摘要
借助提取主元的思路 ,在小样本情况下 ,用PLS方法对定子绝缘状态的非破坏性参量与其击穿电压之间的相关性信息进行筛选和综合 ,讨论了定子状态特征参量的各种数据信息。试验结果表明该方法在样本数较少及非破坏性参量之间存在多重相关性时 ,具有更好的分析解释能力 ,为定子绝缘状态参量分析提供了新的研究方法。
A new approach based on partial least square (PLS) is used in the study and analysis of the stator winding condition parameters. Based on the idea of extracting principal components, correlation information between the nondestructive parameters and residual breakdown voltage are screened and synthesized under the condition that only a few samples are available. Moreover, various data message of the stator winding condition parameters are also discussed. The experimental results indicate that the method can select and extract PLS components of condition parameters from sample data, and the problems of less samples and multicollinearity are solved effectively in regression analysis.
