Embodiment 1
[0043] As shown in the figure, the method for constructing the condition-based maintenance model of a hydropower plant provided in this embodiment includes the following steps:
[0044] Collect the operating status information of various equipment in hydropower plants;
[0045] Analyze and form equipment maintenance status evaluation information according to equipment operation status information;
[0046] The equipment state evaluation information performs score evaluation on the equipment to form a score rate of the equipment;
[0047] According to the scoring rate of the equipment, the equipment is determined as four levels of status: normal status, attention status, abnormal status, and dangerous status;
[0048] According to the grade status of the equipment, the maintenance level of equipment and facilities and the annual equipment maintenance plan of the power station are formulated; the maintenance levels of equipment and facilities include normal state maintenance, a...
Embodiment 2
[0058] This embodiment also provides a condition-based maintenance model of a hydropower plant, including an information collection and processing module, an equipment operation status diagnosis and analysis module, a status evaluation module, a status evaluation module, and an equipment and facility maintenance strategy module;
[0059] Information collection and processing module:
[0060] (1) On-line monitoring: According to the real-time monitoring of online monitoring systems such as the monitoring system, generator local on-line monitoring system, main transformer and reactor chromatogram online monitoring system, unit status monitoring system, vibration and swing protection system, etc., using the dynamic data analysis platform , intelligent operation and maintenance cloud system early warning information and equipment operation trends to focus on, and collect relevant information and data.
[0061] (2) In terms of offline detection, combined with equipment operation, m...

Abstract
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.
Description
technical field [0001] The invention relates to the technical field of condition-based maintenance of hydropower plants, in particular to a method and system for constructing condition-based maintenance models of giant hydropower plants. Background technique [0002] Under the current power system reform situation, the power market as a whole presents a trend of oversupply, and the competition among power generation companies is becoming increasingly fierce. The traditional planned maintenance model cannot well meet the needs of the power market; If the actual operating status of the equipment is not comprehensively evaluated, timely and effective maintenance cannot be organized when key components fail, which will adversely affect the safe and stable operation of the equipment. Through the research on the condition-based maintenance model of equipment and facilities, the maintenance cost and management difficulty of power plants can be effectively reduced, and the maintenan...
