Pressure
Wind – what causes it?, cont.
Pressure differences cause the flow of fluids (gases and liquids)
pressure is always measured relative to some reference pressure
Sometimes relative to vacuum  absolute
Sometimes relative to atmospheric pressure

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
c ....etc

NON CONVENTIONAL ENERGY SOURCES
Abstract
The ever increasing rapid use of the fossile fuels day by day has threatened exhausting of conventional energy sources very soon. Also the use of conventional energy sources has increased the global pollution level which is resulting in climate change. Therefore time has come for searching altogether other sources of energy which are inexhaustible and gradually replace the conventional sources. The non conventional energy sources such as solar, wind, ....etc
