Wind-Solar Hybrid Streetlights

Abstract

The wind and solar energy are called green energies. They have many advantages and have become important newly arisen energy types. When using wind and solar energy alone, they greatly depend on the weather. But the wind-solar hybrid system can make up for this disadvantage, because it can effectively use the solar energy when daytime and summer, and the wind energy when night and winter.

The wind-solar hybrid system was designed in this thesis．This system uses an AC bus．It is permitted to enlarge the system and it can connect the other equipment conveniently. In the thesis it is also designed and analysed the configuration of the wind-solar energy system, the controller, and inverter.

The conclusion of this thesis is to show that the combination of wind and light energy can be effectively. It improves the use of natural resources. It is a good demonstration of the social sustainable development.
