The invention discloses a method for calculating a recommended maintenance grade of
hydropower main equipment, and relates to the field of
industrial internet platforms, equipment maintenance and
hydropower equipment. The method aims at solving the problems that an existing maintenance decision lacks long-term planning and special project requirements are not considered sufficiently, equipment maintenance grades are intelligently recommended by integrating multiple dimensions, and according to
equipment state evaluation data, equipment states are matched through
score state evaluation and dimension state evaluation; secondly, in combination with a rolling
maintenance plan, equipment maintenance interval duration and associated items, a recommended maintenance level is automatically determined by utilizing a
rule engine; and finally, calculating the equipment maintenance period based on the maintenance grade and the extended straight line construction period of the equipment associated project. The
automation and intelligence of the maintenance decision of the
hydropower main equipment are realized, and the scientificity and accuracy of the maintenance decision are improved; the application of the method can significantly improve the maintenance efficiency and effect of the hydroelectric equipment, ensures the long-term stable operation of the equipment, reduces faults and
downtime caused by improper maintenance, and has important practical value.
