Analysis of bulk consumer demand for tariff design

Gunaratne, DH [Thesis-Abstract]

Bulk consumers are the main revenue generating category of the electricity consumer mix in Sri Lanka. Their contribution has a large impact on demand in the power distribution network. The tariff applied, the metering ...

Analysis of surface flash over of 33 kV insulator due to saline pollution

Janaka, NHC [Thesis-Full-text]

Ceylon Electricity Board (CEB) has the responsibility of Transmission, most of the Generation and Distribution of electric power in Sri Lanka. Contamination-driven insulator failure is a problem that incessantly plagues ...

Analysis of transient overvoltage in medium voltage distribution network of Ceylon Electricity Board

Weerawardena, WAV [Thesis-Full-text]

This thesis presents the analysis of transient overvoltages in medium voltage (33kV) network and the research is based on feeder lines in the Uva province. Parameters which influence lightning performance of overhead ...

Application of 'Line Drop Compensation' to improve voltage of 33 kV distribution network

Gamage, SRK [Thesis-Abstract]

Leanthy Medium Voltage lines are typical in Rural Electrification implementations. The voltae of ends of such lines varies drastically from the time of peak loading to mid-night owing to drastic difference i line loaing ...

Automatic load balancing for distribution transformers

Fernando JHKA [Thesis-Abstract]

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 ...

Consideration of losses in determining solar PV penetration level in distribution networks

Nishshanka RMMP [Thesis-Abstract]

When it was realized that the conventional energy sources which powered up the industrial revolution are on depletion, a sudden awakening occurred in the field of renewable energy, during the latter part of the last century. ...

Designing an earth electrode for distribution substations

Samarasekara, PPB [Thesis-Full-text]

In electrical engineering, the term ground or earth has several meanings depending on the specific application areas. Ground is the reference point in an electrical circuit from which other voltages are measured, a common ...

Development of a neuro-fuzzy system for condition monitoring of power transformers

Sellahannadi, JR [Thesis-Abstract]

Well-being of Power Transformers is crucial to the reliable operation of a Power System. They represent a high capital investment in a Transmission Substation while being a key element determining the loading capability ...

Development of an intelligent outage management system to improve the reliability of electricity distribution network

Gunawardhana, CAA [Thesis-Full-text]

The thesis presents the result of pilot project that creates an intelligent outage management System which accurately locates faults in real-time and send fault details to the relevant maintenance crew. Several measures ...

Development of hybrid power system controller for mobile telecom base stations

Liyanage, MK [Thesis-Abstract]

Most of the telecom base stations are sited at elevated locations to get best signal propagation. If the area is isolated and away from the national grid of commercial power, it will involve higher capital investments for ...

Development of UAV based aerial observation platform to monitor medium voltage networks in urban areas

Ranasinghe DH [Thesis-Abstract]

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 ...

Evaluation and improvement of lightning performance of pole-mounted transformers and medium voltage (MV) distribution lines

Nanayakkara, DAJ [Thesis-Abstract]

This dissertation presents the means to evaluate lightning performance of pole-mounted distribution transformers and Medium Voltage (MV) distribution lines. The main intention is to provide a general bench-mark procedure ...

Impact of the embedded generation on distribution loss minimization

Sumanasekara, RMSMB [Thesis-Full-text]

Demand for Electricity has been increasing rapidly over the last decade and the cost of electricity generation too has been increasing due to the adverse impacts on hydro resources. Electricity loss reduction is a main ...

Investigation of supra-harmonics emission due to solar PV inverters

Ganege HC [Thesis-Full-text]

The number and rating of power electronic systems interfaced to electricity distribution networks have been rising at residential, commercial, industrial and utility environments over the last few decades. Domestic roof ...

Optimal reinforcement proposals towards loss reduction in the distribution network

Mohamedsabry, MM [Thesis-Full-text]

Network losses represent a major cost in the delivery of electrical energy. As such they need to be carefully managed. Economic and environmental concerns compel a major focus of attention on any such waste of energy. A ...

Optimizing the use of breaker switched capacitors in CEB systems

Dompege, DDU [Thesis-Full-text]

Ceylon Electricity Board (CEB) as many other utilities uses breaker switched capacitor banks for voltage support and reactive power compensation in grid substations. At present it has a 320Mvar installed capacity and 70Mvar ...

Security study of proposed distributed generators in Polonnaruwa
