Abstract

The article shows that hydroelectric pumped storage plants reduce their efficiency when working un-der variable pressure. To solve this problem, it is advisable to transfer these hydraulic units to work at variable speed. An algorithm and a control system are introduced to allow maintaining the optimum effi-ciency of hydraulic units at lower head and respective speed.
