Abstract:

In recent years, voltage instability has been a big issue in power systems. There are many factors contributing to voltage collapse which might cause blackouts, such as the demands of consumption growth, the influence of harmonic components and reactive power constraints. These factors are very difficult to predict in real environment. High-voltage transmission lines are an important part of the power system. As the operation of the power grid expands, the demands on long distance transmission lines will increase. These lines are often exposed to large diverse geographical areas with compl

Abstract:

Transmission line parameters play a significant role in a variety of power system applications. The accuracy of these parameters is of paramount importance. Traditional methods of determining transmission line parameters must take a large number of factors into consideration. It is difficult and in most cases impractical to include every possible factor when calculating parameter values. A modern approach to the parameter identification problem is an online method by which the parameter values are calculated using synchronized voltage and current measurements from both ends of a transmission l

Abstract:

The introduction of synchrophasor technology to the realm of power systems has presented a myriad of novel approaches to age-old problems. In this thesis, the questions of instrument transformer calibration and transmission line parameter estimation have been examined. With synchrophasors offering real-time data for analysis, a solution to each individual problem seems feasible. A quandary however arises due to the fact that calibration methods depend on accurate knowledge of line parameters, and estimation of these parameters depend on calibrated measurements.

Abstract:

Renewable energy is playing an increasingly significant role in power system operation and stability assessment with its numerous penetration expansion. This is not only brought by its uncertain power output and inverter-based equipment structures but also its operation characteristics like Low Voltage Ride Through (LVRT). It is thus necessary to take these characteristics into consideration and further to find more adaptive schemes to implement them for more effective analysis and safer power system operation. All the aforementioned is based on the accurate identification of the system fundam

Abstract:

Effects of a magnetic field on the double-probe technique are studied experimentally by means of symmetric floating computer controlled fast double probes in low and intermediate pressure plasmas. In addition, the effects of the magnetic field on the electron temperature, electron density, and electric field have been investigated. As it is expected, when there is no magnetic field, properties of the discharge plasma are best described by Langmuir theory. Whereas, when there&rsquo<br>s a magnetic field of sufficient strength Schottky&rsquo<br>s theory of ambipolar diffusion applies.

Adsorption refrigeration is one method of using waste heat/solar thermal power to generate cooling. However, the current performance of adsorption chillers needs to be improved. The key to optimising the design of the chiller is to understanding the adsorption parameters for different working pairs.

Based on measurements of capacity and adsorption rate coefficient, parameters used in the design of the chiller like the length of the fin, the thickness of the adsorbent bed a
