System and method for monitoring cavitation state of hydraulic turbine by fusing simulation and digital twins

Abstract

Disclosed in the present invention are a system and method for monitoring a cavitation state of a hydraulic turbine by fusing simulation and digital twins, which belong to the technical field of monitoring of hydraulic turbines. The present invention solves the problem that methods in the prior art have difficulty in predicting a cavitation state in advance, constructs a digital twin model by acquiring operating data of the hydraulic turbine, simulates the cavitation state of the hydraulic turbine, optimizes a data injection strategy based on a dynamic adjustment mechanism, generates optimization suggestions according to prediction results, realizes intelligent optimal control over the operation of the hydraulic turbine, and avoids faults of the hydraulic turbine caused by cavitation.
