The invention discloses a giant hydraulic power
plant state maintenance model and a construction method. The method comprises the steps of collecting operation state information of various devices ofa hydraulic power
plant; Carrying out analysis; Carrying out
score evaluation on the equipment; Determining the equipment as a
normal state, an attention state, an abnormal state and a dangerous state; And finally, making an equipment facility maintenance level and a
power station annual equipment
maintenance plan according to the level state of the equipment. On the basis of periodic overhaul stipulated by the country and industry, formulating an
equipment state overhaul strategy by taking equipment operation reliability as a center and according to equipment operation trend annual analysis,risk and service
life evaluation and other means, and determining an equipment overhaul interval, outage time and an overhaul mode of an overhaul project according to diagnosis and evaluation results.And the equipment hidden danger can be timely discovered and eliminated, equipment faults and even accidents are avoided, the service life of the equipment is prolonged, the
workload of maintenance personnel and the
maintenance management difficulty are reduced, and the
maintenance management efficiency is also improved to a certain extent.
