Automated hill chart modeling procedure to estimate the performance of double regulated units

François Avellan, Henri-Pascal Mombelli, Loïc Andolfatto

The work presented in this paper details an original procedure developed in order to automatically build on-cam surfaces for double-regulated hydropower units such as Kaplan or bulb turbines. The proposed method allows a sparse exploration of the operating ...
