    Abstract: The invention concerns a system for controlling the flow of turbined water from a plurality of hydroelectric plants (1, 2, 3, 4, 5) arranged in series along a watercourse with open channel flow, defining upstream of each plant a plurality of head races subject respectively to hydraulic flow and level constraints, said plurality of hydroelectric plants, in which the flow of water turbined by each of said plants is controlled by means of a flow setpoint (QCui), said system comprising regulation of a global electrical production power setpoint (Pc) for said plurality of hydroelectric plants by means of a flow regulation setpoint (QRGP) taken into account by the flow setpoint (QCi) of each of said plants, and in that said flow regulation setpoint (QRGP) determined by said regulation is weighted for each of said plants by means of weighting coefficients (αi) as a function of the respective hydraulic characteristics of the head races defined upstream of said plants.

    Abstract: Method of regulating a water level of a dam installation having a plurality of turbine generator units arranged to generate electrical power, wherein at least some of the plurality of turbine generator units are arranged at least one of one above another and one beside another so as to form at least one turbine generator module. The method includes regulating, at least to some extent, the water level to a predefinable set point by starting or stopping at least one of the plurality of turbine generator units and adjusting, in discrete steps, a quantity of water which can flow through the dam installation, wherein a discrete step is defined by a quantity of water which can flow through a defined number of turbine generator units. This Abstract is not intended to define the invention disclosed in the specification, nor intended to limit the scope of the invention in any way.

    Abstract: A control apparatus responsive to the difference between liquid levels, and a method of controlling a liquid flow regulator by use of the apparatus is disclosed. The control apparatus may comprise a transducer responsive to the back-pressure maintained in a bubbler system including a pair of interconnected gas bubblers, one positioned upstream and one downstream of a flow restriction, such as a trash screen protecting the inlet to a hydroelectric turbine. The mouth of the downstream bubbler is positioned at a pre-selected elevation below that of the mouth of the upstream bubbler so that the pressure head of water at the mouth of the upstream bubbler sets the system back-pressure. When the downstream water level drops sufficiently below that of the upstream water level, the reduced water pressure head at the mouth of the downstream bubbler sets the system back-pressure. A flow regulator, such as a turbine wicket gate, is operated in response to the control apparatus.

    Abstract: Hydroelectric power generation systems and methods of using such systems are provided. A power generation system includes a reservoir that is at least partially defined by a plurality of precast segments. At least a subset of the precast segments are interconnected via complementary coupling elements. The reservoir is elevated with respect to a fluid supply. The system further includes a flow path providing fluid communication between the reservoir and the fluid supply, a power generation module configured to pump fluid from the fluid supply and into the reservoir via the flow path, and a power conversion module configured to convert kinetic energy of fluid released from the reservoir and travelling through the flow path into electric energy.
