A Novel Technique For Enhancing The Pollution Flashover Strength Of Ceramic Disc Insulators
(2013-07-16)
Pollution is the single largest cause of transmission/distribution line outages, next
to lightning, which result in expensive power outages. A major significance of the
problem is that it can repeatedly occur even at ...
Studies On Silicone Rubber Nanocomposites As Weathershed Material For HVDC Transmission Line Insulators
(2013-06-17)
Outdoor insulators are one of the most important parts of a power system. The reliability of a power system depends also on the reliability of the insulators. The main functions of an insulator used for outdoor applications ...
Space-Vector-Based Pulse Width Modulation Strategies To Reduce Pulsating Torque In Induction Motor Drives
(2015-05-27)
Voltage source inverter (VSI) is used to control the speed of an induction motor by applying AC voltage of variable amplitude and frequency. The semiconductor switches in
a VSI are turned on and off in an appropriate ...
A Macroscopic Physical Model For Lightning Return Stroke
(2014-10-15)
In the design of most of the modern systems, lightning threat needs to be considered at the design phase itself. This demands a suitable model and owing to associated complexity, only simplified modeling have been attempted. ...
Reactive Power Planning And Operation of Power Systems with Wind Farms for Voltage Stability Improvement
(2017-09-23)
In recent years, the electric power industry around the world is changing continuously due to transformation from regulated market structure to deregulated market structure. The main aim of the transformation of electric ...
Studies on Electrical Treeing in High Voltage Insulation Filled with Nano-Sized Particles
(2018-03-08)
Polymers are widely used as insulating materials in high voltage power apparatus because of their excellent electrical insulating properties and good thermomechanical behavior. However, under high electrical stress, polymeric ...
Intelligent Techniques for Monitoring of Integrated Power Systems
(2018-02-10)
Continued increase in system load leading to a reduction in operating margins, as well as the tendency to move towards a deregulated grid with renewable energy sources has increased the vulnerability of the grid to blackouts. ...
A Networked Control Systems Framework for Smart Grids with Integrated Communication
(2018-02-28)
Over the last decade, power systems have evolved dramatically around the world, owing to higher demand, stringent requirements on quality and environmental concerns that are becoming increasingly critical. With the ...
Frequency and Time Domain Response Analysis of Transformer Winding for Indirect Measurement of Series Capacitance and Construction of Ladder Network Models
(2018-02-10)
This thesis proposes innovative methods to extract information embedded in the frequency and time domain response of the transformer winding, and utilizes them to suggest solutions to a few tasks that have until now been ...
