  • Publication number: 20240386271
    Abstract: A system, apparatus, computer program product, and method use a convolutional neural network to auto-determine a first floor height (FFH) and a FFH elevation (FFE) of a building. The FFH, and FFE of the building are determined with respect to the terrain or surface of the parcel of land on which the building is located. In turn, by knowing the FFH and/or FFE of the building on the parcel, it is possible to use that information while performing a flood risk assessment to a property without requiring a personal inspection of the parcel by a human.

  • Publication number: 20240275269
    Abstract: This document describes systems and techniques for a control system for a grid-forming inverter. In aspects, a reactive power current-limiting subsystem, based on a measured reactive power, is configured to generate a first signal representing a magnitude of a modulation waveform presentable to a pulse-width modulator configured to direct transistors in the inverter of the grid-forming inverter. An active power current-limiting subsystem, based at least in part on a measured active power, is configured to generate a second signal representing a rotating phase angle of the modulation waveform presentable to the pulse-width modulator. The reactive power current-limiting subsystem and active power current-limiting subsystem are configured to cause an alternating current (AC) output of the grid-forming inverter to resume a nominal form subsequent to current being directed around one or more transistors in an inverter to prevent an excessive output current from flowing through the one or more transistors.

  • Publication number: 20240079947
    Abstract: This document describes systems and techniques for a current-limiting control strategy for single-loop droop-controlled grid-forming inverters. In aspects, a hysteresis module is configured to compare an output current detected across one or more transistors in an inverter controlled by the single-loop droop converter with a specified maximum current and to generate an overcurrent signal. The overcurrent signal presents a fault signal responsive to the output current exceeding the specified maximum current. A logic array is configured to logically combine gate control signals generated by the single-loop droop controller to selectively direct the one or more transistors to allow the output current to flow therethrough with the overcurrent signal to present modified gate control signals to the one or more transistors.

  • Patent number: 11813695
    Abstract: A method for forming a large-diameter special-shaped cross section thin-wall tubular part. A tailor welded barrel blank is adopted as an original blank for forming of the large-diameter special-shaped cross section thin-wall tubular part. After a desired shape is formed, the original weld joint is removed and butt joint tailor welding is performed on the tubular part again. Since the tailor weld joint of the original barrel blank is removed from the final part, there is no need to consider the consistency or coordination of the microstructure of the weld joint and the base metal during the forming process and the subsequent thermal treatment process.
