Development Of Algorithms For Security Oriented Power System Operation
(2009-07-23)
The objective of an Energy Control Center (ECC) is to ensure secure and economic operation of power system. The challenge to optimize power system operation, while maintaining system security and quality of power supply ...
A Peer To Peer Web Proxy Cache For Enterprise Networks
(2009-09-10)
In this thesis, we propose a decentralized peer-to-peer (P2P) Web proxy cache for enterprise networks (ENs). Currently, enterprises use a centralized proxy-based Web cache, where a dedicated proxy server does the caching. ...
Modeling, Analysis And Control Of Single-Phase And Three-Phase PWM Rectifiers
(2009-06-16)
Pulse width modulation (PWM) rectifiers are extensively used in battery charger, regulated dc voltage source, UPS systems, ac line conditioner and motor drives. The conventional control schemes for these rectifiers require ...
A New Family Of Soft Transition DC-DC Converters
(2009-09-10)
Switched mode power supplies (SMPS) have found wide spread acceptance in all power processing applications. The design demand is moving towards higher power densities. For reduction in size and weight, it is imperative to ...
Soft Switched Multi-Phase Tapped-Boost Converter And Its Control
(2009-08-04)
Boost dc-to-dc converters have very good source interface properties. The input inductor makes the source current smooth and hence these converters provide very good EMI performance. On account of this good property, the ...
Music And Speech Analysis Using The 'Bach' Scale Filter-Bank
(2009-08-13)
The aim of this thesis is to define a perceptual scale for the ‘Time-Frequency’ analysis of music signals. The equal tempered ‘Bach ’ scale is a suitable scale, since it covers most of the genres of music and the error is ...
Power System Data Compression For Archiving
(2009-07-23)
Advances in electronics, computer and information technology are fueling major changes in the area of power systems instrumentations. More and more microprocessor based digital instruments are replacing older type of meters. ...
Development Of Algorithms For Bad Data Detection In Power System State Estimation
(2009-05-12)
Power system state estimation (PSSE) is an energy management system function responsible for the computation of the most likely values of state variables viz., bus voltage magnitudes and angles. The state estimation is ...
Direct Time Domain Modelling Of First Return Stroke Of Lightning
(2009-05-21)
Being one of the most spectacular events in nature, lightning is basically a transient high current electric discharge in the atmosphere, which extends up to kilometres. Cloud to ground discharge is the most hazardous one ...
Receiver Channelizer For FBWA System Confirming To WiMAX Standard
(2009-09-10)
Fixed Broadband Wireless Access (FBWA) is a technology aimed at providing high-speed wireless Internet access, over a wide area, from devices such as personal computers and laptops. FBWA channels are defined in the range ...
