Based on the current problem of condition monitoring in auxiliary equipment of power plant, the prognostic system of the auxiliary equipment is researched. The system uses the modeling method of multivariate state estimation technique and similarity measure, the similarity of predicted value and actual value is calculated, then the auxiliary equipment working condition is determined. The result shows that the failure prognostic system can monitor the auxiliary equipment of power plant comprehensively and issues warning signs in the early failure.
