In the present era, power quality becomes the most important concern in electrical power
systems. This phenomenon has become an increasing concern to utilities and their
customers in the process of power delivery. ...
Through high voltage lines generating units are connected to load centers to form a power
system. The generated voltage steppes up before entering a transmission line, which
moves large amount of power over a long ...
In the 21st century, developing countries are still struggling with unreliable power
systems that are not smart and automated. Many researchers show that reliability of the
power system can be improved by using ...
This thesis presents design of fuzzy proportional integral derivative load frequency control
for multi-area power systems using particle swarm optimization. Area-1, area-2, and area-3 comprises Tana Beles, Fincha, and ...
Power has been and is the integral part of every walk of life in the modern human history. In the
event of power transmission to appliances, transformer plays key role. As with all, if not most,
electrical devices, ...
With the rapid evolution of the wireless technology feature and because the existing 4G
networks will be unable to satisfy the ambitious key requirements for future wireless
networks, it has strived to the development ...
The high bit rate of data is transmitted for longer distances by using Dense
wavelength division multiplexing. Dense wavelength division multiplexing is mainly
affected by the Stimulated Raman scattering effect ...
The continuous growth of load demand has risen the current drawn from the source,
voltage drop and power loss at distribution networks. In addition, the radial type
configuration of distribution systems with ...
Energy conservation and efficient usage are vital to the country’s development. Energy demand
is increasing globally due to the depletion of fossil fuel sources and other related issues.
Significant results can be ...
Power system is a large system which is very sensitive to damage and failure especially during
transmission line and power generating unit outage that is why contingency analysis is
performed to investigate the power ...
This thesis work presents assessment of power system harmonic problems on Kombolcha
Textile Share Company which is located in Kombolcha town about 337kms from Addis Ababa
towards north. The assessment identifies ...
A nation's ability to develop technologically, socially, politically, and economically
depends on a reliable supply of electricity. It is impossible to imagine modernization and
development in any field without a ...
Load demand forecasting is a key point in electric power system operation and planning.
It is used to determine the capacity of generation, transmission and distribution system. In
Ethiopian electric power system, the ...
The agricultural industry still relies heavily on manual labor and relatively little on technology.
Automation systems can help and enhance Ethiopia's agricultural sector in a variety of ways.
One of them is the ...
Air pollution in the world increase due to the emission of pollutant gas from vehicles. To solve
this problem electric vehicle with traction motor instead of ICE is the emerging technology
but speed control of traction ...
Due to the nonlinear characteristics of the valves and the interactions between the
controlled variables, designing a control system for coupled tanks is a difficult task. This
thesis deals with the comparative study ...
Robots, ranging from industrial pick-and-place robots to humanoid robots, are increasingly
being employed to accomplish activities that humans find tiresome and challenging.
Conventionally, they are driven by rotating ...
Induction motor is one of the most widely used machines in industrial applications like water
pumping system due to its high reliability, relatively low cost, and less maintenance
requirements. Indirect Vector ...
This thesis investigates the design and simulation of a robust trajectory tracking con-trol for autonomous underwater vehicle (AUV) using supertwist sliding mode control.
Autonomous underwater vehicles are submarines which ...
This thesis presents design and simulation of Artificial Neural Network based speed estimation of
induction motor using integer order (IOPI) and fractional order controller (FOPI) for control of
IM drives. Induction ...
