Description

Technical Field

[0001] The present invention relates to the technical field of power emergency protection, and in particular to an emergency energy rapid response system and device. Background Art

[0002] In existing technology, when a grid fault occurs, traditional UPSs rely on a single battery, making them unable to start up quickly and provide stable power output, and unable to cope with short-term high-power surges. Furthermore, simply connecting capacitors and batteries in parallel results in circulating current losses exceeding 15% and capacity utilization below 70%. Furthermore, mechanical contactors have arcing times exceeding 8ms, and SiC alone results in high conduction losses (>3kW / 100A). Furthermore, fixed-threshold solutions are prone to false operation under light loads (e.g., triggered by an 80% voltage sag) and are sluggish under heavy loads. Traditional static transfer switches (STSs) switch all loads uniformly, causing secondary equipment to preempt critical load resources.

[0003] Therefore, it is necessary to provide an emergency energy rapid response system and device to solve the above technical problems. Summary of the Invention

However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0020] Next, the present invention is described in detail with reference to schematic diagrams.

Furthermore, these schematic diagrams are merely illustrative and should not limit the scope of protection of the present invention.

[0021] Furthermore, the term "one embodiment" or "embodiment" herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in various places throughout this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0022] Example 1

[0023] Reference Figures 1-2The first embodiment of the present invention is an emergency energy rapid response system, characterized in that it includes a power grid state perception unit, a composite energy storage unit, a load classification manager, a dynamic power coordinator, an intelligent switching actuator, a rapid deployment carrier and an intelligent load manager. The power grid state perception unit monitors the power grid voltage, frequency and distortion rate in real time; the composite energy storage unit is composed of a power type energy storage element and an energy type energy storage element; the load classification manager configures different response strategies according to the importance of the equipment; the dynamic power coordinator adjusts the output ratio of each element in the composite energy storage unit in real time; the rapid deployment carrier supports two forms: mobile rapid response vehicles and fixed energy stations; the intelligent switching actuator adopts a dual-channel structure in which solid-state switches and mechanical switches work together; the intelligent load manager executes a hierarchical power supply strategy according to a preset priority;

[0024] Specifically, the composite energy storage unit and the dynamic power coordination mechanism, the power type energy storage element (supercapacitor) and the energy type energy storage element (lithium battery) are coupled through a multi-phase staggered parallel DC / DC topology, combined with the real-time output ratio adjustment of the dynamic power coordinator: when an instantaneous high power demand (≥100kW / 100ms) is detected, the supercapacitor output ratio is automatically increased to 70%-90%; during steady-state operation, the lithium battery takes on more than 80% of the energy supply, eliminating the >15% circulation loss caused by the simple parallel connection of traditional capacitors and batteries, and the capacity utilization rate is increased from <70% to >92%. The working process of the intelligent switching actuator includes: the solid-state switch immediately establishes a temporary path when a grid fault is detected; the mechanical switch switches to the main path at the moment when the current passes through zero; the zero-crossing detection device ensures that the switching sequence of the two branches is accurately coordinated. The dynamic power coordinator includes a voltage drop prediction model trained based on historical grid data and a switching threshold that is adjusted in real time with the load power. The solid-state switch (SiC MOSFET) establishes a temporary path within 5μs of a grid fault, bearing the initial surge current of ≤5ms. The mechanical switch (vacuum interrupter) switches to the main path at the current zero-crossing point under the control of a zero-crossing detection device. This application establishes a multi-level safety protection mechanism, including arc suppression devices configured on the mechanical switches; multiple electrical isolations are set for critical circuits; and abnormal conditions trigger an automatic protection program. By establishing an arc suppression device in conjunction with a multi-level safety protection mechanism, the arcing time is reduced to ≤2ms (a 75% reduction compared to arcing times >8ms in the prior art). The SiC is only briefly turned on, resulting in system losses of <1kW / 100A (compared to >3kW / 100A in the prior art). The load classification manager divides connected devices into the following three categories: zero-delay protection (life support and safety control equipment); short-interruption tolerance (industrial production control equipment); and flexible start-up (auxiliary power equipment). The dynamic power coordinator executes the following control logic: the power-type energy storage element responds to instantaneous high-power demands first; the energy-type energy storage element undertakes the task of continuous and stable power supply; when the load suddenly changes, the two automatically match the output ratio.

[0025] Dynamic Power Coordinator Integration: LSTM-based voltage drop prediction model (training data volume > 100,000 sets);

[0026] Load power adaptive switching threshold:

[0027] Load factor Toggle threshold adjustment Defects of existing technology ＜30％ 70％→60％ Light load misoperation ＞80％ 80％→85％ Slow response under heavy load

[0028] The intelligent load manager executes the tiered strategy synchronously:

[0029] Zero-delay protection (life-support equipment): 0ms switching + supercapacitor direct supply;

[0030] Short-term interruption tolerance (industrial equipment): ≤10ms switching + lithium battery support;

[0031] Flexible start-up (auxiliary equipment): 500ms slow start;

[0032] The fixed energy station includes: a pre-installed energy access track; an extreme weather protection system; and a grid seamless switching controller. Specifically, the rapid deployment carrier is optimized into: a fixed energy station and a mobile rapid response vehicle. For the fixed energy station, the pre-installed energy access track has a docking time of ≤5 minutes; the seamless switching controller switches between the mains and energy storage in <1ms; the extreme weather protection system has a wide operating temperature range of -40°C to 85°C; and the mobile rapid response vehicle has a containerized energy storage unit with a power density of ≥5kW / kg, and can be connected to the grid in 30 minutes. Furthermore, the intelligent self-checking and maintenance unit includes energy storage element health status diagnosis; switch mechanism operation reliability testing; and system fault simulation drills. Simultaneously, the present invention establishes a multi-level safety protection mechanism, including mechanical switches equipped with arc suppression devices; multiple electrical isolations for critical circuits; and abnormal conditions triggering automatic protection programs. Specifically, the multi-level safety protection mechanism includes: the magnetic field strength of the permanent magnet arc blowing device equipped with the mechanical switch is ≥0.3T; the insulation strength of the triple electrical isolation for critical circuits is ≥10kV; and the IGBT-level active protection response is <10ms. Intelligent self-diagnosis and maintenance unit: Monthly energy storage health diagnosis, alarm when supercapacitor ESR changes >15%; 100,000 reliability tests on switch mechanisms; and quarterly fault simulation drills that cover 90% of fault scenarios.

[0033] In summary, the present invention achieves a power supply switching delay of ≤1ms through dynamic coordination of composite energy storage, switching timing optimization, and threshold-load linkage control, while ensuring zero-interruption operation of life-support equipment. It also has a short-term impact support capacity of 500kW / 0.5s, and fixed emergency energy stations can serve as backup energy for important places, ensuring the normal operation of critical facilities.
