摘要

以确保电力系统稳定运行为目的，研究基于光谱分析的电压互感器运行状态研判方法，提升运行状态研判效果。激光拉曼光谱检测平台依据拉曼散射原理，获取电压互感器绝缘油拉曼谱线强度，按照拉曼谱线强度，绘制电压互感器绝缘油拉曼光谱，完成电压互感器内绝缘油拉曼光谱数据采集；通过迭代多项式拟合算法，预处理电压互感器绝缘油拉曼光谱；利用主成分分析法在预处理的拉曼光谱内，提取电压互感器绝缘油拉曼谱线强度特征；利用核Fisher判别分析法，建立电压互感器运行状态研判模型，在该模型内输入拉曼谱线强度特征，输出电压互感器运行状态研判结果。实验证明：该方法可有效采集电压互感器拉曼光谱，并预处理拉曼光谱；该方法可有效提取拉曼光谱特征，完成电压互感器运行状态研判；在研判不同类型运行状态时，该方法研判的Kappa系数均较高，即研判结果与实际结果间具备较优的一致性。

Abstract

For the purpose of ensuring the stable operation of power system

the operational status assessment method of voltage transformer based on spectral analysis is studied to improve the assessment effectiveness of operational status. The laser Raman spectrum detection platform acquires the Raman spectrum line intensity of insulating oil of voltage transformer based on the principle of Raman scattering

and the Raman spectrum of insulating oil of the voltage transformer is plotted in accordance with the Raman spectrum line intensity strength so to achieve the acquisition of Raman spectrum data. The Raman spectrum of insulating oil in voltage transformer is preprocessed through an iterative polynomial fitting algorithm. The Raman spectrum intensity characteristics of voltage transformer insulating oil are extracted from the pretreated Raman spectrum by principal component analysis. The kernel Fisher discriminant analysis method is used to set up a model for assessing the operational status of voltage transformer. The Raman spectral line intensity characteristics are input into the model and the operational status assessment result of voltage transformer is output. The experiment shows that the method can effectively collect the Raman spectrum of voltage transformer and preprocess the Raman spectrum. The method can effectively extract the Raman spectrum characteristics and achieve the operational status assessment of the voltage transformer. In case of assessment of different types of operational status

the Kappa coefficients assessed by the method are high

namely

the assessment results have better consistency with the actual results.
