Abstract: The present disclosure provides a semi-physical simulation test bench and test method for a multi-machine parallel operation device of gas turbines. The gas turbines are all connected with gearbox shafts through SSS clutches, torque meters and couplers, and then a hydraulic dynamometer, an electric turbine dynamometer and a generator are independently or jointly driven through couplers and torque meters so as to charge a storage battery. Multi-shaft gearboxes comprise parallel operation gearboxes, and are connected with a bridging gearbox through couplers, electromagnetic clutches, supports, torque meters and couplers. The gas turbines can drive an electric dynamometer and the electric turbine dynamometer independently or cooperatively, so that the system has good operation characteristics under different working conditions. Meanwhile, the storage battery is additionally arranged, the flexibility of the test bench is improved, and the energy utilization rate is increased.
