Aimed at the defect of simulation supporting system development in the past, this paper introduces a design base on chained list structure thought to build primary connection chart taking 0n topological structure ,and lays emphasis on design principles and implement method.

Based on the current development of domestic training simulator for substation, this paper systematically analyzes the functions of simulation supporting platform for substation, and then proposes some design methods, such as the hierarchical model and the storage with the chained list structure, which makes the graphic system reusable, opening and extensible.

A list structure is introduced,which contains two flags.

The paper applies a table data structure of suface table, ring table, vertex table to describe 3 D graph, discusses an algorithm and key technology of transferring 2 D screen coordinates to 3 D coordinates, and solves any interactive cutting display technology of 3 D graphical vision.

The Ant Colony Optimization is used to search the solution space,with the means of two-dimension link structure,although progressive decomposition of the packing space to loading many kinds of rectangular packing objects,and the effective coding and decoding method is given.
