Utility distribution system

a single two-transformer substation will be used to supply the transportation hub  the substation will be fed initially from one of the 138 kV lines  when the transportation hub load reaches 35 MW, the second 138 kV line will be tied into the substation  the 230 kV line will not be used to serve the transportation hub 1. Start your project by developing a year-by-year load forecast for the first 10 years of the transportation hub. Start the load at 10 MW in year 1, growing to 50 MW in year 10. Assume a load factor for each year. Assume an uncorrected power factor of 85% lagging. 2. Develop a plan for power factor correction. Show the plan projections year by year. 3. Draw a map showing the layout of your primary feeders. Assume a feeder loading of 10 MW to be “fully loaded.” Decide how many feeders need to be built initially, and develop a plan showing when new feeders will be needed. Also show ties (normally-open connections) between the feeders. Specify the devices used to tie the feeders together. 4. Show the design of a typical secondary circuit. Specify the load per secondary circuit. 5. Assuming a demand cost of $10/kW and an energy cost of $0.06/kWh, select a service transformer to use based on the evaluation method
