Description

Technical Field

[0001] This invention relates to the field of radiator equipment monitoring technology, specifically to a pressure detection and alarm system, method, and device for hydro-generator radiators. Background Technology

[0002] Hydropower generator sets, as the core equipment of hydropower generation, play a crucial role in power production. During operation, they generate a large amount of heat due to electromagnetic losses, mechanical friction, and other factors. If this heat cannot be dissipated in time, the unit's temperature will rise sharply, affecting its insulation and mechanical properties, and in severe cases, even causing equipment damage, power outages, and posing a significant threat to the safe and stable operation of the power system. Therefore, radiators are indispensable key components for ensuring the normal operation of hydropower generator sets. They dissipate the heat generated by the unit to the surrounding environment through the circulation of coolant, thereby maintaining the unit's normal operating temperature.

[0003] Currently, pressure testing of hydro-generator radiators is mainly conducted using simple pressure detection devices. These devices consist of a pressure sensor and a local display. The pressure sensor is installed at the radiator's inlet and outlet, detecting pressure in real time and transmitting the signal to the display, allowing staff to view the pressure values ​​on-site. However, this simple monitoring device can only display the pressure value and cannot perform in-depth analysis and processing of the pressure data. Staff must rely on experience and pressure changes to determine the location and severity of blockages, which increases the risk of misjudgment. Summary of the Invention

[0004] This invention provides a pressure detection and alarm system, method, and device for hydro-generator radiators, to solve the problems of inaccurate and inefficient judgment results when relying on human experience to determine the location and degree of blockage in hydro-generators.

[0005] In a first aspect, the present invention provides a pressure detection and alarm system for a hydro-generator radiator. The system includes: a pressure detector, a temperature sensor, and a data processing module. The pressure detector is used to collect first pressure data from the inlet pipe and second pressure data from the outlet pipe of the hydro-generator radiator. The temperature sensor is used to collect first temperature data from the inlet pipe and second temperature data from the outlet pipe of the hydro-generator radiator. The data processing module is used to determine pressure difference data based on the first and second pressure data, determine temperature difference data based on the first and second temperature data, determine the blockage location information and blockage degree information of the hydro-generator radiator based on the first pressure data, second pressure data, pressure difference data, first temperature data, second temperature data, and temperature difference data, and generate alarm information based on the blockage location information and blockage degree information.

[0006] The hydro-generator radiator pressure detection and alarm system provided by this invention includes a pressure detector, a temperature sensor, and a data processing module. By adding a temperature sensor, it simultaneously collects four key data points—pressure and temperature—from both the inlet and outlet, constructing a multi-dimensional monitoring matrix for pressure and temperature. This overcomes the blind spots of traditional single-parameter monitoring and comprehensively captures the operating status of the cooling system. With the help of the data processing module, the system can automatically calculate pressure and temperature differences, accurately identify the specific location of blockages and quantify their severity through multi-parameter collaborative analysis. This completely eliminates reliance on human experience, significantly reduces the risk of misjudgment, and effectively solves the problems of inaccurate and inefficient judgments based on human experience in determining the location and severity of blockages in hydro-generators.

[0007] In one optional implementation, the system further includes an alarm module; the alarm module is used to trigger an alarm based on alarm information.

[0008] In one optional implementation, the system further includes a data recording module; the data recording module is connected to the pressure detector, the temperature sensor and the data processing module respectively, and is used to store first pressure data, second pressure data, first temperature data, second temperature data and alarm information.

[0010] The method provided by this invention breaks through the limitations of traditional monitoring that relies solely on pressure parameters by simultaneously acquiring four types of key data—first pressure, first temperature, second pressure, and second temperature—from the inlet and outlet water pipes. It establishes a pressure and temperature collaborative monitoring system, which can more comprehensively and accurately reflect the operating status of the radiator and the entire cooling system, compensating for the blind spots of single-parameter monitoring. By automatically calculating pressure and temperature difference data and combining it with raw pressure and temperature data for multi-dimensional collaborative analysis, the specific location of blockages can be accurately located, and the severity of blockages can be quantified. This completely eliminates reliance on human experience, significantly reduces the probability of misjudgment, and makes fault diagnosis more scientific and accurate. Simultaneously, based on the analyzed blockage information, targeted alarm information is automatically generated, which can quickly trigger fault responses, prevent fault escalation, effectively ensure the continuous and stable operation of the generator set, and provide reliable technical support for the safe and efficient operation of the generator set.

[0011] In one optional implementation, the step of determining the blockage location and degree of blockage of the radiator of the hydro-generator unit based on first pressure data, second pressure data, pressure difference data, first temperature data, second temperature data, and temperature difference data includes: comparing the first pressure data with a preset first pressure fluctuation range to obtain a first comparison result; comparing the second pressure data with a preset second pressure fluctuation range to obtain a second comparison result; comparing the pressure difference data with a preset pressure threshold to obtain a third comparison result; determining a first temperature change gradient based on the first temperature data; determining a second temperature change gradient based on the second temperature data; determining a third temperature change gradient based on the temperature difference data; and determining the blockage location and degree of blockage based on the first comparison result, the second comparison result, the third comparison result, the first temperature change gradient, the second temperature change gradient, and the third temperature change gradient.

[0012] In one optional implementation, determining the blockage location information and blockage degree information based on the first comparison result, the second comparison result, the third comparison result, the first temperature change gradient, the second temperature change gradient, and the third temperature change gradient includes: determining the first blockage location and the first blockage degree based on the first comparison result, the second comparison result, and the third comparison result; determining the second blockage location and the second blockage degree based on the first temperature change gradient, the second temperature change gradient, and the third temperature change gradient; determining the blockage location information based on the first blockage location and the second blockage location; and determining the blockage degree information based on the second blockage location and the second blockage degree.

Detailed Implementation

[0019] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] It is understood that before using the technical solutions disclosed in the various embodiments of the present invention, users should be informed of the types, scope of use, and usage scenarios of the personal information involved in the present invention and their authorization should be obtained in accordance with relevant laws and regulations through appropriate means.

[0021] The terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this invention, "a plurality of" means two or more, unless otherwise explicitly specified.

[0022] In related technologies, simple pressure detection devices are mainly used to monitor the pressure of radiators in hydro-generator sets. These devices consist of a pressure sensor and a local display. The pressure sensor is installed at the inlet and outlet of the radiator, detecting the pressure in real time and transmitting the signal to the display, allowing staff to view the pressure values ​​on-site. However, this simple monitoring device can only display the pressure value and cannot perform in-depth analysis and processing of the pressure data. Staff must rely on experience and pressure changes to determine the location and severity of any blockages, which increases the risk of misjudgment.

[0023] Furthermore, most existing monitoring techniques focus only on pressure data, neglecting the impact of temperature on radiator operation. In reality, radiator temperature is also a crucial indicator of its operational status; abnormal temperatures could be a result of pressure anomalies or other malfunctions. The lack of temperature monitoring prevents the system from comprehensively and accurately assessing the radiator's operating condition.

[0024] In view of this, this application provides a pressure detection and alarm system for a hydro-generator radiator. The system provided by this invention includes a pressure detector, a temperature sensor, and a data processing module. By adding a temperature sensor, it simultaneously collects four key data points—pressure and temperature—from the inlet and outlet, constructing a multi-dimensional monitoring matrix for pressure and temperature. This overcomes the blind spots of traditional single-parameter monitoring and comprehensively captures the operating status of the cooling system. With the help of the data processing module, the system can automatically calculate pressure and temperature differences, accurately identify the specific location of blockages and quantify the severity of blockages through multi-parameter collaborative analysis. This completely eliminates reliance on human experience, significantly reduces the risk of misjudgment, and effectively solves the problems of inaccurate and inefficient judgments based on human experience in determining the location and severity of blockages in hydro-generators in related technologies.

[0025] This embodiment provides a pressure detection and alarm system for a hydro-generator radiator, such as... Figure 1 As shown, the system includes: a pressure detector 101, a temperature sensor 102, and a data processing module 103; The pressure detector 101 is used to collect first pressure data from the inlet pipe and second pressure data from the outlet pipe of the hydro-generator radiator. Exemplarily, the pressure detector 101 is a high-precision pressure sensor. The pressure detector 101 is pre-installed on the inlet and outlet pipes of the hydro-generator radiator to collect the pressure of the liquid within them. In this embodiment, the monitored radiator is the core component for heat dissipation in the hydro-generator. It has internal coolant flow channels where the coolant circulates, absorbing the heat generated by the hydro-generator and dissipating it to the surrounding environment through the radiator's cooling fins and other heat dissipation structures. The radiator's heat dissipation efficiency directly affects the operating temperature and operational stability of the hydro-generator. The pressure detector 101 includes at least one inlet pressure detector and at least one outlet pressure detector. The inlet pressure detector is installed on the inlet pipe, which connects the water source to the radiator and its main function is to supply coolant to the radiator. The coolant flows from the water source into the radiator through the inlet pipe, providing the necessary cold source for heat dissipation. The inlet pressure detector accurately and in real-time monitors the coolant pressure in the inlet pipe and converts the detected pressure signal into an electrical signal. This electrical signal can be an analog signal or a digital signal after analog-to-digital conversion for subsequent processing and transmission. The accuracy and stability of the inlet pressure detector are crucial for the accurate judgment of the system. The outlet pressure detector is installed on the outlet pipe, which connects the radiator to the coolant return system. Its function is to discharge the coolant from the radiator after heat exchange, allowing the coolant to be recycled. The coolant temperature rises after heat exchange and flows back to the cooling device through the outlet pipe for cooling before re-entering the inlet pipe to participate in the circulation. The outlet pressure detector is responsible for monitoring the coolant pressure in the outlet pipe in real-time and converting the pressure signal into an electrical signal output. The outlet pressure detector works in conjunction with the inlet pressure detector to provide the necessary pressure data to the data processor.

[0026] Specifically, the inlet pressure detector should be installed in a relatively stable location on the inlet pipe without significant vibration or interference. A high-precision pressure sensor should be installed at least 80cm from the radiator inlet to avoid water flow disturbance affecting detection accuracy. It should collect the first pressure data P1 in real time and convert it into an electrical signal. A suitable sealing connector should be used to connect the inlet pressure detector to the inlet pipe to prevent coolant leakage. During installation, ensure the detector is correctly oriented so that its pressure sensing element can fully contact the coolant to obtain accurate pressure data. The outlet pressure detector, with the same specifications as the inlet pressure detector, can be installed on the outlet pipe at a distance of 50cm from the radiator outlet. Ensure the probe is fully immersed in the coolant flow channel. It should collect the second pressure data P2 in real time and convert it into an electrical signal. Connect the signal cable of the detector, ensuring a secure connection and good insulation to prevent interference or signal loss during transmission. Connect the other end of the signal cable to the corresponding input port of the data processor.

[0027] The first pressure data, P1, reflects the water supply capacity of the inlet pipe and the upstream resistance. If the inlet or upstream pipe is blocked, the coolant flow is obstructed, and P1 will decrease. If the downstream (such as inside the radiator or at the outlet) is blocked, the coolant cannot drain smoothly, creating "back pressure" upstream, causing P1 to increase. The second pressure data, P2, reflects the drainage resistance of the water pipe and the downstream patency. If the outlet or downstream pipe is blocked, the coolant drainage is obstructed, and P2 will increase. If the inlet or upstream is blocked, the coolant flow rate decreases, and the downstream pressure will decrease as the flow rate decreases.

[0028] Temperature sensor 102 is used to collect the first temperature data of the water inlet pipe and the second temperature data of the water outlet pipe in the radiator of the hydro-generator set.

[0029] Exemplarily, in this embodiment of the application, the system may include multiple temperature sensors 102, and the number of temperature sensors 102 is not specifically limited in this embodiment. In this embodiment, the multiple temperature sensors 102 include at least one inlet water temperature sensor and at least one outlet water temperature sensor. The inlet water temperature sensor can be installed on the inlet pipe 30cm from the radiator inlet, with a distance ≥50cm from the inlet water pressure detector T1 to avoid the influence of water flow disturbance, and collects the first temperature data Tin in real time. The outlet water temperature sensor is installed on the outlet pipe 15cm from the radiator outlet, ensuring that the sensor probe is completely immersed in the coolant flow channel, and collects the second temperature data Tout in real time.

[0030] Specifically, the first temperature data, Tin, reflects the initial temperature of the coolant entering the radiator. Under normal circumstances, it is determined by the cooling water source temperature and the stability of the unit's heat generation, and its fluctuations are relatively small. If the inlet pipe is blocked, causing a reduction in flow rate, the coolant will stay on the water source side for a longer time (or its contact time with the unit will increase), and Tin may rise; if the water supply is sufficient, Tin will remain basically unchanged. The second temperature data, Tout, reflects the heat absorption effect of the coolant after passing through the radiator, and is directly related to the heat exchange efficiency. The core factor affecting heat exchange efficiency is the coolant flow rate: the greater the flow rate, the more heat is removed per unit time, and the lower the Tout; the smaller the flow rate, the less heat can be removed in time, and the higher the Tout. Therefore, an abnormal increase in Tout is usually a direct signal of insufficient flow rate, and the root cause of insufficient flow rate is blockage.

[0031] The data processing module 103 is used to determine pressure difference data based on the first pressure data and the second pressure data, determine temperature difference data based on the first temperature data and the second temperature data, determine the blockage location information and blockage degree information of the hydro-generator radiator based on the first pressure data, the second pressure data, the pressure difference data, the first temperature data, the second temperature data, and the temperature difference data, and generate alarm information based on the blockage location information and the blockage degree information.

[0032] For example, in this embodiment of the application, the pressure difference data is calculated using the following formula:

[0033] in, This represents the pressure difference data. This indicates the first temperature data. This indicates the second temperature data.

[0034] The temperature difference data is calculated using the following formula:

[0035] in, Represents temperature difference data. This indicates the second temperature data. This indicates the first temperature data.

[0036] In this embodiment of the application, pressure difference data It reflects the total resistance of the entire circulation system. Under normal circumstances, Determined by the frictional resistance along the pipe and the inherent resistance of the radiator, the value is relatively stable. However, when a blockage occurs in a certain part, the local resistance will change significantly, thus altering the... If the blockage occurs on the inlet side (such as the inlet), the increase in total resistance is not significant (only the upstream water supply decreases). It will decrease; however, if the blockage occurs on the middle side (inside the radiator) or the outlet side (outlet), the total resistance will increase significantly, making it difficult for water to drain downstream and for water to be forced in upstream. It will increase significantly. The temperature difference data ΔT directly reflects the heat exchange effect. Under normal flow conditions, the coolant can fully absorb heat, and ΔT is stable. When blockage causes a reduction in flow, although the coolant stays in the radiator for a longer time, the blockage of the heat exchange fins will reduce the heat exchange area, ultimately leading to a decrease in ΔT. The rate of decrease is positively correlated with the degree of blockage.

[0037] Specifically, the location of a blockage can be determined by observing the changes in inlet and outlet pressures, temperatures, temperature differences, and pressure differences. For example, if the outlet is blocked, downstream resistance increases sharply, P2 decreases (coolant cannot drain, downstream pressure drops), and back pressure forms upstream, causing P1 to increase, thus significantly increasing ΔT; reduced flow leads to decreased heat exchange efficiency, thus increasing Tout (heat cannot be carried away). If the blockage is severe, upstream back pressure will further increase Tin (coolant stagnates on the inlet side, absorbing more heat), ultimately forming the characteristic of "increased P1, decreased P2, increased ΔP, increased Tin / increased Tout". If the inlet is blocked, insufficient upstream water supply causes P1 to decrease, and reduced downstream flow causes P2 to decrease; insufficient flow leads to inadequate heat exchange, thus increasing Tout; if the blockage is minor, Tin may remain unchanged due to stable water source temperature, ultimately forming the characteristic of "decreased P1, decreased P2, decreased ΔP, unchanged Tin / increased Tout".

[0038] After determining the location of the blockage, the degree of blockage can be judged based on the deviation between the outlet pressure, temperature, temperature difference, and pressure difference and their respective preset thresholds.

[0039] Furthermore, the data processing module 103 can be implemented using a digital signal processor (DSP). A DSP has powerful data processing capabilities and a fast computing speed, enabling it to efficiently receive the electrical signals output by the inlet and outlet pressure detectors. The data processor processes these two pressure signals in real time, calculating the difference between the inlet and outlet pressures, and the changes in inlet and outlet temperatures. Simultaneously, the data processor is pre-set with multi-level positive and negative thresholds and temperature change judgment logic to determine whether there is blockage in the radiator's inlet or outlet pipes and the degree of blockage.

[0040] The data processor should be installed in a dry, well-ventilated environment that facilitates operation and maintenance, such as a dedicated electrical control cabinet. Secure the data processor firmly in its installation location to prevent vibrations or other factors from affecting its normal operation.

[0041] The system provided in this application includes a pressure detector, a temperature sensor, and a data processing module. By adding a temperature sensor, it simultaneously collects four key data points—pressure and temperature—from both the inlet and outlet, constructing a multi-dimensional monitoring matrix for pressure and temperature. This compensates for the blind spots of traditional single-parameter monitoring and comprehensively captures the operating status of the cooling system. With the help of the data processing module, the system can automatically calculate pressure and temperature differences. Through multi-parameter collaborative analysis, it accurately identifies the specific location of blockages and quantifies their severity, completely eliminating reliance on human experience and significantly reducing the risk of misjudgment. This effectively solves the problems of inaccurate and inefficient judgments based on human experience in determining the location and severity of blockages in hydro-generator units in related technologies.

[0042] In one optional implementation, the system further includes an alarm module; the alarm module is used to trigger an alarm based on alarm information.

[0043] For example, in this embodiment of the application, the alarm module includes an audible and visual alarm and a remote communication module. When the data processing module generates alarm information, the pressure anomaly alarm circuit will respond according to the specific situation.

[0044] In one optional implementation, the system further includes: a data recording module; The data recording module is connected to the pressure detector, temperature sensor and data processing module respectively, and is used to store the first pressure data, the second pressure data, the first temperature data, the second temperature data and alarm information.

[0045] For example, in this embodiment, the data recording module employs a large-capacity storage device to record historical pressure data and alarm information. It can use a large-capacity storage device, such as a hard drive or flash memory, to store radiator temperature, pressure data detected by the inlet water pressure detector and outlet water pressure detector, and alarm information triggered by the pressure anomaly alarm circuit in a time-series manner. The data recording module also has data management functions, such as data classification, querying, and statistics. Operators can use the data recording module to view the pressure changes and alarm records of the radiator at different time periods, enabling analysis and evaluation of the radiator's operating status and providing data support for equipment maintenance and fault prediction.

[0046] The following is a specific embodiment of the hydro-generator radiator pressure detection and alarm system provided in this application.

[0047] Example: This application provides a turbine generator set radiator pressure detection and alarm system, such as... Figure 2As shown, the system includes: the radiator being monitored 1, the inlet pipe 2, the inlet pressure detector 3, the outlet pipe 4, the outlet pressure detector 5, the data processor 6, the pressure abnormality alarm circuit 7, the electrical control cabinet 8, the inlet pipe temperature sensor 9, the outlet pipe temperature sensor 10, the audible and visual alarm 11, and the radiator body temperature sensor 12.

[0048] The monitored radiator 1 is the core component for heat dissipation in the hydro-generator set. It contains coolant flow channels where the coolant circulates, absorbing the heat generated by the generator set and dissipating it to the surrounding environment through the radiator's fins and other heat dissipation structures. The radiator's heat dissipation efficiency directly affects the operating temperature and stability of the generator set. The inlet pipe 2 connects the water source to the radiator, its main function being to supply coolant to the radiator. The coolant flows from the water source into the radiator through the inlet pipe, providing the necessary cooling source. The inlet pressure detector 3 is installed on the inlet pipe and typically uses a high-precision pressure sensor. It can accurately detect the pressure of the coolant in the inlet pipe in real time and convert the detected pressure signal into an electrical signal. This electrical signal can be an analog signal or a digital signal after analog-to-digital conversion for subsequent processing and transmission. The accuracy and stability of the inlet pressure detector are crucial for accurate system judgment. The outlet pipe 4 connects the radiator to the coolant return system, its function being to discharge the coolant from the radiator after heat exchange, allowing the coolant to be recycled. After heat exchange, the coolant temperature rises and flows back to the cooling device through the outlet pipe for cooling before re-entering the inlet pipe to participate in the circulation. The outlet pressure detector 5, also a high-precision pressure sensor, is installed on the outlet pipe. It is responsible for real-time detection of the coolant pressure in the outlet pipe and converting the pressure signal into an electrical signal output. The outlet pressure detector 5 works in conjunction with the inlet pressure detector to provide necessary pressure data to the data processor. The data processor 6 is implemented using a digital signal processor (DSP). The DSP 6 has powerful data processing capabilities and a fast computing speed, efficiently receiving the electrical signals output from both the inlet and outlet pressure detectors. The data processor processes these two pressure signals in real time, calculating the difference between the inlet and outlet pressures, and the changes in inlet and outlet temperatures. Simultaneously, the data processor has pre-set multi-level positive and negative thresholds and temperature change judgment logic to determine whether there is blockage in the radiator's inlet or outlet pipes and the degree of blockage. The pressure anomaly alarm circuit 7 includes an audible and visual alarm 11 and a remote communication module. When the data processor determines that the pressure difference exceeds the preset threshold range, the pressure abnormality alarm circuit will respond according to the specific situation.

[0049] The system also includes a data logging module. This module records historical pressure data and alarm information. It can utilize high-capacity storage, such as hard drives or flash memory, to store radiator temperature, pressure data detected by the inlet and outlet pressure detectors, and alarm information triggered by pressure anomaly alarm circuits in a time-series manner. The data logging module also features data management functions, such as data classification, querying, and statistics. Operators can use the data logging module to view radiator pressure changes and alarm records over different time periods, enabling analysis and evaluation of the radiator's operating status and providing data support for equipment maintenance and fault prediction.

Figure 3 This is a flowchart of a method for detecting and alarming the pressure of a hydro-generator radiator according to an embodiment of the present invention, as follows: Figure 3 As shown, the process includes the following steps: Step S301: Obtain the first pressure data and first temperature data of the water inlet pipe, and the second pressure data and second temperature data of the water outlet pipe in the radiator of the hydro-generator set.

[0053] Step S303: Based on the first pressure data, second pressure data, pressure difference data, first temperature data, second temperature data, and temperature difference data, determine the location and degree of blockage of the radiator of the hydro-generator unit. For example, please refer to the description of the relevant content in the above embodiments, which will not be repeated here.

[0054] Step S304: Generate alarm information based on the blockage location information and the degree of blockage information.

[0055] For example, the specific content of the alarm information can be determined according to actual needs, and this application embodiment does not impose specific limitations.

[0056] The pressure detection and alarm method for hydro-generator radiators provided in this embodiment breaks through the limitations of traditional monitoring methods that rely solely on pressure parameters by simultaneously acquiring four types of key data—first pressure, first temperature, second pressure, and second temperature—from both the inlet and outlet water pipes. This establishes a coordinated pressure and temperature monitoring system, providing a more comprehensive and accurate reflection of the radiator and the entire cooling system's operating status, thus overcoming the blind spots of single-parameter monitoring. By automatically calculating pressure and temperature differences and combining them with raw pressure and temperature data for multi-dimensional collaborative analysis, the method can accurately pinpoint the specific location of blockages and quantify their severity. This completely eliminates reliance on manual experience, significantly reducing the probability of misjudgment and making fault diagnosis more scientific and accurate. Simultaneously, based on the analyzed blockage information, the method automatically generates targeted alarm information, quickly triggering fault responses, preventing fault escalation, and effectively ensuring the continuous and stable operation of the generator set, providing reliable technical support for the safe and efficient operation of the generator set.

[0057] This embodiment provides a method for detecting and alarming the pressure of a hydro-generator radiator, which can be used in the aforementioned hydro-generator radiator pressure detection and alarm system. Figure 4 This is a flowchart of a method for detecting and alarming the pressure of a hydro-generator radiator according to an embodiment of the present invention, as follows: Figure 4 As shown, the process includes the following steps: Step S401: Obtain the first pressure data and first temperature data of the inlet pipe, and the second pressure data and second temperature data of the outlet pipe of the hydro-generator radiator. For details, please refer to [link to relevant documentation]. Figure 3 Step S301 of the illustrated embodiment will not be described again here.

[0058] Step S402: Determine the pressure difference data based on the first pressure data and the second pressure data; determine the temperature difference data based on the first temperature data and the second temperature data.

[0059] Step S403: Based on the first pressure data, the second pressure data, the pressure difference data, the first temperature data, the second temperature data, and the temperature difference data, determine the blockage location information and the degree of blockage information of the radiator of the hydro-generator unit.

[0060] Specifically, step S403 includes: Step S4031: Compare the first pressure data with the preset first pressure fluctuation range to obtain the first comparison result.

[0061] For example, a preset first pressure fluctuation range is used to characterize the allowable fluctuation range of the normal operating pressure on the inlet side. It is typically based on the rated inlet pressure of the equipment, fluctuating upwards and downwards by 10%-15% (specific values ​​should be referred to the equipment manual). For instance, if the rated inlet pressure of a hydro-generator radiator is 0.4 MPa, its P1 threshold can be set from 0.34 MPa (lower limit) to 0.46 MPa (upper limit). During normal operation of the radiator, P1 is stably controlled by the water supply system pressure, with minimal fluctuations. When blockage causes an increase in upstream resistance (e.g., inlet blockage) or a rise in downstream back pressure (e.g., outlet blockage), P1 will deviate from the threshold, and the magnitude of the deviation is positively correlated with the degree of blockage.

[0062] Step S4032: Compare the second pressure data with the preset second pressure fluctuation range to obtain the second comparison result.

[0063] For example, a preset second pressure fluctuation range is used to characterize the allowable fluctuation range of the normal operating pressure on the outlet side. It is typically based on the rated outlet pressure, fluctuating upwards and downwards by 15%-20% (the outlet pressure is more significantly affected by downstream pipe resistance, resulting in a slightly wider fluctuation range). For instance, if a radiator has a rated outlet pressure of 0.2 MPa, its P2 threshold can be set from 0.16 MPa (lower limit) to 0.24 MPa (upper limit). During normal radiator operation, P2 is determined by the unobstructed flow of the drainage system. When the outlet or downstream is blocked, P2 will increase due to drainage obstruction (exceeding the upper limit), and when the inlet is blocked, P2 will decrease due to reduced flow (below the lower limit).

[0064] Step S4033: Compare the pressure difference data with the preset pressure threshold to obtain the third comparison result.

[0065] For example, in this embodiment of the application, the preset pressure threshold is used to characterize the allowable fluctuation range of ΔP during normal operation. It is determined by the pipe friction resistance and the inherent resistance of the radiator, and is usually taken as ±10% of the average value of historical stable operating data. For example, if the average ΔP value of a radiator during normal operation is 0.2 MPa, its ΔP threshold can be set from 0.18 MPa (lower limit) to 0.22 MPa (upper limit). ΔP directly reflects the total resistance of the system and is the most critical pressure indicator for judging the degree of blockage. When there is mild blockage, the total resistance changes little, and ΔP deviates slightly from the threshold; when there is severe blockage, the total resistance increases sharply, and ΔP significantly exceeds the threshold range. That is, the deviation between ΔP and the preset pressure threshold is related to the degree of blockage of the radiator.

[0066] Step S4034: Determine the first temperature change gradient based on the first temperature data.

[0067] For example, the temperature change gradient refers to the rate of change of temperature parameters (Tin, Tout, ΔT) per unit time, which essentially reflects the rate of deterioration of heat exchange efficiency caused by blockage, and is usually expressed in "℃ / h". In the embodiments of this application, the first temperature change gradient represents the hourly change range of the inlet water temperature (Tin). During normal operation, the first temperature change gradient should be close to 0 (≤0.5℃ / h), and exceeding this value is considered a temperature anomaly.

[0068] Step S4035: Determine the second temperature change gradient based on the second temperature data.

[0069] For example, in this embodiment of the application, the second temperature change gradient represents the hourly change in the inlet water temperature (Tout). During normal operation, the second temperature change gradient should be close to 0 (≤0.5℃ / h). Exceeding this value is considered an abnormal temperature. For instance, if a radiator's Tout is stable at 35℃ during normal operation, and Tout rises to 38℃ within one hour, then dTout / dt = 3℃ / h, which far exceeds the normal gradient. dTout / dt represents the first temperature change gradient.

[0070] Step S4036: Determine the third temperature change gradient based on the temperature difference data.

[0071] For example, in this embodiment of the application, the third temperature change gradient dΔT / dt represents the hourly variation of the inlet and outlet water temperature difference. During normal operation, ΔT is stable (e.g., 5-8℃), and the gradient should be close to 0 (≤0.3℃ / h). When blockage leads to a deterioration in heat exchange efficiency, ΔT will decrease (dΔT / dt becomes negative, and its absolute value increases). For example, if a radiator normally has ΔT=7℃, and if ΔT drops to 5℃ within 1 hour, then dΔT / dt=-2℃ / h, indicating a significant decrease in heat exchange efficiency. ΔT directly reflects the heat exchange effect. Under normal flow conditions, the coolant can fully absorb heat, and ΔT is stable. When blockage leads to a reduction in flow, although the coolant stays in the radiator for a longer time, the blockage of the heat dissipation fins reduces the heat exchange area, ultimately leading to a decrease in ΔT. The rate of decrease (dΔT / dt) is positively correlated with the degree of blockage.

[0072] Step S4037: Based on the first comparison result, the second comparison result, the third comparison result, the first temperature change gradient, the second temperature change gradient, and the third temperature change gradient, determine the blockage location information and the blockage degree information.

[0073] In some optional implementations, step S4037 includes: Step a1: Determine the first blockage location and the first blockage degree based on the first comparison result, the second comparison result, and the third comparison result.

[0074] For example, in this embodiment of the application, the deviation of the first pressure data from a preset first pressure fluctuation range can be determined based on the first comparison result. Based on this deviation, the location of the blockage can be preliminarily determined. If the first pressure data is higher than the preset first pressure fluctuation range, it can be determined that there may be a blockage downstream of the radiator; if the first pressure data is lower than the preset first pressure fluctuation range, it can be determined that there may be a blockage at the radiator inlet or in the upstream pipe. After preliminarily determining the blockage location, the degree of blockage can be determined based on the deviation of the first pressure data from the preset first pressure fluctuation range. The degree of blockage can be characterized by a preset blockage degree evaluation value or blockage degree level. Similarly, the corresponding blockage location and degree of blockage can also be determined based on the second and third comparison results. The first blockage location is determined based on the blockage locations corresponding to the first, second, and third comparison results, and the first blockage degree is determined based on the blockage degrees corresponding to the first, second, and third comparison results.

[0075] Step a2: Determine the location and degree of the second blockage based on the first temperature change gradient, the second temperature change gradient, and the third temperature change gradient.

[0076] For example, in the embodiments of this application, the second blockage location and the second blockage degree are determined based on the first temperature change gradient, the second temperature change gradient and the third temperature change gradient.

[0077] Step a3: Determine the blockage location information based on the first blockage location and the second blockage location.

[0078] Step a4: Determine the degree of blockage information based on the second blockage location and the second degree of blockage.

[0079] For example, in the embodiments of this application, the degree of blockage is usually divided into three categories: mild, moderate and severe. It is necessary to combine the "pressure threshold deviation" and the "temperature change gradient" for comprehensive judgment. The synergistic effect of the two can avoid misjudgment by a single parameter.

[0080] In cases of mild blockage, pressure parameters deviate slightly from the threshold, with an abnormally slow gradient. P1 and P2 are close to the threshold range, deviating only slightly (e.g., P1 = 0.48 MPa, exceeding the upper limit by 0.46 MPa by approximately 4%; P2 = 0.15 MPa, falling below the lower limit by 0.16 MPa by approximately 6%). ΔP deviates slightly from the threshold; for example, normally ΔP = 0.2 MPa, but in mild blockage, ΔP = 0.24 MPa (exceeding the upper limit by 10%), or ΔP = 0.16 MPa (falling below the lower limit by 11%). The temperature change gradient is slightly abnormal, with dTin / dt ≤ 1℃ / h (e.g., Tin rising from 30℃ to 30.8℃ / h) and dTout / dt 1-2℃ / h (e.g., Tout rising from 35℃ to 36.5℃ / h). dΔT / dt: -0.5~-1℃ / h (e.g., ΔT decreases from 7℃ to 6.2℃ / h), ΔT is still on the edge of the normal range (e.g., near the lower limit of 5-8℃). In cases of mild blockage, the local flow channel only narrows slightly, the total resistance changes little, so the pressure deviates slightly from the threshold; the flow rate decreases little (≤20%), and the heat exchange efficiency decreases slowly, so the temperature gradient is only slightly abnormal. For example, when there is slight impurity accumulation on the inlet filter screen (P1 slightly decreases, ΔP slightly decreases, dTout / dt=1.2℃ / h) and slight scaling inside the radiator (ΔP slightly increases, dΔT / dt= -0.6℃ / h), the radiator is mildly blocked.

[0081] In moderate blockage, the local flow channel narrows significantly (diameter reduced by 30%-50%), leading to a substantial increase in total resistance and a significant deviation of the pressure from the threshold. The flow rate decreases considerably (20%-50%), resulting in a rapid decline in heat exchange efficiency and a significantly abnormal temperature gradient. In moderate blockage, the pressure parameter threshold deviation ranges from 20% to 50%. P1 and P2 significantly deviate from the threshold, such as P1 = 0.55 MPa (exceeding the upper limit of 0.46 MPa by approximately 20%) and P2 = 0.12 MPa (below the lower limit of 0.16 MPa by approximately 25%). ΔP significantly deviates from the threshold; for example, normally ΔP = 0.2 MPa, but in moderate blockage, ΔP = 0.3 MPa (exceeding the upper limit by 36%), or ΔP = 0.12 MPa (below the lower limit by 33%). dTin / dt: 1-2℃ / h (e.g., Tin increases from 30℃ to 31.8℃ / h), dTout / dt: 2-5℃ / h (e.g., Tout increases from 35℃ to 38.5℃ / h). dΔT / dt: -1~-3℃ / h (e.g., ΔT decreases from 7℃ to 5℃ / h), ΔT is below the lower limit of the normal range (e.g., below 5℃). For example, if 1 / 3 of the radiator's internal flow channels are clogged with scale (P1 increases, P2 decreases, ΔP increases significantly, dTout / dt = 3.5℃ / h), or if the outlet pipe is partially bent (P2 increases, ΔP decreases, dΔT / dt = -2.2℃ / h), then moderate blockage has occurred.

[0082] In cases of severe blockage, the local flow channel is almost completely blocked (diameter reduction > 50%), causing a sharp increase in total resistance and resulting in pressure deviating significantly from the threshold. Flow rate decreases sharply (> 50%), even approaching complete flow interruption, leading to a complete deterioration of heat exchange efficiency and a drastically abnormal temperature gradient, necessitating immediate shutdown and maintenance. P1 and P2 deviate significantly from the threshold by > 50%, such as P1 = 0.7 MPa (exceeding the upper limit by 0.46 MPa, approximately 52%) and P2 = 0.08 MPa (below the lower limit by 0.16 MPa, approximately 50%). ΔP deviates significantly from the threshold by > 50%, such as a normal ΔP = 0.2 MPa, but in severe blockage, ΔP = 0.4 MPa (exceeding the upper limit by 82%), or ΔP = 0.08 MPa (below the lower limit by 55%). dTin / dt: >2℃ / h (e.g., Tin rises from 30℃ to 33℃ / h), dTout / dt: >5℃ / h (e.g., Tout rises from 35℃ to 41℃ / h), and Tout is close to the equipment alarm temperature (e.g., 45℃). dΔT / dt: <-3℃ / h (e.g., ΔT drops from 7℃ to 3℃ / h), ΔT is far below the normal range (e.g., <4℃), and even "Tin=Tout" (complete heat exchange failure) occurs. For example, the inlet filter is completely blocked (P1 drops sharply, P2 drops sharply, ΔP drops significantly, dTin / dt=2.5℃ / h), and 2 / 3 of the flow channels inside the radiator are blocked (P1 rises sharply, P2 drops sharply, ΔP rises sharply, dTout / dt=6℃ / h), at which point moderate blockage occurs.
