Introduction to Power System Protection
Power system protection systems have three basic components: Instrument transformers, Relays, Circuit breakers The function of the CT is to reproduce in its secondary winding a current I’ that is proportional to the primary current I. The CT converts primary currents in the kiloamp range to secondary currents in the 0–5 ampere range for convenience of measurement. The function of the relay is to discriminate between normal operation and fault conditions. The OC relay in Figure 2 has an operating coil, which is connected to the CT secondary winding, and a set of contacts. When |I’| exceeds a specified ‘‘pickup’’ value, the operating coil causes the normally open contacts to clos...
Monitoring of Power System Quality
Power Quality can be defined as the characteristics of the electricity at a given point on an electrical system, evaluated against a set of reference technical parameters. These parameters might relate to the compatibility between electricity supplied on a network and the loads connected to that network.The voltage waveform is normally distorted, and we have the so called Power Quality disturbances such as; voltage dips/swells, transients, harmonics and voltage unbalance amongst others. The study of Power Quality encompasses the Power Quality disturbances, as well as Power Quality standards, and Power Quality Monitoring.This project will tackle the subject of Power Quality, Power Quality Disturbances, Power Quality Standards as well as Power Quality Monitoring. A general description of each of the disturbances will be given, and the basic techniques which are used to mitigate that disturbance so as to improve the quality of the supply are presented.
Control of Flexible Alternating Current Transmission System (FACTS) for Power Stability Enhancement and Power Quality Improvement
The thesis will try to summarise the major power system problems and the important role of the FACTS devices to enhance the power system quality. Then, it will give a brief description for various FACTS and Active Filters controllers as mentioned on the existing publications. Most of the control schemes introduced in the existing papers were designed either for eliminating current harmonics or eliminating voltage flickers or for load flow control. So, this work is devoted to find a proper optimal control schemes for a system with series or shunt or series and shunt converters that can provide all functions together. Various optimal control schemes will be designed for systems with series, sh...
Real Stories of Academic Corruption in my Life
In this report, I will speak about the academic corruption I noted in some universities and academic institutions according to my experience with them. I will review also the abusive practices against me by some book publishing websites such as Ingramspark.com that arbitrarily closed my publishing accounts without reasons I will provide also a summary of the difficulties I encountered in electronic money transfer and online shopping due to the financial blockade against the Palestinians. The report will consist from the following parts 1. Academic Corruption in Higher Colleges of Technology in Dubai 2. Academic Corruption in University of Swaziland. 3. Some stories of corruption I met in Gaz...
Creating Wordpress Online Store and Wordpress Online Magazine
The objective of this work is to develop a Word Press Online Store with Different Ecommerce Plugins and Themes and Word Press Online Magazine with MH Magazine Theme The work consists of three parts: i. Part I: Building Personal Websie with online shop the sell Ebooks: The objective of this part is to develop a Ecommerce word press website with all commonly used Plug-ins. First I registered in some free webhost my domain http://hidaia-alassouli.000space.com Then I created the database and installed the word press package. I installed after that all important Plugins for my website. I tested different ecommerce plugin to sell ebooks .The report includes: 1- Changing the wordpress theme. 2- Cre...
