The study of 2 jets turgo turbine performance and it design for rural area in Thailand

Abstract

The study of 2 jets turgo turbine performance and it design for the area which far from transmission line system in Thailand was performed to obtain water turbines with a simple model and with good performance appropriate to manufacture in local. This study was conducted at the san-mai village scale hydropower project, Mae Chan District, Chiang Rai Province. (The Village Scale hydroelectric project has been built for develop rural area. The villager has to be participating in the construction of weir, Head race, Penstock, Powerhouse. The finished power plant was operating in the co-operation form. The village scale hydroelectric project was limited to 0-200 kW. 30 Year pass, all project were operated well for support the village activity. However, The Cross flow turbine which used in the project has low efficiency and not strong enough for the heavy duty operation. The purpose of this research was developing the 2 jet turgo type turbine.)  With the capacity of 25 kW, The Project condition is 47 meters net head, 80 liters per second of water flow. 300 millimeter Pipe diameter, 1,100 meters pipe length. The control system is Electronic Load Controller. The manufactured turbine has 85 % efficiency. Corrosion resistance and can support for the heavy duty operation.
