Publication number: 20240097451Abstract: An exemplary renewable-energy system including a back end system coupled to an isolated DC power source and a generator powered by a renewable energy source and including first circuitry configured to convert first AC power from the generator to DC power and to provide the DC power to a DC power bus, the first circuitry further configured to initiate operation using power from the isolated DC power source. The example system further includes a front end system comprising an inverter coupled to an isolated DC power source generator. The inverter includes a ground isolation monitor interrupter (IMI) circuit coupled to the DC power bus and configured to receive the DC power and convert the DC power to second AC power for provision to a power grid. The isolated power source generator ground-isolates third AC power of the power grid for conversion to DC power for the isolated DC power source.Type: ApplicationFiled: September 5, 2023Publication date: March 21, 2024Applicant: XFlow Energy CompanyInventors: Ian D. Brownstein, Benjamin W. Strom, Jason A. Mavis

Publication number: 20240068369Abstract: A fluid turbine is described herein. The fluid turbine is subject to internal stresses, which can increase the frequency of maintenance or cost of construction, including fixing or replacing one or more components or increasing the amount of material used. One or more support arms of the fluid turbine can be provided in a given manner to generate a force during rotation that opposes one or more other forces, thereby reducing or eliminating the internal stresses exerted on the fluid turbine. For example, the one or more support arms can be provided in a given orientation or with given masses to generate the opposing force. In another example, the one or more support arms can be shaped or angled to generate an aerodynamic force.Type: ApplicationFiled: November 2, 2023Publication date: February 29, 2024Applicant: XFlow Energy CompanyInventors: Ian D.

Patent number: 11753941Abstract: A separable fluid turbine rotor turbine is described herein. The fluid turbine includes blades and support arms to adjoin the blades to a hub. The blades, support arms, or blades and supports can be assembled from a plurality of segments which are adjoined via one or more connectors. The connectors can be internal or external to the blade or support arm segments. Additional connectors can be used to adjoin the blades and support arms, the blades and the hub, and the support arms and the hub.Type: GrantFiled: April 30, 2021Date of Patent: September 12, 2023Assignee: XFlow Energy CompanyInventors: Ian D.
