100 MW of electrical power is delivered at 200 kV to a distribution center over a transmission line which consumes 10% of the total power developed by the generating station in heat losses.

a) What is the value of the voltage fed to the transmission line at the generator end?

b) How much power would be delivered to the same load if the resistance of the transmission line was halved but the generator voltage was unaltered?

A 100 MVA, 13.2 kV three phase generator (G) having a synchronous reactance of 10% is connected to a three phase Y-Y transformer T1 which feeds a 132 kV 10 miles transmission line having an impedance per phase of 2 + j5 ?/mile. At the receiving end of the transmission line is a Y-Y step down transformer T2. Three loads are connected to the secondary side of the transformer T2. Loads are as follows: Load#1 40 MVA at 0.8 pf...

DC and AC power distribution schemes are illustrated in the circuits below. Both are intended to supply customers with power at voltage V. zPowerGrid Consider an AC power grid with components like the circuit on the right. A transmission line that has a line resistor RT with a resistance per unit length of 4.80 ⨯ 10−4 Ω/m is to be used to transmit 5.00 MW over 400 miles (6.44 ✕ 105 m). The output voltage of the generator VS is...

. An Australian power transmission line is designed to deliver 100 MVA at 6.6 kV over a distance of 100 km. The total transmission line loss is not to exceed 2.5% of the rated line MVA. The magnitude of the leakage current due to the capacitive effect is 0.291 A. In this transmission system, you need to reduce this capacitive effect at least by 50%. In this situation, what type of compensation do you need? At the same time, you...

The National Electrical Code specifies safe current-carrying capacities for various sizes and types of wire. These ratings depend upon the length (“run”) of wire being used. For typical household use #12 AWG (American Wire Gauge) PVC-coated copper wire is rated at a maximum safe current of 20 A. The diameter of #12 AWG wire is 0.081”. At a current of 20 A find (a) the current density, (b) the electrical field strength, and (c) the potential difference for 25’ and...

Case Abstract: Company ABC, an AE, constructor and construction management firm, recently assigned Bob Ironside to turn a major coal fired generating station project around. Currently at 36 percent construction completion, the project is shifting from an emphasis on civil and structural work to bulk production. Cooperation of the owner, the multi-prime contractors, and strong labor unions is cach vital for performance improvement. The analysis of this project involves: 1) identification of significant external influences on the project organization, 2)...
