Description

Technical Field

[0001] This application relates to the field of compressed air energy storage technology, and in particular to a method and system for controlling the inlet temperature of an air storage facility that takes into account the lifespan of the storage facility. Background Technology

[0002] Among related technologies, compressed air energy storage, as a large-scale, long-cycle energy storage technology, has become one of the key technologies to support the consumption of renewable energy and ensure the stable operation of the power grid.

[0003] However, in actual operation, after one storage-release cycle, the temperature of the gas storage tank will decrease due to factors such as air expansion releasing energy and heat loss. The smaller the volume of the gas storage tank, the more severe the temperature drop. After long-term operation, this cumulative temperature decay will continuously damage the sealing layer, shorten the life of the gas storage tank, and increase the system maintenance cost. As the core storage unit of the compressed air energy storage system, the operating temperature of the gas storage tank directly affects the performance of the sealing layer materials (such as rubber seals and concrete impermeable layers) and structural stability. When the temperature of the gas storage tank is lower than the design temperature for a long time or fluctuates frequently and significantly, the sealing layer is prone to problems such as shrinkage cracking and ice expansion damage, leading to high-pressure air leakage and significantly shortening the service life of the gas storage tank.

[0004] Therefore, solving the problems of sealing layer failure and structural stability caused by the cumulative temperature decay of gas storage has become a key technical bottleneck that urgently needs to be overcome in the current development of compressed air energy storage technology. Summary of the Invention This application provides a gas storage inlet temperature control method and system that takes into account the lifespan of the gas storage facility, in order to solve the problems in related technologies, such as the temperature decay of the gas storage facility caused by factors such as air expansion and energy release and heat loss, which in turn affects the performance of the sealing layer material and the structural stability, resulting in a shortened lifespan of the gas storage facility.

[0005] The first aspect of this application provides a method for controlling the inlet temperature of a gas storage facility considering its lifespan, comprising the following steps: determining a temperature compensation amount for the inlet temperature of a target gas storage facility based on a pre-built temperature-volume correlation model, and determining a reference value for the inlet temperature of the target gas storage facility based on the temperature compensation amount, wherein the temperature-volume correlation model of the gas storage facility is constructed from historical operating data of gas storage facilities of different volumes; generating a flow rate setpoint for the compression-side heat exchange medium based on the reference value for the inlet temperature and the operating parameters of the temperature control loop; comparing the setpoint with the actual flow rate of the compression-side heat exchange medium to obtain a flow rate deviation, calculating the change in the opening of the flow regulating valve of the compression-side heat exchange system based on the flow rate deviation, adjusting the valve opening of the flow regulating valve based on the change in opening, and adjusting the outlet temperature of the compressor based on the real-time pressure at the inlet of the target gas storage facility, thereby controlling the inlet temperature of the target gas storage facility through pressure-temperature coupling regulation.

[0006] By employing the aforementioned technical means, the reference value for the gas storage inlet temperature can be determined by combining the "temperature-volume correlation model" with the lifespan requirements of the gas storage facility. Based on this reference value, and combined with the key operating parameters of the control system acquired in real time, the setpoint for the flow rate of the heat exchange medium on the compression side can be derived. Furthermore, based on this setpoint, the opening of the flow regulating valve can be automatically adjusted by the secondary loop controller, and the compressor outlet temperature can be corrected by implementing pressure. This ensures that the compressor outlet temperature meets the gas storage inlet temperature requirements, thereby ensuring that the temperature control conforms to the lifespan requirements of the gas storage facility.

[0007] Optionally, in one embodiment of this application, the temperature-volume correlation model is: , in, The air quality injected into the gas storage tank throughout the entire energy storage process.

This is the specific heat capacity of air at constant pressure.

[0008] Through the aforementioned technical means, the embodiments of this application can use a temperature-volume correlation model to determine the temperature compensation amount caused by expansion and heat loss during the energy storage and release cycle of the gas storage tank. This allows for the determination of the inlet temperature benchmark value of the target gas storage tank, which can accurately compensate for the temperature loss of the gas storage tank. This effectively avoids the temperature inside the tank being continuously lower than the design value or fluctuating frequently and significantly during long-term operation, thereby reducing problems such as shrinkage cracking and ice expansion damage of the sealing layer due to low temperature, reducing the risk of high-pressure air leakage, and extending the service life of the gas storage tank. At the same time, it can provide a clear target for compressor inlet temperature regulation, ensuring the performance and structural stability of the gas storage tank sealing layer material, improving the operational reliability of the compressed air energy storage system, reducing system maintenance costs, and helping the system adapt to the needs of renewable energy consumption and grid stable operation.

[0009] Optionally, in one embodiment of this application, generating the set value of the compression-side heat exchange medium flow rate includes: measuring the compressor outlet temperature; and generating the final set value of the compression-side heat exchange medium flow rate based on the compressor outlet temperature, combined with heat exchanger parameters, and according to the heat balance equation, wherein the calculation formula for the set value is: , in, For the flow rate of the heat exchange medium on the compression side, This refers to the mass flow rate of the air exiting the compressor. and These are the specific heat capacities at constant pressure for air and the heat exchange medium, respectively. This refers to the actual temperature of the air exiting the compressor. and These are the inlet and outlet temperatures of the heat exchange medium in the heat exchanger. For heat exchanger efficiency.

[0010] Through the above-mentioned technical means, the embodiments of this application can determine the final set value of the heat exchange medium flow rate on the compression side based on the measured compressor outlet temperature value and relevant parameters of the heat exchanger using the heat balance equation. This allows the set value of the heat exchange medium flow rate to closely match the dynamic operating conditions of the gas storage tank (such as changes in air quality and pressure fluctuations) and the actual load of the compressor, accurately controlling the compressor outlet temperature to remain stable within the target range. This avoids overheating or energy waste caused by improper flow, ensures the accurate implementation of the gas storage tank inlet temperature benchmark value, reduces damage to the sealing layer caused by temperature fluctuations, and ultimately improves the heat exchange efficiency on the compression side and the overall stability and economy of the compressed air energy storage system.

[0011] Optionally, in one embodiment of this application, the method further includes: calculating the deviation between the actual end-of-cycle temperature of the target gas storage facility and the preset target temperature after each storage-release cycle; using the deviation to correct the temperature compensation amount of the temperature-volume correlation model, so as to fine-tune the inlet temperature reference value of the target gas storage facility using the corrected temperature compensation amount.

[0012] Through the above-mentioned technical means, the embodiments of this application can calibrate the temperature compensation amount by temperature deviation, thereby fine-tuning the reference value of the gas storage inlet temperature, avoiding the accumulation of deviations during long-term operation, and ensuring that the temperature control always meets the lifespan requirements.

[0014] Through the aforementioned technical means, the embodiments of this application can dynamically capture the temperature change trend on the compression side and the difference in heat exchange demand by monitoring the operating parameters of the temperature control loop (such as the compressor inlet / outlet air temperature, the inlet and outlet temperatures of the heat exchange medium, and the real-time temperature of the gas storage tank). This makes the generated set value of the heat exchange medium flow rate on the compression side more closely match the actual working conditions, which can avoid energy waste caused by excessive flow and prevent compressed air overheating caused by insufficient flow (affecting the safety of subsequent gas storage). At the same time, it can correct heat exchange deviations in real time, ensuring that the compressor outlet temperature is stable within the target range, indirectly ensuring the accurate implementation of the gas storage tank inlet temperature benchmark value, reducing the damage to the sealing layer caused by temperature fluctuations, and ultimately improving the heat exchange efficiency of the compression system and the overall stability and economy of the compressed air energy storage system.

[0015] A second aspect of this application provides a gas storage inlet temperature control system considering the lifespan of the gas storage facility, comprising: a determination module, which determines a temperature compensation amount for the inlet temperature of a target gas storage facility based on a pre-built temperature-volume correlation model, and determines a reference value for the inlet temperature of the target gas storage facility based on the temperature compensation amount, wherein the temperature-volume correlation model of the gas storage facility is constructed from historical operating data of gas storage facilities of different volumes; a generation module, which generates a flow rate setpoint for the compression-side heat exchange medium based on the reference value for the inlet temperature and operating parameters of the temperature control loop; and a control module, which compares the setpoint with the actual flow rate of the compression-side heat exchange medium to obtain a flow rate deviation, calculates the change in the opening of the flow regulating valve of the compression-side heat exchange system based on the flow rate deviation, adjusts the valve opening of the flow regulating valve based on the change in opening, and adjusts the outlet temperature of the compressor based on the real-time pressure at the inlet of the target gas storage facility, thereby controlling the inlet temperature of the target gas storage facility through pressure-temperature coupling regulation.

[0016] By employing the aforementioned technical means, the reference value for the gas storage inlet temperature can be determined by combining the "temperature-volume correlation model" with the lifespan requirements of the gas storage facility. Based on this reference value, the flow rate setpoint of the heat exchange medium on the compression side can be derived by combining the key operating parameters of the control system acquired in real time. Furthermore, based on this setpoint, the opening of the flow regulating valve can be automatically adjusted by the secondary loop controller, and the compressor outlet temperature can be corrected by implementing pressure. This ensures that the compressor outlet temperature meets the gas storage facility inlet temperature requirements, thus ensuring that temperature control conforms to the lifespan requirements of the gas storage facility.

[0017] Optionally, in one embodiment of this application, the temperature-volume correlation model is: ， in, The air quality injected into the gas storage tank throughout the entire energy storage process. To maintain the original air quality inside the gas storage facility, The temperature of the air injected into the gas storage tank during the entire energy storage process. The initial temperature inside the gas storage facility. This refers to the air temperature inside the gas storage tank after the energy storage process has ended. This is the specific heat capacity of air at constant pressure.

[0018] Through the aforementioned technical means, the embodiments of this application can use a temperature-volume correlation model to determine the temperature compensation amount caused by expansion and heat loss during the energy storage and release cycle of the gas storage tank. This allows for the determination of the inlet temperature benchmark value of the target gas storage tank, which can accurately compensate for the temperature loss of the gas storage tank. This effectively avoids the temperature inside the tank being continuously lower than the design value or fluctuating frequently and significantly during long-term operation, thereby reducing problems such as shrinkage cracking and ice expansion damage of the sealing layer due to low temperature, reducing the risk of high-pressure air leakage, and extending the service life of the gas storage tank. At the same time, it can provide a clear target for compressor inlet temperature regulation, ensuring the performance and structural stability of the gas storage tank sealing layer material, improving the operational reliability of the compressed air energy storage system, reducing system maintenance costs, and helping the system adapt to the needs of renewable energy consumption and grid stable operation.

[0019] Optionally, in one embodiment of this application, the generation module includes: a measurement unit for measuring the outlet temperature of the compressor; and a generation unit for generating a final set value for the flow rate of the heat exchange medium on the compression side based on the outlet temperature of the compressor and in conjunction with heat exchanger parameters, according to a heat balance equation, wherein the formula for calculating the set value is: ， in, For the flow rate of the heat exchange medium on the compression side, This refers to the mass flow rate of the air exiting the compressor. and These are the specific heat capacities at constant pressure for air and the heat exchange medium, respectively. This refers to the actual temperature of the air exiting the compressor. and These are the inlet and outlet temperatures of the heat exchange medium in the heat exchanger. For heat exchanger efficiency.

[0020] Through the above-mentioned technical means, the embodiments of this application can determine the final set value of the heat exchange medium flow rate on the compression side based on the measured compressor outlet temperature value and relevant parameters of the heat exchanger using the heat balance equation. This allows the set value of the heat exchange medium flow rate to closely match the dynamic operating conditions of the gas storage tank (such as changes in air quality and pressure fluctuations) and the actual load of the compressor, accurately controlling the compressor outlet temperature to remain stable within the target range. This avoids overheating or energy waste caused by improper flow, ensures the accurate implementation of the gas storage tank inlet temperature benchmark value, reduces damage to the sealing layer caused by temperature fluctuations, and ultimately improves the heat exchange efficiency on the compression side and the overall stability and economy of the compressed air energy storage system.

[0021] Optionally, in one embodiment of this application, it further includes: a calculation module, used to calculate the deviation between the actual end temperature of the target gas storage and the preset target temperature after each storage-release cycle; and an adjustment module, used to correct the temperature compensation amount of the temperature-volume correlation model using the deviation, so as to fine-tune the inlet temperature reference value of the target gas storage using the corrected temperature compensation amount.

[0022] Through the above-mentioned technical means, the embodiments of this application can calibrate the temperature compensation amount by temperature deviation, thereby fine-tuning the reference value of the gas storage inlet temperature, avoiding the accumulation of deviations during long-term operation, and ensuring that the temperature control always meets the lifespan requirements.

[0024] Through the aforementioned technical means, the embodiments of this application can dynamically capture the temperature change trend on the compression side and the difference in heat exchange demand by monitoring the operating parameters of the temperature control loop (such as the compressor inlet / outlet air temperature, the inlet and outlet temperatures of the heat exchange medium, and the real-time temperature of the gas storage tank). This makes the generated set value of the heat exchange medium flow rate on the compression side more closely match the actual working conditions, which can avoid energy waste caused by excessive flow and prevent compressed air overheating caused by insufficient flow (affecting the safety of subsequent gas storage). At the same time, it can correct heat exchange deviations in real time, ensuring that the compressor outlet temperature is stable within the target range, indirectly ensuring the accurate implementation of the gas storage tank inlet temperature benchmark value, reducing the damage to the sealing layer caused by temperature fluctuations, and ultimately improving the heat exchange efficiency of the compression system and the overall stability and economy of the compressed air energy storage system.

Detailed Implementation

[0030] The embodiments of this application are described in detail below. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this application, and should not be construed as limiting this application.

[0031] The following describes a gas storage inlet temperature control method and system considering the lifespan of the gas storage facility, based on embodiments of this application, with reference to the accompanying drawings. Addressing the problem mentioned in the background art where air expansion and heat loss cause gas storage temperature decay, affecting the performance of the sealing layer material and structural stability, thus shortening the gas storage facility's lifespan, this application provides a gas storage inlet temperature control method considering the gas storage facility's lifespan. In this method, a reference value for the gas storage facility inlet temperature is determined by combining a "temperature-volume correlation model" with the gas storage facility's lifespan requirements. Based on this reference value, a setpoint for the flow rate of the heat exchange medium on the compression side is derived using key operating parameters of the control system acquired in real time. Then, based on this setpoint, the opening of the flow regulating valve is automatically adjusted by the secondary loop controller, and the compressor outlet temperature is corrected by real-time pressure, ensuring that the compressor outlet temperature meets the gas storage facility inlet temperature requirements and that temperature control aligns with the gas storage facility's lifespan requirements. This solves the problem in related technologies where air expansion and heat loss cause gas storage temperature decay, affecting the performance of the sealing layer material and structural stability, thus shortening the gas storage facility's lifespan.

[0032] Specifically, Figure 1 This is a schematic flowchart illustrating a gas storage inlet temperature control method that considers the lifespan of the gas storage facility, as provided in an embodiment of this application.

[0033] like Figure 1 As shown, the gas storage inlet temperature control method considering the gas storage facility's lifespan includes the following steps: In step S101, the temperature compensation amount of the inlet temperature of the target gas storage is determined based on the pre-built temperature-volume correlation model, and the reference value of the inlet temperature of the target gas storage is determined according to the temperature compensation amount. The temperature-volume correlation model of the gas storage is constructed from the historical operating data of gas storages of different volumes.

[0034] The inlet temperature benchmark can be understood as the target inlet temperature standard value set by the compressor to input air into the gas storage facility. This is to offset the temperature drop caused by air expansion and heat loss during the long-term energy storage and release cycle of the gas storage facility, ensuring that the temperature inside the facility remains stable within the design range (avoiding sealing layer failure and structural damage). Essentially, it is a "temperature compensation benchmark." It can be determined based on the temperature compensation amount (i.e., the temperature loss ΔT_loss over one storage and release cycle of the gas storage facility). Let's assume the calculation formula is simplified to T_loss. 基 = T 设计 + ΔT 损 - ΔT 温降 (T) 设计 The design operating temperature for the gas storage facility, ΔT 温降(This refers to the natural temperature drop during air transport). For example, when the design temperature is 30℃, the compensation is 8℃, and the transport temperature drop is 2℃, the reference value is 36℃. It can solve the problem of temperature accumulation and decay, ensure system stability, and guide compressor operation. It is the core basis of the temperature compensation control strategy.

[0035] Optionally, in one embodiment of this application, the temperature-volume correlation model is: ， in, The air quality injected into the gas storage tank throughout the entire energy storage process. To maintain the original air quality inside the gas storage facility, The temperature of the air injected into the gas storage tank during the entire energy storage process. The initial temperature inside the gas storage facility. This refers to the air temperature inside the gas storage tank after the energy storage process has ended. This is the specific heat capacity of air at constant pressure.

[0036] Compared to salt cavern compressed air energy storage systems, when using artificial chambers to store compressed air, the temperature of the storage tank decreases after each storage-release cycle due to the relatively small volume. The smaller the volume of the artificial chamber, the more significant the temperature drop. When a compressed air energy storage power station operates multiple times a day, the continuously decreasing storage tank temperature affects both the lifespan of the storage tank and the inlet temperature of the turbine system, thus impacting its operating efficiency. Therefore, rather than addressing localized problems, the storage tank inlet temperature control method proposed in this application focuses more on the overall temperature of the storage tank, and thus employs a one-dimensional model.

[0037] In actual implementation, the embodiments of this application can construct a "volume-temperature compensation" relationship based on historical operating data (the periodic temperature change pattern of different volume gas storage facilities) to address the temperature decay differences of gas storage facilities with different volumes. Small volume gas storage facilities (such as artificial caverns and small ground storage tanks) have a large heat exchange area and a fast temperature decay rate, so the model outputs a larger temperature compensation amount; large volume gas storage facilities (such as large salt caverns and underground storage tanks) have a relatively slow temperature decay, so the model outputs a smaller compensation amount.

[0038] The above model can calculate the theoretical temperature value of the gas storage tank after the current injection process is completed. By comparing this value with the set temperature value of the gas storage tank, it can be determined whether the temperature of the injected gas needs to be adjusted, thereby obtaining the temperature compensation amount.

[0039] Furthermore, in this embodiment of the application, the inlet temperature reference value can be determined by combining the "temperature-volume correlation model" with the gas storage facility's lifespan requirements (the temperature stability range that the sealing layer can withstand): For example, the goal can be "the temperature fluctuation of the gas storage tank does not exceed the set value after one storage and release cycle"; based on the model, the volume compensation amount can be further determined, and combined with the gas storage tank design temperature (such as the optimal temperature range for maintaining the performance of the sealing layer), the initial inlet temperature reference value can be obtained; the reference value needs to be adapted to the capacity of the compression side system to ensure that the compressor outlet temperature can be adjusted to the inlet temperature corresponding to the reference through the heat exchange system.

[0040] The volume compensation amount refers to the temperature compensation value for gas storage facilities of different volumes. The temperature drop value after one storage-release cycle is different for different volumes of gas storage facilities. The initial inlet temperature reference value refers to the inlet temperature reference value of the gas storage facility, which is the control target.

[0041] Based on the "temperature-volume correlation model," it can be determined whether the gas storage temperature can reach the set value after completing the gas storage process at the current temperature and mass flow rate. If it cannot, temperature compensation is required. To ensure the safe operation of the gas storage facility in the next cycle, the temperature rise at the gas storage inlet varies depending on the volume of the storage facility after one storage-release cycle. Therefore, the temperature compensation amount can be designed based on the actual operating conditions of the gas storage facility. This compensation amount can be used to determine the inlet temperature reference value in subsequent steps. This is to offset the temperature decay during the storage-release cycle.

[0042] The formula for calculating the inlet temperature reference value can be set as follows: , In the formula, This indicates the originally set inlet temperature of the gas storage facility.

[0043] Through the aforementioned technical means, the embodiments of this application can use a temperature-volume correlation model to determine the temperature compensation amount caused by expansion and heat loss during the energy storage and release cycle of the gas storage tank. This allows for the determination of the inlet temperature benchmark value of the target gas storage tank, which can accurately compensate for the temperature loss of the gas storage tank. This effectively avoids the temperature inside the tank being continuously lower than the design value or fluctuating frequently and significantly during long-term operation, thereby reducing problems such as shrinkage cracking and ice expansion damage of the sealing layer due to low temperature, reducing the risk of high-pressure air leakage, and extending the service life of the gas storage tank. At the same time, it can provide a clear target for compressor inlet temperature regulation, ensuring the performance and structural stability of the gas storage tank sealing layer material, improving the operational reliability of the compressed air energy storage system, reducing system maintenance costs, and helping the system adapt to the needs of renewable energy consumption and grid stable operation.

[0044] In step S102, the flow rate setpoint of the heat exchange medium on the compression side is generated based on the inlet temperature reference value and the operating parameters of the temperature control loop.

[0045] Among them, the flow rate setpoint of the heat exchange medium on the compression side refers to the standard value of the flow rate per unit time of the medium (such as cooling water, heat transfer oil, etc.) used for heat exchange with compressed air during the compression stage of the compressed air energy storage system in order to control the temperature of the air at the compressor outlet and meet the subsequent gas storage or process requirements. It can be determined by combining parameters such as compressor load, air inlet and outlet temperature target, and heat exchange efficiency to achieve precise temperature control and ensure stable operation of the compression system.

[0046] Optionally, in one embodiment of this application, the operating parameters of the temperature control loop include: temperature parameter data of at least one loop; heat exchanger parameter data of at least one loop; pressure parameter data of at least one loop; load and flow parameter data of at least one loop; and deviation parameter data of at least one loop.

[0047] In this embodiment, the temperature control loop of the gas storage tank can be set as a main and auxiliary loop coordinated control. Based on the monitored real-time operating parameters and the gas storage tank temperature-volume model, the inlet temperature can be accurately controlled through the coordination of the main and auxiliary loops.

[0048] Specifically, after the main loop control system is put into operation in the gas storage temperature control loop, the following parameters can be obtained in real time through the parameter acquisition system: Temperature parameters: such as gas storage inlet temperature, compressor outlet temperature, etc.; Heat exchanger parameters: such as the specific heat capacity of the heat exchange medium at constant pressure, heat exchanger efficiency, etc. Pressure parameters: such as the gas storage inlet pressure (to capture pressure fluctuations for subsequent temperature correction), etc. Load and flow parameters: such as motor power (used to reflect compressor load), flow rate of heat exchange medium on the compression side (which can be used as a basis for adjustment at the actuator level), etc. Deviation parameters: such as the deviation between the set value and the actual value of the gas storage temperature, the deviation between the set value and the actual value of the compressor outlet temperature, etc.

[0049] This application embodiment can dynamically capture the temperature change trend on the compression side and the difference in heat exchange demand by monitoring the operating parameters of the temperature control loop (such as the compressor inlet / outlet air temperature, the constant pressure specific heat capacity of the heat exchange medium, and the real-time temperature of the gas storage tank). This makes the generated set value of the heat exchange medium flow rate on the compression side more closely match the actual working conditions. It can avoid energy waste caused by excessive flow and prevent compressed air overheating caused by insufficient flow (affecting the safety of subsequent gas storage). At the same time, it can correct heat exchange deviations in real time, ensuring that the compressor outlet temperature is stable within the target range. This indirectly ensures that the reference value of the gas storage tank inlet temperature is accurately implemented, reduces the damage of temperature fluctuations to the sealing layer, and ultimately improves the heat exchange efficiency of the compression system and the overall stability and economy of the compressed air energy storage system.

[0050] Furthermore, in one embodiment of this application, generating a set value for the flow rate of the heat exchange medium on the compression side includes: measuring the outlet temperature of the compressor; and generating the final set value for the flow rate of the heat exchange medium on the compression side based on the compressor outlet temperature, combined with the heat exchanger parameters, and according to the heat balance equation, wherein the calculation formula for the set value is: ， In the formula, For the flow rate of the heat exchange medium on the compression side, This refers to the mass flow rate of the air exiting the compressor. and These are the specific heat capacities at constant pressure for air and the heat exchange medium, respectively. This refers to the actual temperature of the air exiting the compressor. and These are the inlet and outlet temperatures of the heat exchange medium in the heat exchanger. For heat exchanger efficiency.

[0051] The inlet temperature control loop of the gas storage facility can be built based on a PLC controller. It has a built-in "temperature-volume correlation model" and main loop setpoint calculation logic. It receives the collected monitoring data in real time and outputs the setpoint of the heat exchange medium flow rate. It is the core computing unit of the main loop.

[0052] As one possible approach, embodiments of this application can be configured to generate a set value for the final flow rate of the heat exchange medium on the compression side in the main control loop. For example, the set value for the flow rate of the heat exchange medium on the compression side can be derived by combining the measured value of the compressor outlet temperature, the reference value of the gas storage tank inlet temperature, and the heat exchange capacity of the heat exchange medium.

[0053] Specifically, in this embodiment, the outlet temperature of the compressor can first be measured by a temperature sensor. The outlet temperature of the compressor, the relevant parameters of the heat exchanger, and the reference value of the gas storage tank inlet temperature obtained above are input into the heat balance equation model to obtain the final set value of the flow rate of the heat exchange medium on the compression side.

[0054] In summary, the technical solution described above can be roughly divided into three steps. The first step is to determine whether the gas storage temperature can meet the operating conditions after the gas is injected, based on the current gas storage temperature. The second step is to determine the required gas storage inlet temperature if the conditions are not met. This step determines the temperature compensation value, which is mainly based on actual engineering conditions. The third step is to derive the mass flow rate of the heat exchange medium. This can be calculated based on the compressor outlet temperature and the gas storage inlet temperature obtained in the second step. After obtaining the heat exchange medium flow rate value, the mass flow rate of the heat exchanger is corrected by adjusting the specific equipment.

[0055] Through the above-mentioned technical means, the embodiments of this application can determine the final set value of the heat exchange medium flow rate on the compression side based on the measured compressor outlet temperature value and relevant parameters of the heat exchanger using the heat balance equation. This allows the set value of the heat exchange medium flow rate to closely match the dynamic operating conditions of the gas storage tank (such as changes in air quality and pressure fluctuations) and the actual load of the compressor, accurately controlling the compressor outlet temperature to remain stable within the target range. This avoids overheating or energy waste caused by improper flow, ensures the accurate implementation of the gas storage tank inlet temperature benchmark value, reduces damage to the sealing layer caused by temperature fluctuations, and ultimately improves the heat exchange efficiency on the compression side and the overall stability and economy of the compressed air energy storage system.

[0056] In step S103, the set value is compared with the actual flow rate of the heat exchange medium on the compression side to obtain the flow deviation. Based on the flow deviation, the change in the opening of the flow regulating valve of the heat exchange system on the compression side is calculated. The valve opening of the flow regulating valve is adjusted based on the change in opening. The outlet temperature of the compressor is adjusted based on the real-time pressure at the inlet of the target gas storage tank. The inlet temperature of the target gas storage tank is controlled through pressure-temperature coupling regulation.

[0057] In actual power plant operation, gas volume control needs to be constrained by the grid's demand for power generation. The controlled object in this embodiment is the heat exchange medium flow rate. The gas storage inlet temperature is calculated based on the real-time temperature of the gas storage tank. By adjusting the heat exchanger medium flow rate and considering the compressor outlet air temperature, the gas storage temperature variation is kept within an acceptable range. This control process does not affect the power plant's gas volume response to grid dispatch demands.

[0058] This step corresponds to the secondary loop control in the main and secondary loop coordinated temperature control. After the main loop generates the flow setpoint of the heat exchange medium on the compression side, the secondary loop further regulates the compressor outlet temperature.

[0059] Specifically, such as Figure 2 As shown, the flow rate setpoint of the heat exchange medium on the compression side can be sent to the secondary loop PID controller to compare the deviation between the actual flow rate and the setpoint. The PID controller calculates the change in the opening of the flow regulating valve of the heat exchange system and automatically adjusts the valve opening to adjust the flow rate of the heat exchange medium to the target flow rate as much as possible. Simultaneously, real-time pressure correction is combined. When the pressure is lower than the setpoint, the compressor outlet temperature is appropriately increased (to compensate for the heat dissipation of air expansion). When the pressure is higher than the setpoint, the outlet temperature is appropriately decreased (to avoid adiabatic compression heating). This achieves pressure-temperature coupled regulation, which can ensure that the compressor outlet parameters are stable and adapted to the working conditions of the air storage tank, and reduce the damage to the sealing layer caused by temperature and pressure fluctuations, thereby improving the accuracy and reliability of the compressed air energy storage system.

[0060] Optionally, in one embodiment of this application, the method further includes: calculating the deviation between the actual end temperature of the target gas storage tank and the preset target temperature after each storage-release cycle; using the deviation to correct the temperature compensation amount of the temperature-volume correlation model, so as to fine-tune the inlet temperature reference value of the target gas storage tank using the corrected temperature compensation amount.

[0061] This application embodiment also considers the special situation where the actual temperature decay is greater than expected during actual operation. After each storage and release cycle, temperature deviation calibration is performed to ensure long-term control accuracy: the actual temperature at the end of the gas storage cycle is compared with the target temperature (fluctuation ±2℃), and the deviation is calculated; the compensation amount of the "temperature-volume correlation model" is corrected based on the deviation (if the actual decay is greater than expected, the compensation amount of the corresponding volume is increased); the reference value of the gas storage inlet temperature is finely adjusted to avoid the accumulation of deviation during long-term operation and to ensure that the temperature control always meets the lifespan requirements.

[0062] In summary, the inlet temperature control method proposed in this application can be achieved through five steps: "model construction - benchmark determination - real-time monitoring - dynamic adjustment - feedback calibration". This method is applicable to compressed air energy storage systems such as artificial chamber gas storage facilities and ground storage tanks of different volumes. By accurately controlling the inlet temperature of the gas storage facility, the temperature of the gas storage and release cycle can be kept stable, thus extending the service life.

[0063] The gas storage inlet temperature control method proposed in this application, which considers the lifespan of the gas storage facility, determines a reference value for the gas storage inlet temperature by combining a "temperature-volume correlation model" with the lifespan requirements of the gas storage facility. Based on this reference value, and combined with the key operating parameters of the control system acquired in real time, the setpoint for the flow rate of the heat exchange medium on the compression side is derived. Then, based on this setpoint, the opening of the flow regulating valve is automatically adjusted by the secondary loop controller, and the compressor outlet temperature is corrected by combining real-time pressure, so that the compressor outlet temperature can meet the gas storage inlet temperature requirements, ensuring that the temperature control conforms to the lifespan requirements of the gas storage facility. This solves the problems in related technologies where the gas storage temperature decays due to factors such as air expansion and energy release, and heat loss, which in turn affects the performance and structural stability of the sealing layer material, leading to a shortened lifespan of the gas storage facility.

[0064] Next, refer to the appendix. Figure 3 This application describes a gas storage inlet temperature control system that takes into account the lifespan of the gas storage facility, based on an embodiment of this application.

[0065] Figure 3 This is a block diagram of a gas storage inlet temperature control system that takes into account the lifespan of the gas storage facility according to an embodiment of this application.

[0066] like Figure 3 As shown, the gas storage inlet temperature control system 10, which takes into account the lifespan of the gas storage facility, includes: a determination module 100, a generation module 200, and a control module 300.

[0067] The determination module 100 is used to determine the temperature compensation amount of the inlet temperature of the target gas storage based on the pre-built temperature-volume correlation model, and to determine the inlet temperature benchmark value of the target gas storage based on the temperature compensation amount. The temperature-volume correlation model of the gas storage is constructed from the historical operating data of gas storages of different volumes.

[0068] The generation module 200 is used to generate the flow rate setpoint of the heat exchange medium on the compression side based on the inlet temperature reference value and the operating parameters of the temperature control loop.

[0069] The control module 300 is used to compare the set value with the actual flow rate of the heat exchange medium on the compression side to obtain the flow deviation, and calculate the opening change of the flow regulating valve of the heat exchange system on the compression side based on the flow deviation, so as to adjust the valve opening of the flow regulating valve based on the opening change, and adjust the outlet temperature of the compressor based on the real-time pressure at the inlet of the target gas storage, so as to control the inlet temperature of the target gas storage through pressure-temperature coupling regulation.

[0070] Optionally, in one embodiment of this application, the temperature-volume correlation model is:

[0071] in, The air quality injected into the gas storage tank throughout the entire energy storage process. To maintain the original air quality inside the gas storage facility, The temperature of the air injected into the gas storage tank during the entire energy storage process. The initial temperature inside the gas storage facility. This refers to the air temperature inside the gas storage tank after the energy storage process has ended. This is the specific heat capacity of air at constant pressure.

[0072] Optionally, in one embodiment of this application, the generation module 200 includes: a measurement unit and a generation unit; wherein, the measurement unit is used to measure the outlet temperature value of the compressor; the generation unit is used to generate a final set value of the flow rate of the heat exchange medium on the compression side based on the outlet temperature value of the compressor and in combination with the heat exchanger parameters, according to the heat balance equation, wherein the calculation formula of the set value is:

[0073] in, For the flow rate of the heat exchange medium on the compression side, This refers to the mass flow rate of the air exiting the compressor. and These are the specific heat capacities at constant pressure for air and the heat exchange medium, respectively. This refers to the actual temperature of the air exiting the compressor. and These are the inlet and outlet temperatures of the heat exchange medium in the heat exchanger. For heat exchanger efficiency.

[0074] Optionally, in one embodiment of this application, the gas storage inlet temperature control system 10, which considers the lifespan of the gas storage facility, further includes a calculation module and an adjustment module; wherein, the calculation module is used to calculate the deviation between the actual end temperature of the target gas storage facility and the preset target temperature after each storage and release cycle; the adjustment module is used to correct the temperature compensation amount of the temperature-volume correlation model using the deviation, so as to fine-tune the inlet temperature reference value of the target gas storage facility using the corrected temperature compensation amount.

[0075] Optionally, in one embodiment of this application, the operating parameters of the temperature control loop include: Temperature parameter data for at least one loop; heat exchanger parameter data for at least one loop; pressure parameter data for at least one loop; load and flow rate parameter data for at least one loop; deviation parameter data for at least one loop.

[0076] For example, the above-mentioned control system can take "extending the life of the gas storage facility" as its core objective, and integrate the gas storage system, main loop control system, secondary loop control system, and compression subsystem to form a closed-loop control system, specifically configured as follows: 1. Compression Subsystem It can include a multi-stage compressor (to pressurize the air), a compression-side heat exchange system (to regulate the compressor outlet temperature, with water or heat transfer oil as the medium), and a compression-side heat storage system (to recover waste heat from compression and assist in temperature regulation), providing high-pressure air with controllable temperature for the gas storage facility.

[0077] 2. Main loop control system (decision-making level) The core function is to generate precise temperature control targets (compression-side heat exchange medium flow rate setpoint), which requires obtaining two types of key parameters: Feedforward impact parameters: Real-time dynamic parameters used to predict disturbances in advance, including compressor outlet temperature (directly affecting gas storage inlet temperature) and motor power (reflecting compressor load and indirectly related to outlet temperature fluctuations). Model characteristic parameters: The basic parameters for building the control model, including compressor outlet temperature, heat exchanger parameters, and gas storage inlet temperature reference value.

[0078] The main circuit can be modeled using the above parameters to output the set value of the heat exchange medium flow rate of the compression side heat exchange system, ensuring that the adjustment target matches the lifespan requirements of the gas storage facility and the real-time operating conditions.

[0079] 3. Secondary loop control system (execution layer) Using the "heat exchange medium flow rate setpoint" output from the main loop as the target, precise tracking is achieved through PID closed-loop control: The actual flow rate of the heat exchange medium on the compression side is collected in real time and compared with the set value to obtain the deviation. The PID controller calculates the change in the opening of the flow regulating valve in the compression-side heat exchange system based on the deviation. By adjusting the valve opening to control the flow rate of the heat exchange medium, the compressor outlet temperature is adjusted, and finally the gas storage inlet temperature is stabilized, thus solving the problem of regulation lag caused by the large inertia and large delay of the heat exchange system.

[0080] 4. Parameter Acquisition and Transmission Section Equipped with dedicated sensors and data transmission units: Temperature sensors: 2 (installed at the gas storage inlet and compressor outlet respectively, to monitor core temperature parameters); Pressure sensor: 1 (installed on the inlet pipe of the gas storage tank to capture pressure fluctuations in real time); Flow sensor: 1 (installed on the heat exchange medium pipeline on the compression side to collect the actual flow rate); Power sensor: 1 (installed at the motor outlet to obtain compressor load); Data transmission: 4G / 5G wireless transmission is used to ensure real-time parameter accuracy and support the coordination of main and secondary circuits.

[0081] Furthermore, the control system can be divided into four main functional parts, and the responsibilities and coordination relationships of each part are as follows: 1. Data Acquisition Section: Responsible for real-time acquisition of all parameters, ensuring that the sensor installation location corresponds one-to-one with the monitored object, and controlling the data transmission delay to the millisecond level, providing reliable input for subsequent modules.

[0082] 2. Model Calculation Section: Based on a PLC controller, it has a built-in "temperature-volume correlation model" and main loop setpoint calculation logic. It receives data from the acquisition module in real time and outputs the setpoint of the heat exchange medium flow rate on the compression side. It is the core computing unit of the main loop.

[0083] 3. Deviation handling section: Integrates PID algorithm with pressure-temperature coupled correction logic: handles the deviation between the set value output by the main loop and the actual value collected by the secondary loop; combines real-time pressure to dynamically adjust the correction coefficient and output valve opening control command; avoids the defect of ignoring the influence of pressure in single PID regulation.

[0084] 4. Execution control section: Includes an electric flow regulating valve (regulation accuracy up to ±0.1% opening degree) and cascade control program: Receives opening command from deviation processing module to accurately control heat exchange medium flow rate; cascade control logic: the main controller tracks the gas storage inlet temperature deviation, and the secondary controller tracks the heat exchange medium flow rate deviation, providing dual protection for regulation accuracy and adapting to the large inertia characteristics of the heat exchange system.

[0085] It should be noted that the foregoing explanation of the gas storage inlet temperature control method embodiment considering the gas storage life also applies to the gas storage inlet temperature control system of this embodiment considering the gas storage life, and will not be repeated here.

[0086] The gas storage inlet temperature control system proposed in this application, which considers the lifespan of the gas storage facility, determines a reference value for the gas storage inlet temperature by combining a "temperature-volume correlation model" with the gas storage facility's lifespan requirements. Based on this reference value, and combined with key operating parameters of the control system acquired in real time, the setpoint for the flow rate of the heat exchange medium on the compression side is derived. Then, based on this setpoint, the secondary loop controller automatically adjusts the opening of the flow regulating valve and corrects the compressor outlet temperature by combining real-time pressure, ensuring that the compressor outlet temperature meets the gas storage facility inlet temperature requirements and that temperature control aligns with the gas storage facility's lifespan requirements. This solves the problems in related technologies where factors such as air expansion and energy release, and heat loss lead to temperature decay in the gas storage facility, which in turn affects the performance and structural stability of the sealing layer material, resulting in a shortened gas storage facility lifespan.
