Optimal Design for the Run-of-the-River Plant System
Today, because of increasing energy needs and growing energy costs, it is necessary to exploit previously unexploited energy potentials with low ef f iency which exist in almost every country. A characteristic aspect of the water system in Yugoslavia is that there are numerous streamflows with gentle slope, which have been considered unsuitable from an economic standpoint for generating electric energy. But increasing costs of energy call for a new approach to such streamflows and arouse interest in their exploitation. Investigations show that the best solution for such streamflows is a series of run-off-the-river plants (RRP). Ihe relatively high costs of the construction of such structures result in a low degree of efficiency, and this means, that special attention should be paid to the maximum exploitation of water potential, i.e., to the optimal dimensioning of the system. Usually there are many different technical solutions (construction variants) for the construction of these structures, particularly if they are multi-purpose (e.g., if they can be used for flood protection, agriculture, recreational facilities etc., apart from energy supply).
