Description

Technical Field

[0001] The present invention relates to the technical field of airport runway lights, and in particular to an independent power supply system for airport runway lights that integrates photovoltaics and energy storage. Background Art

[0002] Runway lights are critical airport infrastructure, providing accurate visual guidance for aircraft takeoff, landing, and taxiing at night or in low-visibility weather. Their power supply systems must be highly reliable and stable, so any power outage or failure can severely impact flight safety.

[0003] Traditional airport runway lighting power supply systems rely primarily on mains electricity, with diesel generators used as backup power sources. Transport airports are significant electricity users, with primary loads primarily classified as primary. These systems require dual power sources, including emergency power supplies. Equipment power switching times must meet the equipment's power interruption requirements. However, this traditional power supply system presents numerous challenges. Its high dependence on mains electricity means that if the mains fails and backup power sources like diesel generators also experience issues, runway lighting power will be interrupted, impacting aircraft safety. Furthermore, diesel generators are noisy and polluting, negatively impacting airport environmental protection. Long-term operation is costly, requiring regular maintenance, which increases airport operating costs.

[0004] With technological advancements, some airports are experimenting with using solar photovoltaic power generation to power runway lights. Solar energy is a clean and inexhaustible source of energy, theoretically reducing dependence on traditional utility electricity and conserving energy and emissions. However, standalone photovoltaic systems suffer from instability and are significantly affected by weather. They may not generate power on rainy days or at night, while airport runway lights require a stable 24 / 7 power supply, making photovoltaic power generation alone difficult to meet. Furthermore, energy management is relatively extensive, failing to precisely control and optimize power distribution based on real-time fluctuations in photovoltaic power generation and runway lighting load. This results in low energy efficiency and hinders the full utilization of solar power.

[0029] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the present specification. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0030] Please see the attached Figure 1 -Attached Figure 3 The embodiment of the present invention provides an independent power supply system for airport runway lights integrating photovoltaics and energy storage, comprising:

[0031] Photovoltaic power generation module, used to convert solar energy into electrical energy; photovoltaic power generation module includes multiple photovoltaic cell groups, each photovoltaic cell group is connected to the inverter through a junction box, and the inverter is connected to the intelligent energy management module, which converts the direct current generated by the photovoltaic cell group into alternating current and transmits it to the intelligent energy management module.

[0032] Specifically, multiple photovoltaic cell groups are the basic units of photovoltaic power generation modules. Each photovoltaic cell group is composed of several photovoltaic cells (single-crystal silicon cells, polycrystalline silicon cells or thin-film cells). Photovoltaic cells work based on the principle of the photoelectric effect. When sunlight shines on the surface of the photovoltaic cell, the photon energy is absorbed by the cell, causing the electrons inside the cell to transition, thereby generating direct current. These photovoltaic cell groups are installed near airport runways or other open, unobstructed locations to ensure that they can fully receive sunlight. They are arranged in a certain array to maximize the efficiency of capturing solar energy.

[0033] The combiner box combines the output current of multiple photovoltaic arrays, reducing the complexity of subsequent wiring connections. It is equipped with fuses or other overload protection devices. If a photovoltaic array or circuit fails, the fuse automatically blows, disconnecting the faulty circuit and protecting the entire photovoltaic power generation system from damage while ensuring that other functioning arrays can continue to operate.

[0034] The inverter is the interface device between the photovoltaic power generation module and the intelligent energy management module. It receives DC power from the combiner box and converts it into AC power through internal power electronic circuits.

[0035] The inverter also features maximum power point tracking (MPPT). Since the output power of photovoltaic cells is affected by environmental factors such as sunlight intensity and temperature, MPPT control can adjust the operating state of the photovoltaic cell array in real time, ensuring that it always operates near its maximum power point. This improves photovoltaic power generation efficiency and ensures that as much solar energy as possible is converted into electricity and delivered to the intelligent energy management module. The inverter is connected to the intelligent energy management module. In addition to power transmission, it also provides real-time feedback on photovoltaic power generation data to the intelligent energy management module. Based on this data, combined with the status of the energy storage module and the runway lighting load requirements, the intelligent energy management module precisely manages and controls the energy of the photovoltaic power generation module.

[0036] The energy storage module is connected to the photovoltaic power generation module and is used to store the electricity generated by the photovoltaic power generation module; the energy storage module includes multiple energy storage battery packs, each of which is connected to the intelligent energy management module through a battery management system. The battery management system is used to monitor the status parameters of the energy storage battery pack and feed the status parameters back to the intelligent energy management module to achieve charge and discharge control and protection of the energy storage battery pack.

[0037] Specifically, the energy storage module plays a key role in the system, providing energy buffering and stabilizing power supply. Connected to the photovoltaic power generation module, its primary function is to store the electricity generated by the module. When photovoltaic power generation exceeds the power demand of the runway lighting load, the excess energy is absorbed and stored by the energy storage module. When photovoltaic power generation is insufficient, the module releases the stored energy, ensuring a continuous and stable power supply for the runway lighting load.

[0038] Each energy storage battery pack is connected to the intelligent energy management module through the battery management system. The battery management system mainly undertakes the following important functions:

[0039] Condition monitoring: Real-time monitoring of various parameters of the energy storage battery pack, including but not limited to the battery's voltage, current, temperature, state of charge (SOC), and state of health (SOH). For example, sensors deployed within the battery pack accurately measure the voltage of each cell to ensure it operates within a reasonable voltage range, avoiding damage caused by overcharging or over-discharging. Battery temperature is also monitored to prevent safety issues or performance degradation caused by excessively high or low temperatures.

[0040] Data Feedback and Communication: Monitored battery pack status parameter data is promptly fed back to the intelligent energy management module. This communication connection enables the intelligent energy management module to fully understand the real-time operating status of the energy storage module, providing an accurate basis for subsequent charge and discharge control and energy management decisions.

[0041] Charge and Discharge Control: Based on instructions from the intelligent energy management module and the battery status information it monitors, the system precisely controls the charge and discharge of the energy storage battery pack. For example, when the photovoltaic power generation module generates sufficient energy and the battery SOC is low, the battery management system controls the battery pack's charging, properly adjusting the charging current and voltage to ensure the battery pack completes the charging process safely and efficiently. When the runway lighting load requires energy and the battery SOC is high, the system controls the battery pack's discharge to power the load. The system also optimizes the discharge process based on the battery's discharge characteristics to extend the battery's service life.

[0042] Protection functions: The system has multiple protection functions for the energy storage battery pack. For example, the overcharge protection automatically cuts off the charging circuit when the battery voltage reaches the set overcharge threshold, preventing dangerous situations such as bulging and fire caused by overcharging. The over-discharge protection cuts off the discharge circuit when the battery voltage drops to the over-discharge threshold, preventing irreversible capacity loss caused by excessive discharge. It also has short-circuit protection and over-temperature protection functions, comprehensively ensuring the safe and reliable operation of the energy storage battery pack.

[0043] The intelligent energy management module, connected to the photovoltaic power generation module and the energy storage module, is used to control the energy flow between the two modules and distribute and manage electrical energy according to preset strategies. The intelligent energy management module includes a data acquisition unit for collecting power generation data from the photovoltaic power generation module, energy storage data from the energy storage module, and power consumption data from the runway light load module; a processing unit, connected to the data acquisition unit, for analyzing and processing the collected data and generating control instructions based on a preset energy management algorithm; and a control unit, connected to the processing unit, for controlling the photovoltaic power generation module, energy storage module, and runway light load module according to the control instructions. The processing unit uses an energy prediction model based on a machine learning algorithm, combined with historical meteorological data and electricity consumption data, to predict future photovoltaic power generation and runway light power load, and uses an optimization algorithm to formulate the optimal energy management strategy.

[0044] Specifically, the intelligent energy management module is the core control unit of the entire independent power supply system for the airport runway lights. It is connected to the photovoltaic power generation module and the energy storage module, and is primarily responsible for regulating the energy transmission flow between the photovoltaic power generation module and the energy storage module. At the same time, based on the preset energy management strategy, the generated electricity is rationally distributed and precisely controlled to ensure efficient utilization of electricity and meet the power needs of the runway lights. The module contains a data acquisition unit, whose function is to collect power generation data from the photovoltaic power generation module, such as power generation power and sunlight intensity; it also collects energy storage data from the energy storage module, such as the current state of charge of the energy storage battery pack and the charge and discharge current; and power consumption data from the runway light load module, including the real-time power and cumulative power consumption of each runway light group. This data is transmitted to the data acquisition unit via an electrical connection, providing basic information for subsequent energy management.

[0045] After data collection is complete, the processing unit, connected to the data acquisition unit, takes over. It performs in-depth analysis and processing based on the collected data. The processing unit incorporates a built-in energy prediction model based on machine learning algorithms. This model uses historical meteorological data and electricity consumption data as inputs to predict future photovoltaic power generation and runway lighting power load. This prediction provides advance information on photovoltaic power generation surpluses and shortages, as well as power demand trends for the runway lighting.

[0046] After obtaining the prediction results, the processing unit further utilizes optimization algorithms to comprehensively consider multiple objectives, including system economics, stability, and power supply reliability, to develop an optimal energy management strategy. For example, when photovoltaic power generation is sufficient and the energy storage battery has surplus power, excess energy is prioritized for storage. If it is predicted that photovoltaic power generation will decrease and the power load for the runway lights will increase, the energy storage module discharge plan is appropriately arranged to ensure sufficient power for the runway lights.

[0047] A runway light load module is connected to the intelligent energy management module and is used to receive power provided by the intelligent energy management module for operating the runway lights;

[0048] Among them, interactive communication and energy transmission are achieved between the photovoltaic power generation module, energy storage module, intelligent energy management module and runway light load module through electrical connection.

[0049] The system also includes a photovoltaic panel dynamic tracking device, which is connected to the photovoltaic power generation module and is used to adjust the angle of the photovoltaic cell array in real time based on changes in the sun's position to improve photovoltaic power generation efficiency. The photovoltaic panel dynamic tracking device includes a bracket, a drive mechanism, and an angle sensor. The bracket is used to mount the photovoltaic cell array. The drive mechanism is connected to the bracket and is used to drive the bracket to rotate to adjust the angle of the photovoltaic cell array. The angle sensor is used to detect the real-time angle of the photovoltaic cell array and feed the angle signal back to the intelligent energy management module. The intelligent energy management module controls the operation of the drive mechanism based on the angle signal.

[0050] Specifically, the photovoltaic panel dynamic tracking device consists of three main parts: a bracket, a drive mechanism, and an angle sensor. The bracket is the basic structure of the entire device, used to firmly mount and support the photovoltaic cell array while also allowing for flexible rotation. The drive mechanism is connected to the bracket and provides power for its rotation. It can drive the bracket to rotate around a certain axis, thereby changing the tilt angle of the photovoltaic cell array. The angle sensor is used to monitor the real-time angle of the photovoltaic cell array. It can accurately measure the current tilt of the bracket and convert this angle information into an electrical signal.

[0051] The angle sensor transmits the real-time angle signal of the photovoltaic array to the intelligent energy management module, which uses this signal to determine whether the photovoltaic array is at the optimal lighting angle. Based on parameters such as the sun's real-time position, current power generation efficiency, and the preset optimal angle, the intelligent energy management module calculates the required angle adjustment and sends the corresponding control instructions to the drive mechanism. Upon receiving the instructions, the drive mechanism begins to operate, precisely rotating the bracket and adjusting the angle of the photovoltaic array to maximize its facing the sun, achieving efficient solar energy capture and power generation.

[0052] This dynamic tracking method allows the photovoltaic array to always receive sunlight at the optimal angle, maintaining high power generation efficiency throughout the day and seasons. Compared to photovoltaic arrays installed at fixed angles, systems using dynamic tracking devices for photovoltaic panels can significantly increase power generation, improving the energy output and economic benefits of the entire photovoltaic power generation module.

[0053] The runway light load module includes multiple runway light groups, each of which is connected to the intelligent energy management module through a power distribution unit. The power distribution unit is used to distribute and control power to the runway light groups.

[0054] It also includes a communication module, which is connected to the intelligent energy management module and the remote monitoring center respectively, and is used to realize data transmission and remote monitoring functions between the power supply system and the remote monitoring center. The remote monitoring center can use the communication module to perform real-time monitoring, parameter setting and remote control of the power supply system.

[0055] Specifically, the communication module is responsible for transmitting various data collected by the intelligent energy management module (such as the power generation power of the photovoltaic power generation module, the charge state of the energy storage module, the power consumption of the runway light load module, and the angle information of the photovoltaic panel dynamic tracking device, etc.) to the remote monitoring center in a timely and accurate manner. With the help of the communication module, the remote monitoring center can remotely monitor the power supply system. Specifically, the staff can remotely set the various parameters of the intelligent energy management module through the communication module, such as setting the charge and discharge thresholds of the energy storage module, adjusting the brightness level of the runway lights, and optimizing the operating strategy of the photovoltaic panel dynamic tracking device. In addition, when encountering emergencies or system anomalies, the remote monitoring center can quickly issue control instructions through the communication module to achieve emergency remote control of the power supply system to ensure the safe and stable operation of the system.

[0056] The use of communication modules makes the power supply system no longer limited to local management, but can achieve remote, efficient and intelligent monitoring and operation, which greatly improves the management convenience and operation efficiency of the system, and also makes it easier for technicians to find and solve problems that arise during system operation in a timely manner.

[0057] The intelligent energy management module is also connected to the airport's energy management system to receive instructions from the airport's energy management system and upload the power supply system's operating data to the airport's energy management system to achieve coordinated operation and optimized scheduling with the airport's overall energy system.

[0058] Specifically, the connection between the intelligent energy management module and the airport energy management system is designed to achieve coordinated control and optimized operation of the airport's overall energy. The airport energy management system uses information technology to integrate the usage of various types of energy at the airport, such as electricity, cold and heat sources, to achieve intelligent management of energy consumption. The intelligent energy management module uploads the operating data of the power supply system to the airport energy management system. This data includes key information such as photovoltaic power generation, energy storage status, and runway lighting load. After receiving this data, the airport energy management system can perform unified analysis and scheduling to ensure a precise match between energy supply and demand. At the same time, the intelligent energy management module receives instructions from the airport energy management system and adjusts its own operating strategy, such as optimizing the coordinated operation of photovoltaic power generation and energy storage, and rationally allocating electricity to runway lighting loads, to ensure a stable supply and efficient utilization of energy at the airport.

[0059] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
