Analysis of Distribution System of Dhaka Power Distribution Company Ltd. (DPDC)

Abstract

The study summaries the work performed in the study “Analysis of Distribution System of Dhaka Power Distribution Company Ltd. (DPDC)”. Dhaka Power Distribution Company Ltd. (DPDC) is responsible for distribution. Thus, are using equipment Transformer, circuit breaker, Lightening arrestor, current transformer, potential transformer, Auxiliary transformer, relay, isolator, fuse etc. We also acquired a clear understanding of the different distribution system equipment. The study work assigned to us was to design a 132/33kv substation and a 33/11kv substation. We considered the incoming power at 132kv and the power transferred to the main bus through the isolator-circuit breaker-isolator combination. Power from the main bus was fed into a 20/28MVA transformer, which lowered the voltage to 33kv. The power is then fed to two busses of 33kv, from which different loads have been tapped. We have learned a great deal in our internship at DPDC and have acquired practical knowledge to help us in future. The study will then be submitted to our mentor for verification.
