Description

Technical Field

[0001] The present invention relates to the technical field of environmental monitoring of substations, and in particular to a method, device, electronic equipment and storage medium for environmental monitoring of substations. Background Art

[0002] Substations, as hubs in the power system, house a vast array of equipment. These include those that directly generate, transmit, distribute, and use electrical energy, such as transformers, high-voltage circuit breakers, lightning arresters, and capacitors, as well as equipment that measures, monitors, controls, and protects these devices, including relay protection devices, automatic devices, measurement and control equipment, metering devices, and automation systems. Due to the large number of devices housed within substation rooms, the heat generated by these devices during operation raises the room's temperature, further impacting the normal operation of these devices.

[0003] Conventional technology typically monitors and automatically controls the substation room environment by deploying temperature and humidity sensors within the substation room. These sensors monitor the room's temperature and humidity, allowing the air conditioning system to adjust the temperature and humidity. However, this single-source approach of monitoring the substation's environmental status through temperature and humidity sensors fails to accurately reflect the substation's actual environment, potentially impacting automatic control. Summary of the Invention

[0004] The present invention provides a method, device, electronic equipment and storage medium for monitoring the environment of a substation, so as to improve the accuracy of substation environmental monitoring and enhance the effectiveness and timeliness of substation environmental control measures.

[0005] In a first aspect, an embodiment of the present invention provides a method for monitoring an environment in a substation, the method comprising:

[0006] Determine the temperature of the substation area based on the thermal imaging image of the substation area, and determine the temperature change trend based on the temperature of the substation area;

[0007] If it is determined that the temperature change trend satisfies the first trend change condition, determining the temperature and / or humidity of the substation area, and the outside temperature and / or humidity;

[0008] Determining environmental control measures for the first substation based on the temperature and / or humidity of the substation area and the outside temperature and / or humidity, and determining a trend of change in the outside temperature and / or humidity;

[0009] If it is determined that the change trend of the external temperature and / or humidity meets the second trend change condition, the second substation environment control measure is determined.

[0010] In a second aspect, an embodiment of the present invention further provides an environmental monitoring device for a substation, the device comprising:

[0011] A temperature change trend determination module is used to determine the temperature of the substation area based on the thermal imaging image of the substation area, and determine the temperature change trend based on the temperature of the substation area;

[0012] a temperature and humidity determination module, configured to determine the temperature and / or humidity of the substation area, and the outside temperature and / or humidity, if it is determined that the temperature change trend satisfies a first trend change condition;

[0013] A first substation environmental control measure determination module, configured to determine the first substation environmental control measure based on the temperature and / or humidity of the substation area and the external temperature and / or humidity, and to determine a change trend of the external temperature and / or humidity;

[0014] The second substation environment control measure determination module is configured to determine the second substation environment control measure if it is determined that the change trend of the external temperature and / or humidity meets the second trend change condition.

[0015] In a third aspect, an embodiment of the present invention further provides an electronic device comprising a memory, a processor, and a computer program stored in the memory and executable on the processor, wherein when the processor executes the program, an environmental monitoring method for a substation as described in any one of the embodiments of the present invention is implemented.

[0016] In a fourth aspect, an embodiment of the present invention further provides a storage medium storing computer-executable instructions, which, when executed by a computer processor, are used to execute the environmental monitoring method for a substation as described in any one of the embodiments of the present invention.

[0017] The technical solution of the embodiment of the present invention monitors the temperature of the substation area through thermal imaging images and determines the temperature change trend. When the temperature change trend meets the first trend change condition, the temperature and / or humidity of the substation area and the external temperature and / or humidity are compared to determine the corresponding first substation environmental control measures. At the same time, the trend of change of the external temperature and / or humidity is monitored. When the trend of change of the external temperature and / or humidity meets the second trend change condition, the second substation environmental control measures are determined. This solves the problem of poor accuracy of the existing method of environmental monitoring based solely on temperature and humidity within the substation, improves the accuracy of substation environmental monitoring, and improves the effectiveness and timeliness of substation environmental control measures.

[0027] Example 1

[0028] Figure 1 A flowchart of a method for environmental monitoring of a substation is provided for the first embodiment of the present invention. This embodiment is applicable to the situation where environmental monitoring of a substation machine room is performed. The method can be performed by an environmental monitoring device of the substation. The environmental monitoring device of the substation can be implemented in the form of hardware and / or software. The environmental monitoring device of the substation can be configured in a server or electronic device.

[0029] like Figure 1 As shown, the method includes:

[0030] S110 : Determine the temperature of the substation area according to the thermal imaging image of the substation area, and determine a temperature change trend based on the temperature of the substation area.

[0031] Thermal imaging uses thermal imaging technology to detect thermal radiation (heat) in the transformer area and convert it into a visual image. Thermal imaging cameras, thermal imagers, and other equipment can be installed in the substation area to capture thermal images in real time. Furthermore, the substation area can be divided into multiple sub-areas, with thermal images collected for each sub-area and subsequent steps performed separately. This allows for zoned environmental monitoring of the substation area and improves the accuracy of environmental monitoring within the substation area.

[0032] To determine the substation area's temperature based on thermal images of the area, the temperature of each pixel in the thermal image can be calculated using the pixel grayscale values in the thermal image and a pre-calibrated temperature calculation model. The substation area temperature can be represented by the average or maximum temperature of each pixel in the thermal image.

[0033] The temperature trend is the temporal trend of the substation area temperature, which can be represented by a substation area temperature trend curve. A temperature trend curve can be drawn based on the temperature of each substation area within a preset time period before the current moment.

[0034] In this embodiment, thermal imaging images are collected in real time, and the temperature of the substation area is determined based on the thermal imaging images. This can be performed in real time or periodically, for example, temperature determination and temperature change trend monitoring are performed every 10 minutes. This embodiment does not limit this.

[0035] S120: If it is determined that the temperature change trend meets the first trend change condition, determine the temperature and / or humidity of the substation area, and the external temperature and / or humidity.

[0036] The first change trend condition refers to the temperature change in the substation area progressing in an unfavorable direction. Specifically, it can be summarized as the temperature in the substation area is high and has a rising trend.

[0037] In this embodiment, when the temperature variation in the substation area develops in an unfavorable direction, it indicates that the temperature in the substation area is elevated, and certain treatment measures are required to reduce the temperature in the substation area. However, this temperature variation in the substation area could be caused by a rise in the external ambient temperature, or it could be caused by heating of equipment in the substation area under normal external conditions. Therefore, it is necessary to further consider the external environment to determine the appropriate cooling measures for the substation area.

[0038] In an optional embodiment, determining that the temperature change trend meets the first trend change condition can be that it lasts for a preset time, or the substation area temperature corresponding to more than a preset number of sampling time points is greater than or equal to a preset temperature threshold.

[0039] In another optional embodiment, determining that the temperature change trend meets the first trend change condition may also be that the temperature change trend of the substation area temperature within a preset time period, or corresponding to more than a preset number of sampling time points is an increasing trend, and the temperature average value is greater than or equal to a preset temperature threshold.

[0040] In another optional embodiment, determining that the temperature change trend satisfies the first trend change condition may further include: determining the slope of the temperature change trend curve; if it is determined that the slope is greater than or equal to the duration of a preset slope threshold, and greater than or equal to a preset time threshold, then determining that the temperature change trend satisfies the first trend change condition.

[0041] Specifically, if the slope of the temperature change trend curve is greater than or equal to the duration of the preset slope threshold, and greater than or equal to the preset first time threshold, that is, the slope of the temperature change trend curve is large for a period of time, it indicates that there is a continuous sudden increase in temperature. At this time, it is determined that the temperature change in the substation area is developing in an unfavorable direction.

[0042] The temperature of the substation area can be determined directly from thermal imaging or measured using temperature sensors deployed within the substation area. The humidity of the substation area can be measured using humidity sensors deployed within the substation area. The outside temperature can be measured using temperature sensors deployed in areas outside the substation area. The outside humidity can be measured using humidity sensors deployed in areas outside the substation area.

[0043] Furthermore, when performing zoned environmental monitoring on the substation area, the external area can also be divided, and the external temperature and / or humidity of each external sub-area can be monitored separately, thereby improving the accuracy of automatic temperature control of the substation.

[0044] In this embodiment, when the temperature in the substation area develops in an unfavorable direction, by monitoring the external temperature and humidity environment and comparing the external temperature and humidity environment with the temperature and humidity environment in the substation area, the impact of the external temperature and humidity environment on the temperature change in the substation area can be accurately determined, thereby improving the accuracy of automatic control of the temperature in the substation area.

[0045] S130: Determine first substation environmental control measures based on the temperature and / or humidity of the substation area and the external temperature and / or humidity, and determine a change trend of the external temperature and / or humidity.

[0046] The first substation environmental control measure may be one or more of a series of measures to reduce the temperature in the substation area. For example, the first substation environmental control measure may include turning on the ventilation system, turning on the air conditioning system, and issuing an alarm indicating that the substation area temperature is too high.

[0047] The first substation environmental control measure is determined based on the temperature and / or humidity of the substation area and the external temperature and / or humidity. The advantages and disadvantages of the substation area environment and the external environment can be determined based on the temperature and / or humidity of the substation area and the external temperature and / or humidity.

[0048] If the external environment is better than the substation area, the substation area temperature will develop in an unfavorable direction. The main reason is the heat generated by the equipment during operation in the substation area. In this case, because the external environment is better than the substation area, the fan system can be turned on to ventilate the substation area, achieving the effect of cooling the substation area while ensuring economic efficiency.

[0049] If the external environment is worse than the substation's, the substation's temperature will deteriorate. This can be due to heat generated by equipment operating within the substation or the effects of the external environment. Furthermore, since the external environment is worse than the substation's, simple ventilation is insufficient to cool the substation area. Air conditioning systems must be activated to cool the substation area.

[0050] This embodiment monitors the external temperature and humidity environment and compares the external temperature and humidity environment with the temperature and humidity environment of the substation area. When performing substation area environmental monitoring and automatic control, it can take into account the impact of the external environment on the substation area environment and take different substation environmental control measures in a targeted manner. While ensuring economy, it can achieve an effective cooling effect in the substation area, thereby realizing accurate automatic control of the substation area temperature.

[0051] Similar to the temperature variation trend of the substation area temperature, the variation trend of the outside temperature and / or humidity can be represented by an outside temperature and / or outside humidity variation trend curve. The outside temperature variation trend curve can be drawn based on the outside temperatures collected during a preset time period, and the outside humidity variation trend curve can be drawn based on the outside humidity collected during a preset time period.

[0052] In this embodiment, after taking the preliminary first substation environmental control measures for the substation area, in order to ensure the effectiveness of the environmental control measures and achieve effective cooling of the substation area, it is also necessary to continuously monitor the changing trends of the external temperature and / or humidity.

[0053] S140: If it is determined that the change trend of the external temperature and / or humidity meets the second trend change condition, determine the second substation environment control measures.

[0054] The second trend change condition refers to the external environment changing in an unfavorable direction. Specifically, if the change trend of the external temperature and / or humidity meets the second trend change condition, it means that the external environment is becoming increasingly severe.

[0055] In an optional embodiment, determining that the changing trend of the outside temperature and / or humidity satisfies the second trend change condition may be that the outside temperature corresponding to a preset time period, or for more than a preset number of sampling time points, is greater than or equal to a preset temperature threshold. And / or, the outside humidity corresponding to a preset time period, or for more than a preset number of sampling time points, is greater than or equal to a preset humidity threshold.

[0056] In another optional embodiment, determining whether the changing trend of the outside temperature and / or humidity satisfies the second trend change condition may also be based on the outside temperature showing an increasing trend within a preset time period or for more than a preset number of sampling time points, and the average temperature being greater than or equal to a preset temperature threshold. Furthermore, / or, the outside humidity showing an increasing trend within a preset time period or for more than a preset number of sampling time points, and the average humidity being less than or equal to a preset humidity threshold.

[0057] In yet another optional embodiment, determining that the changing trend of the outside temperature and / or humidity satisfies the second trend change condition may also include determining an external environment evaluation value based on the outside temperature and / or humidity, where the external environment evaluation value is inversely proportional to the outside temperature and the outside humidity. If the duration for which the external environment evaluation value is less than or equal to a preset evaluation value threshold is greater than or equal to a preset time threshold, then the changing trend of the outside temperature and / or humidity is determined to satisfy the second trend change condition.

[0058] In this embodiment, when the changing trend of the external temperature and / or humidity meets the second trend change condition, it indicates that the external environmental conditions are developing in a deteriorating direction. On the basis of having taken the first substation environmental control measures, it is necessary to further take the second substation environmental control measures.

[0059] Furthermore, since different first substation environmental control measures are implemented when the external environment is better than the substation area environment and when the external environment is worse than the substation area environment, correspondingly, different second substation environmental control measures are required when the external environment conditions deteriorate.

[0060] When the external environment is better than the substation area environment, the first substation environmental control measure may be to control the fan system to be turned on, etc. Correspondingly, the second substation environmental control measure may be to increase the wind speed of the fan system, control the fan system to be turned off and control the air conditioning system to be turned on at the same time.

[0061] When the external environment is worse than the substation area environment, the first substation environmental control measure may be to control the air-conditioning system to turn on, etc. Correspondingly, the second substation environmental control measure may be to lower the set temperature and wind speed of the air-conditioning system, and to issue an alarm prompt for the deterioration of the external environment.

[0062] In this embodiment, when the temperature change trend meets the first trend change condition, different first substation environmental control measures are implemented based on the difference between the external environment and the substation area environment. Simultaneously, the external environment change trend is monitored, and when the external temperature and / or humidity change trend meets the second trend change condition, different second substation environmental control measures are implemented. By comparing the external environment with the substation environment and monitoring the external environment change trend, this embodiment fully considers the impact of the external environment on the temperature within the substation area, thereby improving the precision and accuracy of automatic temperature control within the substation area.

[0063] The technical solution of the embodiment of the present invention monitors the temperature of the substation area through thermal imaging images and determines the temperature change trend. When the temperature change trend meets the first trend change condition, the temperature and / or humidity of the substation area and the external temperature and / or humidity are compared to determine the corresponding first substation environmental control measures. At the same time, the trend of change of the external temperature and / or humidity is monitored. When the trend of change of the external temperature and / or humidity meets the second trend change condition, the second substation environmental control measures are determined. This solves the problem of poor accuracy of the existing method of environmental monitoring based solely on temperature and humidity within the substation, improves the accuracy of substation environmental monitoring, and improves the effectiveness and timeliness of substation environmental control measures.

[0064] Example 2

[0065] Figure 2 This is a flow chart of a substation environment monitoring method provided by the second embodiment of the present invention. Based on the above embodiments, this embodiment of the present invention further specifies the process of determining the first substation environment control measures and the second substation environment control measures.

[0066] like Figure 2 As shown, the method includes:

[0067] S210 : Determine the temperature of the substation area according to the thermal imaging image of the substation area, and determine a temperature change trend based on the temperature of the substation area.

[0068] S220 , determining whether the temperature change trend satisfies the first trend change condition; if so, executing S230 ; otherwise, returning to executing S210 .

[0069] S230: Determine the temperature and / or humidity of the substation area, and the outside temperature and / or humidity.

[0070] The above embodiments have specifically described the process of determining the temperature of the substation area based on thermal imaging images and determining the temperature change trend, the process of judging whether the temperature change trend meets the first trend change condition, and the temperature and humidity monitoring process of the substation area and the outside world. This embodiment will not be repeated here.

[0071] S240: Determine a substation environment evaluation value based on the temperature and / or humidity of the substation area, and determine an external environment evaluation value based on the external temperature and / or humidity.

[0072] In this embodiment, the temperature and / or humidity are quantified as environmental evaluation values, thereby achieving a comparison between the environmental quality of the substation area and the external area.

[0073] Specifically, temperature and humidity are inversely proportional to the substation environmental evaluation value. That is, the higher the temperature and humidity, the worse the environmental conditions. Especially for the environment within the substation area, the higher the temperature and humidity, the greater the impact on the operating status of the equipment in the substation area.

[0074] Therefore, when performing environmental evaluation based solely on temperature or humidity, the temperature or humidity value can be directly used as the substation environmental evaluation value. When determining the environmental evaluation value based on a combination of temperature and humidity, in this embodiment, the temperature and humidity can be normalized separately, and then the normalized values can be weighted and summed according to the weights of temperature and humidity to obtain the final environmental evaluation value.

[0075] S250. Determine whether the substation environment evaluation value is less than or equal to the external environment evaluation value. If so, execute S260; otherwise, execute S270.

[0076] In this embodiment, the smaller the environmental evaluation value, the higher the temperature and humidity level, and the worse the environment. Therefore, when the substation environmental evaluation value is less than or equal to the external environmental evaluation value, the external environmental conditions are better than the environmental conditions inside the substation area.

[0077] S260: If no security alarm information is received within a preset time period before the current moment, the fan system is controlled to cool the substation area.

[0078] Controlling the fan system includes controlling at least one of the mode, gear and wind speed of the fan system.

[0079] When external environmental conditions are better than those within the substation area, ventilation can be used to cool the substation area. This embodiment further incorporates a security alarm information determination process. As can be understood, since the substation area is a key machine room location, safety must be ensured before ventilation is implemented. Therefore, if no security alarm information is received within a preset time period prior to the current moment, it indicates that the substation area is secure and the fan system can be activated for ventilation and cooling.

[0080] Furthermore, the fan system control process can be further refined based on the substation environmental evaluation value. For example, fan system control can include: turning on the fan system, adjusting the fan system mode to a non-hot air mode; adjusting the fan system to different gears or wind speeds based on the substation environmental evaluation value; and if the fan system is already on, increasing the gear or wind speed.

[0081] S270. Control the air conditioning system to cool the substation area.

[0082] Controlling the air-conditioning system includes controlling at least one of the mode, temperature, humidity and wind speed of the air-conditioning system.

[0083] When the substation environmental evaluation value is greater than the external environmental evaluation value, the external environmental conditions are worse than those inside the substation area. Turning on the fan system may further increase the temperature within the substation area. Therefore, the air conditioning system needs to be controlled to cool the substation area.

[0084] Similarly, the air conditioning system's control process can be further refined based on the substation environmental evaluation value. For example, controlling the air conditioning system could include: turning it on; changing the air conditioning system mode to automatic or cooling; adjusting the air conditioning system's temperature, humidity, and wind speed based on the substation environmental evaluation value; and, if the air conditioning system is already on, lowering the temperature, increasing the dehumidification level, and increasing the wind speed.

[0085] S280: Determine a change trend of the external temperature and / or humidity.

[0086] S290. Determine whether the change trend of the external temperature and / or humidity meets the second trend change condition. If so, execute S2100; otherwise, return to execute S210.

[0087] This embodiment takes drawing an external temperature change trend curve and an external humidity change trend curve as an example to illustrate the judgment process of the second trend change condition.

[0088] Furthermore, S290 can include:

[0089] S291. Determine the slope of the external temperature change trend curve and / or the slope of the humidity change trend curve, and determine an external environment change trend evaluation value based on the slope of the external temperature change trend curve and / or the slope of the humidity change trend curve;

[0090] S292: If it is determined that the duration of the external environment change trend evaluation value is greater than or equal to the preset evaluation value threshold, and is greater than or equal to the preset time threshold, it is determined that the change trend of the external temperature and / or humidity meets the second trend change condition.

[0091] When evaluating the external environment change trend based solely on the slope of the external temperature change trend curve or the slope of the external humidity change trend curve, the slope of the external temperature change trend curve or the slope of the external humidity change trend curve can be directly used as the external environment change trend evaluation value. When combining the slopes of the external temperature change trend curve and the slope of the external humidity change trend curve, the slopes of the external temperature change trend curve and the slopes of the external humidity change trend curve corresponding to the same time point can be weighted and summed according to the weights of the external temperature and the external humidity to obtain the external environment change trend evaluation value.

[0092] Similar to the judgment process of temperature change trend, if the external environment change trend evaluation value is greater than or equal to the duration of the preset evaluation value threshold, and is greater than or equal to the preset time threshold, it is considered that the external environment change is tending to be severe and meets the second trend change condition.

[0093] S2100. Determine environmental control measures for the second substation.

[0094] When the external environment becomes worse, it is necessary to adopt different second substation environmental control measures based on the first substation environmental control measures and according to the advantages and disadvantages of the substation environment and the external environment.

[0095] Specifically, if it is determined that the substation environment evaluation value is less than or equal to the external environment evaluation value, then S2100 includes: issuing an alarm prompt for changes in the external environment trend, and controlling the air-conditioning system to cool the substation area; if it is determined that the substation environment evaluation value is greater than the external environment evaluation value, then S2100 includes: issuing an alarm prompt to stay away from the dangerous area.

[0096] In this embodiment, if the substation environment deteriorates compared to the external environment, the first substation environmental control measure is to control the fan system to cool the substation area. If the external environment deteriorates, the second substation environmental control measure is to issue an environmental trend change alarm and control the air conditioning system to cool the substation area. Similarly, controlling the air conditioning system may include controlling at least one of the system's mode, temperature, humidity, and wind speed.

[0097] If the substation environment is better than the external environment, the first substation environmental control measure is to control the air conditioning system to cool the substation area. If the external environment deteriorates, the second substation environmental control measure is to issue a warning to stay away from the dangerous area. Specifically, this can be done through voice prompts or other means such as broadcasting within the substation area.

[0098] The technical solution of this embodiment is to take different first substation environmental control measures according to the advantages and disadvantages of the external environment and the substation area environment when the temperature change trend meets the first trend change condition. At the same time, the external environment change trend is monitored, and when the change trend of the external temperature and / or humidity meets the second trend change condition, different second substation environmental control measures are taken on the basis of the first substation environmental control measures. This embodiment fully considers the impact of the external environment on the temperature in the substation area by introducing the comparison between the external environment and the substation environment, and monitoring the change trend of the external environment, thereby improving the precision and accuracy of automatic temperature control in the substation area. At the same time, different degrees of environmental control measures are taken for different situations, thereby improving economic efficiency.

[0099] Example 3

[0100] Figure 3 This is a schematic diagram of the structure of an environmental monitoring device for a substation provided by the third embodiment of the present invention. Figure 3 As shown, the device includes:

[0105] The technical solution of the embodiment of the present invention monitors the temperature of the substation area through thermal imaging images and determines the temperature change trend. When the temperature change trend meets the first trend change condition, the temperature and / or humidity of the substation area and the external temperature and / or humidity are compared to determine the corresponding first substation environmental control measures. At the same time, the trend of change of the external temperature and / or humidity is monitored. When the trend of change of the external temperature and / or humidity meets the second trend change condition, the second substation environmental control measures are determined. This solves the problem of poor accuracy of the existing method of environmental monitoring based solely on temperature and humidity within the substation, improves the accuracy of substation environmental monitoring, and improves the effectiveness and timeliness of substation environmental control measures.
