| Abstract: | The basic principles and implementation processes of prognostics based on physic of failure (POF) are introduced,the method and implementation means of steps in POF technology are analyzed.According to the POF framework,a prognostics system is built for the real-time fault prediction of certain power monitoring unit.Experimental results show that the method is effective,and can be applied to practical engineering and model development. |
