Secondary Equipment Placement Strategy Considering Grid Layer Constraints of Screen Cabinets

Modularization is in line with the development trend of smart substations. However, research on the systematic analysis of the influencing factors of smart substation modularization is still lacking. This paper systematically analyzes the influencing factors of smart substation module division from the perspectives of function, space, time, cost and the whole life cycle. Afterward, from the perspective of substation construction cost, the placement of the secondary equipment in the panel cabinet is analyzed, and the corresponding mathematical model is established with the optimization goal of minimizing the number of panel cabinets. Our model can provide the solution with the greatest space utilization on the premise of ensuring the same function as the secondary equipment screen cabinet.
