monitor equipment through sensors. Continuous ...
Today with the developments in technology, expansion
and developments in industries, and increase in the standard of
living of the society, the demand for electricity keeps rising every
day. It is the responsibility of ...
Share of Non-Conventional Renewable Energy (NCRE), small hydro, wind, solar, bio-mass etc based electricity generation in Sri Lanka at present is 10% of the total annual generation. The Government of Sri Lanka has declared ...
This study examines the Sri Lankan generation planning practices and recommends several methodological changes and models to successfully integrate and evaluate Non-Conventional Renewable Energy (NCRE) resources in the ...
Congestion occurs on the nation’s electric transmission grids with the addition of new generation to meet the increasing electricity demand. Therefore, reliable, efficient and better quality of supply urge introduction of ...
The wide use of electrical induction motors in industries throughout the world requires, increasingly, more precision in fault diagnosis. Techniques of predictive maintenance such as Motor Current Signature Analysis (MCSA) ...
High wind penetration in a small power system can create overwhelming stability issues at contingencies. Hybrid wind and pumped-storage systems are widely adopted to harness the maximum wind energy potential locally. ...
Samanalawewa hydropower project includes a
reservoir, a water way system and a 120MW power plant as the
stage I development. Some provisions have been kept for stage II
development to add another 120MW power plant to ...
MicroGrid (MG) is a convenient solution to
integrate renewable energy sources to the existing power
network. Though ac MicroGrids are widely studied, researches
are focused towards the implementation of dc MicroGrids ...
Sri Lanka is located in an ideal position in the world map to harness more solar power compared to the countries situated away from the equator. Yet, Sri Lanka has been unable to gain the maximum advantage out of it due ...
Regenerative AC-AC converters are required for
serving AC loads that draw and return power during operation,
when input is also taken from an AC source. AC motor drives,
static VAR compensators, harmonic compensators ...
In developing countries, small vehicles such as three-wheelers are one of the most commonly used public transportation method and considered as an efficient way to travel in the traffic. Even though the commonly used type ...
