Influence of Head Loss on Optimal Operation of Small Hydroelectric Plants

In order to make optimal operation calculation of small hydroplant more accurate and rational, head loss of hydroelectric plant with complex diversion system is analyzed in this paper. Illustrations proved that different unit commitment probably leads to great difference of head loss. This difference should not be simplified and neglected. This paper presents a general method which is suitable for optimal operation of small hydroelectric plants. The method can be used to optimal operation of similar plants.
