一种变压器健康状态分析的方法和系统
摘要：
本发明提供一种变压器健康状态分析的方法，包括以变压器正常老化及绝缘运行作为健康指数分析目标，确定二者分别对应的权重赋值；在正常老化中，得到本体健康指数；在绝缘运行中，选择多个指标体系，根据预设的处理规则，得到所选各指标体系的健康指数及对应的权重值，并根据绝缘运行的权重赋值，得到所选各指标体系的新权重值；计算正常老化的权重赋值与本体健康指数乘积，及计算绝缘运行所选各指标体系的健康指数及其对应的新权重值的乘积，并将计算出的多个乘积累加的和值作为综合健康指数。实施本发明，能够提高变压器健康状态评估、缺陷诊断的准确性和可靠性，为智能电网智能决策及分析提供信息支撑和技术基础保障。
摘要（英）：

The invention provides a transformer health state analysis method which comprises the following steps: regarding a normal aging health state and an insulation operation health state of a transformer as health index analysis targets, and determining weight assignments of the two correspondingly; in the normal aging state, obtaining the health index of the transformer body; in the insulation operation state, selecting a plurality of index systems, obtaining the health index of each selected index system and the corresponding weight values according to a preset processing rule, and obtaining a new weight value of each selected index system according to the weight assignment of the insulation operation; and calculating the product of the weight assignment of the normal aging and the health index of the transformer body, and calculating the product of the health index of each index system selected under the insulation operation state and the corresponding new weight value, and regarding the sum value obtained by accumulating the plurality of calculated products as a comprehensive health index. The method can improve accuracy and reliability of health state assessment and defect diagnosis of the transformer, and provides information support and technological base guarantee for intelligent decision and analysis of a smart power grid.
