摘要
针对换流变压器结构复杂、难以对其进行精确状态评价的问题,提出了一种基于DHGF算法的换流变压器状态评价方法,建立了相应的评价指标集及对应的组合权重,给出了相关的白化权函数、权矩阵和评判矩阵,构建了完整的数学模型。运用DHGF算法对换流变压器的运行状态进行实例分析,得到了评估对象的状态等级和评分值。评价结果能较好地反映设备的实际状况,可为下一步的检修决策提供科学依据。
Aiming at the problems that the condition of converter transformer is complex and difficult to be evaluated accurately,a condition evaluation method for converter transformer based on DHGF algorithm is proposed. The evaluation index sets and the corresponding weights for converter transformer are established. The whitening weight function,the weight matrix and the evaluation matrix are provided. The complete mathematical model is established too. The real condition of a converter transformer is analyzed by using DHGF method,the condition level and the exact score are obtained. The results can reflect the real condition of a converter transformer,which can provide scientific basis for the future maintenance strategy.
