Abstract:Based on Hefei Substation Project in Anhui Province, a new type of sail-shaped joint wire substation frame was designed. The layout of the wires was changed from the traditional horizontal arrangement to the vertical arrangement, which  greatly reduced the occupied area and cost. The artificial density method in the topology optimization of continuous structure was used to optimize the planar layout pattern of the sail-shaped frame. A new construction scheme of connecting plate for frame beam was put forward. According to the structural form and joint arrangement scheme, the finite element model was established by MIDAS/Gen and ABAQUS software to optimize the section type of circular steel tube, check its strength, stiffness and stability, and calculate and analyze the key joints of the frame. The results show that the sail-shaped joint wire substation frame is safe and reliable.

Keywords:substation frame; structural design; topological optimization; section optimization; joint analysis
