Research Status and Trends of Ultra-Low-Head Water Resources and Hydro-Turbines

Zhang Yuquan,Zheng Yuan,Sun Ke,Yang Chunxia and Luo Hongying

Strategic Study of CAE 2018, Volume 20, Issue 3,   Pages 90-95 doi: 10.15302/J-SSCAE-2018.03.013

Abstract:

China is rich in hydropower resources, and hydropower technology development is the first choice to increase the supply of renewable energy, optimize the energy structure, and alleviate environmental problems. This paper focuses on rich microhead resources in China and presents the demand and application characteristics of microhead resources such as rivers, canals, reservoirs, power plant tailings, piped water supply, municipal wastewater, and marine energy. The paper summarizes two types of microhead hydro-turbines suitable for open and closed watersheds, which provide a basis for the design method of microhead hydro-turbines and the study of their flow characteristics and mechanism. This paper introduces the research trend of microhead resource evaluation and hydropower turbines. In addition, some suggestions for future research are put forward.
