Study on grid connection of the small horizontal axis wind turbine and network system SHIMIZU Yukimaru, OKAMURA Kiyoshi, TEI Den and YAMAMURA Naoki Abstract: The utilization methods of small wind turbine are two types. One of them is stand-alone type. Small electric power is charged to the battery system and the battery power is supplied to the light, TV, other domestic facilities and so on. Also, it is applied to the emergency facilities. Another one is applied to the Grid-Connection. The electric power is sold to the electric power company. In this case, high level quality of electric power is required. The quality of electric power is 60Hz0.5Hz, and so on. The voltage and current of supply power of small wind turbine must be regulated to the recognized value. The commercial power conditioner is applied to the variable output power of small wind turbine. The detail of the experimental results is described in this report. Keywords: Small horizontal axis wind turbine, grid connection to commercial net work system, power conditioner, data correction by network system 1. s/n 2. 2-1 LAN 2-1 2-2 2-3 2-4 2-5 PV-PN30G 2-1
