Description

Technical Field

[0001] This invention relates to the field of aviation electrical technology, and in particular to a power distribution method, device, computer equipment, and medium for high-power AC loads in aircraft. Background Technology

[0002] The various electrical devices on an aircraft primarily rely on an onboard three-phase AC power system to provide their required operating power. Because the phase and frequency characteristics of the AC power supply can affect the operation of the equipment, the AC power supply for each channel is independently configured to ensure that a stable power supply can be provided to each high-power AC electrical device.

[0003] As aircraft-borne equipment continues to upgrade and optimize in terms of functionality and performance, the electrical power requirements of these devices on the aircraft platform are also showing a significant upward trend. However, the power supply for the aircraft platform mainly draws mechanical energy from the engines, and the mechanical energy that engines can provide is limited. This presents a thorny problem: how to meet the ever-increasing power demands of downstream electrical equipment while ensuring that the mechanical energy obtained by the generator does not exceed the maximum torque range allowed by the engine driveshaft. Finding this balance point has become a major challenge in the design and optimization of aircraft power supply systems. Summary of the Invention

[0004] In view of this, embodiments of the present invention provide a power distribution method for high-power AC loads in aircraft, to solve the technical problem in the prior art that it is impossible to simultaneously meet the needs of downstream electrical equipment and the limited power supply of the aircraft platform. The method includes: The number of AC channels of the aircraft is obtained, and all connected loads in the AC channels and loads of the aircraft system are obtained for each aircraft. Based on the power consumption characteristic parameters of the loads, each connected load is classified and connected loads including load types are generated. The load types include intermittent high-power loads, long-term stable high-power loads, high-frequency pulse high-power loads and other loads. The power consumption characteristic parameters include load operating time and power consumption. If the load type of the access load is the long-term stable high-power load or the high-frequency pulse high-power load, the corresponding access load is evenly distributed to each AC channel; if the load type of the access load is the intermittent high-power load, the corresponding access load is distributed to the load of the carrier system. Obtain the maximum total power consumption of the AC channel and the load of the aircraft system for each aircraft, calculate the remaining power consumption under the current access state, and according to the remaining power consumption and the power consumption of the other loads, sequentially allocate the access loads of the load type other loads to the AC channel or the load of the aircraft system for each aircraft.

[0005] This invention also provides a power distribution device for high-power AC loads in aircraft, addressing the technical problem in the prior art that it cannot simultaneously meet the needs of downstream electrical equipment and the limited power supply of the aircraft platform. The device includes: The load classification module is used to obtain the number of AC channels of the aircraft, and to obtain all the access loads in the AC channels and loads of the aircraft system for each aircraft. Based on the power consumption characteristic parameters of the loads, the access loads are classified to generate access loads including load types. The load types include intermittent high-power loads, long-term stable high-power loads, high-frequency pulse high-power loads and other loads. The power consumption characteristic parameters include the load operating time and power consumption. A high-power load distribution module is used to distribute the corresponding access load evenly to each AC channel if the load type of the access load is the long-term stable high-power load or the high-frequency pulse high-power load, and to distribute the corresponding access load to the carrier system load if the load type of the access load is the intermittent high-power load. Other load allocation modules are used to obtain the maximum total power consumption of each aircraft's AC channel and carrier system load, calculate the remaining power consumption under the current access state, and allocate the access loads of the load type other loads to the AC channel or carrier system load of each aircraft in sequence according to the remaining power consumption and the power consumption of the other loads.

[0006] This invention also provides a computer device, including a memory, a processor, and a computer program stored in the memory and executable on the processor. When the processor executes the computer program, it implements the power distribution method for any of the above-mentioned high-power AC loads of an aircraft, thereby solving the technical problem in the prior art that it is impossible to simultaneously meet the needs of downstream electrical equipment and the limited power supply of the aircraft platform.

[0007] This invention also provides a computer-readable storage medium storing a computer program that executes any of the above-described power distribution methods for high-power AC loads on aircraft, in order to solve the technical problem in the prior art that it is impossible to simultaneously meet the needs of downstream electrical equipment and the limited power supply of the aircraft platform.

Detailed Implementation

[0011] The embodiments of this application will now be described in detail with reference to the accompanying drawings.

[0012] The following specific examples illustrate the implementation of this application. Those skilled in the art can easily understand other advantages and effects of this application from the content disclosed in this specification. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. This application can also be implemented or applied through other different specific embodiments, and the details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of this application. It should be noted that, in the absence of conflict, the following embodiments and features in the embodiments can be combined with each other. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0013] In this embodiment of the invention, a power distribution method for high-power AC loads in aircraft is provided, such as... Figure 1 As shown, the method includes: Step S101: Obtain the number of AC channels of the aircraft, and obtain all the access loads in the AC channels and loads of each aircraft's carrier system. Classify each access load based on the power consumption characteristic parameters of the loads, and generate access loads including load types. The load types include intermittent high-power loads, long-term stable high-power loads, high-frequency pulse high-power loads, and other loads. The power consumption characteristic parameters include the load operating time and power consumption. Step S102: If the load type of the access load is the long-term stable high-power load or the high-frequency pulse high-power load, the corresponding access load is evenly distributed to each AC channel; if the load type of the access load is the intermittent high-power load, the corresponding access load is distributed to the carrier system load. Step S103: Obtain the maximum total power consumption of the AC channel and the load of the carrier system for each aircraft, calculate the remaining power consumption under the current access state, and according to the remaining power consumption and the power consumption of the other loads, sequentially allocate the access loads of the load type other loads to the AC channel or the load of the carrier system for each aircraft.

[0014] In practice, the following steps are used to classify each connected load based on its power consumption characteristic parameters, generating connected loads that include load type: Set load operating time thresholds and power consumption thresholds; classify the access loads that meet the first condition (load operating time less than the load operating time threshold and power consumption greater than the power consumption threshold) as intermittent high-power loads; classify the access loads that meet the second condition (load operating time greater than or equal to the load operating time threshold and power consumption greater than the power consumption threshold) as long-term stable high-power loads; classify the access loads that meet the third condition (load operating time greater than or equal to the load operating time threshold and power consumption exhibiting periodic pulses) as high-frequency pulsed high-power loads; classify the access loads that do not meet the first, second, and third conditions as other loads.

[0015] In specific implementation, the following steps are used to ensure that if the load type of the access load is a long-term stable high-power load or a high-frequency pulsed high-power load, the corresponding access load is evenly distributed to each AC channel; if the load type of the access load is an intermittent high-power load, the corresponding access load is distributed to the load of the carrier system: When the long-term stable high-power load is evenly distributed to each AC channel, ensure that the sum of the load power of each AC channel does not exceed the maximum total power consumption of the current AC channel; when the intermittent high-power load is distributed to the carrier system load, prioritize the distribution to the sub-loads with large power margins in the carrier system load; if the carrier system load includes a main AC channel and an emergency AC channel, prioritize the distribution of the intermittent high-power load to the emergency AC channel when distributing the intermittent high-power load to the carrier system load; when the high-frequency pulse high-power load is evenly distributed to each AC channel, control the start-up sequence of the high-frequency pulse high-power load and stagger the start-up of the high-frequency pulse high-power load.

[0016] Specifically, "main" and "emergency" channels were introduced into the load of the carrier system, linking intermittent high-power loads (such as hydraulic pumps) to the emergency power supply. This is an important engineering decision that ensures that critical high-power intermittent loads can still be protected by the emergency channel in the event of a main channel failure, thus improving system safety and redundancy. Distributing high-frequency, pulsed high-power loads evenly across each AC channel and using staggered startup effectively smooths the total load curve, significantly reducing the impact on the power grid and improving power quality and system stability. For high-frequency pulsed loads, even with even power distribution, simultaneous startup can still generate superimposed current surges. Staggered startup effectively smooths the total load curve, significantly reducing the impact on the power grid and improving power quality and system stability.

[0017] In specific implementation, the following steps are used to allocate the access loads of the load type "other loads" sequentially to the AC channels or the loads of the aircraft system of each aircraft based on the remaining power consumption and the power consumption of the other loads: The other loads are sorted according to their power consumption; in the sorting order, each other load is assigned to the AC channel or the carrier system load with the largest remaining power consumption, and the load power of the assigned AC channel or the carrier system load does not exceed the corresponding maximum total power consumption; the remaining power consumption is updated, and the next other load is assigned.

[0018] In practice, the following steps are used to handle AC channel failures: If any of the AC channels fails, calculate the total remaining power consumption of all normal AC channels; for each of the long-term stable high-power loads and the high-frequency pulsed high-power loads on the failed channel, perform the following operations: calculate the load-sharing power of the current AC channel based on the proportion of the remaining power consumption of each normal AC channel to the total remaining power consumption; allocate the load to the corresponding normal AC channel based on the allocated load power; after each allocation, update the remaining power consumption of each normal AC channel and the total remaining power consumption, and repeat the load allocation until all the long-term stable high-power loads and the high-frequency pulsed high-power loads on the failed channel have been allocated.

[0019] Specifically, the failure response strategy upgrades the static load allocation method to a dynamic, resilient system. It clarifies how to reallocate critical loads in extreme situations such as channel failures to maintain the aircraft's basic operational capabilities.

[0020] In practice, the following steps are used to monitor the actual power consumption of each AC channel and the load of the carrier system in real time after the load is allocated, and to dynamically adjust the load allocation based on the monitoring results: The actual power consumption of each AC channel is collected in real time, and the real-time load rate of each AC channel is calculated. Based on the real-time load rate of all AC channels, the load imbalance is calculated. If the load imbalance exceeds a first preset threshold, and the real-time load rate of all AC channels does not exceed the maximum allowable power of the AC channel, one or more of the other loads on the AC channel with a high load rate are moved to the AC channel with a low load rate. If the real-time load rate of any AC channel exceeds a second preset threshold, one or more of the intermittent high-power loads on the AC channel with the load rate exceeding the second preset threshold are unloaded or moved to other AC channels.

[0021] In practice, load distribution for extremely large loads is achieved through the following steps: When allocating the other loads based on the remaining power consumption and the power consumption of the other loads, if the power consumption of any one of the other loads exceeds the remaining power consumption of any one of the AC channels or the carrier system loads, the current other load is split into multiple sub-loads and allocated to different AC channels or the carrier system loads respectively.

[0022] Specifically, when allocating the other loads based on the remaining power consumption and the power consumption of the other loads, if the power consumption of any one of the other loads exceeds the remaining power consumption of any one of the AC channels or the carrier system loads, the current other loads are split into multiple sub-loads and allocated to different AC channels or the carrier system loads respectively.

[0023] In one embodiment of the present invention, in order to ensure that the functions and performance of high-power equipment on the aircraft are not degraded while reducing the power extracted by the power supply system from a single engine, the present invention, based on the existing AC power capacity configuration of the power supply system, conducts in-depth research on the power distribution methods of high-power equipment. Under the premise of ensuring flight safety and mission reliability, and taking into account the power consumption of various onboard devices, a power distribution method for high-power AC loads under multi-channel AC non-parallel power supply conditions is proposed. The main content is to break down the high-power AC load into smaller parts and then allocate them in a coordinated manner with other aircraft loads.

[0024] (1) Break down the whole into parts.

[0025] The traditional method for distributing power to high-power AC loads involves dividing them into three load groups, each treated as a whole and powered by the aircraft's AC channels 2, 3, and 4 respectively. This invention, after in-depth research into the original power distribution method for each load group, breaks it down at the interface with the aircraft's power supply network, effectively splitting the entire load group into multiple sub-load groups from the AC power input.

[0026] like Figure 2 As shown, the key step in unifying the loads is to study the power consumption characteristics of the lower-level loads in each load group. The key power consumption parameters to focus on are load operating time and power consumption. Each load is divided into the following four categories according to its corresponding characteristics: a) Intermittent high-power load. This type of load is characterized by its high power consumption during operation (loads exceeding 10% of rated capacity during operation can be considered high-power loads), but it only operates for a period of time throughout the entire flight mission profile, and it operates intermittently and cyclically. The operating duration is less than the short-term overload capacity of the AC power supply itself, and the operating frequency is much lower than the frequency of the aircraft AC power supply (400 times and above).

[0027] b) Long-term stable high-power load. This type of load is characterized by its high power consumption during operation, continuous operation throughout the entire flight mission profile, and relatively constant power consumption during operation.

[0028] c) High-frequency pulsed high-power loads. These loads are characterized by high power consumption, continuous operation throughout the entire flight mission profile, and periodic pulsed power characteristics. Although their operating duration is much shorter than the short-term overload capacity of the AC power supply itself, their operating frequency is basically on the same order of magnitude as or even much higher than the frequency of the aircraft's AC power supply.

[0029] d) Other loads. All other loads that do not meet the above three characteristics can be included in this category, such as intermittent low-power loads and long-term stable low-power loads.

[0030] Based on the above breakdown, the various types of loads can be further refined to form sub-load groups for each type of load, which can be fine-tuned during subsequent overall allocation.

[0031] (2) Overall allocation.

[0032] like Figure 3 As shown, based on breaking down the high-power AC load group into smaller parts, all the split sub-load groups and various electrical equipment of the aircraft are allocated in a coordinated manner. At the same time, the impact on the flight safety and mission reliability of the aircraft, as well as the workload of aircraft modifications, are fully considered. Some sub-load groups under the original high-power power supply channels are adjusted to other power supply channels, so as to achieve a basic balance of power consumption of each AC power supply channel and reduce the excessive output power of individual power supply channels.

[0033] The main strategy for overall allocation is to reorganize the four load groups separated in (1). The reorganization method is as follows: a) First, configure high-power electrical loads. Only long-term stable high-power loads and high-frequency pulse high-power loads need to be redistributed. These two types of loads should be distributed as evenly as possible to each power supply channel. At the same time, at least one power supply channel should be reserved as the carrier channel. High-frequency pulse high-power loads should be distributed to at most three other channels to ensure the power safety of the carrier channel. b) Secondly, the intermittent high-power load should be placed in the carrier channel in a), and the total power consumption of the channel should be controlled within the short-term overload capacity of the AC power supply itself. c) Allocate the sub-load groups of other types of loads to each power supply channel one by one, and calculate the steady-state maximum power consumption of each channel. The power consumption of each channel shall not exceed the rated capacity of the power supply of each channel.

[0034] In this embodiment, a computer device is provided, such as... Figure 4 As shown, it includes a memory 401, a processor 402, and a computer program stored in the memory and executable on the processor. When the processor executes the computer program, it implements the power distribution method for any of the above-mentioned high-power AC loads of an aircraft.

[0035] Specifically, the computer device can be a computer terminal, a server, or a similar computing device.

[0036] In this embodiment, a computer-readable storage medium is provided, which stores a computer program that executes any of the above-described power distribution methods for high-power AC loads in aircraft.

[0037] Specifically, computer-readable storage media include both permanent and non-permanent, removable and non-removable media, which can store information using any method or technology. Information can be computer-readable instructions, data structures, modules of programs, or other data. Examples of computer-readable storage media include, but are not limited to, phase-change memory (PRAM), static random access memory (SRAM), dynamic random access memory (DRAM), other types of random access memory (RAM), read-only memory (ROM), electrically erasable programmable read-only memory (EEPROM), flash memory or other memory technologies, CD-ROM, digital versatile optical disc (DVD) or other optical storage, magnetic tape, magnetic disk storage or other magnetic storage devices, or any other non-transferable medium that can be used to store information accessible by a computing device. As defined herein, computer-readable storage media do not include transient media, such as modulated data signals and carrier waves.

[0038] Based on the same inventive concept, this invention also provides a power distribution device for high-power AC loads in aircraft, as described in the following embodiments. Since the principle of the power distribution device for high-power AC loads in aircraft is similar to that of the power distribution method for high-power AC loads in aircraft, the implementation of the power distribution device for high-power AC loads in aircraft can refer to the implementation of the power distribution method for high-power AC loads in aircraft, and repeated details will not be elaborated further. As used below, the terms "unit" or "module" can refer to a combination of software and / or hardware that performs a predetermined function. Although the device described in the following embodiments is preferably implemented in software, hardware implementation, or a combination of software and hardware, is also possible and contemplated.

[0039] Figure 5 This is a structural block diagram of a power distribution device for high-power AC loads in aircraft, according to an embodiment of the present invention. Figure 5 As shown, it includes: a load classification module 501, a power load distribution module 502, and other load distribution modules 503. The structure is described below.

[0040] The load classification module 501 is used to obtain the number of AC channels of the aircraft, and to obtain all the access loads in the AC channels and loads of the aircraft system for each aircraft. Based on the power consumption characteristic parameters of the loads, the access loads are classified to generate access loads including load types. The load types include intermittent high-power loads, long-term stable high-power loads, high-frequency pulse high-power loads and other loads. The power consumption characteristic parameters include the load operating time and power consumption. The high-power load distribution module 502 is used to distribute the corresponding access load evenly to each AC channel if the load type of the access load is the long-term stable high-power load or the high-frequency pulse high-power load, and to distribute the corresponding access load to the carrier system load if the load type of the access load is the intermittent high-power load. Other load allocation module 503 is used to obtain the maximum total power consumption of the AC channel and the load of the carrier system of each aircraft, calculate the remaining power consumption in the current access state, and allocate the access load of the load type other load to the AC channel or the load of the carrier system of each aircraft in sequence according to the remaining power consumption and the power consumption of the other loads.

[0041] In one embodiment, the load classification module includes: The threshold setting unit is used to set the load operating time threshold and the power consumption threshold; An intermittent load setting unit is used to classify the connected loads that meet the first condition as intermittent high-power loads, based on the condition that the load working time is less than the load working time threshold and the power consumption is greater than the power consumption threshold. A stable load setting unit is used to classify the access load that meets the second condition as the long-term stable high-power load, based on the condition that the load working time is greater than or equal to the load working time threshold and the power consumption is greater than the power consumption threshold. A high-frequency pulse setting unit is used to classify the connected load that meets the third condition as the high-frequency pulse high-power load, with the load working time being greater than or equal to the load working time threshold and the power during operation being a periodic pulse. Other load classification units are used to classify the access loads that do not meet the first, second, and third conditions into other loads.

[0042] In one embodiment, a high-power load distribution module includes: A stable load distribution unit is used to ensure that the sum of the load power of each AC channel does not exceed the maximum total power consumption of the current AC channel when the long-term stable high-power load is evenly distributed to each AC channel. An intermittent load distribution unit is used to allocate the intermittent high-power load to the carrier system load, prioritizing allocation to the sub-loads with large power margins in the carrier system load. If the carrier system load includes a main AC channel and an emergency AC channel, when allocating the intermittent high-power load to the carrier system load, the intermittent high-power load is preferentially allocated to the emergency AC channel. The high-frequency pulse load distribution unit is used to control the startup sequence of the high-frequency pulse high-power load when the high-frequency pulse high-power load is evenly distributed to each AC channel, and to start the high-frequency pulse high-power load in a staggered manner.

[0043] In one embodiment, other load distribution modules include: A sorting unit is used to sort the other loads according to their power consumption. Other load allocation units are used to allocate each of the other loads to the AC channel or the carrier system load with the largest remaining power consumption in a sorting order, and to ensure that the load power of the allocated AC channel or the carrier system load does not exceed the corresponding maximum total power consumption. The circulation unit is used to update the remaining power consumption and continue to allocate it to the next other load.

[0044] In one embodiment, the above-described apparatus further includes a fault handling module.

[0045] In one embodiment, the fault handling module includes: A power calculation unit is used to calculate the total remaining power consumption of all normal AC channels if any one of the AC channels fails. The cyclic fault channel unit is configured to perform the following operations for each of the long-term stable high-power loads and the high-frequency pulsed high-power loads on the fault channel: The load sharing power calculation unit is used to calculate the load sharing power of the current AC channel based on the proportion of the remaining power of each AC channel in normal state to the total remaining power. A load distribution unit is used to distribute the load to the corresponding AC channel in normal state according to the shared load power. The repetition unit is used to update the remaining power consumption of each normal AC channel and the sum of the remaining power consumption after each allocation, and to repeatedly allocate the load until all the long-term stable high-power loads and the high-frequency pulsed high-power loads on the faulty channel have been allocated.

[0046] In one embodiment, the above-mentioned device further includes a load monitoring module.

[0047] In one embodiment, the load monitoring module includes: A dynamic load allocation unit is used to monitor the actual power consumption of each AC channel and the load of the carrier system in real time after the load allocation is completed, and to dynamically adjust the load allocation based on the monitoring results, including: The load imbalance calculation unit is used to collect the actual power consumption of each AC channel in real time and calculate the real-time load rate of each AC channel. Based on the real-time load rate of all AC channels, the load imbalance is calculated. The load migration unit is used to migrate one or more of the other loads on the AC channel with a high load rate to the AC channel with a low load rate if the load imbalance exceeds a first preset threshold and the real-time load rate of all AC channels does not exceed the maximum allowable power of the AC channel. The load offloading or migration unit is used to offload or migrate one or more of the intermittent high-power loads on the AC channel whose real-time load rate exceeds the second preset threshold to other AC channels if the real-time load rate of any of the AC channels exceeds the second preset threshold.

[0048] In one embodiment, the above-described apparatus further includes an ultra-large additional load distribution module.

[0049] In one embodiment, the other load distribution modules of the large-scale system include: The extra-large other load allocation unit is used to allocate other loads according to the remaining power consumption and the power consumption of other loads. If the power consumption of any other load exceeds the remaining power consumption of any AC channel or the carrier system load, the current other load is split into multiple sub-loads and allocated to different AC channels or the carrier system loads respectively.

[0050] The embodiments of the present invention achieve the following technical effects: The power distribution method proposed in this invention effectively reduces the maximum power consumption of each power supply channel by scientifically and rationally allocating power resources, thereby significantly increasing the safety margin of the power supply system. This improvement not only greatly enhances the reliability of the system in actual operation but also significantly enhances the feasibility of subsequent load upgrades, providing a solid guarantee for the long-term stable operation and future expansion of the system. Furthermore, the method of this invention has high universality and scalability, and can be widely applied to other aircraft or systems that employ similar power distribution methods. While meeting the power needs of downstream equipment, this method can also effectively reduce the burden and impact on the engine drive shaft, demonstrating strong versatility and applicability. This power distribution method can precisely control the excessive output power of individual power supply channels, fundamentally solving the power supply system failure problem caused by excessive load power, and ensuring the safe, stable, and efficient operation of the entire power supply system.
