Semi-physical real-time closed-loop test system for tidal current energy generator set control system

The invention discloses a semi-physical real-time closed-loop test system for a tidal current energy generator set control system. The semi-physical real-time closed-loop test system comprises an impeller and transmission chain simulator based on RT-LAB, a tidal current energy generator set factory test prototype and a tested control system. The impeller and transmission chain simulator based on RT-LAB simulates impeller torque and transmission chain motion characteristics, performs signal interaction with a tested control system through hardware wiring, and interacts the generator speed obtained through simulation to a tidal current energy unit factory test prototype. IO signals of all subsystems of the tidal current energy unit factory test prototype directly interact with the tested control system; the tested control system is a control system which is actually put into use on site and is connected with the RT-LAB digital simulation system. The comprehensive digital real-time closed-loop test on the functi
