Cavitation detection device, cavitation detection method, and cavitation detection program

摘要

A cavitation detection device that detects the occurrence of cavitation in the liquid storage unit 2 in the power plant, and the information storage means 50 that stores the measurement data of the pressure gauges 10 and 20 and the measurement of the inflow pressure gauge 10 from the normal data The model construction means 60 for constructing a model by extracting the correlation between the data and the measurement data of the outflow pressure gauge 20; the correlation extracted from the correlation extracted by the model construction means 60 and the measurement data of the pressure gauges 10 and 20; A cavitation detection device comprising: cavitation detection means 70 for detecting a disruption of relationship as the occurrence of cavitation.
