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.
