Abstract:
A modified friction damper is presented to enhance the performance of conventional friction damper and semi-active variable friction damper. An additional plate is provided between the two sliding plates of a conventional friction damper which results in an additional sliding interface with the same normal (clamping) force. Similar modification is also made to semi-active variable friction damper (SAVFD) to enhance its performance. The enhancement in the performance of the benchmark building is studied under across wind loads ....etc

Abstract
Drilling assisted by axial vibration at low frequency is a promising machining process because, by naturally fragmenting chips, it can improve both productivity by canceling stripping operations and work piece quality by decreasing negative effects due to chip friction. Based on a theory of self-excited vibrations, a drilling device has been developed which is described in this paper. This technology is very compact and can used on any conventional machine tool. However the experiments on these machine tools are quite difficul ....etc

ENHANCED PERFORMANCE OF A DOUBLY FED
WIND-POWER INDUCTION GENERATOR AT WIND-
RANGE BOUNDARIES
ABSTRACT
The doubly fed induction generator (DFIG) is one of the largest generators used
with MW-class wind turbines. This paper focuses on the weak performance areas
of grid-connected DFIG-based wind turbines. Basically, the DFIG performance at
low wind speeds, close to the cut in speed, and around the full rating operation (in
the vicinity of rated wind speed) is investigated. For low wind speed region, the
causes of decreased efficiency ....etc

Doubly-Fed Induction Generator for Variable Speed Wind Energy Conversion Systems- Modeling & Simulation
Abstract The aim of this paper is to present the complete modeling and simulation of wind turbine driven doubly-fed induction generator which feeds ac power to the utility grid. For that, two pulse width modulated voltage source converters are connected back to back between the rotor terminals and utility grid via common dc link. The grid side converter controls the power flow between the DC bus and the AC side and allows the ....etc

INTRODUCTION


Wind turbines convert the kinetic energy present in the wind into mechanical energy by means of producing torque.
Large scale wind power projects are an attractive alternative to conventional capacity expansion.
In the present scenario , most wind turbine manufacturers now equip power generating units by induction generators.
They are operated either at fixed speed or variable speed.
Generators driven by fixed speed turbines can directly be conne ....etc
