[0041] Embodiments of the present disclosure are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout identify the same or similar originals or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present disclosure, and should not be construed as limiting the present disclosure.

[0042] First, a brief introduction to the relevant terms in this disclosure is given:

[0043] Turbine Supervisory Instrument (TSI): In this disclosure, it refers to a permanent monitoring system that integrates protection and detection functions, mainly used for safety monitoring of large rotating machinery such as steam turbines. The TSI system can monitor the key parameters of the steam turbine during startup and operation in real time, and provide functions such as data recording, alarm and automatic shutdown. For parameter monitoring, the TSI system can reliably monitor important parameters such as the speed, vibration, shaft displacement, temperature, etc. of the steam turbine. For alarm and protection, when the monitored parameters exceed the set range, the system will sound an alarm and can automatically shut down to prevent equipment damage. For data recording, the system can record operating data and provide necessary information support for fault diagnosis. The TSI system is widely used in various steam turbine generator sets ranging from 3MW to 600MW to ensure their safe and efficient operation. Through continuous monitoring of important parameters, the TSI system helps operators to judge the status of the machine in a timely manner, thereby effectively preventing accidents.

[0044] In power plants, the TSI system of generator sets currently uses Emerson's MMS6000 system to be put into operation together with the units. The system operation has problems such as system aging, shutdown of some spare parts, and complex system wiring. The detection data sometimes jumps, threatening the safe and stable operation of the units. In related technologies, the shaft vibration monitoring logic does not meet the relevant requirements of 9.4.3 of the 25 countermeasures in the "25 Key Requirements for Preventing Power Production Accidents (2023 Edition)" issued by the National Energy Administration. All important main and auxiliary machine protections should adopt the "three out of two" logical judgment method. The protection point signal should follow the principle of relative independence from the sampling point to the input module. If the number of measurement points is insufficient due to system reasons, measures should be taken to prevent false protection. The equipment status in related technologies can no longer meet the needs of safe and stable operation of the unit, and there are major safety hazards. The distribution of some boards in the TSI system violates the above regulations, and the damage of a single card has a great impact on the monitoring and protection of the unit. The shaft vibration and displacement measurement points do not meet the requirements of risk dispersion.

[0045] The present disclosure aims to solve the problem in the related art that the monitoring modules of the TSI system are numerous and not uniform, and the reliability of monitoring and protection is low, and the operation status of the steam turbine cannot be truly reflected. The multiple shaft displacement measurement points of the TSI system are dispersedly arranged on multiple monitoring modules, that is, the shaft vibration measurement points of the TSI system are dispersedly arranged, which greatly improves the dispersion of important measurement points and the reliability of monitoring and protection.

[0046] The method proposed in the present disclosure is applied to the TSI protection monitoring task of the steam turbine, and its application has a rich variety of scenarios, including the power industry, especially in the monitoring and protection of steam turbine generator sets, to ensure the safe operation of the equipment and fault warning; in the field of oil and gas, the state of rotating machinery is monitored in oil drilling and natural gas processing facilities to prevent equipment failure; in the chemical industry, it is used for monitoring large rotating equipment in chemical production to ensure the safety of the production process; in the metallurgical industry, the operating state of related mechanical equipment is monitored during smelting and metal processing to improve production efficiency; in the aerospace field, key components are monitored in real time in aircraft engines and spacecraft to ensure safety and reliability; in the manufacturing industry, the operating state of equipment is monitored during the manufacturing process of large machinery to reduce the failure rate and improve production efficiency; and in the field of scientific research, it is used for real-time monitoring and data analysis of experimental equipment when researching and developing new materials or new technologies. Through these application scenarios, the technical solution can significantly improve the safety and reliability of various types of industrial equipment. The application scenarios are not limited in the embodiments of the present disclosure.

[0047] The steam turbine TSI protection monitoring method provided by the present disclosure is described in detail below with reference to the accompanying drawings.

[0048] Figure 1 FIG. 4 is a flow chart of a steam turbine TSI protection monitoring method according to an embodiment of the present disclosure. Figure 1 In the embodiment shown, the steam turbine TSI protection monitoring method includes:

[0049] Step 101: Use a universal monitoring module to collect operating data at different positions of the steam turbine. The universal monitoring module has at least two data channels, and the two data channels support data transmission of different types of sensors.

[0050] In this embodiment, the universal monitoring module refers to a device for monitoring various operating data of the steam turbine, and has at least two data channels, and the two data channels support data transmission of different types of sensors. The operating data refers to various data of the steam turbine in working state collected by various sensors in the universal monitoring module.

[0051] The operation data of the steam turbine is collected by deploying universal monitoring modules at different locations of the steam turbine.

[0052] Step 102: If the number of abnormal data points in the operating data is greater than or equal to a preset number, an alarm is issued that the location of the abnormal data point is abnormal, and a protection mechanism of the steam turbine is triggered.

[0053] In this embodiment, the abnormal data point refers to the detection point where the abnormal data detected in the operating data is located. The protection mechanism of the steam turbine refers to a system that ensures that the steam turbine can operate safely and reliably under various abnormal conditions, including but not limited to overspeed protection, electronic protection system and crisis isolation system.

[0054] If the number of abnormal data points in the operating data is greater than or equal to the preset number, it means that a large amount of abnormal data has appeared in the operating data, then an alarm is issued to indicate that an abnormality has occurred at the location where the abnormal data points are located, and the protection mechanism of the steam turbine is triggered.

[0055] In summary, according to the turbine TSI protection monitoring method proposed in the present invention, a universal monitoring module is used to collect operating data at different positions of the turbine, providing original data for the monitoring and protection of the turbine; the universal monitoring module has at least two data channels, and the two data channels support data transmission of different types of sensors. By using a unified monitoring module, the spare parts cost is reduced; if the number of abnormal data points in the operating data is greater than or equal to a preset number, the location of the abnormal data point is alarmed to be abnormal, and the protection mechanism of the turbine is triggered, providing a reliable basis for the protection monitoring of the turbine.

[0056] Figure 2 The present invention is a flow chart of using a universal monitoring module to collect operating data of a steam turbine according to an embodiment of the present invention. Figure 2 Yes Figure 1 Further explanation of step 101 is based on Figure 2The embodiment shown comprises the following steps:

[0057] Step 201, based on the universal monitoring module, real-time acquisition of displacement, shaft vibration, cylinder expansion, speed, eccentricity and key phase data of the steam turbine, wherein the shaft vibration is composed of the displacement values ​​of the shaft displacement of the steam turbine in both the horizontal and vertical directions.

[0058] In this embodiment, the shaft vibration of the steam turbine refers to a set of values ​​consisting of the displacement values ​​of the shaft displacement of the steam turbine in the horizontal axis x and the vertical axis y. Cylinder expansion usually refers to the expansion phenomenon of the cylinder of the steam turbine under temperature changes or mechanical stress. This expansion may cause the gap between the cylinder and the rotor to change, thereby affecting the normal operation of the steam turbine. Cylinder expansion may be caused by a variety of factors, including temperature rise or temperature drop during startup or shutdown, changes in mechanical load, etc. These factors may cause the physical dimensions of the cylinder to change, thereby affecting the performance and safety of the entire steam turbine. Monitoring cylinder expansion is crucial to ensure the safe operation of the steam turbine. By monitoring cylinder expansion, potential problems can be discovered in time and corresponding measures can be taken to prevent accidents. For example, if it is found that the cylinder expansion is too large, it may be necessary to adjust the operating parameters or perform maintenance. Eccentricity refers to the phenomenon that the mass center of the rotor does not coincide with the geometric center during rotation. This deviation may be caused by material processing errors, inaccurate assembly, or wear caused by long-term operation. The measurement of eccentricity is usually completed using an eddy current sensor. The sensor is installed on the bearing housing of the steam turbine. When the rotor rotates, the sensor detects small changes in the rotor surface and calculates the eccentricity value. The presence of eccentricity affects the balance state and vibration characteristics of the steam turbine, so it needs to be monitored and corrected regularly. If the eccentricity value exceeds the allowable range, it may cause unstable operation of the steam turbine or even cause serious mechanical failure. Key phase is a technology used to determine the position of the rotor. It is achieved by setting specific marks (such as grooves or convex keys) on the rotor and using sensors to detect the position of these marks. Key phase is mainly used to measure the speed and vibration phase angle. By analyzing the key phase signal, the real-time position and speed of the rotor can be understood, which is very important for dynamic balancing analysis and fault diagnosis. Key phase monitoring can help engineers identify the unbalanced state and other potential problems of the rotor, so that timely measures can be taken to adjust it. This is of great significance to maintain the efficient operation of the steam turbine and extend the life of the equipment. Cylinder expansion, eccentricity and key phase are three key monitoring parameters in the operation of steam turbines in thermal power plants. They are related to the physical structural stability of the steam turbine, the balance state of the rotor and the accurate measurement of the rotor position. Through strict monitoring and management of these parameters, the occurrence of faults can be effectively prevented and the operating efficiency and safety of the steam turbine can be improved. Using the universal monitoring module, the displacement, shaft vibration, cylinder expansion, speed, eccentricity and key phase data of the steam turbine are collected in real time, providing the original data for the monitoring and protection of the steam turbine.

[0059] Figure 3 The present invention is a flowchart of deploying a universal monitoring module in a steam turbine according to an embodiment of the present invention. Figure 3 Yes Figure 1 Further explanation of step 101 before, based on Figure 3 The embodiment shown comprises the following steps:

[0060] Step 301: Distribute a first number of sensors on a plurality of universal monitoring modules, and directly transmit the data collected by the sensors to a data processing board via the universal monitoring modules.

[0061] In this embodiment, the data processing board refers to a hardware device used to analyze and process monitoring data, which is responsible for receiving, processing and analyzing signals from various sensors to ensure the safe operation of the steam turbine. The first number of sensors are dispersedly arranged on multiple universal monitoring modules, that is, various sensors are deployed in each universal monitoring module. The "three out of two" logical judgment method is adopted to protect the detected signal from following the principle of relative independence from the sampling point to the input data processing board, so as to prevent the damage of a single universal monitoring module or card from causing false alarms of the unit safety monitoring results.

[0062] Step 302: deploy multiple universal monitoring modules at different locations of the steam turbine.

[0063] In this embodiment, a plurality of universal monitoring modules are deployed at different positions of the steam turbine to ensure that complete and reliable operation data of the steam turbine are collected.

[0064] In one implementation of this embodiment, Table 1, Table 2 and Table 3 are operating data collected by sensors arranged in the monitoring module in the related art.

[0071] The contents of Table 1, Table 2 and Table 3 are combined, that is, the 27 sensors in the related technology are arranged in a single monitoring module A6500-UM for data collection, and 27 sets of data are obtained. As long as any value exceeds the set range, the protection mechanism of the turbine can be triggered.

[0072] The collection points in Table 1 are monitored by universal monitoring module 1, the collection points in Table 2 are monitored by universal monitoring module 2, and the collection points in Table 3 are monitored by universal monitoring module 3. The abnormal monitoring points among the three universal monitoring modules are determined by the operation data of the three universal monitoring modules, and the abnormal monitoring modules among the universal monitoring modules are determined by the "three-choose-two" principle. Optionally, if the three are in the same position of the steam turbine, then whether two of the three are abnormal monitoring modules, if so, it means that the position where the universal monitoring module is deployed in the steam turbine fails. By the dispersed deployment of the collection points and universal monitoring modules in this embodiment, the false alarm of the steam turbine failure is effectively avoided, and the reliability of the steam turbine monitoring and protection is improved.

[0073] Figure 4 The present invention is a flowchart of a protection mechanism for triggering a steam turbine according to an embodiment of the present invention. Figure 4 Yes Figure 1 The specific description of step 102 is based on Figure 4 The embodiment shown comprises the following steps:

[0074] Step 401, determining abnormal data points through the value range of each point data in the running data.

[0075] In this embodiment, the data collected at each detection point in the operating data is compared with a preset value range. If the collected data is within the value range, the collected data is normal. If the collected data is not within the value range, it means that the collected data is abnormal, and the point where the collected data is abnormal is the abnormal data point.

[0076] Step 402: Count the number of abnormal data points as the number of abnormal point numbers.

[0077] In this embodiment, all abnormal data points in the operating data are counted, and the number of abnormal data points is recorded, and the number is used as the number of abnormal points.

[0078] Step 403, determining whether the number of abnormal points is greater than a preset number, if so, an alarm is issued that the location of the abnormal data point is abnormal, and triggering a protection mechanism for the steam turbine.

[0079] In this embodiment, the number of abnormal points in all the detected points that have been counted is compared with the preset number. Optionally, the preset number can be set as a preset ratio of the total number of detected points. If the number of abnormal points is greater than the preset number, it means that the number of abnormal points is large and the steam turbine is operating abnormally. Then, an alarm is issued at the location where the abnormal data point is located to remind the administrator that the steam turbine is abnormal, and the protection mechanism of the steam turbine is automatically triggered. Specifically, the operation of the steam turbine can be automatically stopped, or the speed of the steam turbine can be controlled. Thus, the protection mechanism for the steam turbine is started to avoid more serious faults caused by the continuous operation of the steam turbine after the abnormal data appears.

[0080] Figure 5 The present invention is a flow chart of a protection mechanism for a steam turbine according to an embodiment of the present invention. Figure 5 Yes Figure 1 Step 102 and Figure 4 Specific instructions are given based on Figure 5 The embodiment shown comprises the following steps:

[0081] Step 501, controlling a relay module of a steam turbine to generate a switch instruction.

[0082] In this embodiment, after the abnormal data point is detected, the relay module controlling the steam turbine generates a set of switch signals as switch instructions. Specifically, the relay module can use A6500-RC to perform multiple logic operations such as "and", "or", "not", "exclusive or", "three out of two" on the detection data of any measurement module in the frame and send out a set of switch signals. Optionally, the relay module has 16 switch outputs.

[0083] Step 502, based on the switch command, start protection for the steam turbine.

[0084] According to the switch command generated by the relay module, the protection of the steam turbine can be started, and the whole or part of the modules of the steam turbine can be stopped, the speed can be reduced, etc. Thus, the protection mechanism of the steam turbine is implemented to avoid or reduce the damage to the steam turbine.

[0085] Figure 6 The present invention is a flow chart of a steam turbine TSI protection monitoring method according to an embodiment of the present invention. Figure 6 Yes Figure 1 Another illustration of the method, based on Figure 6 The embodiment shown comprises the following steps:

[0086] Step 601 , in response to a user control instruction, based on a multi-channel switch signal of a relay module of the steam turbine, a real-time online analysis of the working state of the steam turbine is performed.

[0087] In this embodiment, the relay module of the TSI system can receive user control instructions, respond to user operation instructions on the software side, convert the operation instructions into multi-way switch signals in the relay module of the turbine, and perform real-time analysis on the working status of the turbine.

[0088] Step 602 , in response to triggering a steam turbine protection mechanism, analyzing and recording system events of the steam turbine based on the operating status.

[0089] In this embodiment, when the protection mechanism of the steam turbine is triggered, the system events or fault causes of the steam turbine are analyzed and recorded according to the data of the working status of the steam turbine. Specifically, the real-time working status and system events can be viewed using the configuration software, which facilitates troubleshooting and greatly improves the reliability of monitoring and protection.
