Description

Technical Field

[0001] This invention relates to the field of power engineering technology, and in particular to a control method, system, equipment and storage medium for an air-cooled island antifreeze sealing device. Background Technology

[0002] In northern my country, harsh winters bring frigid temperatures that often plummet to extremely low levels. Simultaneously, thermal power units frequently operate under deep peak-shaving conditions. This dual challenge poses a severe test to the stable operation of air-cooled power islands. As a critical heat dissipation component of thermal power units, the tube bundles of air-cooled power islands are highly susceptible to icing in low-temperature environments, especially when the unit is operating at low load. This icing problem not only significantly reduces the heat exchange efficiency of the air-cooled power island, but more seriously, it can lead to tube bundle freezing and cracking, resulting in unplanned unit shutdowns and causing substantial economic losses to power production.

[0003] To effectively address the freezing challenge of air-cooled islands, the industry widely adopts the measure of installing anti-freeze sealing devices at key locations such as the air inlets of the air-cooled island fans, with tarpaulins being a common application. However, traditional tarpaulin control methods have significant drawbacks: their adjustment relies heavily on manual experience and is a "fully open" or "fully closed" operation, lacking precise adjustment strategies. This directly leads to the dilemma of "excessive cooling when the tarpaulin is open, and excessive heating when it is closed," and untimely adjustments increase the risk of tube freezing. Furthermore, tarpaulins are typically over ten meters long, and due to the lack of effective positioning devices, their opening degree is difficult to control precisely, further affecting anti-freeze and energy-saving effects.

[0004] The above content is only used to help understand the technical solution of the present invention and does not represent an admission that the above content is prior art. Summary of the Invention

[0005] The main objective of this invention is to provide a control method, system, equipment, and storage medium for an air-cooled island antifreeze sealing device, aiming to solve the technical problem that traditional tarpaulin control methods rely heavily on manual experience and are difficult to achieve precise control.

[0006] To achieve the above objectives, the present invention provides a control method for an air-cooled island anti-freezing and sealing device, wherein the air-cooled island anti-freezing and sealing device includes a tarpaulin, and the control method for the air-cooled island anti-freezing and sealing device includes: Indoor temperature is collected in real time by temperature sensors placed in key areas inside the air-cooled island. Based on the relationship between the indoor temperature and the target indoor temperature value, and the temperature deviation, the opening command value is output; Based on the opening command value, the air-cooled island antifreeze sealing device is controlled to adjust the opening of the tarpaulin. When the air-cooled island antifreeze sealing device is in the fully open position, the opening value of the corresponding tarpaulin is marked as 0%, and when the air-cooled island antifreeze sealing device is in the fully closed position, the opening value of the corresponding tarpaulin is marked as 100%.

[0007] In one embodiment, the step of outputting the opening command value based on the relationship between the indoor temperature and the target indoor temperature value and the temperature deviation includes: The direction of the opening adjustment is determined based on the relationship between the indoor temperature and the target indoor temperature value; The opening control amount is determined based on the temperature deviation between the indoor temperature and the target indoor temperature value; The opening command value is output based on the opening adjustment direction and the opening control quantity.

[0008] In one embodiment, determining the opening adjustment direction based on the relationship between the indoor temperature and the target indoor temperature includes: If the indoor temperature is lower than the target indoor temperature value, then the opening adjustment direction is determined to be decreasing the tarpaulin opening (i.e., adjusting the tarpaulin towards the closing direction); If the indoor temperature is greater than the target indoor temperature value, then the opening adjustment direction is determined to be increasing or decreasing the tarpaulin opening (i.e., adjusting the tarpaulin in the opening direction).

[0009] In one embodiment, determining the opening control amount based on the temperature deviation between the indoor temperature and the target indoor temperature includes: The opening control quantity is calculated using a PID control algorithm based on the temperature deviation between the indoor temperature and the target indoor temperature value. The calculation formula is as follows: ,in, For opening control quantity, For temperature deviation, , , These are the proportional, integral, and differential coefficients, respectively.

[0010] In one embodiment, the step of performing control operations on the air-cooled island antifreeze sealing device based on the opening command value to adjust the opening of the tarpaulin includes: The opening command value is compared with the current opening of the tarpaulin, and the opening difference between the opening command value and the current opening of the tarpaulin is obtained. The operating time is determined based on the opening difference and the unit time opening adjustment value. The time it takes for the air-cooled island antifreeze sealing device to move from the fully open to the fully closed position is T. Therefore, the unit time opening adjustment value is 100% / T = C%. Based on the running time and comparison results, control operations are performed on the air-cooled island antifreeze sealing device to adjust the opening of the tarpaulin.

[0011] In one embodiment, the step of performing control operations on the air-cooled island antifreeze sealing device based on the running time and comparison results to adjust the opening of the tarpaulin includes: If the opening command value is greater than the current opening of the tarpaulin, the air-cooled island antifreeze sealing device is controlled to operate in the closing direction based on the running time, so as to increase the current opening of the tarpaulin.

[0012] In one embodiment, the method includes: If the opening command value is less than the current opening of the tarpaulin, the air-cooled island antifreeze sealing device is controlled to run in the opening direction based on the running time, so as to reduce the current opening of the tarpaulin.

[0013] Furthermore, to achieve the above objectives, the present invention also proposes a control system for an air-cooled island antifreeze sealing device, the control system comprising: The data acquisition module is used to collect indoor temperature in real time through temperature sensors placed in key areas inside the air-cooled island; The calculation module is used to output the opening command value based on the relationship between the indoor temperature and the target indoor temperature value and the temperature deviation. The control module is used to perform control operations on the air-cooled island antifreeze sealing device based on the opening command value, so as to adjust the opening of the tarpaulin. When the air-cooled island antifreeze sealing device is in the fully open position, the opening value of the corresponding tarpaulin is marked as 0%, and when the air-cooled island antifreeze sealing device is in the fully closed position, the opening value of the corresponding tarpaulin is marked as 100%.

[0014] Furthermore, to achieve the above objectives, the present invention also proposes a control device for an air-cooled island antifreeze sealing device. The control device includes: a memory, a processor, and an air-cooled island antifreeze sealing device control program stored in the memory and executable on the processor. The air-cooled island antifreeze sealing device control program is configured to implement the steps of the air-cooled island antifreeze sealing device control method described above.

[0015] In addition, to achieve the above objectives, the present invention also proposes a storage medium storing a control program for an air-cooled island antifreeze sealing device. When the air-cooled island antifreeze sealing device control program is executed by a processor, it implements the steps of the air-cooled island antifreeze sealing device control method described above.

[0016] In this invention, temperature sensors arranged in key areas inside the air-cooled island collect indoor temperature data in real time; based on the relationship and temperature deviation between the indoor temperature and the target indoor temperature, an opening command value is output; based on the opening command value, control operations are performed on the air-cooled island's anti-freeze sealing device to adjust the opening of the tarpaulin. Through this method, the automatic adjustment algorithm of the air-cooled island's anti-freeze sealing device is used to achieve automatic adjustment of the device, and without the need for a positioner, the opening position of the anti-freeze sealing device can be adjusted at any degree, improving control accuracy.

[0018] The realization of the objective, functional features and advantages of the present invention will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0019] It should be understood that the specific embodiments described herein are for illustrative purposes only and are not intended to limit the scope of the invention.

[0020] This invention provides a control method for an air-cooled island antifreeze sealing device, referring to... Figure 1 , Figure 1 This is a flowchart illustrating the first embodiment of the control method for an air-cooled island antifreeze sealing device according to the present invention.

[0021] In this embodiment, the control method for the air-cooled island antifreeze sealing device includes the following steps: Step S10: Real-time acquisition of indoor temperature by temperature sensors placed in key areas inside the air-cooled island.

[0022] In this embodiment, the executing entity is the air-cooled island antifreeze sealing device control equipment. The air-cooled island antifreeze sealing device control equipment has functions such as data processing, data communication, and program execution. The air-cooled island antifreeze sealing device control equipment can be a computer terminal device or other network device, or other devices with similar functions. This embodiment does not limit this.

[0023] It should be noted that, to effectively address the antifreeze challenge of air-cooled islands, the industry widely adopts the measure of installing antifreeze sealing devices at key locations such as the air inlets of the air-cooled island fans, with tarpaulins being a common application. However, traditional tarpaulin control methods have significant drawbacks: their adjustment relies heavily on manual experience and is a "fully open" or "fully closed" operation, lacking a refined adjustment strategy. This directly leads to the dilemma of "excessive cooling when the tarpaulin is open, and excessive heating when it is closed," and untimely adjustment increases the risk of tube freezing. Furthermore, tarpaulins are typically over ten meters long, and due to the lack of effective positioning devices, their opening degree is difficult to control precisely, further affecting antifreeze and energy-saving effects.

[0024] To address the aforementioned technical issues, this embodiment utilizes temperature sensors strategically placed within key areas of the air-cooled island to collect real-time indoor temperature data. Based on the relationship and temperature deviation between the indoor temperature and a target value, an opening command value is output. This command value is then used to control the anti-freezing sealing device of the air-cooled island, adjusting the opening of the tarpaulin. By employing this method, an automatic adjustment algorithm for the anti-freezing sealing device is used to achieve automatic adjustment. Furthermore, without the need for a positioner, the opening position of the anti-freezing sealing device can be adjusted arbitrarily, improving control accuracy. Specifically, this can be implemented as follows.

[0025] In this embodiment, temperature sensors are arranged in key areas inside the air-cooled island to collect indoor temperature data in real time. The placement and number of temperature sensors are not limited in this embodiment and can be adjusted adaptively according to actual conditions.

[0026] In this embodiment, suitable hardware devices are required to implement the automatic adjustment algorithm. For example, the temperature sensors are of high precision and stability, and are evenly deployed in key areas inside the air-cooled island, such as at a height of 1.5 meters in the fan room, to accurately collect indoor temperature data. The control unit uses a programmable logic controller (PLC or integrated into a DCS), which offers advantages such as high reliability and flexible programming. The PLC (or DCS) receives the temperature signal transmitted by the temperature sensor through an analog input module, performs calculations through its internal PID program, and then controls the forward and reverse rotation and running time of the tarpaulin motor via a digital output module. The tarpaulin motor is an AC motor with a certain torque and constant speed, connected to the PLC output via a contactor to achieve motor start / stop and direction control. Simultaneously, to ensure safe system operation, thermal relays and other protection devices are installed to provide overload protection for the motor.

[0027] Furthermore, the software design is implemented using ladder logic in PLC programming software, or programmed in a DCS system using SAMA diagrams. First, a temperature data acquisition program is developed to achieve real-time reading and processing of data from various temperature sensors. Then, a control program is written based on the "time-opening" algorithm and PID control algorithm. In the control program, the acquired indoor temperature is compared with the set target temperature. The PID calculation determines the adjustment amount for the tarpaulin opening, and the "time-opening" algorithm converts this adjustment amount into a motor running time control signal, which is then output to the motor control loop. In addition, a human-machine interface (HMI) communication program is also required. This program displays the air-cooled island's temperature data and tarpaulin opening status on the HMI in real time, facilitating monitoring and parameter setting by operators. The HMI also has an alarm function, promptly issuing audible and visual alarm signals when the temperature exceeds the set safe range or when a system malfunction occurs.

[0028] Step S20: Output the opening command value based on the relationship between the indoor temperature and the target indoor temperature and the temperature deviation.

[0029] In the specific implementation, an opening command value can be further output based on the indoor temperature and the target indoor temperature value. Specifically, the opening adjustment direction is determined based on the relationship between the indoor temperature and the target indoor temperature value; the opening control quantity is determined based on the temperature deviation between the indoor temperature and the target indoor temperature value; and the opening command value is output based on the opening adjustment direction and the opening control quantity.

[0030] Furthermore, if the indoor temperature is lower than the target indoor temperature value, the tarpaulin opening is adjusted to increase; if the indoor temperature is higher than the target indoor temperature value, the tarpaulin opening is adjusted to decrease.

[0031] It should be noted that the opening direction of the tarpaulin is to increase its opening (i.e., adjust the tarpaulin towards the closed direction), and the opening direction of the tarpaulin is to decrease its opening (i.e., adjust the tarpaulin towards the open direction). When the sensor detects that the indoor temperature is lower than the target value, the automatic adjustment system quickly activates, controlling the anti-freeze sealing device (tarpaulin): by increasing the tarpaulin opening or decreasing its closing degree, the system reduces the flow of cold air, thereby quickly raising the indoor temperature and avoiding the risk of frost damage. Conversely, when the indoor temperature is higher than the target value, the system correspondingly decreases the tarpaulin opening, increasing the amount of cold air entering. This prevents the temperature inside the air-cooled island from becoming too high and affecting the normal operation of the unit, while also achieving an energy-efficient and high-performance operating state.

[0032] Furthermore, the opening control quantity can be obtained using a PID control algorithm. The calculation formula in this embodiment is as follows: ,in, For opening control quantity, For temperature deviation, , , These are the proportional, integral, and derivative coefficients, respectively. Finally, by combining the two parameters mentioned above, the final opening command value can be obtained. For example, assuming the control quantity is 40% and the opening value is based on the fully open or fully closed position, if the adjustment direction is to increase the tarpaulin opening, the corresponding opening command value can be 40%; if the adjustment direction is to decrease the tarpaulin opening, the corresponding opening command value can be 60%.

[0033] The PID control algorithm is the core of the automatic adjustment system of the air-cooled island anti-freezing sealing device. To meet the adjustment requirements of this device, the PID parameters need to be optimized—the proportional coefficient (Kp) directly determines the adjustment response speed, the integral coefficient (Ki) is responsible for eliminating the system's steady-state error, and the derivative coefficient (Kd) achieves proactive adjustment by predicting system change trends. In the specific control logic, the system uses the difference between the indoor temperature setpoint and the actual measured value as the deviation input, which is then processed by the PID algorithm to output a control quantity, thereby adjusting the tarpaulin opening. To further improve control accuracy and operational stability, the aforementioned PID parameters need to be finely optimized and adjusted.

[0034] Furthermore, a 20-minute adjustment cycle is set. This is determined by comprehensively considering the thermal inertia of the air-cooled island, the slowness of temperature changes, and improving the reliability of the adjustment device. If the adjustment cycle is too short, the system may adjust the tarpaulin opening too frequently, leading to accelerated wear on motors and other equipment, and may also cause system oscillations; while if the adjustment cycle is too long, it will not be able to respond to temperature changes in a timely manner, affecting the antifreeze effect. Adjusting every 20 minutes ensures that the system has sufficient response speed to temperature changes while avoiding excessively frequent equipment operation.

[0035] Step S30: Perform control operation on the air-cooled island antifreeze sealing device based on the opening command value to adjust the opening of the tarpaulin.

[0036] In a specific implementation, the process of controlling the air-cooled island antifreeze sealing device involves comparing the opening command value with the current opening of the tarpaulin and obtaining the opening difference between the opening command value and the current opening of the tarpaulin; determining the running time based on the opening difference and the unit time opening adjustment value; and performing control operations on the air-cooled island antifreeze sealing device based on the running time and the comparison result to adjust the opening of the tarpaulin.

[0037] It should be noted that in this embodiment, the time for the air-cooled island antifreeze sealing device to go from the fully open position to the fully closed position is T. Then, the unit time opening adjustment value is 100% / T=C. The running time can be calculated based on the opening difference between the opening command value and the current opening of the tarpaulin, combined with the unit time opening adjustment value.

[0038] In its implementation, when the air-cooled island anti-freezing sealing device is fully open, the corresponding tarpaulin opening value is marked as 0%. When the device is fully closed, the tarpaulin opening value is marked as 100%. Therefore, if the tarpaulin opening needs to be increased, the anti-freezing sealing device is closed; conversely, if the tarpaulin opening needs to be decreased, the device is opened. Specifically, if the opening command value is greater than the current tarpaulin opening, the anti-freezing sealing device is controlled to move towards the closed direction based on the running time to increase the current tarpaulin opening. If the opening command value is less than the current tarpaulin opening, the anti-freezing sealing device is controlled to move towards the open direction based on the running time to decrease the current tarpaulin opening.

[0039] In this embodiment, temperature sensors arranged in key areas inside the air-cooled island collect indoor temperature data in real time. Based on the relationship and temperature deviation between the indoor temperature and the target indoor temperature, an opening command value is output. Based on the opening command value, control operations are performed on the air-cooled island's anti-freeze sealing device to adjust the opening of the tarpaulin. Through this method, the automatic adjustment algorithm of the air-cooled island's anti-freeze sealing device is used to achieve automatic adjustment of the device. Furthermore, without the need for a positioner, the opening position of the anti-freeze sealing device can be adjusted at any degree, improving control accuracy.

[0040] Furthermore, this embodiment of the invention also proposes a storage medium storing a control program for an air-cooled island antifreeze sealing device. When the air-cooled island antifreeze sealing device control program is executed by a processor, it implements the steps of the air-cooled island antifreeze sealing device control method described above.

[0041] Reference Figure 2 , Figure 2 This is a structural block diagram of the first embodiment of the air-cooled island antifreeze sealing device control system of the present invention.

[0042] like Figure 2 As shown, the air-cooled island antifreeze sealing device control system proposed in this embodiment of the invention includes: The data acquisition module 10 is used to acquire the indoor temperature in real time by means of temperature sensors arranged in key areas inside the air-cooled island.

When the air-cooled island antifreeze sealing device is in the fully open position, the opening value of the corresponding tarpaulin is marked as 0%, and when the air-cooled island antifreeze sealing device is in the fully closed position, the opening value of the corresponding tarpaulin is marked as 100%.

[0043] In this embodiment, temperature sensors arranged in key areas inside the air-cooled island collect indoor temperature data in real time. Based on the relationship and temperature deviation between the indoor temperature and the target indoor temperature, an opening command value is output. Based on the opening command value, control operations are performed on the air-cooled island's anti-freeze sealing device to adjust the opening of the tarpaulin. Through this method, the automatic adjustment algorithm of the air-cooled island's anti-freeze sealing device is used to achieve automatic adjustment of the device. Furthermore, without the need for a positioner, the opening position of the anti-freeze sealing device can be adjusted at any degree, improving control accuracy.

[0045] In one embodiment, the calculation module 20 is used to determine that if the indoor temperature is less than the target indoor temperature value, the opening adjustment direction is to increase the tarpaulin opening. If the indoor temperature is greater than the target indoor temperature value, then the direction of the opening adjustment is determined to be to reduce the tarpaulin opening.

[0046] If the indoor temperature is lower than the target indoor temperature value, then the direction of the opening adjustment is determined to be to reduce the tarpaulin opening. If the indoor temperature is greater than the target indoor temperature value, then the direction of the opening adjustment is determined to be to increase the tarpaulin opening.

[0047] In one embodiment, the calculation module 20 is used to calculate the opening control quantity based on the temperature deviation between the indoor temperature and the target indoor temperature using a PID control algorithm.

The time it takes for the air-cooled island antifreeze sealing device to move from the fully open to the fully closed position is T. Therefore, the unit time opening adjustment value is 100% / T = C%. Based on the running time and comparison results, control operations are performed on the air-cooled island antifreeze sealing device to adjust the opening of the tarpaulin.

[0049] In one embodiment, the control module 30 is configured to control the air-cooled island antifreeze sealing device to operate in the closing direction based on the running time if the opening command value is greater than the current opening of the tarpaulin, so as to increase the current opening of the tarpaulin.
