Abstract
The Kansas stations show power densities of from 175 to 200 W/m2 at a
height of 25 ft. Using the 3/7 power law, a 200 W/m2 power density would increase
to 360 W/m2 at a height of 100 ft and to 490 W/mZ at 200 ft. There appears
to be an increase in power toward the southwestern corner of the state.
Confirming this is the very high power density at Dalhart, Texas of 337 W/m
at an assumed 25 ft which scales to an extremely high 820 W/m2 at 200 ft. However,
the Dalhart data cannot be considered reliable since little is known about
the station and data is available over only a five year period. It does seem
reasonable to assume that power densities of at least 500 W/m2 at a 200 ft
height are available in the southwestern part of the state. It is possible
that areas exist with even higher power densities and it is almost certain that
there will be individual sites with higher energies available, since the NWS
station locations are not usually selected with high wind velocities as a consideration.
The Kansas stations and Dalhart show energy direction distributions dominated
by winds from the south and north and it seems clear that siting should
consider enhancing the winds from these two directions.
The La Junta, Colorado wind distribution differs considerably from the
other stations, presumably because it is further west. It is not known if a
sudden change in wind characteristics occurs with western movement or whether
the change is gradual, but it seems evident from this data and from other publishes
data that the wind energy decreases in Colorado when compared with that
available in the western half of Kansas.
Further investigation will consider the study area in more detail. An effort
will be made to determine if there are areas with considerably higher wind
energies than those at the stations considered here and to locate individual
sites with higher energies. A search will be made for more wind data in the
southwestern part of the state and an attempt will be made to select individual
sites from maps of the area. A measurement program may then need to be undertaken;
the necessity for measurements will probably depend on the amount of
existing data which can be located.
