Modeling of transmission tower grounding system

Karunapala, PMAU [Thesis-Full-text]

Performance of power transmission lines has a great impact on reliability aspects of a particular power supply system of a country. Unreliable power transmission lines can even leads to total power failures resulting with ...
Optimum reactive power compensation & voltage control using static var compensator for grid substations

Kumarasinghe, SCD [Thesis-Full-text]

As the volume of power transmitted in transmission lines increases, maintaining high quality and reliable power supply is required. Modern power systems sometimes operate with heavily loaded lines resulting in power system ...
Analysis of power quality issues due to the proposed solar power plants in Hambantota

Ratnasiri, M.D [Thesis-Full-text]

Solar power plants, despite their high initial investment are fast spreading in Asian countries owing to the availability of higher solar radiation throughout the day time. In Sri Lanka, two grid connected small scale solar ...
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. ...
Reaction torque observer based force feedback gripper with force lock

Ruwanthika, RMM [Thesis-Full-text]

Haptic information is a bilateral information of the law of action and reaction. Most of the researchers have done experiments on bilateral teleoperation but still they haven’t given much attention on force lock during ...
