Abstract

The invention relates to a semi-physical simulation device and a simulation method of a ship gas turbine generator set. The device and the method solve the problems that the simulation accuracy of the existing gas turbine generator set is low and the risk in the test process is high. Aiming at the need of simulating the ship gas turbine generator set, on the basis of the traditional computer digital simulation, by adding partial physical devices, a simulation system is enabled to get closer to the running state of a real generator. At the same time, by using the device and the method to simulate the ship gas turbine generator set, the debugging quantity for the test of the real generator can be greatly reduced, tests which cannot be conducted in a real generator state can be conducted, the test expenses are saved and the test safety is increased. The device and the method are suitable for the semi-physical simulation of the ship gas turbine generator set.
