To solve the costly, time-consuming and unscalable problem of previous substation 3 D simulation system, a new 3 D visual component assembly technology of smart substation simulation is put forward. The visual component includes the 3 D model of the smart substation's equipment, and the realization of the equipment's logic function and IEC61850 communication module's simulation. With the assembly of visual component, the 3 D design of a smart substation can be accelerated. In addition, the whole substation'...
