Automatic load balancing for distribution transformers

Fernando JHKA [Thesis-Full-text]

Automatic load balancer is power electronic based equipment that balances the unbalanced current in the distribution transformers. This is achieved by employing an AC /DC/AC bidirectional current controlling system. The ...
Nine switch inverter to recover voltage disturbances of sensitive loads while feeding solar energy to the grid

Rathnayaka MVCP [Thesis-Full-text]

Electricity consumers have to mitigate voltage disturbance to ensure proper functionality of their sensitive electrical loads. Dynamic Voltage Restorer (DVR) has recognized as an effective and comprehensive power electronic ...
Development of UAV based aerial observation platform to monitor medium voltage networks in urban areas

Ranasinghe DH [Thesis-Full-text]

Electricity supply outages in urban areas in developing countries like Sri Lanka has a significant impact on the social life as well as the country’s economy. Owing to aging of network assets, the frequency of system ...
Experimental study on behavior of MOV based surge arrestors under distorted supply voltages

Illangakoon IPS [Thesis-Full-text]

Surges due to lightning and various switching operations are a common phenomenon in electrical power systems. Due to surges, there can be transient overvoltages in the lines as high as many times the normal supply voltage. ...
Neural network based inflow forecasting for optimum pond operation of a run-of-river type hydro plant

Wimalaratne MHD [Thesis-Full-text]

The current practise of pond operation of Upper Kotmale Hydropower Station is studied, where management of the pond is by subjective judgements of the operator. Accurate and reliable inflow forecast makes up an important ...
Development of a cost optimized LV distribution system employing the polygon - based planning

Wijendrasiri HKGM [Thesis-Full-text]

Network planning is a critical task in an electrical utility. A network should be capable of suppling the demand continuously with minimum disturbances. The responsibility of the network planner is to ensure a reliable ...
Designing of railway electrification network configuration to minimize power quality issues : a case study for proposed Sri Lankan railway electrification

Mendis, WUK [Thesis-Full-text]

Electrified railway system is a better solution for the rapidly increasing congestion of traffic in urban areas and railway transportation has many advantages compared with other modes of land/air transportation. In ...
Effect of residential solar PV penetration on distribution network protection schemes

Sanchala, IDS [Thesis-Full-text]

Electricity generation from solar PV has been increasing due to many reasons including heavy environmental considerations, reduction of burning fossil fuels, fast developments in the solar technology and the industry, ...
Enhanced orthopedic drill for bone surgery with haptic interface

Illangarathne, NC

Nowadays novel technology adoption is popular among the biomedical research areas. This research explores a way of improving precision, robustness, and accuracy of orthopedic surgeries. Orthopedic dills and saws are handheld ...
Automated demand response for a commercial building : a model design and pilot study

Fernando, CTJ [Thesis-Full-text]

The inherent intermittency of non-conventional renewable resources has been the major impediment in admitting renewable resources to the traditional Electricity Grid. The flexibility of loads in the power system are ...
Design of an optimum power solution for telecom base station sites

Amarakoon, GM [Thesis-Abstract]

The amount of power required to operate the telecom network is getting much higher depending on the size of the system deployed at the base stations. This may exceed a couple of kilowatts, occurring a high electrical and ...
Defining of normalized load profile curves for domestic customer groups to estimate feeder power loss

Jayawardhana, HACH [Thesis-Full-text]

‘Estimation of load profiles for domestic customers’ is a multi-purpose activity and ‘Estimation of daily feeder power loss' is only a one use of customer load profiles. In a country, domestic electricity customer percentage ...
Short term solar irradiance prediction model using ground based sky imaging

Samarakoon, KS [Thesis-Full-text]

With the growing energy demands and depleting fossil fuel deposits world is moving towards renewable energy. Solar energy has become a focus on this transition, especially in tropical countries where solar power harvesting ...
Feasibility of scheduled running of existing mini hydro power plants

Hettiarachchi, YSK [Thesis-Full-text]

The Electricity system load profile of Sri Lanka has a high evening peak demand and as a result has a low load factor. The load curve has a close relationship with the human behavior and other economic activities of the ...
Determination of optimum unit capacities of future coal power plants in Sri Lanka

Perera, APA [Thesis-Full-text]

In Sri Lanka, future generation plan includes number of coal power plants according to Long Term Generation Expansion Plan (LTGEP) prepared by Ceylon Electricity Board. Proportion of coal power generation is significant ...
Development of a state estimation algorithm for the electrical distribution system

Mahalaksha, MMHCN [Thesis-Full-text]

Over the past decade, the complexity of the electrical distribution network has been significantly increased. Power flow of the network has been changed from unidirectional to a dynamic scenario with the introduction of ...
Reactive power dispatch by distributed generators through step load flow simulation and genetic algorithm

Abeysinghe, AMGGSHB [Thesis-Full-text]

Demand for reactive power in a transmission and distribution network is met by various ways such as through power generating plants, compensation by means of capacitors at the utility grid and compensation at the load point ...
