Energy management for optimal renewable energy usage in an apartment building

Kodithuwakku GR [Thesis-Full-text]

Common renewable energy plants with proper energy management for a selected community can bring immense benefits to its consumers compared to isolated/individual renewable energy (RE) systems. Optimal usage of RE within ...
Assessment of energy losses in single phase energy metering in Sri Lanka

Jayawardana TMNP [Thesis-Full-text]

Sri Lanka has achieved almost 100% electrification at the end of the year 2017. The total number of consumer accounts adds up to 6.76 million and out of that about 6 million are single phase consumers in the tariff categories, ...
Improvements to maintenance and operation practices to achieve better reliability in distribution network

Chandrasekara GC [Thesis-Full-text]

With the growing concerns on depletion of fossil fuels and enhancing demand for green energy the need of an alternative source of energy has arose. As a replacement to fossil fuel driven engines and machineries, electrically ...
Use of electric vehicles as a quick response energy storage : case study for Sri Lanka

Bambarawane LSN [Thesis-Full-text]

With the fossil fuels depleting, the non-conventional energy sources is taking the wheel I the field of electricity generation. Yet, their inconsistencies owing to reliance on intermittent energy sources such as wind and ...
Three phase state estimation techniques for network voltage unbalance assessment

Manmatharajan, S [Thesis-Full-text]

Voltage unbalance is an important aspect of power quality. Unbalance can damage power equipment in a power system network, affect the operation of sensitive customer equipment and increase losses. Conventional Power system ...
Design of an optimum power solution for telecom base sites

Amarakoon, GM [Thesis-Full-text]

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 ...
Design of the power feeding system for electrified railways case study: Panadura -Veyangoda railway sector

Thotagamuwage, S [Thesis-Full-text]

In railway systems, electrical traction is more efficient, comfortable and more economical than diesel traction. Since the railway transportation is a major public transportation means in Sri Lanka, having an efficient and ...
