The study of stand alone wind generator system for small-scale radio base station

摘要

For the electric power Supply of the radio base station equipment in small-islands, power generators such as reciprocating engine has been used, and its maintenance have been necessary. The power supply system, which does not need maintenance operation is required. In this paper, it has taken up independent wind generator system, which technological innovation has been remarkable as a clean energy power supply system and it has examined its equipment scale by a simulation. Consumed electric power of the radio base station equipment was 3kw. The radio base station assumed that it was set in Yonaguni-jima suitable for the wind power generation. It is shown that the power system needs wind generation system of 5.3kw output, when stopping time of radio system by power cut is 1% in a year. It is also shown that this system needs the back-up storage battery of 49kWh.
