介绍了一种基于HMM的电力变压器故障诊断系统软件的设计与实现,给出了HMM建模和分类设计的步骤。在该系统中,利用Visual C#和LabVIEW为工具开发上层软件,利用COM技术实现算法的模块化。该系统可及时掌握电力变压器的工作状态和故障征兆及发展趋势,进行超差报警和故障诊断,以保证输变电系统的安全运行。
The design and realization of HMM-based power transformer fault diagnosis system software is introduced in this paper, and the steps of HMM modeling is discussed.This software system developed in Visual C# and LabVIEW.and arithmetic is modularized by COM technology.This system can timely hold the work state of the power transformer and give a alarm in bad state,then fault diagnosis is carride out to insure safe run of power system,
