Abstract: A power generation device is a primary excitation variable speed pumped-storage power generation device or a primary excitation variable speed power generation device. When an output of a pump turbine or a water turbine is insufficient for a power output equivalent in a vicinity of a fully opened guide vane opening and the rotational speed decreases, an increase in a generator motor output command or a generator output command is stopped, and the stop of the increase in the generator motor output command or the generator output command is canceled after the rotational speed is increased.

Abstract: A hydro-electric power system includes two containers and a support beam having two ends, each end holding one of the containers. The ends allow the containers to travel along a length of the support beam. The support beam pivots about a pivot point, giving each container a maximum height and a minimum height. Fluid flows into each of the containers when located near their maximum height, the flow of water weighting each container and causing it to descend, each container moving longitudinally outward from the pivot point along the support beam as it descends. A dumping mechanism causes each container to release fluid near its minimum height, each container ascending after releasing water and moving longitudinally inward toward the pivot point along the support beam.

Abstract: A method of controlling power provided by a generator to an end system in which power is diverted from the output of said generator to an auxiliary system during periods of excessive power output from the generator. The diverted power is stored in an energy store and, during periods of lower power output from the generator, is returned to the end system by discharging the energy store. The diversion and return of power is controlled to maintain the power delivered to the end system at a desired mean power level. Diversion of power from the generator also has the effect of preventing the generator from producing excessive voltage levels.

Abstract: A control system for synchronous condensing operation of a hydroelectric turbine-generator wherein the draft tube water level for the turbine is controlled through the use of that generator's power or current consumption. Either parameter may be used in the process. Water impacting the turbine will increase both of these parameters above an optimum minimum value. Either a generator power or current device provides a signal to a control circuit. When the signal from either device exceeds a preset value, the control circuit injects compressed air into the turbine cavity until the signal returns to its optimum value.

Abstract: A hydrokinetic turbine system with dynamic tuning capabilities is disclosed. Individual hydrokinetic turbine units are dynamically tuned to accommodate changes in height and flow velocity corresponding to water in a waterway. Dynamically tuning the turbine units to accommodate waterway changes optimizes power generation output. Dynamically tuning a turbine system includes raising or lowering turbine blade height, extending or retracting turbine blade length, and narrowing or widening a turbine mouth, channel, and exit through which water flows. The hydrokinetic turbines may be arranged in an array along a waterway, and each hydrokinetic turbine in the array is connected over a controls system configured to adjust turbine characteristics at each turbine unit in the array for optimizing power generation output for the waterway in which the turbine array is installed.

Abstract: A power generating system including a movable tank filled configured to move vertically, a piston driven by the movable tank via a piston rod, a first cylinder filled with the liquid, and connected to the piston at a top end and a turbine at a bottom end, wherein the piston reciprocates in the first cylinder pushing the liquid from the first cylinder into the turbine causing the turbine to rotate and produce power, and a stationary tank connected to an outlet of the turbine. The system further includes a second cylinder connected to the movable tank and the first cylinder, and a balloon filled with gas connected to a top portion of the movable tank, wherein the balloon lifts the movable tank from a bottom position to a top position when the movable tank is empty.
