This invention provides a method and system for reactive power coordination control and circulating current suppression in a wind, solar, and energy storage power plant cluster, belonging to the field of power system operation control technology. The method includes: collecting operating data from each substation and calculating a normalized circulating current index; activating a circulating current suppression mode when the index exceeds limits, obtaining the total reactive power target command for the power plant cluster, and identifying the target reactive power direction based on a dead zone threshold; dynamically clamping the upper or lower limits of reactive power output of each substation according to the target direction, generating a unidirectional blocking command to cut off the circulating current loop; and performing margin balancing control in non-suppression mode. This invention eliminates the influence of power plant capacity differences on the criteria through a normalized index, effectively solves the reactive power circulating current and control deadlock problems caused by opposite output by utilizing dynamic clamping logic based on target commands, and integrates voltage safety verification to achieve coordinated optimization of reactive power resources across multiple power plants and stable control of grid voltage.

This utility model relates to a constant-temperature germination device for soybean seeds, including a constant-temperature chamber and a frame installed inside the chamber. A water storage box is fixedly connected to the lower end of the frame, and a ventilated plate is provided on the inner side of the frame. A water-absorbing column is provided at the lower end of the ventilated plate, and a humidity-maintaining layer is provided at the upper end of the ventilated plate. A micro water pump is provided on one side of the surface of the water storage box. This utility model collects excess water through the water storage box, preventing the water from the upper layer from flowing downwards during spraying and avoiding water transfer when the seeds are stacked. Through the capillary water transport mechanism of the water-absorbing column, the water in the water storage box is evenly lifted to the humidity-maintaining layer by the capillary action of the water-absorbing column, ensuring that the gauze on the surface of the entire ventilated plate remains in a constant state of moisture, rather than relying on the upper layer spraying, thereby eliminating the humidity difference between the upper and lower layers. All seeds are in a uniformly moist environment, and the continuous water transfer from the water-absorbing column makes the humidity fluctuation smaller, ensuring the germination effect.
