| Summary: | 碩士 === 大同大學 === 機械工程學系(所) === 96 === To make the problems of energy lacking and global warming better, people should positively develop clean and renewable energy like wind power and solar energy. Some huge wind turbine systems which can be connected with power supply systems have been introduced into Taiwan. To do justice to these systems, or to develop new wind turbine systems which are more appropriate for civil wind, it is necessary to train people to have sufficient understanding of the characteristics of wind and to have the ability to develop new wind turbine systems. So our lab planned to develop a battery charging system with small wind turbines. The system will be appropriate for using in Taipei city, i.e. can start in the breeze, and its size will be appropriate to be demonstrated in education field. Then this system can be used to train people for developing wind turbine systems.
Aiming at the purposes of demonstrating in education field and helping teaching, we have developed and tested a battery charging system with small wind turbines, which has the following characteristics: 1.The wind turbines are four-bladed. 2.The revolution radiuses are both 0.5m. 3.The wind turbine can start in the breeze of 2m/s velocity. 4.The system will start to charge a 6V battery after the wind velocity is up to 4m/s. 5.The charging system can basically protect batteries from overcharging. This system contains four parts, a high speed propeller type horizontal wind turbine, a battery charging system, an output power measuring and recording system, and a gyromill type vertical axis wind turbine. According to the test result, this system is appropriate for operating in Taipei city, and can be demonstrated in education field by industrial electric fan. It fits in with the goal of designing.
