Using the dispatcher training system(DTS) to train the dispatchers is an effective way to improve their operations. This paper presents the structure and important modules of DTS for substation. The 3D technology is introduced to make the simulation more comprehensive and vivid, so, the system gets more complicated, the data exchange mechanism is introduced in detail. Besides the main module, some other function modules are also introduced to make the system more flexible and convenient. This system can be well used in the other substation of the same type. The design idea can also be used for other training system for reference.
