Power plant denitration operation optimization method and system based on numerical simulation and data analysis

The invention discloses a power plant denitration operation optimization method and system based on numerical simulation and data analysis, and the method comprises the steps: collecting the actual operation data of a coal-fired power plant, and carrying out the preprocessing of the actual operation data; calculating the relationship between the actual operation data by adopting a grey correlation analysis method, and sorting the obtained grey weighted correlation degrees; establishing a prediction model based on a neural network, taking strongly-associated actual operation data as input, and taking denitration energy consumption and denitration efficiency as output of the prediction model; verifying the prediction model by adopting historical actual operation data of another period of time; when the denitration efficiency and the energy consumption reach the optimal balance point through the artificial bee colony algorithm, finding the optimal value of the adjustable variable in the actual operation data.
