Abstract
The present invention discloses a determination method of a difference operation maintenance strategy of an electric power device. The method comprises: 1) the operation state of the electric power device is assessed. If the operation state is normal, any measure is taken, the electric power device is normally operated. If the operation state is an attention state or an abnormal state, the step is jumped to the step 2). If the operation state is a severe state, the step is jumped to the step 3). 2) The risk evaluation of the electric power device is performed. If the electric power device is a low-risk device, the maintenance is not performed, and the inspection and monitoring period is arranged. If the electric power device is a medium-degree risk device, the power failure maintenance is performed. If the electric power device is a high-risk device, the step is jumped to the step 3). And 3), the real life of the electric power device is determined. If a regulated life period is exceeded, the decommissioning processing is directly performed. If the regulated life period is not exceeded, the power failure maintenance is performed. According to the steps, the difference operation maintenance strategy of an electric power device is determined.
Description
Technical field
The invention belongs to status of electric power evaluation and repair based on condition of component field.
Background technology
Along with the development of electrical network power transmission and transforming equipment manufacture level, electrical network power transmission and transformation situation has had bigger improvement.In recent years the swift and violent growth of social need for electricity, electrical network scale expands rapidly, and electrical network power supply reliability is required more and more higher by society, how to arrange rational equipment operation maintenance strategy, raising equipment reliability of operation and economy to receive extensive concern.
At present, the height of state quality and risk that the operation maintenance strategy of power equipment is mostly based on equipment determines.Through development for many years, a series of complete evaluating status of electric power and the Guidelines of risk assessment and index are gradually formed, plant maintenance personnel can determine good and bad degree and the risk height low degree of equipment state according to directive/guide, and then makes power equipment differentiation operation maintenance strategy.
But, current equipment operation maintenance policy development mode is broadly divided into two classes:
One is, according to mostly determining according to single evaluation index, such as state evaluation result or risk evaluation results.
Two are, if the state estimation of equipment and risk evaluation result are all it is known that generally consider that the most serious evaluation result formulates operation maintenance strategy, to guarantee reliability and the safety of equipment.
Above-mentioned two class modes are when formulating O&M strategy, it is difficult to effectively take into account equipment reliability of operation and economy.For going deep into the internal relation of excavating equipment state and risk, rational equipment operation maintenance strategy, improves decision-making benefit.
Summary of the invention
Present invention aim to address the problem that power equipment reliability of operation (risk) and economy are difficult to take into account.
Employed technical scheme comprise that such for realizing the object of the invention, a kind of determination method of power equipment differentiation operation maintenance strategy, comprise the following steps:
1) running status of power equipment is assessed.
If normal condition, the most do not take any measure so that it is properly functioning.
If attention state or abnormality, then jump to step 2).
If severe conditions, then jump to step 3).
2) power equipment is carried out risk assessment.
If low-risk equipment, do not overhaul, set and patrol and examine and the monitoring cycle.
If moderate risk equipment, then interruption maintenance.
If excessive risk equipment, then jump to step 3).
3) power equipment actual life is judged.
If exceeding the life cycle of regulation, the most directly carry out retired process.
If not less than the life cycle of regulation, then interruption maintenance.
Further, described power equipment is transformator.
Further, in step 1), when assessing the state of power equipment, with reference to State Grid Corporation of China " power transmission and transformation equipment state assessment guidelines " (table 1), it is judged that the running status residing for power equipment is normal condition, attention state, abnormality or severe conditions.
The state grade of table 1 power transformer determines foundation
Further, step 2) in, the cycle patrolled and examined and monitor be 7 days once.
Further, step 2) in, with reference to State Grid Corporation of China " power transmission and transforming equipment risk assessment directive/guide " (table 2), it is judged that the risk status residing for power equipment is low-risk, moderate risk or excessive risk.
Table 2 equipment Risk table of grading
The beneficial effects of the present invention is: the invention provides a kind of determination method of power equipment differentiation operation maintenance strategy, first equipment is carried out state evaluation, determine the state grade of equipment, tentatively obtain the operation reserve of equipment: based on condition evaluation results, to being in attention, the equipment of abnormality carries out risk assessment, the equipment being in severe conditions is carried out life assessment, is gradually completing the formulation of whole power equipment differentiation operation maintenance strategy.The present invention effectively combines state and the risk of equipment when formulating operation maintenance strategy.Avoid the deficiency using single evaluation index to determine equipment O&M strategy so that operation maintenance strategy is the most reasonable, it is possible on the premise of ensureing equipment safe and reliable operation, improve equipment Management Level, reduce maintenance cost.Additionally, the method that provides of the present invention at most can complete the differentiation operation maintenance policy development under each state of equipment and risk class by 3 estimation flows, method simply uses, and is easier to be grasped by equipment operation maintenance personnel.
Accompanying drawing explanation
Fig. 1 is that the equipment differentiation operation maintenance strategy of the present invention determines flow process.
Detailed description of the invention
Below in conjunction with embodiment, the invention will be further described, but should not be construed the above-mentioned subject area of the present invention and be only limitted to following embodiment.Without departing from the idea case in the present invention described above, according to ordinary skill knowledge and customary means, make various replacement and change, all should include within the scope of the present invention.
Embodiment 1:
The present embodiment is for a 110kV transformator:
This Transformer Abnormal Oil Chromatography, the 1st, 2,3 grades, 35kV side D.C. resistance are abnormal, other tests are normal.
According to method disclosed by the invention: (1) first carries out state evaluation to equipment, D.C. resistance is abnormal to be needed to deduct points 30 points, determining foundation according to the device levels in subordinate list 1, this equipment is in abnormality, it should determining equipment operation maintenance strategy by (2) risk assessment further.
(2) risk evaluation results: the asset evaluation of equipment is 3, loss of assets degree is 2.45, probability of malfunction 0.650: value-at-risk is 4.78, and this equipment belongs to excessive risk equipment according to understanding to have the equipment Risk grade in subordinate list 2 to determine.Need to enter (3) life appraisal flow process.
