Abstract | For water diversion projects, both the economic benefits from solving water shortage for water supply area and the effects on economy and environment for water source site should be highly valued. This paper analyzes the influence of diversion volume and selection of water source sites on the loss of cascade and parallel hydropower plants downstream and presents an optimization diversion scheme for the minimum energy loss based on the minimum ecological base flow of the water source site and the downstream river via a case study of Pingshang water diversion project in Shanxi province, China. The results show that energy output increases greatly with river runoff increase and energy loss cuts down as the volume of upstream diversion reduces. When water source site of diversion projects lies in the upstream parallel plants, optimal allocation of diversion volume depends mainly on distribution of the downstream power stations, the total installed capacity of cascade hydropower stations and the individual kinetic energy characteristics. The optimization diversion scheme of the project studied based on the minimum ecological base flow could cut down 13.7% of energy loss compared with the scheme that water diverted symmetrically from two parallel rivers. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
