The document summarizes the power distribution system for a city located between an industrial area and railway station. A 10 MW small hydro power plant was chosen due to topography and cost. Power is distributed through 4 substations to various areas of the city including 2 railway substations. The protection scheme and equipment used including transformers, circuit breakers and isolators are listed. A single line diagram shows the layout of the generation plant, distributing unit and substations along with feeders.
Design T&D of city
- 1. VIDWAAN Presented by: Gaurav Kumar Singh Aniket Kumar Satendra Dubey
- 2. Problem Statement Show locations and layouts of power plant(s) (type also), switchyard & local distributing unit, distribution / feeder lines, protection scheme for whole system along with proper ratings for the given city. Give a list of equipments (also give their numbers).
- 3. Given Layout of city
- 4. Location of Generation Plant: The Power Plant for the given city has been put up in the area between Industrial Area 1 and Railway Station 2 . Type of Generation Plant: A SMALL HYDRO Power Plant
- 5. The choice of the type of plant was decided by the factors as under: Topography of the area. Maximum Power demand of the city (Approx 7.48 MW). Cost Consideration. Pollution Factor. Judicious use of available resources.
- 6. Cost of generation is cheapest highest efficiency and highest project life amongst renewable . Sector Rs/kWh Efficiency (%) Project Life Small hydro 1.00–1.50 85-90 60 Wind energy 2.00–2.75 40 20 Solar PV 10.00–12.00 15 20
- 7. Maximum Demand Calculated is found to be 7.48 MW between 5 a.m. to 6 a.m. Plant Capacity Will be 10 MW. IT consists of 2 Generating Units of 5 MW Capacity for the reliable supply of power. Use of Bulb Turbine for Low Heads and Efficiency. About The Plant

- 10. Distribution System: Distributing Unit is used to supply the power to Industrial Area 1. Substation 1 is used to supply power Railway Station 2 & Railway Traction 2. Substation 2 is used to supply power to Rural Area. Substation 3 is used to supply power to Industrial Area 2, Business complex, Hospital, Railway Station 1 and Railways Traction . Substation 4 is used to supply power to School, Residential area, Street Lighting, Railway Station 1 and Railway traction. Two Railway Substations are used for the Traction Lines .
- 11. Position Of Sub Stations Substation 1 is taken near Power plant Substation 2 is taken for the Rural so near by it. Sustation 3 is taken near by Hospital since the availability of land. Substation 4 is taken near by School and Railway Traction And Station 1.
