Detailed Implementation

[0024] The exemplary embodiments of this disclosure are described below with reference to the accompanying drawings, including various details of the embodiments to aid understanding, and should be considered merely exemplary. Therefore, those skilled in the art will recognize that various changes and modifications can be made to the embodiments described herein without departing from the scope and spirit of this disclosure. Similarly, for clarity and brevity, descriptions of well-known functions and structures are omitted in the following description.

[0025] The following description, with reference to the accompanying drawings, outlines an excitation transformer cooling control method, apparatus, electronic device, and storage medium according to embodiments of the present disclosure.

[0026] Figure 1 This is a schematic flowchart of an excitation transformer cooling control method provided in an embodiment of the present disclosure.

[0027] like Figure 1 As shown, the method includes the following steps: Step 101: Monitor the operating temperature of the excitation transformer; This involves steps for real-time monitoring of the excitation transformer's operating temperature. This monitoring step is fundamental to ensuring the stable operation of the excitation transformer. By implementing temperature monitoring, the operating status of the excitation transformer can be grasped in a timely manner, providing crucial data support for subsequent cooling control and fault early warning.

[0028] Monitoring the operating temperature of the excitation transformer involves continuously collecting temperature data from key components of the transformer using temperature sensors. These key components typically include the windings and core of the excitation transformer, which are the primary heat-generating parts. The temperature sensors convert the collected temperature signals into readable data and transmit them to a monitoring system, such as a distributed control system (DCS). The monitoring system displays and records the received temperature data, generating a continuous temperature change curve for operators to observe and analyze.

[0029] Continuous monitoring of the operating temperature allows for the timely detection of abnormal temperature rise trends in the excitation transformer and the assessment of the current efficiency of the cooling system. Once the operating temperature exceeds the preset normal operating range, corresponding mechanisms are triggered, such as issuing alarms or activating auxiliary cooling equipment, effectively preventing equipment damage due to overheating and ensuring the safe and stable operation of the excitation transformer and the entire generator set. This monitoring step provides a crucial foundation for intelligent management and preventative maintenance of the excitation transformer.

[0030] Step 102: Generate a control signal based on the operating temperature to adjust the operating status of the external cooling fan; By automatically generating corresponding control commands through real-time analysis of operating temperature data, the operating mode of the external cooling fan is dynamically adjusted to ensure that the cooling efficiency matches the actual heat load of the excitation transformer. Generating control signals involves using a monitoring system such as a distributed control system (DCS) to process and judge the collected operating temperature data. When the temperature exceeds a preset threshold or abnormal fluctuations occur, the system automatically generates an electronic signal, which is transmitted to the drive unit of the external cooling fan through the control loop. Adjusting the operating status of the external cooling fan includes changing the fan's start / stop status, adjusting its speed or airflow output. For example, when the operating temperature is high, the fan is started or its speed is increased to enhance heat dissipation; when the temperature decreases, the fan's workload is reduced to save energy.

[0031] This closed-loop control mechanism based on temperature feedback can respond promptly to thermal changes in the excitation transformer, effectively preventing overheating, improving the adaptability and reliability of the cooling system, extending the service life of the fan, and reducing maintenance frequency. By implementing this step, intelligent management of the cooling process is achieved, avoiding delays and errors caused by manual intervention, and providing strong support for the safe and stable operation of the excitation transformer.

[0032] Step 103: When the external cooling fan fails, the fan replacement operation is performed during the operation of the excitation transformer.

[0033] By designing an externally mounted fan layout, non-stop maintenance is achieved. When the cooling system detects a fan fault signal or performance degradation, maintenance personnel can safely perform fan replacement work while the generator set is running continuously. The fan replacement operation includes a series of steps: identifying the faulty fan, disconnecting its power supply, disassembling the faulty unit and installing a backup fan, restoring power, and conducting test runs. Because the fan is located outside the excitation transformer enclosure and connected via an independent air duct, the replacement process does not require opening the enclosure or contacting the transformer body, thus maintaining a safe distance and ensuring the integrity of the equipment's insulation.

[0034] This improved the availability and ease of maintenance of the cooling system, avoided forced shutdown losses due to fan failure, and eliminated the safety risks and inefficiencies associated with temporary auxiliary cooling measures. By implementing this step, the continuous and reliable operation of the excitation transformer cooling system under high-temperature and high-load conditions was ensured, extending the overall lifespan of the equipment and reducing operation and maintenance costs and the frequency of manual intervention, thus providing effective assurance for the stability and economy of power production.

[0035] In some embodiments, the external cooling fan is configured to provide airflow output to meet enhanced cooling requirements.

[0036] This describes the configuration features of an external cooling fan. The external cooling fan is specifically designed and configured to provide airflow output that meets enhanced cooling requirements. Enhanced cooling requirements refer to the high-efficiency heat dissipation standards that must be achieved when the excitation transformer's heat generation increases significantly under high-temperature environments or high-load conditions, ensuring that the equipment's operating temperature remains within a safe range. The external cooling fan, employing a high-efficiency centrifugal impeller structure and an optimized drive unit, can generate a large volume of cooling airflow during continuous operation, with an airflow output far exceeding that of conventional cooling equipment. This achieves effective heat dissipation for critical components such as the excitation transformer windings and core. This enhanced airflow output can rapidly reduce the internal temperature of the excitation transformer, preventing insulation aging or equipment failure due to heat accumulation, while simultaneously improving the cooling system's response speed and reliability.

[0037] The fan configuration also considers the uniformity of air pressure and airflow distribution, ensuring that cooling air fully covers the heat-generating surfaces and avoids localized overheating. By meeting the enhanced cooling requirements, this external cooling fan not only significantly improves cooling efficiency but also reduces the system's reliance on temporary auxiliary cooling measures, enhancing overall operational stability and economy. This configuration balances performance and practicality, providing a solid foundation for the long-term safe operation of the excitation transformer under various harsh conditions.

[0038] In some embodiments, the external cooling fan is connected to the winding portion of the excitation transformer via an air duct with insulation and high-temperature resistance.

[0039] As a key component for conveying cooling airflow, the air duct's insulation performance ensures safe operation under high-voltage electrical environments, while its high-temperature resistance guarantees structural stability and functional reliability under continuous heating conditions of the excitation transformer. The air duct is made of special engineering materials, effectively isolating current and withstanding long-term high-temperature exposure, preventing cooling interruptions due to electric shock risks or thermal deformation.

[0040] The duct connection design directly guides the cooling air generated by the external cooling fan to the windings of the excitation transformer, achieving precise directional heat dissipation. This concentrates airflow to cover the most heat-prone areas, significantly improving cooling efficiency. This connection method reduces energy loss during airflow, ensuring that the cooling air reaches the target location with minimal resistance, while avoiding electrical interference with other transformer components. The insulation properties of the duct prevent leakage or short-circuit accidents, enhancing the overall system's safety margin; its high-temperature resistance maintains the duct's structural integrity and performance durability in high-temperature environments, preventing softening, embrittlement, or failure.

[0041] By optimizing the air duct layout and material selection, this design not only improves cooling uniformity but also reduces maintenance frequency and operating costs, extending the service life of the excitation transformer and its cooling system. This feature is a core element in achieving efficient, safe, and reliable cooling, providing a solid foundation for the stable operation of the excitation transformer under various operating conditions.

[0042] In some embodiments, generating a control signal based on the operating temperature to adjust the operating state of the external cooling fan includes: The cooling fan is activated when the operating temperature reaches the first temperature threshold. The cooling fan will stop when the operating temperature remains below the second temperature threshold.

[0043] Automatic start / stop control of the fan is achieved by setting a first temperature threshold and a second temperature threshold. When the monitored operating temperature reaches the first temperature threshold, the control system generates a start signal and sends it to the external cooling fan, driving it to start operating to enhance heat dissipation. The first temperature threshold is set to respond promptly to the temperature rise trend of the excitation transformer and prevent overheating. When the operating temperature remains below the second temperature threshold, indicating a significant reduction in cooling demand, the control system generates a stop signal and shuts down the external cooling fan, thereby avoiding unnecessary energy consumption and equipment wear. The second temperature threshold is typically set lower than the first temperature threshold to ensure that forced cooling is stopped only after the equipment temperature has sufficiently decreased. The dual-threshold control strategy enables intelligent operation of the cooling system, providing timely and effective cooling when needed while conserving resources and extending fan life during periods of low load. The entire control process requires no manual intervention, achieving precise temperature management through automatic monitoring and logical judgment. This significantly improves system efficiency and economy, while ensuring the safe and stable operation of the excitation transformer under various operating conditions.

[0044] In some embodiments, the wind turbine replacement operation is achieved through a quick-disassembly structure, and the main circuit connection of the excitation transformer is maintained during the replacement process.

[0045] A quick-release structure refers to a specially designed mechanical connection device, such as a snap-fit ​​interface, quick-release bolts, or a slide rail guide system, that allows the external cooling fan to be quickly removed and installed without the use of complex tools or lengthy operations. This structure typically includes components such as locating pins, locking handles, and standardized interfaces, ensuring that the connection between the fan and the duct is both secure and easy to separate, thus significantly reducing replacement time and simplifying manual operation. Maintaining the main circuit connection of the excitation transformer during the replacement process means that the entire fan replacement operation is carried out while the generator set is continuously running, without needing to disconnect the main power supply to the excitation transformer or interrupt its normal operation. This is thanks to the independent power supply and control circuit design of the external fan.

[0046] Maintaining the main circuit connection prevents unexpected downtime due to maintenance operations, ensuring the continuity and stability of power production. It also eliminates the power outage isolation steps and production losses associated with traditional built-in fan replacement. The combination of the quick-disassembly structure and the main circuit connection significantly improves the maintainability and availability of the cooling system, enabling maintenance personnel to safely and efficiently handle fan failures, reducing equipment downtime risks, and extending the overall system's lifespan. This feature reduces operating costs by optimizing the maintenance process, enhances the excitation transformer's adaptability to high-temperature, high-load environments, and provides a reliable guarantee for the safe and economical operation of the power plant.

[0047] In some embodiments, the method further includes: Maintenance prompts are automatically generated based on the operating time or changes in electrical parameters of the external cooling fan.

[0048] This invention relates to a maintenance and management method for an excitation transformer cooling system, specifically involving the step of automatically generating maintenance prompts based on the running time or changes in electrical parameters of an external cooling fan. This method continuously monitors the cumulative running time of the fan or the changing trends of key electrical indicators such as operating current, voltage, and power factor to assess and provide early warnings of the equipment's health status.

[0049] When the operating time reaches the preset maintenance cycle threshold or electrical parameters fluctuate abnormally beyond the normal range, the monitoring system will automatically trigger the signal generation module to generate a prompt message containing specific maintenance suggestions. This maintenance prompt message will be promptly conveyed to operators through audible and visual alarms on the monitoring interface or remote communication interfaces. The message may include recommendations to check the lubrication of the fan bearings, clean the cooling fins, or perform insulation tests, among other targeted maintenance items. Implementing this step upgrades the traditional periodic maintenance model to preventative maintenance based on the actual operating status of the equipment, effectively identifying potential faults and taking intervention measures at an early stage.

[0050] The maintenance strategy significantly reduced the probability of sudden wind turbine failures, avoided the risk of excitation transformer overheating due to cooling system failure, and reasonably extended the service life of the wind turbine while optimizing maintenance resource allocation. The function of automatically generating maintenance prompts reduced the burden of manual inspections, improved the scientific and systematic nature of maintenance management, and provided intelligent support for the long-term stable operation of the excitation transformer cooling system.
