Description

Technical Field

[0001] This invention relates to the field of power equipment regulation and control, and particularly to a method and system for substation operation control in high humidity environments. Background Technology

[0002] Substation equipment contains numerous electrical components. To dissipate the heat generated by these components, the substation equipment enclosure is equipped with through-holes to facilitate heat exchange between the inside and outside of the enclosure. These through-holes connect the internal air environment of the enclosure to the external atmospheric environment. During periods of high humidity, such as the "return to spring" weather, humid air from outside can seep into the enclosure through these through-holes, causing the internal moisture density to reach saturation. When the dew point temperature inside the enclosure decreases, the moisture inside condenses, forming dew that adheres to the surface of the electrical components. This dew can affect the insulation performance of the substation equipment and increase the risk of safety accidents such as high-voltage power line breakdown.

[0003] Currently, the main methods for suppressing condensation in substation equipment include placing moisture-absorbing materials inside the enclosure. However, these methods require regular replacement of the materials and occupy additional internal space, and the absorption efficiency cannot be actively controlled in high-humidity environments. Furthermore, existing condensation suppression methods do not fully utilize or effectively control the ventilation systems installed in the substation equipment itself. They cannot precisely regulate the operation of the ventilation systems based on the spatial distribution of heat and humidity within the enclosure, reducing the dehumidification efficiency and controllability of the substation in high-humidity environments, and thus compromising the operational safety of the substation. Summary of the Invention

[0004] Considering that the existing dehumidification operations in substations under high humidity conditions do not fully utilize and effectively control the original ventilation devices, and cannot accurately adjust the operation of the ventilation devices according to the real-time spatial distribution of heat and humidity in the substation under high humidity conditions, the dehumidification efficiency and controllability are reduced.

[0069] Please see Figure 1 As shown in this application, an embodiment of the substation operation control method for high humidity environments provides the following:

[0070] Step S1: Construct a three-dimensional model of the substation; determine the air convection state within the substation based on the air exchange configuration conditions, and establish the air flow field in the three-dimensional model accordingly.

[0071] Step S2: Obtain the associated temperature data of the substation, estimate the internal and external heat exchange state, and establish a heat field in the three-dimensional model accordingly; obtain the associated humidity dynamic data of the substation, estimate the humidity change trend, and establish a humidity field in the three-dimensional model accordingly.

[0072] Step S3: Based on the air flow field, perform dynamic evolution analysis on the heat field and humidity field to obtain the water vapor changes within the substation; based on the water vapor changes, identify potential risk areas within the substation.

[0073] Step S4: Apply boundary conditions based on the potential risk area and the active convection of the substation to control the active convection operation status of the substation.

[0074] This substation operation control method for high humidity environments constructs a three-dimensional model of the substation and establishes air flow field, heat field, and humidity field within the three-dimensional model. This enables multi-modal coupling identification within the substation space, precise control of active convection within the space, and improved dehumidification efficiency and substation operation safety.

[0075] In another embodiment, in step S1, a three-dimensional model of the substation is constructed; based on the air exchange configuration conditions of the substation, the air convection state within the substation is determined, thereby establishing an airflow field in the three-dimensional model, including:

[0076] Acquire the three-dimensional morphological data and three-dimensional connection relationships of all components within the substation; the three-dimensional morphological data includes three-dimensional dimensions and spatial layout.

[0077] Simulation modeling is performed based on 3D morphological data and 3D connection relationships to construct a 3D model of the substation; the 3D model includes the full-size layout and void layout of all components within the substation.

[0078] Obtain the hardware configuration conditions for internal and external air exchange in the substation; the hardware configuration conditions include the configuration of active air exchange hardware space and operating parameters, as well as the configuration of passive air exchange hardware space.

[0079] Based on the configuration of internal and external air exchange hardware and the layout of gaps, the air convection state within the substation is determined; the air convection state includes the air convection path and the air convection velocity; the air convection state is mapped onto a three-dimensional model to establish an air flow field.

[0080] As a high-voltage power transmission relay station, a substation performs both voltage conversion and insulation functions. To achieve these multiple functions, various types of electrical components are installed within the substation, including but not limited to control cabinets, switchgear, and GIS (Gas Insulation System) components. It is understood that control cabinets primarily support the substation's voltage conversion function; switchgear primarily supports the substation's start / stop state switching function; and GIS components, as insulating components, provide a good insulating working environment for the substation. The substation also features an enclosure where all electrical components are housed. Considering the heat generated during operation, to prevent heat accumulation and overheating inside the enclosure, both active and passive air exchange hardware are installed. Active air exchange hardware may include, but is not limited to, cooling fans and / or air conditioners; passive air exchange hardware may include, but is not limited to, ventilation holes. Active and passive air exchange hardware can be installed on the side walls of the enclosure. During operation, the active air exchange hardware creates air convection within the enclosure and, with the help of the passive air exchange hardware, forms air circulation with the external atmosphere, thereby dissipating heat from inside the enclosure to the outside atmosphere, effectively achieving heat dissipation. Furthermore, the internal space of a substation enclosure is limited, and multiple electrical components are located within it. These components, distributed in different locations within the enclosure, affect the air convection path and velocity. It is understandable that air convection within the enclosure primarily occurs in the gaps between different electrical components; the larger the gaps, the stronger the air convection.

[0081] As discussed above, the size and spatial arrangement of electrical components inside a substation enclosure directly affect the path and intensity of air convection within the enclosure. To obtain a comprehensive 3D model of the substation enclosure's interior, it is necessary to construct a global model of the enclosure's interior. Please refer to [link / reference]. Figure 2 First, the three-dimensional dimensions and spatial layout of all electrical components inside the substation, as well as the connection relationships between any two electrical components, are obtained. These connection relationships may include, but are not limited to, the three-dimensional spatial form of the connecting parts between two electrical components. Then, simulation modeling is performed on the three-dimensional dimensions and spatial layout of the electrical components and the connection relationships between them to construct a three-dimensional model of the substation. This model comprehensively represents the full-size layout and void layout of all electrical components inside the substation enclosure, providing precise spatial constraints for the subsequent establishment of the airflow field.

[0082] As discussed above, the active air exchange hardware within a substation, in conjunction with passive air exchange hardware, creates air convection within the substation. This air convection is influenced by the size and spatial arrangement of the electrical components within the substation, confining the airflow within the gaps between these components and also affecting the airflow velocity. It is understandable that the spatial arrangement and operating parameters of the active air exchange hardware (such as the installation location and rotational speed of the cooling fans), and the spatial configuration of the passive air exchange hardware (such as the installation location and opening size of the ventilation holes), will affect the airflow field created by the combined action of the active and passive air exchange hardware within the substation. Please refer to [link / reference]. Figure 3 This study investigates the airflow field in a cross-section of the substation's internal space near ventilation openings. In practice, the active air exchange hardware space and its operating parameters, as well as the passive air exchange hardware space configuration and the internal gap layout of the substation, are acquired. This allows for the determination of air convection paths and velocities within the substation. These air convection paths and velocities are then mapped onto the aforementioned three-dimensional model to establish the airflow field within the substation. This comprehensive characterization of the actual air convection conditions within the substation provides a basis for subsequently determining the water vapor accumulation situation within the substation.

[0083] In another embodiment, in step S2, associated temperature data of the substation is acquired, and the internal and external heat exchange state is estimated to establish a heat field in the three-dimensional model; associated humidity dynamic data of the substation is acquired, and the humidity change trend is estimated to establish a humidity field in the three-dimensional model, including:

[0084] Collect first temperature data from several locations inside the substation and second temperature data from several locations outside the substation;

[0085] Based on the substation's own heat transfer characteristic parameters, first temperature data, and second temperature data, the heat exchange state between the substation's internal and external spaces is estimated. The heat exchange state includes the heat transfer direction and heat transfer flow rate. The heat exchange state is then mapped in three dimensions to establish a heat field in a three-dimensional model.

[0086] Collect first dynamic humidity data from several locations inside the substation and second dynamic humidity data from several locations outside the substation;

[0087] By comparing the first and second humidity dynamic data, the humidity change trend of the internal space is obtained; the humidity change trend is mapped in three-dimensional space to establish a humidity field in the three-dimensional model.

[0088] The heat inside a substation directly determines its internal temperature. Water vapor can only condense into dew when the internal temperature is below the dew point. Electrical components inside the substation generate heat during operation, and this heat exchange with the outside environment through the substation's enclosure causes temperature changes. Therefore, the global heat distribution within the substation directly determines the temperature distribution. Establishing a global heat field within the substation accurately characterizes the global heat distribution and provides a basis for predicting water vapor accumulation trends. In practice, temperature data is collected at several locations inside and outside the substation. Combined with the substation's own heat transfer characteristics (such as the thermal conductivity of various parts of the enclosure), the heat exchange state between the internal and external spaces is estimated. This accurately characterizes the direction of heat transfer (whether heat is transferred from the internal space to the external space or vice versa) and the heat transfer rate (the heat transfer value per unit time) in each area of ​​the substation. Finally, the aforementioned heat exchange states are mapped onto a three-dimensional model to establish a heat field, accurately representing the global distribution of heat values ​​within the substation's interior space. Please refer to [link / reference]. Figure 4 The heat field of a cross-section of the internal space of the strain gauge power plant near the ventilation opening, from Figure 4 It is evident that the area near the ventilation openings inside the substation has less heat (i.e., lower temperature), while the area farther away from the ventilation openings has more heat (i.e., higher temperature).

[0089] The substation's internal and external spaces are connected by ventilation openings, allowing moisture from the external space to enter the internal space, increasing the relative humidity. Only when the internal relative humidity reaches a preset threshold will the moisture condense into dew. Understandably, higher relative humidity makes dew formation more likely. Establishing a global humidity field within the substation accurately characterizes the distribution of relative humidity values, providing a basis for predicting moisture accumulation trends within the substation. In practice, dynamic relative humidity data is collected at several locations both inside and outside the substation. Based on the water vapor transport pattern from areas of higher to lower relative humidity, the dynamic relative humidity data from the internal and external spaces are compared to obtain the humidity change trend within the internal space. This trend is then mapped onto a 3D model to establish a humidity field, accurately representing the global relative humidity distribution within the substation's internal space. Please refer to [link to relevant documentation]. Figure 5 The humidity field of a cross-section of the internal space of the strain gauge power plant near the ventilation opening, from Figure 5 It is evident that the relative humidity values ​​vary depending on the distance between the interior space of the substation and the ventilation opening.

[0090] In another embodiment, in step S3, based on the airflow field, a dynamic evolution analysis of the heat field and humidity field is performed to obtain the water vapor changes within the substation; based on the water vapor changes, potential risk areas within the substation are identified, including:

[0091] Based on the air flow field, the air flow dynamic distribution within the substation is determined; using the air flow dynamic distribution, the dynamic evolution of the heat field and humidity field is analyzed to obtain the multimodal water vapor changes within the substation; among which, the multimodal water vapor changes include changes in water vapor concentration and changes in water vapor diffusion motion.

[0092] Based on multimodal water vapor changes, the trend of water vapor accumulation concentration changes throughout the substation is estimated, thereby identifying potential risk areas within the substation.

[0093] The airflow field within a substation provides the driving force for heat and moisture transfer. Heat and moisture change spatially with airflow. Understandably, the higher the airflow velocity, the faster and wider the heat and moisture transfer and diffusion. Furthermore, heat transfer and diffusion also affect moisture transfer and diffusion; higher heat makes moisture accumulation more difficult. Only when the heat is below a preset threshold will moisture transfer not be affected (e.g., the moisture concentration will not decrease due to evaporation during transfer). To accurately predict moisture transfer and accumulation caused by airflow within a substation, the dynamic distribution of airflow during the airflow process (i.e., the airflow-driven dynamic distribution) is determined based on the aforementioned airflow field. Then, based on this dynamic distribution, the dynamic evolution of the heat and humidity fields is analyzed to obtain multimodal moisture changes within the substation, accurately characterizing the dynamic changes in moisture concentration and diffusion motion (specifically, the direction of diffusion motion) within the substation. Furthermore, based on the aforementioned multimodal water vapor changes, the dynamic movement of water vapor in the internal space of the substation can be effectively predicted, thereby estimating the trend of water vapor accumulation concentration changes across the entire internal space of the substation, and thus identifying potential risk areas within the internal space of the substation. These potential risk areas refer to regions where the water vapor accumulation concentration in the internal space of the substation exceeds a preset concentration threshold.

[0094] In another embodiment, in step S4, boundary conditions are applied based on the potential risk area and the active convection of the substation to control the active convection operation state of the substation, including:

[0095] By comparing the spatial distribution of potential risk areas with the spatial distribution of active air exchange hardware within the substation, the effective active air exchange hardware is identified.

[0096] Based on the active convection execution boundary conditions of each effective active air exchange hardware, the operating strategy of each effective active air exchange hardware is generated; wherein, the active convection execution boundary conditions include the range of convection disturbance direction and intensity of each effective active air exchange hardware.

[0097] Based on the operational strategy, the active convection operation status of each effective active air exchange hardware is adjusted in a time-differentiated manner.

[0098] As described above, active air exchange hardware can proactively generate controllable air convection within the substation's internal space. To prevent the continuous accumulation of moisture in potential risk areas, this active air exchange hardware needs to guide the moisture accumulated in these areas to diffuse into the external space. In practice, by comparing the spatial distribution of potential risk areas with the spatial distribution of active air exchange hardware within the substation, active air exchange hardware whose actual distance from these potential risk areas is within a preset distance range is identified as effective active air exchange hardware. Then, based on the convective disturbance direction range (e.g., the range of the active air exchange hardware's rotational angle) and intensity range (e.g., the range of the active air exchange hardware's blade rotation speed), an operating strategy is generated for each effective active air exchange hardware. This operating strategy may include, but is not limited to, the rotational angle and blade rotation speed of the active air exchange hardware. Based on these operating strategies, the active convection operation state of each effective active air exchange hardware is adjusted in a time-differentiated manner. For example, each effective active air exchange hardware can be controlled to operate according to its corresponding operating strategy at different time periods, thereby improving the efficiency of expelling moisture from the substation's internal space to the external space.

[0099] Please see Figure 6 As shown in one embodiment of this application, a substation operation control system for high humidity environments is provided. This substation operation control system for high humidity environments includes:

[0100] The modeling module is used to build a 3D model of the substation.
