At present, the early design of the substation project still adopts the traditional manual design method. The electrical secondary design needs to be carried out according to the substation electrical main connection diagram and electrical general layout diagram provided by the electrical primary design. The electrical secondary designer checks the project scale, interval construction period (current construction or long-term reservation), primary equipment layout, secondary equipment room setting, etc. based on the electrical main connection diagram and electrical general layout diagram, and then carries out the secondary equipment configuration, secondary device cabinet assembly and secondary panel cabinet layout. The manual design efficiency of this scheme is low, and the design quality depends on the ability level of the designers. In addition, the electrical primary design and electrical secondary design schemes often do not correspond after the scale and scheme are modified and adjusted many times, resulting in design errors.
