Aiming at improving the stability and safety of the power generating equipment,reducing the unnecessary economic loss due to the unplanned downtime of the power plant which caused by generating equipments failure. Failure prognostic and condition monitoring system for equipment was introduced to power plant. By comparing the differences between real-time data and the expected value based on historical normal data of the equipment,the possible state of the equipment was estimated,and the signs of equipment failure could be detected before the failure happened. The application of the system on Taizhou Power Plant showed its usefulness for operational staff and equipment managers.
