FIELD: water engineering.
SUBSTANCE: invention refers to method and system of electric power generation when water levels in navigation locks change. Navigation lock uses hydraulic turbine and/or pump turbine for maintaining approximately constant value of flow velocities during water drainage through navigation lock within major portion of water transfer cycle, which leads to loss reduction of full head strength, and for recuperating unused hydraulic energy to be generated as electricity. Difference between water levels on the opposite sides of navigation lock forms the potential hydraulic energy. By controlling water drainage, full head energy losses are sufficiently reduced within this period, thus providing possibility of optimising hydraulic energy recuperation.
EFFECT: optimising hydraulic energy recuperation.
