Publication number: 20170145982Abstract: A submersible turbine generator unit can be placed in rivers, streams, or anywhere water flows in order to generate electricity without the need for dams. It is designed to work with its own diversion equipment for controlling and directing a flow of water into the turbine blades. The unit can be raised and lowered in the flow to enhance efficiency, respond to changing flow conditions, and for inspection/servicing, etc. The positioning system can use a motorized worm gear and a rack to raise or lower the turbine generator combination. Once raised up, a hard connection point allows attachment of a lifting cable so the turbine/generator combination can be easily removed and replaced as needed. A submersible turbine generator utilizes uniquely shaped turbine blades that efficiently engage flowing water and spin the turbine shaft without presenting undue risk to aquatic life.Type: ApplicationFiled: November 6, 2015Publication date: May 25, 2017Inventor: Barry G.

Publication number: 20170145983Abstract: The invention relates to an installation having at least one caisson positioned at a given depth in a marine environment, said caisson including a rigid tank in which an oscillating plate moves, said oscillating plate being adapted to oscillate in relation to a vertical axis depending on fluctuations in the height of the water column created by the swell perpendicular to the plate, said tank and plate defining a chamber. The installation is characterised in that the chamber is sealed by a flexible hermetic pouch which is filled with a gas and deforms according to the oscillations of the oscillating plate, the pressure of the gas inside the pouch being adjusted so as to compensate for all or part of the weight of the water column perpendicular to the plate in the absence of swell.Type: ApplicationFiled: June 30, 2015Publication date: May 25, 2017Inventor: Christian CARME

Publication number: 20170145985Abstract: A vertical axis hydrokinetic turbine apparatus comprises a drive shaft assembly, at least two blade assemblies, and at least two pairs of support arm connection interfaces. The drive shaft assembly comprises a rotatable drive shaft, an upper and lower center plates fixedly mounted to upper and lower ends of the drive shaft. Each blade assembly comprises a main blade having a longitudinally elongated body with a foil profile configured to produce lift in the presence of flowing water; and first and second support arms each having a longitudinally elongated body extending away from the main blade and terminating at a drive shaft connecting end. Each pair of support arm connection interfaces serve to releasably connect one of the blade assemblies to the drive shaft assembly and comprises upper and lower center plate components on the upper and lower center plates respectively, and support arm components on each of the first and second support arms.Type: ApplicationFiled: August 11, 2014Publication date: May 25, 2017Inventors: Peter Lyes, David Cocksedge

Publication number: 20170145986Abstract: A rotor blade assembly including a first blade section including a joint end and a custom fit second blade section including a joint end, and a method of fabricating the rotor blade assembly is disclosed. One of the first blade section or the custom fit second blade section includes an inner surface defining a cavity. The cavity is configured to receive the joint end of the other one of the blade sections in an overlapping configuration to define an overlapping region and a mating joint. A joining means is used to secure the joint ends of the blade sections. A profile of the outer surface of the custom fit second blade section generally corresponds to the aerodynamic profile of the first blade section such that a substantially continuous aerodynamic profile is defined between the blade sections when the joint ends are configured in the overlapping configuration.Type: ApplicationFiled: November 25, 2015Publication date: May 25, 2017Inventors: Peggy Lynn Baehmann, Shridhar Champaknath Nath, Shatil Sinha

Publication number: 20170145989Abstract: Systems and methods for controlling operation of one or more auxiliary circuits in a wind turbine system are provided. For instance, a grid event associated with the wind turbine system can be detected. In response to the grid event, a control signal can be provided to an auxiliary circuit breaker of the wind turbine system. The auxiliary circuit breaker can be associated with one or more auxiliary circuits that are not directly in a power production path of the wind turbine system. The auxiliary circuit breaker can disconnect the one or more auxiliary circuits from the grid based at least in part on the control signal.Type: ApplicationFiled: November 19, 2015Publication date: May 25, 2017Inventors: Allen Michael Ritter, Harold Robert Schnetzka, Sidney Allen Barker, Edward Wayne Hardwicke, JR.
