Description

Technical Field

[0001] The present invention relates to the technical field of new energy equipment power supply systems, and specifically to a new energy equipment power supply system for tunnel construction in cold and high-altitude areas. Background Art

[0002] In cold, high-altitude areas, due to harsh climatic conditions, traditional power supply methods are often unable to provide stable and sufficient energy. The existing power supply system mainly relies on a single energy source, such as traditional diesel generators or local solar power generation, which has many problems. First, diesel generators are highly polluting to the environment, especially in high-altitude areas where air circulation is poor and pollutants are difficult to disperse quickly, which puts great pressure on the surrounding ecological environment. Second, a single energy source cannot meet the energy needs of different climatic conditions. For example, in rainy weather or low wind speeds, the efficiency of photovoltaic and wind power generation drops significantly, resulting in unstable energy supply. In these cases, the only option is to rely on traditional generators, but they often face the problem of over-reliance on traditional energy sources and waste a lot of resources.

[0003] Traditional power management systems often lack intelligent scheduling capabilities. Most systems rely solely on manually set or single battery charge thresholds to switch to backup power sources. This approach is not only inefficient but also prone to power shortages. Existing systems are often unable to assess changes in load demand and environmental conditions in real time, resulting in uneven power distribution and significant energy waste. In terms of data transmission, traditional monitoring systems typically rely on remote monitoring and the transmission of large amounts of real-time data. However, due to network latency, data redundancy, and other factors, the system response speed is slow, and timely response is impossible when faults occur. Especially in remote, cold, and high-altitude areas, signal coverage is poor and transmission stability is unstable. Remote monitoring data is often too complex and difficult to process in real time.

[0019] 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.

[0020] Please see the attached Figure 1 The embodiment of the present invention provides a power supply system for new energy equipment for tunnel construction in cold and high-altitude areas, comprising: New energy collection module, which collects and converts energy through photovoltaic power generation, wind power generation and emergency power generation devices, and outputs the collected energy as direct current; Specifically, in this embodiment, the new energy collection module is responsible for collecting and converting energy at tunnel construction sites in cold and high-altitude areas by integrating solar photovoltaic power generation, wind power generation, and emergency power generation devices. This module is the primary component of the system, and the power it outputs is supplied to the subsequent energy conversion and storage module and the intelligent power management module. The new energy collection module uses a variety of energy collection methods, which not only improves energy self-sufficiency but also can cope with fluctuations in energy demand under different environmental conditions. Through the combined use of these three power generation methods, the new energy collection module can provide a continuous and stable power supply during the day, in strong wind environments, and in emergency situations.

[0021] Solar photovoltaic panels are a crucial component of new energy harvesting modules, responsible for converting solar radiation into electricity. These panels are made of highly efficient monocrystalline silicon, capable of operating stably at low temperatures and high altitudes, maintaining high power generation efficiency in extreme environments.

[0022] Photovoltaic panels are installed on temporary structures at the tunnel construction site, with their specific location determined by the site's ambient lighting conditions. The system optimizes the panels' angle and orientation to maximize sunlight absorption. The panels' output current is direct current (DC), and an inverter within the system converts this DC power into AC for use by other devices.

[0023] During the current output of the photovoltaic panel, the power ( ) and light intensity ( ) and the efficiency of photovoltaic panels ( ). The specific relationship can be derived by the following formula: ; Where, is the power output by the photovoltaic panel, is the solar radiation intensity, is the effective area of the photovoltaic panel, is the conversion efficiency of the photovoltaic panel.

[0024] In cold and high-altitude areas, lighting conditions are greatly affected by factors such as weather changes and seasonal changes. Therefore, this system is designed with a maximum power point tracking (MPPT) algorithm to adapt to unstable lighting conditions and maintain the maximum efficiency of photovoltaic power generation.

[0025] Wind turbines capture wind energy through rotors, driving generators that convert mechanical energy into electrical energy. Wind turbines are installed in areas with abundant winds, such as tunnel openings or upwind of construction sites, utilizing local wind speeds to provide continuous power.

[0026] The working principle of a wind turbine is to generate mechanical energy through the rotation of the wind rotor and transmit it to the generator. The generator converts the mechanical energy into electrical energy, which is then converted into direct current through a rectifier and combined with the output current of the photovoltaic power generation system. The output power of the wind turbine ( ) and wind speed ( ) and the effective wind-catching area of the wind wheel ( ) and the efficiency of the wind wheel ( ). The specific relationship can be expressed by the following formula ; Where, is the output power of wind power generation, is the air density, is the wind-catching area of the wind wheel, is the wind speed, The efficiency of the wind turbine.

[0027] Wind power generation equipment can effectively utilize natural wind resources, provide power support in conditions of insufficient sunlight, and ensure stable operation of the system.

[0028] The emergency generator acts as a backup power source when sunlight and wind are insufficient, ensuring uninterrupted power supply to the system. The emergency generator utilizes a diesel generator, which offers fast startup response and strong adaptability, making it particularly suitable for the harsh environments of high-altitude, cold regions.

[0029] The emergency generator is activated through an intelligent power management and dispatch module. When the system's renewable energy resources are insufficient to meet power demand, the diesel generator automatically starts and supplies power to the system. The generator's output is converted to direct current (DC) by a rectifier and combined with current from photovoltaic and wind power generation to provide stable power support.

[0030] The new energy collection module provides power through photovoltaic power generation, wind power generation, and emergency power generation devices. All collected power is converted into direct current through rectifiers and inverters, and distributed according to system needs through the power management module.

[0031] The power output from each generating unit is combined to ensure rational power distribution and conversion. This power consolidation is optimized through a power allocation algorithm. This algorithm dynamically adjusts the contribution of each power source based on the system's real-time load demand and the output of each generating unit, thereby improving overall system efficiency.

[0032] A source conversion and storage module, connected to the new energy acquisition module, is used to convert the collected direct current into alternating current and store it through an energy storage unit. The module includes an inverter, an energy storage device, and a battery heating protection system; Specifically, the source conversion and storage module in this embodiment converts the DC power collected by the new energy collection module into AC power via an inverter and stores excess energy in an energy storage device (such as a lithium battery). The module also includes a battery heating protection system to ensure proper battery operation in low-temperature environments.

[0033] The inverter is a core component in the power conversion and storage module, responsible for converting the DC power output by the new energy collection module into AC power suitable for tunnel construction equipment. The inverter converts DC power to AC power and controls the output waveform through pulse-width modulation (PWM) technology, thereby improving system efficiency.

[0034] When the inverter is working, the input DC voltage ( ) is converted into a stable AC voltage ( ). Output power of the inverter ( ) and input power ( ) can be expressed by the following formula; ; Where, is the power output by the inverter, is the output voltage, is the output current, is the efficiency of the inverter, is the input power.

[0035] The inverter uses efficient power conversion technology to ensure that power loss is minimized during the conversion process, thereby improving the overall efficiency of the system.

[0036] Energy storage devices are used to store excess power from renewable energy harvesting modules or inverters, providing a stable power supply when power demand increases or renewable energy harvesting capacity is insufficient. Preferably, lithium batteries are used, as they offer high energy density, long life, and strong low-temperature resistance, making them suitable for use in cold and high-altitude areas.

[0037] The charging and discharging process of lithium batteries is controlled by the battery management system (BMS). The BMS monitors the battery power, temperature and other parameters in real time to ensure that the battery operates within a safe range. ) and the battery voltage ( ) and current ( ) have the following relationship: ; Where, is the charge and discharge power of the battery, is the battery voltage, is the battery current.

[0038] The battery's charging status is controlled by a battery management system (BMS), which ensures that the battery does not overcharge during charging to avoid battery damage, and extends the battery life by dynamically adjusting the charging current and voltage.

[0039] In cold, high-altitude areas, low temperatures can cause lithium battery performance degradation or damage. To ensure proper battery operation in low-temperature conditions, the power conversion and storage module of this invention incorporates a battery heating protection system. This system includes a battery heating device that heats the battery to maintain it within an appropriate operating temperature range.

[0040] The battery heating protection system calculates the heating power using the following formula : ; Where, is the heating power, For the quality of the battery, is the specific heat capacity of the battery, is the temperature difference of the battery.

[0041] When the ambient temperature is lower than the set threshold, the battery heating protection system automatically starts to ensure that the battery's operating temperature remains within an appropriate range, thereby ensuring normal use of the battery.

[0042] The intelligent power management and allocation module is connected to the energy conversion and storage module to intelligently allocate power according to the collected power and power demand, and adjust power distribution according to battery status and load conditions; Specifically, the intelligent power management and allocation module in this embodiment optimizes power distribution by monitoring battery charge, load demand, and system status in real time, prioritizing clean energy and automatically activating diesel generators for emergency power replenishment when power is insufficient. The module also uses artificial intelligence algorithms to predict load demand and automatically adjust power supply strategies to improve energy efficiency.

[0043] The intelligent battery management system (BMS) is responsible for real-time monitoring of the battery's power status and adjusting the power distribution according to the battery's charging and discharging status. )、Battery voltage( ) and current ( ) to ensure that the battery operates in the best condition and optimizes battery charging and discharging operations. The intelligent battery management system calculates the battery discharge power ( ); ; Where, is the battery output power, is the battery voltage, is the battery current.

[0044] Through this process, the system can efficiently manage the battery's power output and storage, and adjust the battery's charging and discharging strategies according to load demand.

[0045] The intelligent power management and allocation module distributes power using the following formula to ensure that the system can be reasonably scheduled according to actual needs, especially when the power supply is insufficient, the power source can be reasonably selected to supplement it.

[0046] First, the module determines the total power demand and the optimal power distribution according to the following formula: ; Where, is the total electricity demand, The power required by the load, is the system energy loss.

[0047] Through this formula, the system can calculate the total power required in real time and take into account possible energy losses in the system to ensure the stability of power supply.

[0048] The load regulation unit is responsible for adjusting power output according to the load demand of the tunnel construction site and automatically starting the diesel generator as an emergency supplement when power is insufficient. The load regulation unit distributes power according to the following formula: ; Where, To balance the power, Output electricity to the generator, Store electricity in the battery, is the total electricity demand.

[0049] Based on this formula, the load regulation unit can start the diesel generator when the battery power is low, ensuring a stable supply of load demand. When the battery energy storage is sufficient, the system prioritizes clean energy, reducing the use of diesel generators, reducing pollution and operating costs.

[0050] The intelligent power management and dispatch module further includes artificial intelligence algorithms to predict load demand and automatically optimize power distribution strategies. This algorithm uses historical load data and environmental variables to adjust power supply in real time to improve energy efficiency and ensure stable system operation.

[0051] The workflow of the AI algorithm is as follows: First, collect historical load data, ambient temperature, wind speed, light intensity and other external conditions.

[0052] Subsequently, the load demand is predicted by training the model, and the load change trend in the future is predicted.

[0053] Finally, the power distribution strategy is automatically adjusted based on the forecast results, giving priority to clean energy (photovoltaic and wind power) and automatically scheduling battery discharge and emergency generator startup during peak power demand periods.

[0054] Through this intelligent algorithm, the system can optimize power distribution in real time, improve system efficiency, and respond quickly to changes in load demand.

[0055] A terminal power supply module, electrically connected to the intelligent power management and allocation module, for providing required power to tunnel construction equipment, including lighting systems, ventilation systems, and drilling equipment; Specifically, the terminal power supply module in this embodiment effectively distributes and regulates power from the intelligent power management and allocation module, ensuring stable power supply to each terminal device. This terminal device includes various construction equipment, such as lighting, ventilation, and other power tools. Through intelligent regulation, the module dynamically adjusts power supply based on load demand and power conditions, optimizing energy use and ensuring efficient operation of construction equipment.

[0056] The power supply module for end-user devices connects to the intelligent power management and allocation module, receiving its output power for further distribution and regulation. This module dynamically adjusts power distribution based on the power requirements of each end device and the actual power supply situation, ensuring that each device operates within the appropriate power range.

[0057] The power distribution can be described by the following formula: ; Where, Power distribution for each terminal device, The total power supplied to the system, The number of terminal devices that need power supply.

[0058] This formula shows that when multiple devices are running at the same time, the power supply module of the terminal power-consuming device will evenly distribute power to ensure that each device has sufficient power supply.

[0059] To ensure the system's power supply doesn't overload, the power supply module for end-user devices also features load management and automatic regulation. When the power demand of certain end-user devices exceeds a preset threshold, the system automatically adjusts. By monitoring the real-time power demand of each device, the module automatically activates or deactivates certain devices to prevent system overload.

[0060] To cope with fluctuating power demand in cold, high-altitude environments, the power supply module for end-user devices automatically adjusts power supply based on real-time load demand. It prioritizes clean energy sources (such as solar and wind power), and only activates energy storage devices or diesel generators when clean energy sources cannot meet demand. The module also incorporates a power scheduling algorithm that adjusts power output based on current load demand and device priority.

[0061] The power dispatch strategy can be optimized through the following model: ; Where, For the final dispatch of electricity, Powered by clean energy, Power provided to the battery, The power output of the diesel generator, , β, and γ are scheduling coefficients, which are dynamically adjusted according to actual load and demand.

[0062] Through this algorithm, the system can achieve intelligent management of power distribution, ensuring efficient energy utilization while avoiding energy waste or insufficient supply.

[0063] The power supply module for end-user devices consists of multiple power conditioning units, connected to each end device via cables. Each power conditioning unit monitors the real-time power demand of the end device through sensors and communicates with the intelligent power management and dispatch module. The power dispatch system adjusts power supply in real time based on sensor feedback to ensure that each end device operates within the predetermined power range.

[0064] The environmental monitoring and control module communicates with the intelligent power management and allocation module and the energy conversion and storage module to monitor ambient environmental parameters in real time and adjust the battery heating device and inverter operating status according to environmental conditions to ensure stable operation of the system in low-temperature and high-altitude environments; Specifically, the environmental monitoring and control module in this embodiment includes temperature and humidity sensors, wind speed sensors, and other environmental monitoring equipment for real-time monitoring of climate conditions in cold, high-altitude areas. Using the environmental data collected by these sensors, the system intelligently adjusts the battery's heating power to ensure stable operation in low-temperature environments and dynamically adjusts the battery's heating strategy based on real-time climate conditions.

[0065] The environmental monitoring and control module utilizes temperature and humidity sensors, wind speed sensors, and other climate monitoring equipment to monitor construction site conditions in real time. By collecting data such as ambient temperature, humidity, and wind speed, the system assesses the current environmental conditions and adjusts the battery heating power as needed to ensure efficient operation at extremely low temperatures.

[0066] The system adjusts the ambient temperature and battery heating power using the following formula: ; Where, is the heating power, is the adjustment coefficient, is the ambient temperature, is the lowest temperature.

[0067] This formula indicates that when the ambient temperature is lower than the minimum temperature threshold, the battery heating power will increase proportionally to ensure the battery's operating temperature. Dynamically adjust according to specific system requirements to adapt to different environmental conditions.

[0068] The environmental monitoring and control module uses data from temperature, humidity, and wind speed sensors to assess the impact of climate conditions on the battery in real time and automatically adjust the battery heating power. When temperatures are too low, the module heats the battery to ensure proper operation and prevent performance degradation or failure due to low temperatures.

[0069] Specifically, when the ambient temperature is close to or lower than the operating temperature range of the battery, the system starts the heating function and determines the heating power using the following formula: ; Where, Heating power for the battery, The minimum temperature required for the battery to work properly. is the real-time ambient temperature, is the temperature response coefficient.

[0070] This formula reflects that when the ambient temperature is lower than the required operating temperature, the system will automatically adjust the heating power according to the temperature difference to ensure that the battery temperature is not lower than the minimum operating temperature and ensure stable operation of the battery.

[0071] In cold, high-altitude areas, changes in ambient temperature are often accompanied by fluctuations in wind speed and humidity. Wind speed and humidity sensors monitor wind speed and humidity in real time, and the system adjusts heating power based on this data. Increasing wind speed can accelerate heat loss, so the system automatically increases heating power when wind speeds are high to ensure the battery temperature remains within a safe range.

[0072] Therefore, the system is regulated by the following comprehensive formula: ; Where, Heating power for the battery, is the real-time ambient temperature, is the minimum temperature threshold, is the real-time wind speed, For real-time humidity, 、 、 is the environmental adjustment factor.

[0073] Wind speed and humidity data will affect the battery heating strategy. Through this comprehensive formula, the system dynamically adjusts the heating power according to changes in ambient temperature, wind speed and humidity, thereby maintaining the battery's optimal working condition in cold and high-altitude areas.

[0074] The environmental monitoring and control module, integrated with the intelligent power management and allocation module, receives and processes data from temperature, humidity, wind speed, and other sensors. This data is transmitted to the central control unit, which automatically adjusts the battery heating power and adjusts the heating strategy based on real-time feedback. This closed-loop control system ensures that the battery heating power responds promptly to changing environmental conditions and maintains the battery within the optimal operating temperature range.

[0075] The remote monitoring and communication module is connected to the intelligent power management and allocation module and the environmental monitoring and control module through wireless communication, and is used for remote control, monitoring of system operating status and fault diagnosis; Specifically, the remote monitoring and communication module in this embodiment communicates with the intelligent power management and allocation module and the environmental monitoring and control module via wireless communication, enabling remote control, monitoring of system operating status, and fault diagnosis. Specifically, the remote monitoring and communication module includes an edge processing unit, a communication module, and a remote monitoring platform. This effectively manages data flows, improves response speed, and ensures real-time monitoring and reliable control of the system.

[0076] The remote monitoring and communication module consists of a communication module and an edge processing unit. The communication module exchanges data with the intelligent power management and dispatch module and the environmental monitoring and control module via wireless communication. The edge processing unit performs preliminary screening and anomaly detection on the uploaded data locally, reducing communication load and improving response speed.

[0077] The edge processing unit filters data and determines anomalies using the following algorithms: ; Where, For the valid data after screening, For the original collected data, is the abnormality judgment threshold, For screening and judgment functions, set them according to actual needs.

[0078] The algorithm sets a reasonable threshold ,The edge processing unit can efficiently filter invalid data, reduce the communication load, and ensure that the uploaded data is more valid and relevant.

[0079] After data screening, the edge processing unit uploads the valid data to the remote monitoring platform. The communication module receives and executes remote commands. The following steps are used to receive, parse, and execute remote commands: The communication module monitors the control instructions sent by the remote monitoring platform and transmits the instruction information to the edge processing unit.

[0080] Subsequently, the edge processing unit parses the instruction content and determines the target module type and the legitimacy of the control parameters.

[0081] If the judgment result is legal, the edge processing unit sends the control parameters to the control interface of the corresponding module.

[0082] Finally, the target module performs the corresponding control action according to the received control parameters and feeds back the execution results to the remote monitoring platform for status confirmation.

[0083] The edge processing unit parses the received instructions and determines the legitimacy of the instructions using the following formula: ; Where, The result of judging the legality of the instruction. is the instruction target module type, is the instruction control parameter, is the legitimacy judgment function.

[0084] When the instruction passes the legality verification, the edge processing unit sends the control parameters to the target module, and the target module performs the corresponding control task according to the parameters.
