摘要:
电力变压器是电网电力输送中的核心电气设备,合理评估变压器的性能对保证电力系统稳定运行意义重大。文中根据变压器故障的原因和评价指标来源,提出了基于定量修正层次理论的变压器性能评估方法。针对变压器性能评估指标体系中评价因素结构复杂、数量庞大的问题,首先依据指标体系中反映变压器故障的准确程度,筛选出能够反映变压器绝缘性能、油性能、过热性故障和放电性故障的关键指标,建立了变压器性能评估关键指标体系;其次利用层次分析法并结合定量修正评分函数,确定指标的最优权重,得到各指标的评分值,有效抑制了主观因素对性能评估的影响;最后选取两台不同电压等级的变压器为实例进行性能评估,验证所用方法的合理性和实用性。
Abstract:
The transformer is the core equipment of the power system, and it is of great significance to reasonably evaluate the performance of the transformer. Based on the causes of transformer faults and the sources of evaluation indicators, this paper proposes a transformer performance evaluation method based on quantitative correction hierarchy theory. Aiming at the complex structure and large number of evaluation factors in the performance evaluation index system of transformers, firstly, according to the accuracy of the transformer faults reflected in the index system, the key indicators that can reflect the insulation performance, oil performance, overheat fault and discharge fault of the transformer are selected. The key index system of transformer performance evaluation is established. Secondly, the analytic hierarchy process is combined with the quantitative correction scoring function to determine the optimal weight of the indicators, and the scores of each indicator are obtained. The influence of subjective factors on performance evaluation is reduced. Finally, two transformers of different voltage levels are selected for performance evaluation to verify the rationality and practicability of the method used.
