Abstract: The application of the latest achievements of information technology to the design, manufacture, operation and maintenance of steam turbines contributes to the demand for efficient and flexible power generation of steam turbines under the new energy situation. The paper proposed the concept of "intelligent steam turbine", and illustrated its structure, characteristic and life-cycle solution. The artificial intelligence algorithms represented by machine learning and deep learning were introduced for the applications in design, control strategy, fault prediction, knowledge transfer and etc. of "intelligent steam turbine". Six key issues to be urgently solved in the development of "intelligent steam turbines" were concluded, which provides ideas and specific examples for its development.
