LOAD CALCULATION & SUB-STATION DESIGN FOR ACADEMIC BUILDING-4,DIU ASHULIA CAMPUS

Abstract

To be a B.Sc. Engineer from Daffodil International University, We have to take a four credit course as EEE-499 (Thesis/project). For our graduation we have taken EEE-499 which is Project. Our Project title is “Load calculation & substation design for academic building-4, DIU Ashulia campus ” We have gathered practical knowledge about Substation, Sub-station Protection, Different types of Protective relays, Bus-Bar System, Sub-Station Installation, Layout Planning, Ring Main Unit (RMU),AVR, Busber Trunking system, Genarator, Power Transformer, Distribution Transformer, Instrument Transformer, Both CT, Isolator, Circuit Breaker, Fuse and Transformer ,Switchgear etc. Before doing this Project we had theoretical and practically knowledge about substation. But now we feel that we have gathered knowledge about this Equipment’s comparing to before. In sub-station section we saw the whole process step by step. We learnt how to test a Transformer, What the difference are between Transformer and Instrument Transformer we have also learnt the use of CT and the reasons of using CT at high voltage range. We have also strong knowledge about Substation switchgear HT, LT, PFI, Bus-bar Trunking system and the use of circuit breaker and especially Load Calculation.
