Electric Power Generation from Low Head Simple Turbine for Remote Area Power Supply

Abstract

Over recent years, there has been an explosive growth of interest in the development of micro-hydropower generationturbine based on low head. Initial investment in building huge dams and large power stations is needed for high head turbine, beside these large dams are not environment friendly. Particularly in lower head, screw turbine is suitable for environment reason where this turbine has high efficiency, relatively lower cost and low environmental impact. Screw turbine can be applied in remote area which has water resource and no grid connection available. This paper reports experimental results examining the relationship between rotation speed and power. Laboratory scale of screw turbine is made by using locally available materials. Test results show that different speed of generator caused by different diameter of pulleys has great discrepency.
