Hydrogen energy system modeling method, electronic device and storage medium

PendingCN122287134AAccurately reflect true impactImprove physical accuracyIntegrated energy systemProcess engineering
This invention discloses a modeling method, electronic device, and storage medium for hydrogen energy systems. The method includes: establishing a hydrogen production mass flow model for an electrolyzer, and using a multi-condition linearization method to handle the nonlinear operating efficiency of the electrolyzer; establishing a storage mass flow model for a hydrogen storage tank, dynamically characterizing its effective capacity based on the tank's physical volume, operating pressure, and ambient temperature parameters; constructing a hydrogen mass flow bus, linking the electrolyzer's hydrogen production variable and the storage tank's hydrogen filling variable to this bus, and establishing hydrogen mass flow balance constraints among the models to characterize that at any given time, the total amount of hydrogen flowing into the bus equals the total amount flowing out. This invention solves the problem of insufficient accuracy in traditional models, achieving a balance between high accuracy of the equipment model and high solution efficiency for the optimization problem, providing a reliable modeling foundation for the optimal scheduling of hydrogen-containing integrated energy systems.

A torque plate and an impact test bench having the same

ActiveCN224286581UGuaranteed linearityImprove compatibilityMaterial strength using steady torsional forcesMaterial strength using single impulsive forceClassical mechanicsTorque transmission
This utility model relates to a bidirectional torque plate for an impact testing bench, comprising a torque plate body detachably mounted on a torque limiter under test. The torque plate body has lever arms extending radially to both sides, with each lever arm's end forming a torque-acting end mechanically connected to a force sensor. When the torque limiter under test is subjected to an impact load, the torque plate body tends to rotate clockwise or counterclockwise. When one lever arm applies pressure to the corresponding force sensor through its torque-acting end, the other lever arm applies tension to the corresponding force sensor through its torque-acting end, thus achieving bidirectional measurement of tensile and compressive forces. This utility model improves detection accuracy by canceling out the self-weight of symmetrical torque couples, effectively achieving precise control of the torque transmission path under impact load, thereby enhancing the stability and reliability of torque measurement data.
