The utility model relates to a simulation training system for the operation and maintenance of a distribution network. The system comprises an operation desk, an operating handle, a pair of three-dimensional (3D) glasses and a computer device, wherein the operation desk is used for mounting and supporting each component of the system; the operating handle provides various operations for a trainee in a virtual environment; the 3D glasses are used for identifying a 3D image; and the computer device is used for receiving the operation triggering information of the trainee, feeding back the triggering information to a processor, and giving a response to a processing result through simulation software. The training method comprises the following steps that: the trainee enters a simulated scene of the system for tool selection operation, viewing angle switching operation and capturing operation, and the system judges whether the operation is accurate or not, generates an operation result of the trainee, and displays the operation result to the trainee through a 3D display. The trainee can select parameters of the simulation training system for the operation and maintenance of the distribution network for operation training in a simulated environment, so that the effect of improving the distribution network operation and maintenance operation capability of the trainee is achieved.
