The application of failure prognostic system in state monitoring of power plant generation equipments

Many equipments of power plant are always working in high temperature, high pressure and relatively harsh environment, it is easy to have failures. So it is necessary to make on-line monitoring. The failure prognostic system based on similarity modeling can detect early signs of equipment failure, thereby we can take measures online to restraint the deterioration development before the failure occur, reduce maintenance costs, and ensure the unit operation normally.
