Description

Technical Field

[0001] The present invention relates to the technical field of intelligent power endurance, and particularly to a coal mine power supply system and an intelligent power endurance method and system for gas power generation. Background Art

[0002] At present, due to the problem of relatively weak power grid frameworks in some areas, especially in some remote coal mine areas, the power supply system faces many challenges; in these areas, the power grid usually cannot achieve true double-loop power supply, and coal mines still rely on single-line power supply methods, making the power supply of coal mines unstable and prone to voltage fluctuations, sags, and even voltage interruptions, bringing great risks to the normal production of coal mines; especially in some important coal mine operation links, such as the ventilation system and gas drainage pump equipment, which rely heavily on power supply, and the power fluctuations directly affect the safety and production efficiency of coal mines; to address this problem, some places have begun to explore the use of technologies such as gas power generation energy storage systems, hoping to provide continuous and stable power supply when the power grid has problems and ensure the safe production of coal mines.

[0003] Although some coal mines have begun to introduce energy storage systems and gas power generation technologies to enhance the stability of power supply, there are still many deficiencies in the existing technologies in actual applications; first, there is still the problem of unstable power grid power supply in the current coal mine power supply system, and single-loop power supply cannot effectively cope with sudden situations such as voltage sags or interruptions. In this case, even if a gas power generation energy storage system is adopted, it is still impossible to ensure the rapid response of the system and the continuity of power supply; second, the existing voltage monitoring systems can usually only passively collect voltage data, lacking the ability of real-time analysis and intelligent regulation of voltage states, resulting in coal mines often being unable to take corresponding measures in a timely manner when voltage problems occur, affecting the guarantee of safe production; in addition, the existing energy storage system scheduling strategies are relatively simple, often relying only on a single voltage anomaly threshold judgment, lacking comprehensive judgment and strategy adjustment for the duration of voltage fluctuations or interruptions. For example, when the duration of voltage sag is short, the energy storage system may not need to intervene, while long-term voltage problems may cause coal mine equipment to malfunction; the existing technologies do not make full use of intelligent algorithms to analyze voltage data and lack the ability to adjust the power supply strategy of the energy storage system based on the real-time voltage state, thus affecting the stability and reliability of the system. Summary of the Invention

[0004] In view of the above existing problems, the present invention is proposed.

[0005] Therefore, the problem to be solved by the present invention is how to provide a coal mine power supply system and an intelligent endurance method for gas power generation. By establishing an electric energy storage system in the gas power station as a backup power supply, when the voltage of the coal mine power supply system drops temporarily or the voltage is interrupted, the gas power generation energy storage system can automatically intervene in the coal mine power supply system to ensure the normal operation of the main loads such as the main ventilator and gas drainage pump in the mine. When the external power supply returns to normal, the gas power generation energy storage system can automatically withdraw from the coal mine power supply system and return to the energy storage state.

The appearances of "in one embodiment" in different places in this specification do not all refer to the same embodiment, nor are they separate or alternative embodiments that exclude other embodiments.

[0024] Embodiment 1

[0025] Refer toFigure 1 , which is the first embodiment of the present invention. This embodiment provides a coal mine power supply system and an intelligent endurance method for gas power generation.

[0026] The existing intelligent endurance methods mainly have the following problems: First, at present, many coal mine power supply systems still have the problem of unstable power grid power supply. Single-loop power supply cannot effectively cope with sudden situations such as voltage sags or voltage interruptions. In this case, even if a gas power generation energy storage system is adopted, it is still impossible to ensure the rapid response of the system and the continuity of power supply; Second, the existing voltage monitoring systems usually can only passively collect voltage data, lacking the ability of real-time analysis and intelligent regulation of voltage status. As a result, when voltage problems occur, coal mines often cannot take timely countermeasures, affecting the guarantee of safe production; In addition, the existing energy storage system dispatching strategies are relatively simple, often relying only on a single voltage anomaly threshold judgment, lacking comprehensive judgment and strategy adjustment for the duration of voltage fluctuations or interruptions. For example, when the duration of a voltage sag is short, the energy storage system may not need to intervene, while long-term voltage problems may cause coal mine equipment to malfunction; The existing technology does not make full use of intelligent algorithms to analyze voltage data and lacks the ability to adjust the power supply strategy of the energy storage system in real time based on voltage status, thus affecting the stability and reliability of the system.

[0027] This application provides a solution that can effectively solve the above-mentioned problems. Next, multiple embodiments will be combined to elaborate in detail how to implement the coal mine power supply system and the intelligent endurance method for gas power generation.

[0028] Figure 1 The overall flowchart of the coal mine power supply system and the intelligent endurance method for gas power generation is shown, including:

[0029] S1: Obtain the voltage data of the coal mine power supply system and perform signal anomaly judgment to obtain the voltage status signal.

[0030] Preferably, obtaining the voltage data of the coal mine power supply system means deploying voltage monitoring sensors in the coal mine power supply system to collect voltage parameters in real time to obtain voltage data.

[0031] Furthermore, the voltage status signal includes normal voltage, voltage sag, and voltage interruption.

[0032] Specifically, the signal anomaly judgment includes: judging based on the voltage data. If the voltage status signal is greater than or equal to the first threshold, it is determined that the voltage status signal is normal voltage.

[0033] If the voltage data is less than the first threshold and greater than the second threshold, it is determined that the voltage status signal is a voltage sag.

[0034] If the voltage data is less than or equal to the second threshold, it is determined that the voltage status signal is a voltage interruption, thereby effectively detecting the abnormal voltage status and achieving the purpose of obtaining accurate voltage status signals in real time.

[0035] Preferably, through the dynamic monitoring based on the voltage status signal, the present invention can quickly identify the occurrence of voltage sags or interruptions and take timely measures to provide reliable data support for subsequent automatic intervention; the early warning of voltage abnormalities can provide sufficient time for the maintenance of the power system and avoid the impact of sudden power failures on the coal mine production system, especially on key equipment such as ventilators and gas drainage pumps.

[0036] S2: Formulate an energy storage power supply strategy based on the voltage status signal.

[0037] Preferably, formulating the energy storage power supply strategy includes the following steps: making a judgment based on the voltage status signal. If the voltage status signal is normal voltage, the original energy storage power supply strategy remains unchanged and no adjustment is required.

[0038] When the voltage status signal is a voltage sag, record the corresponding moment as the voltage sag occurrence time point, count the end time point of subsequent voltage sags, judge the duration of the voltage sag. If the duration of the voltage sag is less than or equal to T 1 , it is determined that the voltage fluctuates, the original energy storage power supply strategy remains unchanged, and a first-level alarm message is sent to the operation and maintenance personnel to prompt them to pay attention to the voltage situation.

[0039] If the duration of the voltage sag is greater than T 1 , it is determined that there is a voltage sag problem, the automatic intervention mechanism is executed, the state of the gas power generation energy storage system is adjusted to the power supply state, and a second-level alarm message is sent to the operation and maintenance personnel to prompt them to check the equipment.

[0040] When the voltage status signal is a voltage interruption, record the corresponding moment as the voltage interruption occurrence time point, count the end time point of subsequent voltage interruptions, judge the duration of the voltage interruption. If the duration of the voltage interruption is less than or equal to T 2 , it is determined that it is a voltage abnormality phenomenon, the original energy storage power supply strategy remains unchanged, and a first-level alarm message is sent to the operation and maintenance personnel to prompt them to pay attention to the voltage situation.

[0041] If the duration of the voltage interruption is greater than T 2 , it is determined that there is a voltage interruption problem, the automatic intervention mechanism is executed, the state of the gas power generation energy storage system is adjusted to the power supply state, and a third-level alarm message is sent to the operation and maintenance personnel to prompt them to perform repairs.

[0042] Preferably, by adopting differentiated strategies according to different characteristics of voltage changes, it is ensured that a rapid response can be made according to voltage changes when abnormalities occur in the power system, reducing potential threats to coal mine production and safety. It can automatically judge the voltage state and trigger corresponding actions, such as adjusting the state of the energy storage system or sending an alarm, greatly reducing the need for manual intervention and improving the intelligent level of the coal mine power supply system.

[0043] S3: Supply power to the coal mine load based on the energy storage power supply strategy to achieve intelligent endurance of the coal mine power supply system and gas power generation.

[0044] Preferably, supplying power to the coal mine load based on the energy storage power supply strategy means establishing an electric energy storage system in the gas power station as a backup power source to obtain a gas power generation energy storage system, judging according to the state of the gas power generation energy storage system, and adjusting the power supply based on the judgment result.

[0045] Furthermore, the state of the gas power generation energy storage system includes the energy storage state and the power supply state.

[0046] Furthermore, the coal mine load includes main load equipment and non-main load equipment.

[0047] Specifically, the main load equipment includes ventilators and gas drainage pumps.

[0048] Specifically, supplying power to the coal mine load based on the energy storage power supply strategy includes: when the state of the gas power generation energy storage system is the power supply state, it is determined that there is a voltage sag or voltage interruption in the coal mine power supply system. The gas power generation energy storage system automatically intervenes in the coal mine power supply system and judges the stored energy of the gas power generation energy storage system. If the stored energy of the gas power generation energy storage system is greater than or equal to the power demands of all main load equipment, power is supplied to all main load equipment, that is, ventilators and gas drainage pumps, so that all main load equipment can operate normally.

[0049] When all main load equipment can operate normally, scheduling is carried out according to the priority of non-main load equipment and the stored energy of the gas power generation energy storage system to supply power to non-main load equipment, reducing energy consumption and ensuring the stability of power supply.

[0050] If the stored energy of the gas power generation energy storage system is less than the power demands of all main load equipment, scheduling is carried out according to the priority of main load equipment to supply power to main load equipment, so that the most important main load equipment can operate normally.

[0051] Continuously detect the real-time voltage data of the coal mine power supply system and execute the signal abnormality judgment step. If the voltage state signal is still a voltage sag or voltage interruption, it is determined that there is a fault in the coal mine power supply system, and the state of the gas power generation energy storage system remains unchanged as the power supply state.

[0052] If the voltage status signal indicates normal voltage, it is determined that the external power supply has been restored to normal, and the gas power generation energy storage system automatically exits the coal mine power supply system and returns to the energy storage state.

[0053] Preferably, by using the gas power generation energy storage system to supply power to the main load equipment in the coal mine, it is ensured that these key equipment can continue to operate normally under abnormal voltage conditions. When the gas power generation energy storage system is in the power supply state, the system will automatically intervene and continuously monitor the voltage data to ensure the stability of the power supply. If the voltage returns to normal, the energy storage system will automatically exit the power supply state and return to the energy storage state, ensuring that the power supply of the key load equipment in the coal mine will not be affected by voltage problems and guaranteeing the safe production of the coal mine; when the voltage status returns to normal, the energy storage system automatically exits the power supply state, which not only saves energy but also avoids unnecessary intervention in the system and improves the efficiency of the entire power supply system.

[0054] In summary, the present invention realizes the real-time monitoring of the state of the coal mine power system by deploying voltage monitoring sensors in the coal mine power supply system and collecting voltage data in real time. Especially in the complex environment and uneven power consumption load of the coal mine, voltage monitoring can quickly detect abnormal voltage conditions and provide accurate data support for subsequent power supply strategy adjustment; flexibly adjust the energy storage power supply strategy according to the real-time state of the power system, so as to ensure the continuous power supply of the coal mine under various power anomalies, avoid the shutdown of coal mine equipment or production interruption, ensure the normal operation of the coal mine, and at the same time avoid excessive or insufficient energy consumption, improve the energy utilization efficiency, and reduce production losses caused by power problems; the automatic intervention mechanism ensures that in the event of power anomalies, it can not only supply power to key equipment but also perform intelligent switching according to real-time data feedback to achieve the purpose of intelligent endurance.

[0055] Embodiment 2, which is an embodiment of the present invention, provides a coal mine power supply system and a gas power generation intelligent endurance system, including: an abnormality judgment module for obtaining voltage data of the coal mine power supply system and performing signal abnormality judgment to obtain a voltage status signal; a strategy formulation module for formulating an energy storage power supply strategy according to the voltage status signal; and an intelligent endurance module for adjusting the states of the gas power generation energy storage system and the coal mine power supply system based on the energy storage power supply strategy, and then supplying power to the coal mine load to achieve the intelligent endurance of the coal mine power supply system and gas power generation.

[0056] Embodiment 3, which is an embodiment of the present invention, is different from the previous embodiment in that:

[0057] As Figure 2As shown, when the above-mentioned function is implemented in the form of a software functional unit and sold or used as an independent product, it can be stored in a computer-readable storage medium. Based on such understanding, the technical solution of the present invention, in essence, or the part that contributes to the prior art, or a part of this technical solution, can be embodied in the form of a software product. This computer software product is stored in a storage medium and includes several instructions for causing a computer device (which may be a personal computer, a server, or a network device, etc.) to execute all or part of the steps of the methods described in various embodiments of the present invention. The aforementioned storage medium includes: various media that can store program codes, such as USB flash drives, mobile hard disks, read-only memories (ROM, Read-Only Memory), random access memories (RAM, Random Access Memory), magnetic disks, or optical discs.

[0058] The logic and / or steps represented in the flowchart or otherwise described herein, for example, can be considered as a predefined sequence list of executable instructions for implementing logical functions, and can be specifically implemented in any computer-readable medium for use by an instruction execution system, apparatus, or device (such as a computer-based system, a system including a processor, or other systems that can fetch and execute instructions from the instruction execution system, apparatus, or device), or in conjunction with these instruction execution systems, apparatuses, or devices. For the purposes of this specification, a "computer-readable medium" can be any device that can contain, store, communicate, propagate, or transport a program for use by or in conjunction with an instruction execution system, apparatus, or device.

[0059] More specific examples (non-exhaustive list) of computer-readable media include the following: an electrical connection part with one or more wirings (electronic device), a portable computer disk cartridge (magnetic device), random access memory (RAM), read-only memory (ROM), erasable programmable read-only memory (EPROM or flash memory), optical fiber device, and portable compact disc read-only memory (CDROM). Additionally, the computer-readable medium can even be paper or other suitable media on which the program can be printed, because the program can be obtained electronically, for example, by optically scanning the paper or other media, then editing, interpreting, or otherwise processing it as appropriate, and then storing it in a computer memory.

[0060] It should be understood that each part of the present invention can be implemented by hardware, software, firmware, or a combination thereof. In the above embodiments, multiple steps or methods can be implemented by software or firmware stored in a memory and executed by a suitable instruction execution system. For example, if implemented by hardware, as in another embodiment, any one or a combination of the following techniques well known in the art can be used: discrete logic circuits having logic gate circuits for implementing logical functions on data signals, application specific integrated circuits having appropriate combinational logic gate circuits, programmable gate arrays (PGAs), field programmable gate arrays (FPGAs), etc.

[0061] Embodiment 4, an embodiment of the present invention, provides a coal mine power supply system and a method for intelligent continuous power generation of gas. In order to verify the beneficial effects of the present invention, scientific demonstration is carried out through simulation experiments.

[0062] In this example, a coal mine power supply system is selected for testing. Voltage monitoring sensors have been installed in the system, and a gas power generation energy storage system is configured as a backup power supply to collect voltage data in real time and perform abnormal judgment on status signals. The test simulates three main voltage states: normal voltage, voltage sag, and voltage interruption. All data is collected by sensors and analyzed in real time by the control system.

[0063] By collecting the voltage data of the coal mine power supply system in real time, with a data collection period of once every 5 seconds, the collected voltage data is processed by the signal abnormal judgment module, and the voltage state is judged according to the set thresholds. The first threshold is 380V, and the second threshold is 340V. Then, different energy storage power supply strategies are formulated according to the voltage state signal. Finally, according to the execution situation of the energy storage power supply strategy, the system will supply power to the coal mine load equipment. When the state of the gas power generation energy storage system is in the power supply state, the normal operation of the ventilator and the gas drainage pump is preferentially ensured; when the voltage state returns to normal, the gas power generation energy storage system automatically returns to the energy storage state. The specific implementation data is shown in Table 1.

[0064] Table 1 Operating data table of the coal mine power supply system and the gas power generation energy storage system

[0065]

[0066] As can be seen from the above table, when the duration of the voltage sag does not exceed the set threshold, the system identifies it as voltage fluctuation and does not make adjustments to the power supply strategy, thus effectively avoiding overreaction to short-term voltage fluctuations and reducing unnecessary energy consumption. When the voltage sag lasts for more than 30 seconds, the system automatically intervenes and adjusts the gas power generation energy storage system to the power supply state, successfully ensuring the continuous power supply of the main load equipment in the coal mine. When the voltage interruption lasts for 30 seconds and does not reach the set threshold, the system does not take intervention measures but only sends an alarm. Therefore, it can be seen that the energy storage power supply strategy of the present invention has a higher level of automation and response speed compared with the prior art. Many systems in the prior art cannot automatically adjust the power supply strategy when voltage fluctuations or interruptions occur and require manual intervention. However, through real-time monitoring and intelligent analysis, the present invention can quickly make judgments to ensure the stability of the coal mine power supply system and the safe operation of equipment.

[0067] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present invention, and they should all be covered by the scope of the claims of the present invention.
