Analysis of wind velocity :-

I have analysis wind velocity in Rajouri region of Jammu ( Baba Ghulam shah badshah University Rajouri) for 30 days by a hand handling device known as "ANNEMOMETER" With ever  increasing  population  demand  of  energy  is  also  increasing  but  conventional sources  of  energy  such  as  coal,  petroleum  and  natural  gas  are  limited  and  will  not  last  in coming  future. So the  use  of  non-conventional  sources  of  energy  such  as  wind  energy,  solar energy  &  tidal  energy  will  increase  to  meet  the  increasing  demand  of  energy. Wind energy uses  kinetic  energy  of  the  wind. This kinetic  energy  can  be  used  to  produce  electricity  by using  flow  of  wind  through  wind  turbines  to  mechanically  powered  generators  for  electric power. The assessment  of  wind  resources  of  a  location  is  carried  out  to  determine  the viability  or  the  non-viability  of  a  wind  energy  project. The most  significant  parameter  which is  needed  to  be  considered  to  assess  any  wind  resource  is  the  wind  speed  as  the  wind  power project  mainly  depends  on the  magnitude  of wind velocity. A wind  turbine  is  a  device  that  converts  the  wind’s  kinetic  energy  into  electrical power. Wind turbines  can  be  used  to  generate  large  amounts  of  electrical  energy  in  wind farms  both onshore  and offshore. These wind turbines  can  be  classified  as: 1) Vertical  Axis  Wind  Turbine  (VAWT) 2) Horizontal  Axis  Wind  Turbine  (HAWT) 1.1.1  Vertical  Axis  Wind  Turbine:  The  vertical  axis  wind  turbine  is  an  old  technology, dating  back  to  4,000  years  ago. The rotor  of  the  VAWT  rotates  vertically  around  its  axis. Though it  is  not  as  effective  as  a  HAWT,  it  does  offer  benefits  in  low  wind  situations  where HAWT’s  have  a  hard  time  operating. It tends  to  be  easier  and  safer  to  build,  and  it  can  be mounted close  to the  ground and handle  turbulence  better than  the  HAWT. 1.1.2 Horizontal  Axis  Wind  Turbine:  The  horizontal  axis  wind  turbine  is  a  turbine  in  which the  axis  of  the  rotor’s  rotation  is  parallel  to  the  wind  stream  and  the  ground. Most HAWT’s today  are  two- or three- bladed, though some  may have  fewer or more  blades.

1.2 Wind Resources in Jammu and Kashmir  Jammu  and Kashmir is  considered to be  one  of the  best  zones  for micro  wind turbines. Jammu and  Kashmir  State  is  fairly  untapped  in  field  wind  energy  however  there  is  a significant  scope  of harnessing wind energy  in different  districts  if Jammu  and Kashmir State. The energy of wind mills  can  be  effectively used for water  lifting  and electricity  generation. '''Table.1.Wind Energy Potential  in different  districts  of  Jammu and Kashmir. S.no.
