1000kva Substation Design and Load Calculation

Abstract

Our journey through the B.Sc. Engineering program at Daffodil International University. Our project title is "Load Calculation & Substation Design," which immersed us deeply into the intricacies of electrical substations and related equipment. Through this project, we transitioned from theoretical understanding to hands-on practical knowledge, significantly enriching our understanding of the subject matter. Delving into various facets of substation engineering, we meticulously explored substation safeguarding, various protective relay kinds, bus-bar systems, installation techniques, and layout design and essential components like ring main units, AVR, and switchgear. Our comprehensive study extended to power transformers, distribution transformers, and instrument transformers, where we not only grasped theoretical concepts but also engaged in practical testing methodologies. The project enabled us to differentiate between transformers and instrument transformers, understand the critical role of current transformers (CT) in high-voltage applications, and appreciate the significance of load calculation in substation design. Additionally, we gained proficiency in substation switchgear, including high-tension (HT), low-tension (LT) and power factor improvement (PFI) as well as the utilization of circuit breakers for effective power distribution and protection. Our journey through this project has been transformative, equipping us with a robust foundation in substation engineering and empowering us with practical skills essential for real-world applications in the field.
