Design a Power Substation for Essar Steel Minnesota

Power substations are the important sections of any industry. Substations may be categorized as distribution, transmission, switching, or any combination thereof. In this multidisciplinary engineering project, which was offered by Essar Steel Minnesota, we designed a distribution power substation. A distribution substation is a combination of switching, controlling, and voltage step-down equipment arranged to reduce voltage to primary distribution voltage for different applications such as high power variable frequency drives. In this design, we investigated a number of engineering considerations such as building foundation, structure, building material, physical layout, grounding, equipment selection, cable trays, power fault analysis, safety, code and regulation. This substation will house approximately 20 medium voltage circuit breakers/switch gears, 9 transformers, and 7 medium voltage variable frequency drive units. Engineering safety analysis was performed to ensure that our design follows all codes and regulations
