write different ways to improve an existing over head a.c power transmission system

Homework Answers

Answer #1

1) for transmission and distribution, we prefer high voltages because the power is constant at the generating station and load centre.

2) when ever we increase the voltage then current flowing through the conductor is reduced. So power losses i.e copper losses are reduced. So the efficiency of the system improved.

3) for increasing the voltage at the generating station we use step up transformers.

4) by improving the voltage at the load centre, we will connect FACTS devices.

5) by improving the power factor at the load centre, we will connect phase condensers across the load centre.

. 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...

Consider data transmission between two computers in different geographical locations. Data is transmitted in ‘blocks’, that is, in fixed-length sequences of digits. Suppose that the transmission may be routed over any one of three different routes, the selection being made automatically by a route selector according to existing traffic conditions, every time transmission of a block is initiated. Transmission takes place over the three routes various fractions of the time, as follows: Route A: 60% of the time Route B:...

You must design a power transmission system to connect a DC motor to its load. The motor is given in the motor catalogue as a BM1400 motor. You must create a transmission that will connect to this motor and have a two stage gear reduction (i.e. there must be two sets of gear reduction) with a total drive reduction of 10:1. The final output shaft must be at 90 deg from the input shaft. You must specify all the components...

A monopoly has a lot of power over an industry and one of the ways it controls power is their average total cost curve may fall through such a large range of output that smaller firms cannot compete and in fact this could be the case where a single firm is able to supply a product over such a wide range of output to basically satisfy total market demand and not experience rising average costs. What kind of barrier to...
