Field Testing of Water Pumping Windmills by CWD (Consultancy Services Wind Energy Developing Countries)

摘要

Field testing of water pumping windmills is an important part of CWD's activities. Measurements are performed by means of Apple II computers are thereafter elaborated by means of the same computers, using software developed by the Wind Energy Group. The article discusses some aspects related to the hysteresis behavior of windmills driving piston pumps.
