  • Patent number: 12348036
    Abstract: This application presents an adaptive arc suppression method for ground faults in distribution networks, merging active and passive relay protection strategies. The method proceeds as follows: based on collected ground parameters, the fault phase is identified; compensation current is calculated from the fault's electromotive force, ground leakage resistance, and ground capacitance; current is injected at the neutral point according to the compensation current; finally, the arc suppression scheme is executed based on the zero-sequence voltage of the network's busbars. This approach incorporates both voltage- and current-based methods, addressing the limitation of fixed operation scenarios in traditional arc suppression methods. By quickly adapting to various fault situations, this method ensures an efficient and prompt response tailored to specific scenario requirements.

  • Publication number: 20250167541
    Abstract: The provided are a method, system, and medium for active arc-extinguishing voltage-current conversion in distribution networks. The method includes: detecting a single-phase-to-ground fault in the distribution network and identifying the target faulty phase; injecting compensating currents into the target faulty phase to reduce its voltage; measuring the residual current at the fault point during the injection of compensating currents and the zero-sequence voltage of the target faulty phase; determining a critical zero-sequence voltage threshold based on the residual current at the fault point and assessing whether this critical value exceeds the present zero-sequence voltage; if so, ceasing the injection of compensating currents into the target faulty phase and instead injecting active arc-extinguishing currents at the neutral point of the distribution network to mitigate ground currents at the grounding points of the distribution network.

  • Publication number: 20250158401
    Abstract: This invention relates to a method and system for adaptive reclosing of single-phase AC transmission lines in wind power systems. The invention utilizes single-ended electrical quantity to determine the type of fault. After a fault occurs, a signal acquisition device is used to sample the voltage of the fault phase. The obtained voltage is subjected to short-time Fourier transform to extract the amplitude of the fundamental frequency voltage component, and then processed with differential amplification to construct a fault nature identification criterion. Combined with a sliding time window for fault identification, if it is identified as a permanent fault, the reclosing device is locked out; if it is identified as a transient fault, the fault disappearance time is calculated to determine the reclosing time and output the closing signal. This invention is designed for adaptive reclosing after a circuit breaker trips in wind power AC transmission lines.

  • Publication number: 20240426431
    Abstract: Systems and methods for thermal transport in space for cryogenic propellant storage tank chilldown are described. In order to maximize the storage tank chilldown thermal efficiency for the least amount of required cryogen consumption, the embodiments relate to quenching heat transfer concepts that can include the combination of cryogenic spray quenching cooling, thermal insulator thin-film coating on the tank inner surface, and spray flow pulsing. The boiling heat transfer physics that supports the concepts are described. The completed flight experiments successfully demonstrated the feasibility of the concepts and discovered that spray cooling can be an efficient cooling method for the tank chilldown in microgravity. In microgravity, the data shows that the chilldown thermal efficiency can reach 30% with a thermal insulator coating alone. Further thermal efficiencies can be made up to 50% with flow pulsing.

  • Publication number: 20240374828
    Abstract: A syringe positioning assembly includes a housing, a rotating member, a fixing member and a transmission member. The rotating member is connected to the fixing member via the transmission member, and during rotation, the rotating member can, via the transmission member, drive the fixing member to move. When the rotating member rotates in a direction away from a carrying face of the housing, the fixing member can be moved in a direction away from the fixing face. A space between the rotating member and the carrying face of the housing facilitates placement of a barrel of a syringe and a space between the fixing member and the fixing face of the housing can also facilitate placement of a barrel flange. A user can thus move the fixing member just by operating the rotating member, so that the syringe can be easily mounted and properly positioned.
