Description
technical field [0001] The invention belongs to the technical field of semi-physical simulation of a traction system, relates to a semi-physical simulation test system, in particular to a general semi-physical simulation test system of a traction system. Background technique [0002] Power electronics simulation technology has been widely used due to its high efficiency and safety. Semi-physical simulation is a simulation technology that connects the real object with the simulation model of the controlled object realized on the computer for testing. Part of the physical object is connected in the simulation. The hardware-in-the-loop simulation technology has developed rapidly because it is closer to the actual physical results. The physical object connected in the semi-physical simulation is usually the key component of the system. In the field of rail transit, the physical control unit of the traction system in the train traction system is the heart of the entire system, wh...
