Technical Field

[0001] This utility model relates to the field of power generation and energy storage, and in particular to a novel electric-steam hybrid variable frequency generator set. Background Technology

[0002] In the traditional power generation equipment sector, energy storage power supplies and digital inverter generators have long existed in a state of "separate existence and independent use," neither of which has fully met users' comprehensive needs for clean, efficient, and sustainable power supply. While energy storage power supplies offer advantages such as quiet operation, zero emissions, and portability, their battery capacity and discharge power are limited, making them unable to support the high-load, long-term continuous operation requirements of large construction equipment, emergency power supply systems, and large outdoor power consumption scenarios. On the other hand, although digital inverter generators can achieve high power output through fuel-powered operation, they still suffer from problems such as high operating noise, continuous fuel consumption leading to carbon emissions, limited functionality, and a sharp decline in fuel efficiency under low-load conditions.

[0003] Furthermore, energy storage power supplies require a long charging time after their energy is depleted, making it difficult to independently cope with sudden high load demands. Digital inverter generators, on the other hand, lack energy storage and intelligent allocation capabilities, failing to achieve buffering and optimized management of electrical energy, resulting in overall low energy utilization efficiency.

[0004] Therefore, those skilled in the art are dedicated to developing a new type of electric-steam hybrid variable frequency generator set that is easy to operate and highly practical. Summary of the Invention

[0005] In view of the above-mentioned defects of the prior art, the technical problem to be solved by this utility model is to provide a new type of electric-steam hybrid variable frequency generator set.

On the one hand, the integrated design provides the industry with a new form of "multi-energy collaborative power supply," promoting the upgrade of power generation equipment from "single function" to "multi-functional integration."

[0024] like Figure 1-7 As shown, a novel electric-gasoline hybrid variable frequency generator set includes a housing 1. In this embodiment, the housing 1 serves as the mounting base and is designed with a frame structure using high-strength metal plates. An energy storage power module 11, a variable frequency power generation module 12, and a control module are installed inside the housing 1. The energy storage power module 11 and the variable frequency power generation module 12 are arranged in an upper and lower partitioned layout within the housing 1. Specifically, the energy storage power module 11 is mainly integrated in the upper layer of the housing 1 and includes multiple high-capacity lithium iron phosphate batteries connected in series to form a battery pack 111 for storing electrical energy. In this embodiment, no specific restrictions are placed on the type and quantity of batteries; they can be rationally allocated and arranged according to actual needs. The variable frequency power generation module 12 is mainly integrated in the lower layer of the housing 1 and includes an engine 121, a fuel tank 122, and a variable frequency power generation unit 123. The variable frequency power generation module 12 drives the engine 121 through fuel and utilizes digital frequency conversion technology to ensure stable output voltage, effectively meeting the continuous power needs of exploration equipment, communication equipment, etc. Meanwhile, the vertical arrangement of the energy storage power module 11 and the frequency conversion power generation module 12 shortens the energy transmission path and avoids thermal interference between different modules.

[0025] The control module is electrically connected to both the energy storage power module 11 and the frequency converter generation module 12, and is used to control the individual or coordinated operation of the energy storage power module 11 and the frequency converter generation module 12. Specifically, the control module includes a data acquisition module and a power distribution control module. The data acquisition module is used to collect real-time operating parameters of the energy storage power module 11 and the frequency converter generation module 12, such as the remaining capacity of the battery pack 111, the discharge power of the energy storage power module 11, the rotational speed of the frequency converter generation module 12, its output power, and fuel status. The power distribution control module, based on the operating parameters collected by the data acquisition module, controls the power output ratio of the energy storage power module 11 and the frequency converter generation module 12 in real time, thereby controlling the individual or coordinated operation of the energy storage power module 11 and the frequency converter generation module 12.

[0026] In this embodiment, the novel electric-gasoline hybrid inverter generator set mainly includes three operating modes: energy storage silent output mode, digital inverter output mode, and collaborative high-power output mode. The energy storage silent output mode is suitable for scenarios such as emergency power outages in homes, temporary power supply for small shops, and silent power supply in medical facilities (such as community clinics and home oxygen concentrators). In this mode, power is supplied solely by the battery pack 111 and cooled by a silent fan 112. Under actual testing, the operating noise in this mode is below 40 decibels, close to the ambient noise level in a typical indoor environment, and there are no fuel emissions. This effectively avoids noise and air pollution in homes and medical settings, while simultaneously meeting the emergency power needs of refrigerators, lighting, and small medical equipment, ensuring the needs of daily life and basic medical care.

[0027] The digital inverter output mode is primarily suitable for scenarios such as geological exploration, forestry operations, and power supply for communication base stations in remote areas. These scenarios typically involve the lack of external charging facilities and the need for extended operating time. In this mode, the engine 121 is driven solely by fuel, and digital inverter technology ensures a stable output voltage, meeting the continuous power requirements of exploration equipment, communication equipment, etc., and preventing operational interruptions due to insufficient battery life. Simultaneously, this mode can also supply power to the battery pack 111, thus achieving efficient coordination between the silent output mode and the digital inverter output mode, ensuring continuous and stable power supply.

[0028] The collaborative high-power output mode is primarily suitable for scenarios such as sudden power outages in factory production lines, temporary power supply for construction projects, and outdoor operations of large equipment (such as cranes, water pumps, and welding machines). In these scenarios, the equipment requires high power output and stable power supply to prevent damage. In such cases, the collaborative high-power output mode can be activated. This mode combines the power of the energy storage power supply and the digital inverter generator to meet the demands of industrial-grade high-power loads, effectively solving the problems of insufficient power from traditional energy storage power supplies and poor stability of ordinary generators operating alone, thus ensuring continuous production and construction. Furthermore, actual measurements show that the novel electric-steam hybrid inverter generator set described in this application can provide a maximum continuous and stable power supply of 4500W in the collaborative high-power output mode, while voltage and frequency stability are controlled within ±1%, fully adapting to the power standards for precision industrial equipment.

[0029] The housing 1 also houses a circuit conversion module, which is electrically connected to both the energy storage power module 11 and the frequency converter module 12. Specifically, the circuit conversion module includes an overvoltage module, an overcurrent module, a short-circuit module, and an overtemperature module, all of which are electrically connected to each other. By setting up the circuit conversion module, bidirectional energy exchange between the energy storage power supply (DC) and the generator (AC) is achieved, ensuring the safety and stability of the circuit after the two types of equipment are integrated, and preventing module damage due to power fluctuations.

[0030] The housing 1 is also provided with heat dissipation ducts 13 and an operation panel 14 on both sides along its length. In this embodiment, the heat dissipation ducts 13 are several openings spaced apart on the housing 1, which are used to cool the engine 121 and the frequency converter unit 123. The operation panel 14 is electrically connected to the control module, and the output mode can be switched by manually rotating the mode switching button on the operation panel 14. At the same time, the operation panel 14 integrates one or more of the following: a power output interface, a multi-functional digital display, an alarm module, an energy display module, and a human-machine interaction module. Specifically, the power output interface includes 220V AC (dual-pin), 12V DC, and USB-C fast charging interfaces to adapt to different types of high-power loads. The human-machine interaction module includes an LED display screen, which is used to display the working mode, output power, battery level, fuel level, and fault code information in real time, and supports one-button mode switching and parameter setting. At the same time, the operation panel 14 is also equipped with a light alarm function, which improves the convenience and safety of operation. Finally, casters 15 and telescopic rods 16 are integrated into the bottom and side walls of the housing 1, respectively, to facilitate its movement.

[0031] This utility model mainly involves three core technological innovations, breaking through the technical bottlenecks of traditional power generation equipment from three dimensions: form integration, control optimization, and scenario expansion. On the one hand, the integrated design provides the industry with a new form of "multi-energy collaborative power supply," promoting the upgrade of power generation equipment from "single function" to "multi-functional integration." On the other hand, the power collaborative control technology solves the problems of stability and efficiency in multi-energy power supply, providing a replicable technical solution for the integration of new energy and traditional fuel-fired equipment. In addition, the multi-mode output design, with user needs at its core, redefines the "scenario adaptability" of power generation equipment, leading the industry to transform from "product-oriented" to "user-demand-oriented."

[0032] This utility model also provides a novel power supply method for an electric-steam hybrid variable frequency generator set, comprising the following steps: S1. Monitor the real-time power demand of the load through the control module.

[0033] S2. Based on real-time power demand, switch between collaborative high-power output mode, energy storage silent output mode and digital frequency conversion output mode.

[0034] Specifically, the different working modes switch according to the following logic: When the real-time power demand is less than or equal to a preset power threshold, and the remaining power of the energy storage power module 11 is higher than a preset power threshold, the energy storage silent output mode is activated. In this embodiment, the preset power threshold is 2000W and the preset power threshold is 20%. In other embodiments, the preset values ​​of the power threshold and power threshold can be adjusted according to actual needs.

[0035] When the remaining power of the energy storage power module 11 is lower than or equal to the preset power threshold, or when the real-time power demand exceeds the independent power supply capacity of the energy storage power module 11, the digital frequency conversion output mode is activated.

[0036] When the real-time power demand is greater than or equal to the preset power threshold, and the remaining power of the energy storage power module 11 is higher than the preset power threshold, the collaborative high-power output mode is activated.

[0037] S3. In the silent output mode of energy storage, power is supplied only by the battery pack 111 of the energy storage power module 11; in the digital frequency conversion output mode, power is supplied only by the generator of the frequency conversion power generation module 12; in the collaborative high-power output mode, the energy storage power module 11 and the frequency conversion power generation module 12 supply power in tandem.

[0038] The preferred embodiments of this utility model have been described in detail above. It should be understood that those skilled in the art can make numerous modifications and variations based on the concept of this utility model without creative effort. Therefore, all technical solutions that can be obtained by those skilled in the art based on the concept of this utility model through logical analysis, reasoning, or limited experimentation on the basis of existing technology should be within the scope of protection defined by the claims.
