Description

Technical Field

[0001] The present invention relates to the field of power systems, and in particular to a transformer substation cooling method and device, and electronic equipment. Background Art

[0002] In the power system, transformers, as key power conversion equipment, play a vital role in the operation of the power grid. Especially in heavy-load areas, the stability and reliability of transformers are directly related to the quality of power supply and the safe operation of the power grid. However, high temperature is one of the main factors affecting the life and performance of transformers. During the peak load period in summer, the load rate of transformers may be as high as 90%, and even close to 100% in some extreme cases. This high-load operation will cause the transformer oil temperature to increase significantly, which in turn accelerates the aging of the insulation material, affects the service life of the transformer, and may even cause serious faults such as insulation breakdown.

[0003] At present, the temperature monitoring and control of transformers mainly rely on traditional equipment such as oil temperature meters and winding temperature meters. Once the oil temperature meter or winding temperature meter fails, the temperature monitoring may fail, resulting in poor cooling effect on the substation.

[0027] In order to enable those skilled in the art to better understand the scheme of the present invention, the technical scheme in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.

[0028] It should be noted that the terms "first", "second", etc. in the specification and claims of the present invention and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the data used in this way can be interchanged where appropriate, so that the embodiments of the present invention described herein can be implemented in an order other than those illustrated or described herein. In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions, for example, a process, method, system, product or device that includes a series of steps or units is not necessarily limited to those steps or units that are clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.

[0029] According to an embodiment of the present invention, an embodiment of a substation cooling method is provided. It should be noted that the steps shown in the flowchart of the accompanying drawings can be executed in a computer system such as a set of computer executable instructions, and although a logical order is shown in the flowchart, in some cases, the steps shown or described can be executed in an order different from that shown here.

[0030] Figure 1 is a flow chart of a substation cooling method according to an embodiment of the present invention. Figure 1 As shown, the method comprises the following steps:

[0031] Step S102, obtaining multiple current detected temperatures of the substation and multiple current operating states of multiple cooling devices, wherein the cooling devices are used to represent devices for cooling the substation.

[0032] The above-mentioned detected temperature may refer to the real-time temperature reading of the equipment in the substation (such as transformers, switchgear, cable connection points, etc.). The above-mentioned cooling equipment may refer to equipment used to reduce the temperature of the equipment in the substation to ensure that the equipment in the substation operates within a safe temperature range. For example, the above-mentioned cooling equipment may be an air cooler, a water cooler, etc., but is not limited thereto. The above-mentioned operating state may be the working condition of the cooling equipment at a certain moment.

[0033] In an optional embodiment, considering that there may be multiple transformers and different cooling devices in the substation, the temperature and operating status of each cooling device will affect the overall cooling performance of the substation cooling system (hereinafter referred to as the cooling system). In addition, based on real-time temperature data and cooling device status, the cooling system can implement a more efficient and flexible temperature control strategy, thereby improving the cooling effect on the substation. Therefore, the cooling system can obtain multiple current detection temperatures of the substation and multiple current operating states of multiple cooling devices.

[0034] For example, in order to more accurately obtain the current multiple detection temperatures of the substation, the staff can deploy optical temperature sensors near the main body of equipment such as the main transformer in the substation in advance. The optical temperature sensors can use optical sensing technology to detect the temperature of the main transformer body in a non-contact manner, and transmit the detection data to the cooling system in real time. In addition, the staff can also deploy contact temperature sensors on the outer casing of the main transformer of the above-mentioned substation in advance. The contact temperature sensors can measure the temperature of the main transformer body through the contact surface, and transmit the detection data to the cooling system in real time. The cooling system can more comprehensively understand the temperature status of the main transformer by comparing the readings of the above-mentioned non-contact and contact temperature sensors. In order to ensure that the cooling system can effectively respond to the temperature changes of the main transformer, the cooling system can also obtain the current multiple operating states of the above-mentioned multiple cooling devices through wireless communication, so that the cooling system can understand whether the above-mentioned multiple cooling devices are working properly and whether the performance of these cooling devices meets expectations.

[0035] Step S104, based on multiple device identifiers and multiple operating states of multiple cooling devices, obtain at least one target temperature threshold from a temperature threshold table, wherein the temperature threshold table is used to characterize a matching relationship between at least one target temperature threshold and multiple device identifiers and multiple operating states.

[0036] The device identification may be an identification for uniquely identifying each cooling device, for example, the device identification may be a serial number, a location code, etc. of the device, but is not limited thereto. The temperature threshold table is a table for recording the matching relationship between at least one target temperature threshold and multiple device identifications and multiple operating states. The target temperature threshold may be a specific temperature value found from the temperature threshold table according to the device identification and operating state of the current cooling device, and used to guide the device to start, stop or adjust the operating state.

[0037] In an optional embodiment, taking into account that even under the same temperature environment, different cooling devices may have different start and stop temperature thresholds due to different device characteristics, in order to enable the cooling system to more efficiently decide when to start or stop cooling, as well as the degree of cooling according to the specific circumstances of different devices, the cooling system can pre-construct a temperature threshold table, which can be used to characterize the matching relationship between at least one target temperature threshold and multiple device identifiers and multiple operating states. Subsequently, the cooling system can obtain at least one target temperature threshold from the temperature threshold table based on multiple device identifiers and multiple operating states of multiple cooling devices, so as to start the cooling device in time when the temperature rises abnormally, thereby improving the cooling effect on the substation.

[0038] For example, it can be assumed that the cooling system is equipped with two cooling devices: air cooler A, the device identifier can be recorded as A, and water cooler B, the device identifier can be recorded as B, and the cooling system has pre-built the above temperature threshold table. In order to ensure that when the oil temperature of the main transformer in the substation exceeds the safe operating range, the air cooler A and the water cooler B can be sensed and started in time, so as to cool the main transformer to avoid equipment damage or reduced efficiency caused by overheating, the cooling system can obtain the target temperature threshold corresponding to the air cooler A from the above temperature threshold table. For example, the air cooler A is in the "starting" state, the start threshold T1 of the air cooler A is 55°C, and the stop threshold T4 is 45°C. At this time, the target temperature threshold of the air cooler A is the stop threshold T4 of the air cooler A. Similarly, the cooling system can obtain the target temperature threshold corresponding to the water cooler B from the above temperature threshold table. For example, the water cooler B is in the "not running" state, the start threshold T2 of the water cooler B is 60°C, and the stop threshold T3 of the water cooler B is 50°C. At this time, the target temperature threshold of the water cooler B is the start threshold T2 of the water cooler B.

[0039] It should be noted that all the specific values ​​​​such as the number of cooling devices, start threshold T1, start threshold T2, stop threshold T4, stop threshold T3, etc. are only for illustrative purposes. The staff can set them according to actual needs and are not limited here.

[0040] Step S106, matching the multiple detected temperatures with the corresponding target temperature thresholds respectively to obtain multiple temperature matching results.

[0041] The temperature matching result may refer to a result obtained by comparing a temperature value detected in real time by the cooling system with a preset target temperature threshold.

[0042] In an optional embodiment, considering that by matching the detected temperature monitored in real time with a preset temperature threshold, the cooling system can determine in real time whether the current temperature of the substation equipment is within a safe or expected range, thereby improving the response speed of the cooling system to the temperature change of the substation equipment, and further improving the cooling effect on the substation equipment. Therefore, the cooling system can match the above-mentioned multiple detected temperatures with the corresponding target temperature thresholds respectively to obtain multiple temperature matching results. If the above-mentioned temperature matching results show that the detected temperature of the substation equipment exceeds the start threshold, the cooling system can immediately start the corresponding cooling equipment or adjust the operating mode of the cooling equipment to reduce the temperature of the substation equipment, thereby avoiding the reduction of the cooling effect due to the untimely response of the cooling system.

[0043] For example, it can be assumed that the cooling system is equipped with a main air cooler A and a standby air cooler B, which are used to cool the main transformer C of the substation when the temperature is too high. The start temperature threshold T1 of the main air cooler A is 60°C, and the stop temperature threshold T4 is 50°C. The start temperature threshold T2 of the standby air cooler B is 65°C, and the stop temperature threshold T3 is 55°C. The main air cooler A and the standby air cooler B are both in a stopped state at the moment before the current moment. Then, the target temperature threshold at this time is the start temperature threshold T1 of the main air cooler A. In this embodiment, it can be further assumed that the cooling system obtains a real-time oil temperature reading of 64.5°C from the optical temperature sensor deployed on the main transformer C body, and can obtain a real-time oil temperature reading of 63.2°C from the contact temperature sensor deployed on the shell of the main transformer C body. At this time, the cooling system can match the above oil temperature readings with the target temperature thresholds of the main air cooler A and the standby air cooler B to obtain a temperature matching result. The result shows that the oil temperature of the main transformer C is higher than the starting temperature threshold T1 of the main air cooler A, that is, the result can prompt the cooling system to start the main air cooler A to cool the main transformer C.

[0044] It should be noted that all the specific values ​​of the above-mentioned start temperature threshold T1, stop temperature threshold T4, start temperature threshold T2, stop temperature threshold T3, oil temperature reading, etc. are only for illustrative purposes. The staff can adjust them according to actual needs and are not limited here.

[0045] Step S108: controlling the operation of multiple cooling devices based on the multiple temperature matching results to cool the substation.

[0046] In an optional embodiment, considering that there may be multiple cooling devices in the substation and the temperature threshold of each cooling device may be different, based on the above-mentioned multiple temperature matching results, the cooling system can accurately identify which cooling devices need to be started or stopped, thereby controlling the operation of the cooling equipment in a targeted manner, thereby improving the cooling efficiency and energy utilization efficiency of the cooling system for the substation equipment.

[0047] For example, it can be assumed that the main air cooler A and the standby air cooler B included in the cooling system were both in a stopped state at the moment before the current moment. The above multiple temperature matching results indicate that the main air cooler A needs to be started, while the standby air cooler B does not need to be started. At this time, the cooling system can control the main air cooler A to start and run based on the above temperature matching results to cool the main transformer in the substation.

[0048] In an embodiment of the present invention, a plurality of current detection temperatures of a substation and a plurality of current operating states of a plurality of cooling devices are obtained; at least one target temperature threshold is obtained from a temperature threshold table based on a plurality of device identifiers and a plurality of operating states of the plurality of cooling devices; a plurality of detection temperatures are respectively matched with corresponding target temperature thresholds to obtain a plurality of temperature matching results; and the operation of a plurality of cooling devices is controlled based on the plurality of temperature matching results, so that the substation is cooled, the temperature of the substation is obtained, and the abnormal rise in the temperature of the substation is discovered in time, and the target temperature threshold is accurately matched from the temperature threshold table for the current operating state of each cooling device, and the collected detection temperature is compared with the target temperature threshold, so that the cooling system can more accurately determine when to start the cooling device to avoid the problems of over-cooling and insufficient cooling, thereby achieving the purpose of efficiently identifying the temperature changes of the substation and taking corresponding measures in time, thereby achieving the technical effect of quickly responding to and efficiently meeting the cooling needs of the substation, and thus solving the technical problem of poor cooling effect for the substation in the related technology.

[0049] Further, the multiple cooling devices include: a main cooling device and a backup cooling device, the multiple device identifiers include: a first device identifier of the main cooling device and a second device identifier of the backup cooling device, and the multiple operating states include: a first operating state of the main cooling device and a second operating state of the backup cooling device; based on the multiple device identifiers and multiple operating states of the multiple cooling devices, at least one target temperature threshold is obtained from the temperature threshold table, including: based on the first device identifier, the second device identifier and the first operating state, at least one first temperature threshold is selected from the temperature threshold table; based on the second operating state, at least one second temperature threshold is selected from at least one first temperature threshold; in response to receiving a threshold modification instruction, the second temperature threshold is adjusted based on the threshold modification instruction to obtain at least one target temperature threshold; in response to not receiving a threshold modification instruction, at least one second temperature threshold is determined to be at least one target temperature threshold.

[0050] The main cooling device may be the main device for providing cooling services for the substation. The standby cooling device may be a device for assisting the main cooling device to continue to provide cooling services when the main cooling device fails or the cooling effect of the main cooling device cannot meet expectations. The first device identifier may be the device identifier of the main cooling device. The second device identifier may be the identification identifier of the standby cooling device. The first operating state may refer to the operating state of the main cooling device. The second operating state may refer to the operating state of the standby cooling device. The first temperature threshold may be a temperature threshold related to the main cooling device selected from the temperature threshold table based on the device identifier of the main cooling device, the device identifier of the standby cooling device and the current operating state of the main cooling device. The second temperature threshold may be a temperature threshold further adjusted or selected from the first temperature threshold based on the operating state of the standby cooling device, and the second temperature threshold may be used to guide the operation of the standby cooling device. The threshold modification instruction may be an instruction for adjusting the existing temperature threshold according to actual needs.

[0051] In an optional embodiment, considering that a single cooling device may fail or the cooling performance of the device is insufficient to meet the cooling requirements of the substation equipment, the cooling system may include multiple cooling devices, and the multiple cooling devices may be further divided into main cooling devices and backup cooling devices. When the main device fails or requires maintenance, the cooling system can seamlessly switch to the backup cooling device to ensure that the cooling system can maintain a stable cooling effect for the substation equipment. Further considering that the multiple cooling devices (such as air cooling systems and water cooling systems) may have different cooling efficiencies and operating characteristics, by assigning a unique device identifier to each cooling device, the cooling system can accurately identify the cooling device that currently needs to be controlled, thereby achieving more accurate control. Similarly, the cooling system can distinguish the operating status of the main cooling device and the used cooling device. Specifically, the cooling system can divide the operating status of the main cooling device into a first operating status, and can divide the operating status of the backup cooling device into a second operating status. Due to different cooling devices due to their design, installation location, maintenance status and other factors, different temperature thresholds may be required to determine when to start or stop. Therefore, the cooling system can select at least one first temperature threshold from the temperature threshold table based on the first device identifier, the second device identifier and the first operating status. Then, the cooling system can select at least one second temperature threshold from at least one first temperature threshold based on the second operating state, and the cooling system can dynamically adjust the working state of the main cooling device and the backup cooling device according to the above second temperature threshold. If the current second temperature threshold is not enough to meet the cooling demand of the substation equipment, the staff can issue a threshold modification instruction to the cooling system, and the cooling system can adjust the second temperature threshold based on the threshold modification instruction to obtain at least one target temperature threshold. If the current second temperature threshold can meet the cooling demand of the substation equipment, the cooling system can determine at least one second temperature threshold as at least one target temperature threshold.

[0052] For example, it can be assumed that the cooling system includes an air cooler A as a main cooling device and another air cooler B as a standby cooling device. In this embodiment, assuming that the current operating state of air cooler A is to be started, the cooling system can select the start threshold T1 of the main air cooler A as 60°C and the start threshold T2 of the standby air cooler as 65°C from the above temperature threshold table based on the device identification of air cooler A, the device identification of air cooler B and the operating state of air cooler A. Assuming that the current operating state of the standby air cooler is also to be started, the cooling system can select the start threshold T2 of the standby air cooler from the start threshold T1 of the main air cooler A and the start threshold T2 of the standby air cooler as the above second temperature threshold. If the load of the main transformer of the substation is large at this time, and the cooling effect of the current main air cooler A is not enough to meet the cooling demand of the main transformer, the staff can issue a threshold modification instruction to the cooling system. Based on this, the cooling system can adjust the startup threshold T2 of the above-mentioned standby air cooler B, that is, the above-mentioned second temperature threshold to 60°C, so as to start the standby air cooler B earlier, thereby improving the cooling effect on the main transformer. If the current startup temperature thresholds of the main air cooler A and the standby air cooler B can meet the cooling demand of the main transformer, the cooling system can determine the startup temperature threshold T2 of the standby air cooler B as the above-mentioned target threshold.

[0053] It should be noted that the specific values ​​such as the startup threshold value T1 of the main air cooler A and the startup temperature threshold value T2 of the standby air cooler B are only shown as examples. The staff can set them according to actual needs and are not limited here.

[0054] Further, based on the first device identifier, the second device identifier and the first operating state, at least one first temperature threshold is selected from the temperature threshold table, including: in response to the first operating state being that the main cooling device is to be started, selecting a first temperature matching the first operating state from the temperature threshold table based on the first device identifier and the second device identifier, wherein the first temperature is used to characterize the temperature that any detected temperature needs to reach when the main cooling device is started; in response to the first operating state being that the main cooling device is running, selecting a second temperature, a third temperature and a fourth temperature matching the first operating state from the temperature threshold table based on the first device identifier and the second device identifier, wherein the second temperature is used to characterize the temperature that any detected temperature needs to reach when the standby cooling device is started, the third temperature is used to characterize the temperature that any detected temperature needs to reach when the standby cooling device is shut down, and the fourth temperature is used to characterize the temperature that any detected temperature needs to reach when the main cooling device is shut down.

[0055] The first temperature may be the temperature that any one of the detected temperatures needs to reach when the main cooling device is started. The second temperature may be the temperature that any one of the detected temperatures needs to reach when the standby cooling device is started. The third temperature may be the temperature that any one of the detected temperatures needs to reach when the standby cooling device is shut down. The fourth temperature may be the temperature that any one of the detected temperatures needs to reach when the main cooling device is shut down.

[0056] In an optional embodiment, considering that the temperature threshold table stores the temperature threshold information of the main cooling device and the standby cooling device, the temperature threshold information reflects the start-up and shutdown conditions of the main cooling device and the standby cooling device. When the operation state of the main cooling device is to be operated, the cooling system can select the start-up temperature of the main cooling device from the temperature threshold table based on the device identification of the main cooling device and the device identification of the standby cooling device as the first temperature. The cooling system can judge whether it is necessary to start the main cooling device according to whether any of the above detection temperatures reaches the first temperature. If any of the above detection temperatures reaches the first temperature, the cooling system can start the main cooling device to cool the substation equipment. When the operation state of the main cooling device is in operation, the cooling system can select the start-up temperature of the standby cooling device from the temperature threshold table based on the device identification of the main cooling device and the device identification of the standby cooling device as the second temperature, select the stop temperature of the standby cooling device as the third temperature, and select the stop temperature of the main cooling device as the fourth temperature. When the operation state of the standby cooling device is to be operated and any of the detection temperatures reaches the second temperature, the cooling system can start the standby cooling device to improve the cooling effect on the substation equipment. When the operating status of the standby cooling device is running, and any detected temperature reaches the third temperature, it indicates that the temperature of the substation equipment has dropped. At this time, the cooling system can stop the standby cooling device to reduce unnecessary energy loss. When any detected temperature reaches the fourth temperature, it indicates that the temperature of the substation equipment has returned to a safe operating temperature range. At this time, the cooling system can stop the main cooling device. The above steps ensure that the cooling system can efficiently adjust the cooling strategy according to the real-time operating status and equipment characteristics of the cooling equipment, thereby improving the resilience of the cooling system and the cooling effect on the substation equipment.

[0057] Further, selecting at least one second temperature threshold from at least one first temperature threshold based on the second operating state includes: in response to at least one first temperature threshold being a first temperature, determining the first temperature as at least one second temperature threshold; in response to at least one first temperature threshold being a second temperature, a third temperature, and a fourth temperature, determining at least one second temperature threshold from the second temperature, the third temperature, and the fourth temperature based on the second operating state.

[0058] In an optional embodiment, considering that the second temperature threshold can be used as a target temperature threshold to guide the cooling system to adjust the working state of the main cooling device and the standby cooling device without adjusting the temperature threshold, in order to accurately control the start or stop of the main cooling device and the standby cooling device, the cooling system needs to reasonably select the second temperature threshold according to the operating state of the main cooling device and the standby cooling device. Specifically, if the operating state of the main cooling device is to be started, the first temperature threshold obtained by the cooling system from the temperature threshold table should include the start temperature of the main cooling device, that is, the first temperature. At this time, since the cooling system needs to pay attention to when to start the main cooling device without considering the start and stop of the standby cooling device, the cooling system can determine the first temperature as the second temperature threshold. If the operating state of the main cooling device is running, the cooling system obtains the first temperature threshold from the temperature threshold table, which should include the stop temperature of the main cooling device, the start temperature of the standby cooling device, and the stop temperature of the standby cooling device, wherein the stop temperature of the main cooling device is the second temperature, the start temperature of the standby cooling device is the third temperature, and the stop temperature of the standby cooling device is the fourth temperature. At this time, since the cooling system needs to pay attention to when to start the backup cooling device, when to stop the backup cooling device, and when to stop the main cooling device, the cooling system can further determine at least one second temperature threshold from the above-mentioned second temperature, third temperature and fourth temperature based on the operating status of the backup cooling device.

[0059] For example, it can be assumed that the cooling system includes a main air cooler A and a standby air cooler B. When the operating state of the main air cooler A is to be started, the first temperature threshold may at least include the start-up temperature of the main air cooler A. At this time, the cooling system only needs to pay attention to when to start the main air cooler A. Therefore, the start-up temperature of the main air cooler A can be determined as the second temperature threshold. When the operating state of the main air cooler A is running, the first temperature threshold may at least include the stop temperature of the main air cooler A, the start-up temperature of the standby air cooler B, and the stop temperature of the standby air cooler B. At this time, the cooling system needs to further analyze the operating state of the standby air cooler B to determine the second temperature threshold.

[0060] Further, at least one second temperature threshold is determined from the second temperature, the third temperature and the fourth temperature based on the second operating state, including: in response to the second operating state being that the backup cooling device is to be started, determining the second temperature as at least one second temperature threshold; in response to the second operating state being that the backup cooling device is running, determining the third temperature and the fourth temperature as at least one second temperature threshold.

[0061] In an optional embodiment, when the operating state of the main cooling device is running, the cooling system needs to further consider the operating state of the standby cooling device and determine the above-mentioned second temperature threshold, so as to timely adjust the operating states of the main cooling device and the standby cooling device according to the temperature change of the substation equipment, thereby improving the cooling effect on the substation equipment. Specifically, when the operating state of the main cooling device is running, if the operating state of the standby cooling device is to be started, at this time, the cooling system needs to focus on when to stop the main cooling device, so the stop temperature of the main cooling device, that is, the above-mentioned second temperature, can be determined as the above-mentioned second temperature threshold. If the operating state of the standby cooling device is also running, at this time, the cooling system needs to focus on when to stop the standby cooling device and the main cooling device, so the stop temperature of the standby cooling device and the stop temperature of the main cooling device, that is, the above-mentioned third temperature and fourth temperature, can be determined as the above-mentioned second temperature threshold.

[0062] For example, it can be assumed that the cooling system includes a main air cooler A and a standby air cooler B. When the operating state of the main air cooler A is running, if the operating state of the standby air cooler B is waiting to be started, the cooling system needs to pay attention to when to start the standby air cooler B. Therefore, the cooling system can determine the starting temperature of the standby air cooler B as the second temperature threshold. If the operating state of the standby air cooler B is running, the cooling system needs to pay attention to when to stop the standby air cooler B and when to stop the main air cooler A. Therefore, the cooling system can determine the stop temperature of the main air cooler A and the stop temperature of the standby air cooler B as the second temperature threshold.

[0063] Furthermore, obtaining multiple current detection temperatures of the substation includes: obtaining multiple temperature detection devices configured in the substation; performing temperature detection on the substation based on the multiple temperature detection devices to obtain multiple initial temperatures; performing weighted processing on the multiple initial temperatures to obtain weighted temperatures; and obtaining multiple detection temperatures based on the multiple initial temperatures and the weighted temperatures.

[0064] The initial temperature may refer to the temperature value directly measured by each individual temperature detection device in the substation. The weighted temperature may be a temperature calculated by assigning different weights to each temperature value in the multiple initial temperatures.

[0065] In an optional embodiment, considering that the temperature distribution of the substation equipment may be uneven and the temperature at different locations may be different, multiple temperature detection devices configured in the substation can more accurately reflect the working temperature of the substation equipment. The cooling system can detect the temperature of the substation based on multiple temperature detection devices, thereby obtaining the above-mentioned multiple initial temperatures, and providing a data basis for formulating the operation strategy of the cooling equipment. Further considering that different areas or equipment in the substation may have different degrees of influence on the overall temperature of the substation, the cooling system can obtain weighted temperatures by weighting multiple initial temperatures to ensure that the operation strategy of cooling identification focuses more on protecting areas or equipment that have a higher degree of influence on the overall temperature of the substation. After calculating the above-mentioned weighted temperatures, by comprehensively considering multiple initial temperatures and weighted temperatures, the cooling system can more accurately evaluate the thermal conditions of the substation, thereby timely and accurately adjusting the operating status of the main cooling equipment and the standby cooling equipment, thereby improving the cooling effect on the substation.

[0066] For example, in order to more comprehensively obtain the operating temperature of the main transformer of the substation, the staff can deploy a light temperature sensor near the main transformer body of the substation in advance, and deploy a non-contact temperature sensor on the outer shell of the main transformer. The cooling system can obtain the readings of the light temperature sensor and the non-contact temperature sensor in real time as the initial temperature. Since the light temperature sensor detects the temperature of the main transformer body, and the non-contact temperature sensor detects the temperature of the outer shell of the main transformer, the cooling system can assign a higher weight to the temperature detected by the light temperature sensor and a lower weight to the temperature detected by the non-contact temperature sensor. Based on this, the cooling system can perform a weighted calculation on the initial temperature to obtain a weighted temperature, and combine the initial temperature and the weighted temperature to obtain multiple detection temperatures, so that the cooling system can more accurately evaluate the thermal condition of the main transformer and provide a data basis for controlling the start and stop of the cooling equipment.

[0067] Furthermore, the operation of the cooling device is controlled based on multiple temperature matching results, including: in response to the target temperature threshold being a first temperature and the temperature matching result being that any one of the detected temperatures is greater than the first temperature, controlling the main cooling device to operate; in response to the target temperature threshold being a second temperature and the temperature matching result being that any one of the detected temperatures is greater than the second temperature, controlling the standby cooling device to operate; in response to the target temperature threshold being a third temperature and the temperature matching result being that any one of the detected temperatures is less than the third temperature, controlling the standby cooling device to stop operating; in response to the target temperature threshold being a fourth temperature and the temperature matching result being that any one of the detected temperatures is less than the fourth temperature, controlling the main cooling device to stop operating.

[0068] In an optional embodiment, if the operating state of the main cooling device is to be started, the target temperature threshold may be a first temperature. When the temperature matching result shows that any one of the detected temperatures exceeds the first temperature, it indicates that the substation may be at risk of overheating and needs to be cooled. At this time, the cooling system can immediately start the main cooling device to quickly reduce the temperature of the substation to prevent the occurrence of safety accidents. If the operating state of the main cooling device is running and the operating state of the standby cooling device is to be started, the target temperature threshold may be a second temperature. When the temperature matching result shows that any one of the detected temperatures exceeds the second temperature, it indicates that the cooling effect of the main cooling device is insufficient to cope with the current heat load of the substation and requires additional cooling capacity. At this time, the cooling system can start the standby cooling device to ensure that the temperature of the substation will not continue to rise to a dangerous level. If the operating states of the main cooling device and the standby cooling device are both running, the target temperature threshold may be a third temperature. When the temperature matching result shows that any one of the detected temperatures is less than the third temperature, it indicates that the current cooling demand of the substation has been met. The cooling system can shut down the standby cooling device to save energy. If the operating status of the main cooling device is running and the operating status of the standby cooling device is stopped, the above-mentioned target temperature threshold can be a fourth temperature. When the above-mentioned temperature matching result shows that any detected temperature is lower than the fourth temperature, it can be considered that the cooling demand has been met even under low load or ambient temperature. At this time, the cooling system can shut down the main cooling device to avoid overcooling, while ensuring the reliability and safety of the cooling system.

[0069] For example, it can be assumed that the cooling system includes a main air cooler A and a standby air cooler B, and the multiple detected temperatures acquired by the cooling system may include the optical temperature sensor reading T1 of the main transformer and the weighted temperature T2 of the optical temperature sensor, as well as the non-contact temperature sensor reading T3 and the weighted temperature T4 of the non-contact temperature sensor. If the operating state of the main air cooler A is to be started, the above target temperature may be the starting temperature of the main air cooler A. When any value among T1, T2, T3, and T4 is greater than the starting temperature of the main air cooler A, the cooling system may start the main air cooler A to cool the main transformer. If the operating state of the main air cooler A is running and the operating state of the standby air cooler B is to be started, the above target temperature may be the starting temperature of the standby air cooler B. When any value among T1, T2, T3, and T4 is greater than the starting temperature of the standby air cooler B, the cooling system may start the standby air cooler B to assist the main air cooler A in cooling the main transformer. If the operating status of the main air cooler A and the standby air cooler B are both running, the target temperature threshold may be the stop temperature of the standby air cooler B. When any value among T1, T2, T3, and T4 is less than the stop temperature of the standby air cooler B, the cooling system may stop the operation of the standby air cooler B to reduce unnecessary cooling resource overhead. If the operating status of the main air cooler A is running, and the operating status of the standby air cooler B is stopped, the target temperature threshold may be the stop temperature of the main air cooler A. When any value among T1, T2, T3, and T4 is less than the stop temperature of the main air cooler A, the cooling system may stop the operation of the main air cooler A.

[0070] For ease of understanding, Figure 2 is a schematic diagram of an optional cooling device control strategy according to an embodiment of the present invention, such as Figure 2 As shown: the horizontal axis represents time, the vertical axis represents temperature, T1 represents the start-up temperature of the main air cooler, T2 represents the start-up temperature of the standby air cooler, T3 represents the stop temperature of the standby air cooler, and T4 represents the stop temperature of the main air cooler, wherein T2>T3>T1>T4, when the detection temperature of the main transformer of the substation reaches T1 for the first time, the cooling system can start the main air cooler to cool the main transformer. When the detection temperature of the main transformer further increases and reaches T2, the cooling system can start the standby air cooler to enhance the cooling capacity to cope with more serious overheating risks. When the detection temperature of the main transformer begins to drop and is lower than T3, the cooling system can stop the operation of the standby air cooler. When the detection temperature of the main transformer further drops below T4, the cooling system can stop the operation of the main air cooler to avoid unnecessary energy consumption when the temperature of the main transformer returns to normal.

[0071] Furthermore, the method also includes: obtaining historical temperature data of the substation in a historical time period; constructing a temperature alarm threshold based on the historical temperature data; in response to any one of the multiple detected temperatures being greater than the temperature alarm threshold, outputting an alarm prompt message, wherein the alarm prompt message is used to prompt the user that there is a safety risk in the substation.

[0072] The above historical temperature data may refer to the temperature data of the substation before the current moment. The above temperature alarm threshold may be a temperature value set by the cooling system after analyzing the historical temperature data, and the temperature value may be used to determine whether there is a safety risk in the substation. The above alarm prompt information may be information used to notify staff that there is a safety risk in the substation.

[0073] In an optional embodiment, considering that the above historical temperature data can reflect the temperature fluctuation pattern of the substation under different operating conditions, ambient temperatures and loads, it helps the cooling system predict the potential overheating risk of the substation. Therefore, the cooling system can obtain the historical temperature data of the substation in the historical time period to identify the normal operating temperature range and abnormal temperature rise of the substation. Then, the cooling system can construct the above temperature alarm threshold by analyzing the statistical characteristics of the historical temperature data, such as average temperature, temperature fluctuation range, seasonal factors, etc. Once any of the above multiple detection temperatures is greater than the temperature alarm threshold, the cooling system can output an alarm prompt message to the staff to inform the staff that there is a safety risk in the substation, so that the staff can take timely measures to avoid the occurrence of safety accidents.

[0074] For example, the cooling system can obtain the temperature data of the main transformer of the substation in the past year, especially the data during the summer peak period, as the basis for building the temperature alarm threshold. The cooling system can analyze the above data and find out that during the summer peak period, the temperature fluctuation range of the main transformer of the substation is 60℃ to 95℃, with an average temperature of 80℃. Based on this, the cooling system can set the above temperature alarm threshold to 90℃. When any of the multiple detection temperatures is greater than 90℃, the cooling system can send alarm information to the staff through mobile phone text messages and pop-up windows on the monitoring interface, so that the staff can perceive and handle the abnormal situation of the main transformer in time.

[0075] It should be noted that the specific values ​​such as the temperature fluctuation range, average temperature, temperature alarm threshold of the above-mentioned main transformer are only shown for example. The staff can set them according to actual needs and are not limited here.

[0076] For ease of understanding, Figure 3 is a structural diagram of an optional temperature control system for a main transformer of a substation according to an embodiment of the present invention, such as Figure 3As shown, the structure includes: a light temperature sensor 302, which is used to detect the temperature of the main transformer body in a non-contact manner through light sensing technology. The temperature data detected by the light temperature sensor will be transmitted to the microcomputer control device 310 in real time for processing. A contact temperature sensor 304 is directly installed on the main transformer body shell. The contact temperature sensor measures the temperature by contact and transmits the measured temperature data to the microcomputer control device 310 for processing. A power supply device 306 is used to provide power support for the entire system. A human-computer interaction module 308 is used for the staff to manually start or stop the air cooler and set various operating parameters, such as temperature threshold and air cooler switching time. The microcomputer control device 310 is used to receive temperature data from the light temperature sensor 302 and the contact temperature sensor 304, and control the operation of the air cooler according to a preset air cooling control strategy. In addition, the microcomputer control device 310 is also connected to the power supply device 306 and the human-computer interaction module 308 to realize monitoring and control of the entire system. The air cooler 312 and the air cooler 314 are used to cool the main transformer, and the start and stop of the air cooler 312 and the air cooler 314 are controlled by the microcomputer control device 310. The air cooler current sensor 316 and the air cooler current sensor 318 are connected to the air cooler 312 and the air cooler 314, respectively, and are used to monitor the operating current of the air cooler 312 and the air cooler 314, so as to determine whether the air cooler 312 and the air cooler 314 are operating normally.

[0077] Figure 4 is a detailed flow chart of an optional substation transformer temperature control method according to an embodiment of the present invention, such as Figure 4As shown, when the process starts, the cooling system can first detect whether the staff has performed a manual start operation. If the cooling system does not detect a manual start signal, it will detect the temperature of the main transformer and determine whether the detected temperature is greater than or equal to the start-up setting of the air cooler. If the detected temperature is greater than or equal to the start-up setting of the air cooler, or in the above steps, the cooling system detects a manual start signal, the cooling system can start the air cooler operation status detection, and then the cooling system can further monitor whether the air cooler current is greater than or equal to the air cooler current setting. If the air cooler current is greater than or equal to the air cooler current setting, it can be considered that the air cooler is normal and the result is displayed to the staff. If the air cooler current is less than the air cooler current setting, it can be considered that the air cooler is faulty, and the result is also displayed to the staff. If in the above steps, the detected temperature is less than the start-up setting of the air cooler, the cooling system can start the temperature sensor operation status detection, and further determine whether the measured temperature difference of the temperature sensor is less than or equal to the temperature setting. If the measured temperature difference of the temperature sensor is less than or equal to the temperature setting, the cooling system can determine that the temperature sensor is normal and display the result to the staff. If the temperature difference measured by the temperature sensor is greater than the temperature setting value, the cooling system can determine that the temperature sensor is abnormal and display the result to the staff, and the whole process ends here.
