CHAPTER-1

INTRODUCTION

1.1 History

Increasing transmission distance and capacity is always the motivation to advance power industry technologies . In the history of the ac transmission system, increasing distance and capacity mainly depends on raising voltage level of transmission lines. At present, the highest voltage level of the ac power transmission line in operation is 750 kV. To further upgrade, the voltage level encounters difficulties of material and environment issues. The high-voltage direct current (H ....etc

Q.1: What is meant by electric current?
Ans. The flow of electrons.

Q.2: What are A.C. and D.C. currents?
Ans. Alternating current (A.C.) changes its direction with a definite frequency. The direct current (D.C.) flows in one direction only.

Q.3: What is meant by frequency?
Ans. Number of vibrations per sec.

Q.4: What is the frequency of A.C. in Nepal?
Ans. 50 cycles/s.

Q.5: What types of waves are produced in the thread?
Ans. Transverse stationary waves.

Q.6: What kind of vibrations are produced in the thread?
Ans. Forced ....etc

Electricity often travels over very long distances to reach urban load centres. For example, the distance between Baie-James region where water from the Grande Rivi re ends up after driving the turbines in eight power stations and Montr al is about 1,000 kilometres as the crow flies. However, the farther electricity must travel, the greater the risk that part of it will be lost on the way. Since utilities invest heavily in the high-volume transmission of power over long distances, they take special steps to limit these transmission losses.W ....etc

pOWER TRANSMISSION THROUGH FRACTIONAL
FREQUENCY SYSTEM


ABSTRACT

The fractional frequency transmission system FFTS is a very promising long -distance transmission approach, which uses lower frequency (50/3) to reduce the electrical length of the AC power line, and thus its transmission capacity can be increased several fold . This paper introduces the primary experiments results of FFTS.

The experiment uses the phase-controlled cycloconverter as the frequency changer, stepping up 50/3Hz electricity to 50Hz electricity and ....etc
