The invention discloses a simulation training device and a simulation training method for switching operation of a power distribution circuit. The device comprises an operation platform provided with a fingerprint identifier, a touch screen and a three-dimensional display screen, wherein a handle and a start-up button are respectively arranged at two sides of the fingerprint identifier; a network interface is further formed below the side of the operation platform; and a three-dimensional signal emitter is arranged above the three-dimensional display screen. The method comprises the following steps of: logging in a switching operation simulation system, selecting a switching item and an own character, loading an operation scene, assigning a switching mission to teams, performing the switching operation, and giving out operation scores of trainers. The simulation training device and the simulation training method disclosed by the invention have the beneficial effects of reducing the training cost, achieving a good training effect, and improving the safety performance of the training.
