Giant hydraulic power plant state maintenance model construction method and system

Abstract

The invention discloses a giant hydraulic power plant state maintenance model construction method. The method comprises the steps of firstly collecting the hydraulic power plant equipment operation state information; performing diagnostic analysis; obtaining the equipment operation state evaluation; evaluating a system state maintenance strategy according to the state; and ending the maintenance process of the equipment until the equipment runs normally. According to the giant hydraulic power plant state maintenance model construction method provided by the invention, the operation reliabilityof the equipment can be improved, and the service life of the equipment can be prolonged by 1-3 years in the life cycle, the equipment maintenance cost is reduced, and the equipment purchase and installation funds can be saved within the service life period of the electromechanical equipment. The method comprises the following steps of taking prevention of equipment faults as a center, classifying all system equipment, analyzing the possible fault modes of different types of equipment, determining the fault mode of each type of equipment, formulating the corresponding preventive monitoring and maintenance tasks and periods thereof for each type of fault modes, and realizing prevention of the equipment faults by utilizing the state maintenance.

Description

technical field [0001] The invention relates to the technical field of hydropower plant operation and maintenance, in particular to a method and system for constructing a condition maintenance model of a giant hydropower plant. Background technique [0002] Traditional equipment maintenance is mainly based on regular maintenance and periodic testing, which is difficult to adapt to the maintenance of equipment in the modern power industry; if the maintenance work is carried out according to the principle of regular maintenance, it will cause a certain degree of over-maintenance or under-maintenance, which will reduce the reliability of equipment operation and reduce the quality of equipment. Life cycle, while increasing equipment material procurement and maintenance costs, will adversely affect the safe and stable operation of equipment, and it is difficult to scientifically and reasonably control maintenance costs. Contents of the invention [0003] The object of the prese...
