Dynamic carbon emission factor calculation method based on operation data of coal-fired unit

The invention relates to a dynamic carbon emission factor calculation method based on operation data of a coal-fired unit. The method comprises the following steps: extracting operation characteristic data of a thermal power unit; carrying out standardization processing on the extracted feature data; classifying the feature data according to the unit capacity; carrying out clustering on the classified data by adopting an improved K-means clustering method; establishing a coal-fired unit dynamic carbon emission factor calculation model based on a BP neural network; performing dimension reduction processing on the feature data by adopting a principal component analysis method, and finding out principal components according to contribution degrees of all the components; and analyzing the principal component and the correlation coefficient matrix, and determining a characteristic data category which is positively correlated with the principal component and has relatively large influence on the dynamic factor.
