摘要： A system for controlling the flow of turbined water from a plurality of hydroelectric plants arranged in series along a watercourse with an open channel flow, defining upstream of each plant, a plurality of head races subject respectively to hydraulic flow and level constraints. The flow of water turbined by each of the plants is controlled by a flow setpoint. The system includes regulation of a global electrical production power set-point for the plurality of hydroelectric plants by a flow regulation setpoint taking into account the flow setpoint of each of the plants. The flow regulation setpoint determined by the regulation is weighted for each of the plants by weighting coefficients as a function of the respective hydraulic characteristics of the head plurality of races.

摘要： Disclosed herein is a novel method for operating a hydropower reservoir which is an improvement over the existing single-parameter (the current month) USACE Rule Curve approach, the improvement comprising the consideration of a second parameter, namely the water level of the reservoir at the beginning of the month, in the decision-making process for operation of the reservoir.

摘要： A turbine system that can be releasably anchored in a flow of liquid, like a waterfall, and generate power from the flow includes a runner operable to receive some or all of the flow of liquid and rotate to generate power, a penstock operable to direct some or all of the flow toward the runner, and an intake operable to direct some or all of the flow into the penstock. The runner may be coupled to a generator to generate electric power. The penstock has a length that is adjustable to accommodate changes in the height of the liquid drop or waterfall, which may be desirable if the distance between the top and bottom of the drop fluctuates like an ocean's tide. The turbine system also includes a valve operable to modify the flow of the liquid flowing into the runner, and a control circuit operable to determine an amount of liquid entering the penstock and, in response to the determined amount, move the valve to increase or decrease the flow of liquid into the runner. In addition, the turbine system includes an anchor to releasably hold the system in the flow of

摘要： 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.

摘要： In a control system for a hydroelectric power station system including upper and lower water reservoirs connected through a water channel, an intermediate water reservoir having a smaller storage capacity than those of the upper and lower reservoirs and provided on the water channel in cascade with the upper and lower reservoirs, and two power stations disposed between the upper and intermediate reservoirs and between the intermediate and lower reservoirs, respectively, the control system is arranged such that the water level of the intermediate reservoir is detected continuously and the detected value of the water level is used to correct the load instructions which are applied to the power stations for controlling outputs of the power stations whereby the water level of the intermediate reservoir is maintained substantially constant, while the power generation of the power stations is controlled so as to satisfactorily meet with the load instruction applied to the power system.

摘要： A method for stabilizing the rotation speed of a machine with S-characteristics is provided. The method includes calculating a target net head and a target opening to affect guide vanes of the machine, the target net head and the target opening being calculated so that the torque exerted by water flow on the turbine is null and that the machine rotates at a target rotation speed; determining a real net head to which the machine is subjected; comparing the target net head with the real net head; and adjusting the opening of the guide vanes so as to converge towards the target opening and reduce a height difference between the target net head and the real net head.
