Intelligent control technology based on the aggregative stability indicator is then proposed, including the optimal operating condition database, intelligent control parameter search method and variable operation process optimization method. Finally, according to the knowledge-based, model-based and big datadriven fault diagnosis methods, the integrated fault diagnosis of complex systems is realized, and a digital twin-based intelligent operation and maintenance system for power systems is constructed. [Result]The application case of an intelligent power system operation and maintenance platform verifies the feasibility of realizing intelligent control and fault diagnosis functions. [Conclusion]The results of this study can provide valuable references for the research and design of intelligent engine rooms.
