  • Publication number: 20240429711
    Abstract: The disclosure discloses a magnetic bias active suppression method and system of a hybrid distribution transformer, whether the HDT is closed or not is judged based on the grid-side current, and accordingly smooth switching of the two sets of control strategies is achieved; excitation currents of an HDT main transformer and an isolation transformer are calculated based on a magnetic potential balance principle, and nonlinear feedback is performed, and the excitation currents are superposed after an original control instruction of an HDT converter, so that magnetic bias suppression is realized on the basis of ensuring an HDT grid-side current and load voltage control function. According to the system, a complex and expensive iron core magnetic flux sensor does not need to be additionally arranged, and the DC magnetic bias of the HDT under any working condition can be eliminated while the basic control function of the HDT is not affected.

  • Publication number: 20240220219
    Abstract: A method and apparatus for computer operation improvement by flattening multi-level data structures to optimize pointer chase is provided. Within computer program code, one or more chains of multiple pointers which ultimately reference stored information to be processed are identified. These chains are analyzed to determine the feasibility of replacing the chains with a flatter data structure. In the flatter data structure, the stored information is accessible more directly. For example the data may be stored in a single array by which it can be accessed directly. When feasible, a chain is replaced with such a data structure and the computer program code is adjusted to implement the improved data structure in place of the associated chain. Candidate chains can be identified or prioritized for example on the basis of the expected impact to computer performance, e.g. in terms of operating speed or resource usage.
