CHAPTER 1 1.1 INTRODUCTION Load frequency control (LFC) or Automatic generation control (AGC) is an emerging issue in electric power systems. The objective is to maintain the system frequency and the power exchange between the areas within specified limits‚ irrespective of sudden change in load. The prime mover governing system provides a means of controlling power and frequency; and this function commonly called Load Frequency Control or Automatic Generation Control. The automatic load

Installing the UPFC makes it possible to control an amount of active power flowing through the line. Simulations were carried out using MATLAB and PSCAD software to validate the performance of the UPFC.

Abstract-In this we use a piezoelectric crystal which gives variable voltage output depending upon the vibrations given on the crystal surface. This voltage is converted to current using suitable converter. Now the current is passed through a memristor‚ which has a corresponding resistance value. Whenever the current increases‚ the resistance value increases and the change in resistance is detected using a microwave generator connected at the end. Using the microwave level‚ an external device (similar

conversion. That same modem can receive incoming audio-frequency tones that were transmitted from the twisted pair telephone line‚ and convert those tones into the defined levels of digital signals. If an analog-to-digital converter is positioned after a digital-to-analog converter‚ within a communications circuit‚ the digital signal output will be identical to the digital signal input (Rouse‚ 2005). An analog signal may also be improved by using an analog-to-digital conversion method. The analog

The measuring scales and radar sensor is used for measuring the amount of material in the silo. In order to avoid bringing a lot of dust‚ concrete mixer must also be equipped with air filter and automatically remove dust in the air by using vibration

Everyone has a favorite athlete that they admire watching as they grow up. But my favorite athlete is a athlete that I was never able to see play. His name is Vincent Edward Jackson better known as Bo Jackson. He was born on November 30‚ 1962 in Bessemer‚ Alabama. Jackson came to fame as a multi-talented athlete‚ who excelled in baseball‚ football and track at an early age. His superior athletic abilities memorized me in ways that no other athlete has. He had a body of a Greek God and a personality
