摘要： A power generator driving device utilizing tides to form a liquid piston comprises a fixed upside-down lid container, the container mouth is immersed in the seawater and the top end is higher than the highest sea surface while in the flood tide; and, at least one air pipe, having a first end pipe port communicating with the interior of the upside-down lid container and the other second end pipe port being defined above the sea surface, a rotating shaft of the power generator is configured outside the second end pipe port and the second end pipe port faces the windward side or the leeward side of the blade of the rotating shaft. The said configuration enables the seawater inside the upside-down lid container to form a liquid piston, and the liquid piston will gradually rise or fall accompanying with the flood tide or ebb tide of the seawater. Based on the communicating vessel principle, the air inside the upside-down lid container is squeezed by the seawater, such as the liquid piston to be blown out or suck in from the second end pipe port of the air pipe while in flood tide or ebb tide, thereby driving the blade to rotate to enable the power generator to generate electricity.

摘要： A seesaw-type hydroelectric power generation device is provided, including an elongated container (10), a hydroelectric turbine module (20), a pivot structure (30) below the elongated container (10), and a jacking structure (40) placed on both sides of the pivot structure (30). The elongated container (10) includes a first compartment (13) and a second compartment (14), and a water flow passage (15) connecting them. The hydroelectric turbine module (20) includes an impeller (22) and a power generator (21), the impeller (22) disposed in the water flow passage (15). When force is applied to the elongated container (10), it tilts around the pivot structure (30). The working fluid (WF) flows reciprocally through the water flow passage (15), driving the impeller (22) to rotate and thus generating electricity. The electricity required to drive the elongated container is less than the electricity generated, allowing for the continuous generation of electricity.

摘要： A converter for a wind energy installation and a method. The converter includes an inverter which drives a generator via a plurality of phases and an intermediate circuit having an intermediate-circuit voltage between an upper and a lower intermediate-circuit potential. The generator is driven with phase potentials at a variable frequency. A shift value is calculated between an extreme phase potential and one of the intermediate-circuit potentials, a separation value is determined between a middle phase potential and the closest intermediate-circuit potential, and an additional voltage is generated using the separation value as amplitude. The phase potentials are shifted through the shift value and the additional voltage is added to the middle phase potential. Accordingly, the switching elements in the converter do not need to be clocked in every second half-cycle resulting in reduced switching losses and increased current load capacity of the converter.

摘要： A multistage wind turbine or network of wind turbines with improved and optimized wind-directing, wind-shaping, and wind-power conversion features indicates that the shapes of these features directly affect the ability of the multistage wind turbine to use the power of moving air, such as wind, to spin a rotor and create torque on a rotor shaft to generate electricity. The wind-power-conversion mechanical efficiency described significantly improves upon previous designs by conversion of wind energy into electrical power at a superior price-to-performance ratio compared with existing alternative energy technologies.

摘要： The present disclosure is directed to a system and method for assessing farm-level performance of a wind farm. The method includes operating the wind farm in a first operational mode and identifying one or more pairs of wind turbines having wake interaction. The method also includes generating a pairwise dataset for the wind turbines pairs. Further, the method includes generating a first wake model based on the pairwise dataset and predicting a first farm-level performance parameter based on the first wake model. The method also includes operating the wind farm in a second operational mode and collecting operational data during the second operational mode. Moreover, the method includes predicting a first farm-level performance parameter for the second operational mode using the first wake model and the operational data from the second operational mode. The method further includes determining a second farm-level performance parameter during the second operational mode. Thus, the method includes determining a difference in the farm-level performance of the wind farm as a function of the first and second farm-level performance parameters.
