在电力系统中,电力变压器扮演着至关重要的角色,其绝缘老化状态直接影响电网运行的稳定性。本书共4章,全面地阐述了油浸式电力变压器老化状态检测的试验方法,所介绍的试验方法高效且前沿,既包含最直接有效的国标法(黏度法)检测绝缘纸聚合度、通过检测油中溶解糠醛含量间接检测变压器老化状态,也包含最具效率的基于拉曼光谱技术的检测方法;还介绍了对不同检测方法的诊断技术,如主成分分析(Principal Components Analysis,PCA)、支持向量机(Support Vector Machine,SVM)、神经网络以及经遗传算法、粒子群算法改进后SVM和神经网络算法。当前,国内针对变压器老化状态的书籍介绍内容集中在变压器油的性能指标、变压器油的老化和污染、变压器油中溶解气体产生机理等方面,未有系统性介绍老化状态检测与诊断技术的书籍。本书填补了针对变压器老化状态检测与诊断技术方面资料的空白,可作为相关领域研究人员的参考资料,也可供技术人员培训使用。
