The invention relates to a data analysis-based power grid lean management system. The data analysis-based power grid lean management system includes power equipment, a data acquisition module matched with the power equipment, a distributed database connected with the data acquisition module, a data calculation and analysis module connected with the distributed database, an output control module connected with the distributed database and the data calculation and analysis module, and a mobile terminal connected with the output control module. With the data analysis-based power grid lean management system adopted, the problems of imperfection and irrationality of an existing power grid equipment operation management system can be solved. The data analysis-based power grid lean management system has the advantages of simple structure and easiness in implementation, and can be widely applied to the power grid equipment operation management system field.
