To address this issue, relevant technologies typically employ a humidity threshold triggering method to activate dehumidifiers. This means that when the humidity exceeds a set value, the dehumidifier is directly controlled to dehumidify at a fixed power level. However, the current surge and electromagnetic interference generated during the activation of the dehumidifier can affect the normal operation of the power distribution equipment, thus adversely impacting its stable operation.

Detailed Implementation

[0021] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application. Unless otherwise specified, the embodiments and features in the embodiments of this application can be arbitrarily combined with each other. Furthermore, although a logical order is shown in the flowchart, in some cases, the steps shown or described may be performed in a different order than that shown here.

[0022] The terms "first" and "second" in the specification, claims, and accompanying drawings of this application are used to distinguish different objects, not to describe a specific order. Furthermore, the term "comprising" and any variations thereof are intended to cover non-exclusive protection. For example, a process, method, system, product, or device that includes a series of steps or units is not limited to the listed steps or units, but may optionally include steps or units not listed, or may optionally include other steps or units inherent to these processes, methods, products, or devices. The term "multiple" in this application can mean at least two, for example, two, three, or more, and the embodiments of this application do not impose limitations.

[0023] This application provides a method, apparatus, equipment, medium, and program product for dehumidifying power distribution equipment. By determining dehumidification information in advance, the operation of the dehumidification equipment is controlled based on the dehumidification information after the power distribution equipment is shut down, thereby solving the problem in related technologies where the start-up of the dehumidification equipment affects the normal operation of the power distribution equipment.

[0024] The dehumidification method for power distribution equipment according to embodiments of this application will be described in detail below.

[0025] See Figure 1 , Figure 1 This is a flowchart of a dehumidification method for power distribution equipment provided in this application, such as... Figure 1 As shown, the method includes: Step 101: Under the condition that the dehumidification conditions are met, obtain the first actual humidity, the target humidity, and the downtime of the next shutdown of the power distribution equipment. The target humidity is less than the first actual humidity.

[0026] The aforementioned first actual humidity refers to the measured humidity of the power distribution equipment. As an example, the actual humidity of the power distribution equipment can be collected using an anti-condensation device. Specifically, the anti-condensation device includes a condensation sensor, which can be used to collect the aforementioned actual humidity.

[0027] In some embodiments, the actual humidity may be the most recently collected actual humidity after it has been determined that the dehumidification conditions are met.

[0028] In other embodiments, to improve the accuracy of the actual humidity, the first actual humidity can be the average actual humidity of the power distribution equipment within a second preset time period before the target sampling time.

[0029] The target sampling time is before the next shutdown. For example, after confirming that the dehumidification conditions are met, the sampling time corresponding to the most recent actual humidity reading can be directly used as the target sampling time. Alternatively, the start time of the next shutdown can be obtained, and if the time interval between the current sampling time and the start time of the shutdown is less than a preset time interval, the current sampling time can be used as the target sampling time.

[0030] The target humidity is a preset value. For example, the target humidity can be an initial preset value; or, for example, a prompt message can be sent to the terminal when the dehumidification conditions are met, prompting the staff to input the target humidity.

[0031] Step 102: Determine dehumidification information based on the deviation between the actual humidity and the target humidity, as well as the downtime. The dehumidification information includes dehumidification power and dehumidification duration, where the dehumidification duration is less than or equal to the downtime.

[0032] The target humidity is the goal of dehumidification. After dehumidifying according to the above dehumidification information, the actual humidity of the power distribution equipment can be equal to or close to the target humidity.

[0033] Step 103: When the power distribution equipment is shut down, control the dehumidification equipment to start running based on the dehumidification information.

[0034] The aforementioned dehumidification equipment can be a semiconductor dehumidifier. Specifically, the aforementioned decondensation device may include the aforementioned condensation sensor and semiconductor dehumidifier.

[0035] The condensation sensor operates continuously to monitor humidity data within the power distribution equipment in real time. In the event of a power distribution equipment shutdown (e.g., upon receiving a shutdown signal), the control semiconductor dehumidifier starts operating based on this dehumidification information.

[0036] In this embodiment, dehumidification information is calculated in advance. When the power distribution equipment is shut down, the dehumidification equipment is then controlled to start operating based on this information, and the dehumidification duration is less than or equal to the shutdown duration. This avoids the dehumidification equipment's startup affecting the operation of the power distribution equipment, thus improving the operational stability of the power distribution equipment.

[0037] The above dehumidification information is used to control the actual humidity of the power distribution equipment to be equal to or close to the target humidity. Specifically: It can calculate the deviation between the actual humidity and the target humidity, and determine the target dehumidification energy consumption based on the deviation. For example, based on the preset mapping relationship between deviation and dehumidification energy consumption, the target dehumidification energy consumption corresponding to the above deviation can be determined.

[0038] Based on the target dehumidification energy consumption, the dehumidification power and dehumidification duration can be determined. The dehumidification duration can be determined directly by the downtime, or by the difference between the downtime and the reserved time. The reserved time is, for example, 2 seconds or 3 seconds.

[0039] In some embodiments, the dehumidification power can be determined as a fixed dehumidification power, and the product of the fixed dehumidification power and the dehumidification time is the actual dehumidification energy consumption. The absolute value of the deviation between the target dehumidification energy consumption and the actual dehumidification energy consumption is less than or equal to a first preset threshold (the first preset threshold is greater than or equal to 0). In this way, the actual humidity of the power distribution equipment can be controlled to approach the target humidity.

[0040] In other embodiments, the dehumidification power can be determined as a power that varies with time, that is, the dehumidification power corresponding to each dehumidification moment can be determined. The integral of the dehumidification power and the corresponding dehumidification moment is the actual dehumidification energy consumption, and the absolute value of the deviation between the target dehumidification energy consumption and the actual dehumidification energy consumption is less than or equal to a first preset threshold.

[0041] In this embodiment, by determining the dehumidification power corresponding to each dehumidification moment, it is beneficial to more accurately control the deviation between the target dehumidification energy consumption and the actual dehumidification energy consumption, thereby helping to further control the actual humidity to approach the target humidity.

[0042] In some embodiments, the dehumidification power corresponding to each dehumidification moment within the dehumidification duration is determined based on dehumidification energy consumption and dehumidification duration, including: Determine the initial dehumidification power corresponding to the initial dehumidification time. The initial dehumidification power is a preset value that is greater than 0 and less than the rated power. Starting with the initial dehumidification power, the dehumidification power corresponding to each dehumidification moment within the dehumidification time is determined based on the dehumidification energy consumption and dehumidification duration.

[0043] In this embodiment, the initial dehumidification power is, for example, 75%, 70%, or 65% of the rated power.

[0044] By directly setting the initial dehumidification power to the preset value mentioned above, the current surge during startup can be effectively reduced, thus minimizing equipment wear.

[0045] To better understand the technical solutions of the embodiments of this application, the following provides a detailed explanation of determining the dehumidification power corresponding to each dehumidification moment.

[0046] In some embodiments, if the difference between the product of the initial dehumidification power and the dehumidification duration and the target dehumidification energy consumption is greater than a first preset threshold, the dehumidification power can be set to decrease from the initial dehumidification power to the first dehumidification power within the dehumidification duration, so that the absolute value of the deviation between the target dehumidification energy consumption and the actual dehumidification energy consumption is less than or equal to the first preset threshold. Wherein, the first dehumidification power is greater than or equal to 0.

[0047] If the difference between the target dehumidification energy consumption and the product of the initial dehumidification power and the dehumidification duration is greater than or equal to a first preset threshold, then the dehumidification power can be set to increase from the initial dehumidification power to a second dehumidification power within the dehumidification duration, and then decrease to a third dehumidification power. This ensures that the absolute value of the deviation between the target dehumidification energy consumption and the actual dehumidification energy consumption is less than or equal to the first preset threshold. The rate of change of the dehumidification power, as well as the second and third dehumidification powers, are determined based on the dehumidification duration and the target dehumidification energy consumption. The goal is to satisfy the following conditions: the absolute value of the deviation between the target dehumidification energy consumption and the actual dehumidification energy consumption is less than or equal to the first preset threshold; the second dehumidification power is less than or equal to the rated power; and the third dehumidification power is greater than or equal to 0.

[0048] To further reduce the impact of dehumidification equipment on power distribution equipment, the dehumidification duration can be set to be shorter than the shutdown duration. The first and third dehumidification powers correspond to the end time of the dehumidification duration. Since the first and third dehumidification powers may be greater than 0, a shutdown command can be sent to the dehumidification equipment at the end time of the dehumidification duration to cut off the power of the dehumidification equipment from the first or third dehumidification power.

[0049] To further achieve stable control of the dehumidification equipment, the aforementioned dehumidification information can be included in the dehumidification operating curve, so that the dehumidification equipment can be smoothly controlled based on the dehumidification power curve. Specifically: In some embodiments, the step of determining the dehumidification operating curve includes: Determine the curve construction conditions; wherein, the curve construction conditions include the initial dehumidification power as the ordinate of the curve starting point, the dehumidification time as the maximum abscissa of the curve, the maximum ordinate of the curve being less than or equal to the rated power, and the absolute value of the deviation between the target dehumidification energy consumption and the curve area being less than or equal to the first preset threshold. Based on the curve construction conditions, the dehumidification working curve is determined; the dehumidification working curve is used to characterize the dehumidification power corresponding to each dehumidification moment.

[0050] The dehumidification working curve mentioned above can be an elliptic curve segment.

[0051] In this embodiment, the dehumidification power corresponding to the maximum horizontal axis can be set as an adjustable parameter, that is, the endpoint power can be set as an adjustable parameter, and then the curvature can be adjusted until the absolute value of the deviation between the target dehumidification energy consumption and the curve area is less than or equal to the first preset threshold.

[0052] For example, the endpoint power can be initially set to a preset fourth dehumidification power. Then, the first integral area corresponding to the curve with the minimum curvature and the second integral area corresponding to the curve with the maximum curvature can be calculated. If the first integral area is less than the target dehumidification energy consumption and the second integral area is greater than the target dehumidification energy consumption, the curvature can be continuously adjusted until the absolute value of the deviation between the integral area corresponding to the curve and the target dehumidification power is minimized. If the first integral area is greater than the target dehumidification energy consumption, the endpoint power can be reduced according to a preset gradient to update the first and second integral areas. If the second integral area is less than the target dehumidification energy consumption, the endpoint power can be increased according to a preset gradient to update the first and second integral areas, until the updated first integral area is less than the target dehumidification energy consumption and the updated second integral area is greater than the target dehumidification energy consumption.

[0053] In this embodiment, by constructing the above-mentioned dehumidification operating curve and controlling the operation of the dehumidification equipment according to the above-mentioned dehumidification power curve, it is beneficial to improve the stable operation of the dehumidification equipment.

[0054] In some embodiments, satisfying the dehumidification conditions includes: If the actual humidity of the power distribution equipment is greater than or equal to the second preset threshold within the first preset time period, it is determined that the dehumidification condition is met.

[0055] The first preset duration is, for example, one hour or two hours, and the second preset threshold is, for example, 85% or 87%.

[0056] In this embodiment, the dehumidification condition is determined to be met only when the actual humidity within the first preset time period is greater than or equal to the second preset threshold. This helps to accurately identify the actual dehumidification needs and avoid energy waste caused by false triggering.

[0057] It should be understood that although the steps in the flowchart above are shown sequentially as indicated by the arrows, these steps are not necessarily executed in the order indicated by the arrows. Unless explicitly stated herein, there is no strict order restriction on the execution of these steps, and they can be executed in other orders. Moreover, at least some steps in the flowchart above may include multiple sub-steps or multiple stages. These sub-steps or stages are not necessarily completed at the same time, but can be executed at different times. The execution order of these sub-steps or stages is not necessarily sequential, but can be performed alternately or in turn with other steps or at least some of the sub-steps or stages of other steps.

[0058] like Figure 2 As shown in the figure, this application embodiment also provides a safe operation system for power distribution equipment, the system including: an edge computing fusion gateway, and at least one set of data acquisition devices connected and controlled by the edge computing fusion gateway.

[0059] The aforementioned data acquisition device includes a power acquisition terminal, a temperature acquisition unit, a partial discharge acquisition unit, and an input / output module. The data acquisition device is used to upload the acquired data to the edge computing convergence gateway.

[0060] The power acquisition terminal is installed inside the power distribution equipment; the partial discharge collector, temperature collector, and input / output module are installed outside the power distribution equipment.

[0061] The partial discharge acquisition device is connected to the partial discharge sensor in the power distribution equipment to collect partial discharge information in the power distribution equipment.

[0062] The temperature acquisition device is connected to the temperature sensor in the power distribution equipment to collect the temperature of the power distribution equipment.

[0063] The input / output module connects to an automatic fire extinguishing device, an anti-condensation device, and an access control sensor. The anti-condensation device includes the condensation sensor and semiconductor dehumidifier described in the above embodiments. Furthermore, the anti-condensation device also includes a salt spray concentration detector. Even further, the anti-condensation device includes an ultraviolet (UV) sterilization module, which operates in a timed start-up mode, for example, it can operate for 10 minutes every 24 hours. With a hygroscopic nano-coating applied to the inner wall of the cabinet to inhibit condensation formation, the UV sterilization module can effectively kill mold spores inside the cabinet.

[0064] Among them, reference Figure 2 As shown, corresponding data acquisition devices and sensors can be configured according to the voltage and environment of the power distribution equipment. Specifically: For the configuration of a 10kV ring main unit in a high-temperature and high-humidity area, the following method is adopted: Figure 2 The data acquisition devices and sensor settings are shown below. Specifically: Three-phase power acquisition terminals are used, installed on the internal rails of the cabinet, at least 0.6m above the ground, with one terminal per cabinet; temperature sensors are installed on the internal rails of the cabinet, with one terminal per ring main unit; temperature sensors are installed on the cable heads, one per phase; input / output modules are installed on the internal rails of the cabinet, 1.5 meters above the ground; and decondensation devices are installed on the internal rails of the cabinet, with one set per cabinet. After two years of normal operation using the above settings, a safety inspection was conducted, and no corrosion or mold was found.

[0065] For the configuration of transformers and 0.4kV outgoing switchgear in a power distribution room in a high-temperature and high-humidity area, the following approach is adopted: Figure 2 The connection method shown is suitable because its fault impact range is smaller compared to a 10kV ring main unit. Figure 2As shown, only some sensors or data acquisition devices are installed in the 10kV ring main unit. Furthermore, the specific installation and setup methods for sensors in the transformer and 0.4kV outgoing line cabinets are basically the same as those in the 10kV ring main unit. Following the above setup, after four years of normal operation, a safety inspection was conducted, and the results showed no corrosion or mold, but the cabinet sealing strips showed signs of aging.

[0066] Based on the aforementioned safe operation system for power distribution equipment, corrosion caused by high humidity and mold caused by high temperature and high humidity can be effectively avoided, making environmental control more holistic and systematic. This effectively avoids power distribution system anomalies caused by sudden power supply changes and also effectively avoids the negative impacts of drastic environmental changes.
