State Evaluation for Power Plant Equipment Based on Deviation of Operating Parameters
In view of which the state of equipment cannot be obtained accurately in real-time, a new method of state evaluation is proposed in this paper. Through Fault Tree Analysis (FTA) and Failure Mode Effects and Criticality Analysis (FMECA), the impact of parameters on equipment state is researched and the deviation is defined to quantify the variation of the state of equipment. The evaluating model based on deviation is established and illustrated with an example. The studied case is about the state evaluation for rotor blade and the application proves the method to be effective in the state evaluation for power plant equipment.
