摘要
电力变压器具有电能转换、传输和分配的作用,变压器故障能否准确诊断将直接影响到网供电可靠性和系统的安全运行。综述了几种常见变压器故障检测诊断方法,分析了各自优缺点,在此基础上介绍了一种新的故障诊断模型———仿生模式识别,对其原理以及与传统模式的区别进行阐述。最后认为变压器故障的有效预测和准确定位仍是今后的研究重点。
Electric transformer is provided with functions of electrical energy conversion, transmission and distribution and correct fault diagnosis of transformer is directly related to power supply reliability of power grid and safe operation of the system. This paper summarizes several common diagnosis methods for transformer fault detection and analyzes each merits and demerits. On the basis of this, it introduces one new kind of fault diagnosis model which is called bio-mimetic pattern recognition and states its principles and differences from other traditional modes. It considers effective prediction and cor- rect positioning of transformer fault will be research emphasis in the future.
