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 electri ....etc

INTRODUCTION
Ball valves are most widely used valves for flow control in fluid flow lines for wide range of temperature changes (-200°C to 500°C).Most of the outlet valves of chemical plant storage were installed with ball valves for sudden closing and opening purposes. For petroleum and chemical plants it is very convenient to operate with ball valves.
Ball valves are used in situations where tight shut-off is required. The type of seat can vary with the valve pressure rating and m ....etc

ABSTRACT
Wide band Sigma-Delta PLL modulator is based on PLL fractional N synthesis techniques along with Sigma-Delta modulation to randomize fractional N spurs. A modified Sigma-Delta function allows for suppression of Sigma-Delta noise at low frequencies & hence allows wider bandwidth. This is achieved using a fractional-N PLL architecture. They are capable of synthesizing frequencies at channel spacings less than the reference frequency. This helps to increase the reference frequency & hence reduces PL ....etc

ABSTRACT
UWB is a wireless technology that transmits binary data”the 0s and 1s that are the digital building blocks of modern information systems. It uses low-energy and extremely short duration (in the order of pico seconds) impulses or bursts of RF (radio frequency) energy over a wide spectrum of frequencies, to transmit data over short to medium distances, say about 15”100 m. It doesn™t use carrier wave to transmit data.
