This invention relates to a grid impact compensation system and control method coupled with an air separation system, belonging to the field of air separation system technology. The system includes: an air separation system for separating air and outputting a first heat exchange medium, electrically connected to the power grid; a superconducting magnetic energy storage system including a second heat exchange medium, electrically connected to the power grid, used to compensate for instantaneous power surges to the power grid from the air separation system; and a temperature-varying coupling system connected to both the superconducting magnetic energy storage system and the air separation system. The first and second heat exchange media exchange heat within the temperature-varying coupling system. The superconducting magnetic energy storage system compensates for instantaneous power surges to the power grid. The connection between the superconducting magnetic energy storage system and the air separation system via the temperature-varying coupling system not only compensates for grid surges but also maintains the operating temperature of the superconducting magnetic energy storage system, significantly reducing energy consumption when the superconducting magnetic energy storage system and the air separation system are used in conjunction.

This utility model discloses a damping-actively adjustable vibration damper, belonging to the technical field of vibration damper technology. The damping-actively adjustable vibration damper includes an oil tank, inside which is a working cylinder. An oil storage chamber is separated from the oil tank by the working cylinder. A piston rod is installed inside the working cylinder, and a reset valve assembly is bolted to the bottom end of the piston rod. A bottom cover is welded to the bottom of the oil tank, and a compression valve assembly is installed on the upper part of the bottom cover. The compression valve assembly and the working cylinder form a working chamber, which is filled with magnetorheological fluid. When the excitation coil malfunctions, only the coil protective cover needs to be opened to remove the excitation coil for repair or replacement, without disassembling the internal structure of the vibration damper. This greatly reduces the difficulty of maintenance and upkeep of the magnetorheological vibration damper, making it convenient to use.
