Abstract

The invention discloses a multi-source information integrated total-amount state evaluation model of a power transformer. At present, a state evaluation model of power equipment has defects and disadvantages in the aspects including the data obtaining manner, part division, performance index setting and a scoring model, and the practical operation state of the power transformer cannot be reflected accurately and comprehensively in real time. According to a state evaluation frame of the power transformer, factors including power failure test, live-line detection, online monitoring, professional tour inspection and operation environment are combined, factors including the equipment state amount, adverse condition and family defects are rearranged, and the multi-source information integrated total-amount state evaluation model of the power transformer is provided. According to the invention, the problem in practical application of state detection data of the power transformer and the problem in scientific evaluation of the operation state of the power transformer are solved, scientific guidance is provided for onsite operation staff to make equipment maintenance strategies, and guidance basis is provided for state evaluation of other transformation equipment.

Description

technical field [0001] The invention relates to the field of power equipment state evaluation, in particular to a calculation model for evaluating and evaluating the operating state of a power transformer by applying multi-source monitoring data and operating environment data of a power transformer. Background technique [0002] On the basis of the statistical law of equipment operating status, the maintenance of power grid equipment has long adopted a combination of regular maintenance and fault maintenance. In many years of production practice, this maintenance mode effectively guarantees the safe and stable operation of the power grid. However, with the advancement of technology and the rapid development of the power grid, the regular maintenance method is more and more difficult to meet the needs of the development of the power grid. The rapid expansion of the power grid has also led to a sharp increase in the workload of regular maintenance, the shortage of maintenance...
