and generating a mixed
pollutant prediction concentration; finally, using
ammonia injection flow rate and other factors as optimization variables, setting constraints, and constructing an objective function with the lowest total cost to obtain the
optimal control parameter set, thereby achieving optimized control and pollutant emission reduction of the environmental protection subsystem. This invention significantly improves the pollutant emission reduction effect.
