Regenerative and Sustainable Energy Structures

NºPublicación: US2019312435A1 10/10/2019

Solicitante:
INFINITE KINGDOMS LLC [US]

Resumen de: US2019312435A1

Regenerative and Sustainable Energy Structures are integrated systems that harness the energy in the surrounding environment and the energy created by the structure itself to offset the energy required to operate the system. The systems can combine various sources of energy, such as solar, wind, hydroelectric, and physical power, and direct or store that energy to be used to power the system. For example, a water play attraction can utilize a solar panel shade structure, a hydroelectric generator under a fountain, wind turbines, and generators that can be cranked by participants. The energy generated by each of these components may be returned to the system to operate the water pump that fuels the fountain, for example. The aggregated energy is sufficient to offset the energy consumption of the system in whole or in part, and may even generate a surplus of energy that can be returned to the electrical grid.

CONTROLLING POWER EXCHANGE FROM SELF-COMMUTATED CONVERTERS

NºPublicación: US2019309728A1 10/10/2019

Solicitante:
MHI VESTAS OFFSHORE WIND AS [DK]

Resumen de: US2019309728A1

Embodiments herein describe operating a control system for a wind turbine in a first mode and second mode of operation. When in the first mode, the wind turbine provides power to a local AC grid. However, when in the second mode, the wind turbine provides power to a high-voltage direct current (HVDC) link. The control system includes a reactive power control leg and an active power control leg. To switch from the first mode to the second mode, the control system activates a PI controller coupled between the reactive and active power control legs which increases the output voltage of the wind turbine until the magnitude of the voltage activates a diode rectifier and permits the power outputted by the wind turbine to be transmitted along the HVDC link.
