Analysis of wind speed effect on voltage in wind power plant performance

Abstract

Utilization of new renewable energy has received special attention from the Indonesian government today because new renewable energy has several benefits from fossil energy, including environmentally friendly, non-polluting, abundant and will not run out throughout the ages. The growth of energy consumption is an average of 6.5 percent year, not yet balanced with sufficient energy supply, energy prices are increasingly expensive, energy subsidies are getting bigger, energy use is still wasteful. One way to overcome the problem of electricity is wind energy. Wind energy is a very abundant source of energy and there is no end of the year. At wind speeds of 1.5 to 3.0 m/sec, the voltage produced by wind power plants is linearly increased from 1.8 to 4.2 volts AC, from speed 3.0 to 4.0 m/sec, the voltage generated is in range from 5.0 to 6.5 volts AC. The DC voltage characteristic is equal to wind speed function. At wind speeds of 1.5 to 2.5 m/s, the voltage generated by wind power plants is linearly increased from 6.0 to 10 DC volts, from speeds of 2.5 to 4.0 m/sec the resulting voltage is stable 11 to 12 volts DC.
