110V universal battery charging panel using pic microcontroller

Vijithananda, SK [Thesis-Abstract]

Conventional power electronics and electronic control circuits have been replacing by the intervention of the microprocessors/microcontrollers in modern industrial applications. This is mainly because with their applications ...
A Conceptual design for a tower type concentrating solar power plant near Hambantota

Wijayawardhana, NABR [Thesis-Full-text]

In this study the basics of a central receiver type solar thermal power plant including a thermal storage are studied. Further, the technical feasibility of a central receiver type solar thermal power plant near Hambantota ...
A dynamic load shedding scheme for maintaining system frequency stability with the increasing renewable energy penetration

Herath BHMST [Thesis-Abstract]

Renewable energy power plants, especially grid connected solar and wind generation units are displacing the conventional generator stations with rotating machines with inertia. In Sri Lanka, renewable energy generation has ...
A Mechanism to reduce waste due to voltage dips in narrow fabric looms

Gamini, HKL [Thesis-Full-text]

Like any other industry, apparel industry too tries to minimize their product cost by reducing production waste. Voltage fluctuations and power failures are two of the most concerning factors affecting the production. Even ...
A Neuro-fuzzy controller for efficient operation of water pumping system

Nishantha, MGS [Thesis-Abstract]

The need for energy conservation is increasing the requirements for increased levels of electric motor & pump efficiencies. Controlling motor speed with load change has proven very successful in many applications such as ...
A Novel behavior based mobile robotic platform for landmine detection

Aravinthan, A [Thesis-Abstract]

Humanitarian demining is an urgent and necessary activity to be carried out to resettle in places where the civilians were used to live before the war. Humanitarian mine clearance technology currently used in various parts ...
A Real time traffic signal control system

Jayakody, ANNK [Thesis-Full-text]

Traffic congestion problem in Colombo city is getting worse since traditional traffic control system could not fulfill the need. Since the existing system is a fixed time fixed cycle control system, it cannot fit with ...
Achieving frequency stability through controlled active power injection using energy storage systems

Aluthge CD [Thesis-Abstract]

As solar Photovoltaic solar generation increases in the power system the conventional generators are being replaced or lose their dominance. Therefore, the resultant inertia of the system reduces. Due to this reason, in ...
Acoustic design optimization of close-fitting enclosure using genetic algorithm tool for diesel power generator soundproofing application

Ehelepola, I [Thesis-Full-text]

Network providers are faced with significant challenges in delivering backhaul solutions. Given that solutions based on Time Division Multiplexing (TDM), is not providing improved efficiency at a reasonable cost. Thus the ...
Active current shaping for better utility interface

Perera, MHC [Thesis-Full-text]

Increased use of nonlinear electrical loads injects harmonic currents to power systems. High levels of power system harmonics create voltage distortion and enlarge power quality problems. Harmonics result in poor power ...
Active vibration suppression with disturbance force estimation

Abeysiriwardhana, WASP [Thesis-Full-text]

Vibration is a basic phenomenon that has attached control engineering’s attention for many decades. Vibration rejection in control systems is implemented with passive, semi active and active vibration suppression systems. ...
Adaptive vision attentive robot eye for service robots in domestic environments

Madhusanka, BGDA [Thesis-Full-text]

Using eyes as an input modality for different control environments is a great area of interest for enhancing the bandwidth of human machine interaction and providing interaction functions when the use of hands is not ...
An Advanced machine learning approach to estimate the state of charge of battery energy storage system for micro-grid

Jeewandara JMDS [Thesis-Abstract]

Microgrids and energy storage systems play a major role in the sustainable and clean energy sector. There are various types of energy storage systems (ESS) are available and among them, battery energy storage systems ...
Agent based metering system for energy networks

Ranawaka, DMD [Thesis-Full-text]

Centralized automated single server based energy meter reading systems required high-end resources, at the same time it has low efficiency benefits, low reliability and real time meter data monitoring get more complex when ...
Alternative power supply options for safe shutdown of Lakvijaya power plant in a total blackout

Priyantha, GWV [Thesis-Abstract]

Lakvijaya Power station with a capacity of 300MW is designed to deliver generated power to national grid initially over Veyangoda transmission lines. But there is no other auxiliary power supply from the grid. In addition ...
Alum and lime dosing controllers for water treatment plant

Hettiarachchi, LP [Thesis-Full-text]

Many techniques are applied to the control of Alum and Lime commonly termed as coagulant dosing in a drinking water treatment plant. Coagulant dosing rate is non linear con-elated to raw water parameters such as turbidity, ...
An AC drive system to replace an existing DC drive system

Muhandiram, RRN [Thesis-Full-text]

DC commutator motor is the oldest motor but still the best performance motor. It has control simplicity and control accuracy although commutator motor has some inherent drawbacks due to its mechanical commutator. Normally, ...
Analysing of power quality problems of wind power generators

Chandranath, MLAA [Thesis-Abstract]

Wind power as a rule does not contribute to voltage in grids. Also, wind power very often is a source of voltage fluctuations and flicker. Furthermore, care must be taken to upkeep availability of networks more or less ...
Analysing of voltage surges in grid substation auxiliary supply

Hemaratne, JDKG [Thesis-Abstract]

In Sri Lankan National Electricity Grid, severe voltage fluctuations have been noticed in the Grid Substation auxiliary supply. The auxiliary supply is quantitatively 20CkVA, but very important to keep in good health because ...
Analysing the maximum wind power penetration level around Kalpitiya Peninsula

Kothalawala, TR [Thesis-Full-text]

The Government of Sri Lanka has declared the importance of developing renevvable energy in line with the national policy of maximizing indigenous sources and ensuring fuel diversity. Sri Lanka has exploited hydropower ...
