Description

Technical Field

[0001] This application relates to the field of simulation testing technology, specifically to a simulation testing device for a gas turbine. Background Technology

[0002] Gas turbine-based generator sets, as core energy conversion devices, play a crucial role in industrial production and energy supply. Their stable operation directly impacts the efficiency and safety of the entire production system. The stable operation of a gas turbine relies on the precise control of its control system. The control system acts as the "nerve center" of the gas turbine, responsible for real-time monitoring of its operating parameters and adjusting its operating status to ensure optimal performance under various conditions. However, traditional methods for testing this "nerve center" have significant limitations. Traditional gas turbine control system testing often relies on physical gas turbines. While this method directly reflects the interaction between the control system and the gas turbine, it carries extremely high risks and costs: incorrect parameter settings or command execution deviations during testing can lead to malfunctions in the entire gas turbine, requiring substantial investment in repairs and causing production interruptions due to downtime, significantly reducing overall efficiency. To circumvent the drawbacks of physical testing, virtual simulation technology (i.e., the simulation device mentioned below) is used in some scenarios to simulate and test the control system. However, virtual simulation can only simulate the software logic and data interaction of the control system and cannot access the actual hardware level. In other words, it cannot simulate the actual response of the control system in scenarios such as loose or disconnected signal lines between the gas turbine and the control system (i.e., scenarios where information transmission is physically interrupted). Utility Model Content

[0003] The purpose of this application is to provide a simulation test device for a gas turbine to solve the technical problem that existing simulation devices cannot simulate the physical interruption of information transmission between the gas turbine and the control system.

[0006] The simulation device is electrically connected to the control system via various signal lines, and is configured to receive control signals from the control system, simulate various operating states of the gas turbine based on the control signals, generate corresponding status signals, and send the status signals to the control system.

[0014] As a specific embodiment of the technical solution in this application, the connector includes a hook with a flexible rope; or, the connector includes:

[0015] The connecting rod has a limiting groove at its end that opens toward the hook ring, and the minimum opening height of the limiting groove is greater than the thickness of the hook ring; the connecting rod also has a through hole that passes through the limiting groove, and the axis of the through hole is parallel to the axis of the hook ring.

[0016] A second driving member and a limiting post; the axis of the limiting post coincides with the axis of the through hole; the second driving member is disposed on the connecting rod; the second driving member is used to drive the limiting post to perform linear reciprocating motion along a second direction; the second direction is parallel to the axis of the through hole.

[0017] As a specific solution in this application, the opening height of the limiting groove increases along a first direction; the first direction is parallel to the insertion and removal direction of the signal line and points from the first end of the first driving member to the second end.

[0022] Compared with the prior art, the beneficial effects of this application are:

[0023] This application utilizes a wire-pulling device to disconnect any signal line between the control system and the simulation device, realistically simulating fault scenarios such as loose or detached signal lines. Traditional virtual simulations can only test software logic, while this device, by actively intervening in the hardware connection status, can verify the control system's response capability in the event of signal transmission interruption or anomalies (e.g., alarm logic and emergency control). This fills the gap in testing the stability and signal transmission accuracy of the control system's input and output modules, allowing the test results to more comprehensively reflect the control system's true performance. This application does not rely on a physical gas turbine; by simulating signal line faults, it can test the control system's fault tolerance capability, avoiding maintenance costs and downtime losses caused by real equipment failures. It also reduces the manpower required for manual wire pulling and lowers safety risks during the testing process. Attached Figure Description

[0034] Furthermore, it should be understood that, for ease of description, the dimensions of the various components shown in the accompanying drawings are not drawn to actual scale; for example, the thickness or width of some layers may be exaggerated relative to other layers.

[0035] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined or described in one figure, it will not need to be discussed or described in detail in the description of the subsequent figures.

[0036] To address the technical problem mentioned in the background art that existing simulation devices cannot simulate physical interruptions in information transmission between a gas turbine and its control system, this application proposes an embodiment of a gas turbine simulation testing device. This simulation testing device is applied to the control system 1 of a gas turbine, which includes multiple signal lines 11. In this embodiment, no restrictions are placed on the type of signal lines 11. For example, signal lines 11 can be analog signal lines (e.g., sensor signal lines or audio / video signal lines) or digital signal lines (e.g., Universal Serial Bus (USB) lines, High-Definition Multimedia Interface (HDMI) lines, network cables, or fiber optic cables).

[0037] In this embodiment, the simulation testing equipment includes a simulation device 2 and a wire disconnection device 3. The simulation device 2 is electrically connected to the control system 1 via various signal lines 11. That is, as... Figure 1 As shown, the control system 1 and the simulation device 2 can transmit data bidirectionally via various signal lines 11. Specifically, during the testing of the control system 1, the control system 1 can generate control commands (i.e., control signals in this embodiment) according to a preset program based on the gas turbine's status signals (in this embodiment, the status signals are simulated and generated by the simulation device 2). The gas turbine adjusts its operating state according to the control commands. Generally, the operating states of the gas turbine include: standby, cold run, guide vane inspection, cleaning, start-up light blowing, ignition and acceleration, idle and acceleration, synchronous idle, power generation, load increase / decrease, normal shutdown, and dual-fuel switching.

[0038] In this embodiment, the control system 1 can be the control system of any gas turbine that needs to be tested. For example, the control system 1 can be the control system corresponding to gas turbines such as AGT-15 and CGT40.

[0039] In this embodiment, the simulation device 2 is configured to receive control signals from the control system 1, simulate various operating states of the gas turbine based on the control signals, generate corresponding status signals, and send the status signals to the control system 1. Specifically, in this embodiment, there are no restrictions on the type and number of status signals. For example, the status signals can be any one or a combination of pressure signals, flow signals, temperature signals, current signals, and speed signals. Of course, the status signals can also be various signals simulated by the liquid fuel simulation module 21 to the instrumentation simulation module 29 mentioned below.

[0040] In this embodiment, the simulation device 2 can be any device capable of simulating various operating states of a gas turbine based on control signals. For example, the simulation device 2 can be the simulation system disclosed in the patent document with authorization number CN102306223B, entitled "Integrated Simulation System for Marine Gas Turbine Device Based on HLA Technology and its Implementation Method"; or, the simulation device 2 can be a system formed by the simulation method disclosed in the patent document with authorization number CN109858129B, entitled "A Dynamic Simulation Method for Gas Turbine in a Combined Heat and Power System"; or, the simulation device 2 can be the simulation device disclosed in the patent document with authorization number CN110147573B, entitled "A Simulation Method, Device and Storage Medium for a Gas Turbine". These will not be listed in detail here.

[0041] It is important to understand that in this embodiment, the control system 1 and the simulation device 2 transmit signals through multiple signal lines 11. This process relies on mature industrial signal transmission technology and requires no further explanation. The signal interaction logic between the two is clear: control signals issued by the control system 1 are transmitted to the simulation device 2 via signal lines 11, triggering it to simulate various operating states of the gas turbine; status signals generated by the simulation device 2 are also fed back to the control system 1 via signal lines 11, forming a closed-loop interaction. This type of signal transmission is based on existing industrial communication standards and can stably carry various signals such as control commands and parameter feedback. Its hardware interface adaptation, signal attenuation control, and anti-interference processing technologies are all mature and can meet the real-time and accurate signal transmission requirements between devices (i.e., between the control system 1 and the simulation device 2), so it will not be elaborated on further here.

[0042] In order to enable the simulation device 2 to accurately simulate the operating states of various auxiliary machines of the gas turbine (i.e., generate state signals of various auxiliary machines), thereby improving the realism of the simulation test of the control system 1, in one embodiment of this application, such as Figure 2 As shown, the simulation device 2 also includes any one or more of the following: liquid fuel simulation module 21, gaseous fuel simulation module 22, main engine lubricating oil simulation module 23, auxiliary engine lubricating oil simulation module 24, pressure oil simulation module 25, intake air filtration simulation module 26, generator simulation module 27, ventilation simulation module 28, and instrument air simulation module 29.

[0043] In this embodiment, various auxiliary machine simulation modules (i.e., liquid fuel simulation module 21 to instrumentation simulation module 29) can also establish corresponding auxiliary machine models based on the actual operating data of various auxiliary machines of the gas turbine. During subsequent simulation testing, corresponding auxiliary machine status signals are generated through these modules. For example, the status signals generated by the liquid fuel simulation module 21 may include any one or more combinations of information such as the flow rate, pressure, temperature, level, viscosity, and impurity content of the liquid fuel. This information is used to simulate key parameters of the gas turbine liquid fuel system under different operating conditions, providing state feedback related to the liquid fuel to the control system 1, and supporting the control system 1 in controlling and testing the liquid fuel supply and combustion process. The status signals generated by the gas fuel simulation module 22 may include any one or more combinations of information such as the flow rate, pressure, purity, humidity, composition, and calorific value of the gas fuel. This information is used to simulate the operating state of the gas fuel system, enabling the control system 1 to receive signals reflecting the characteristics and supply status of the gas fuel, thereby testing its ability to control gas fuel-related processes. The status signals generated by the main engine lubricating oil simulation module 23 may include any one or a combination of information such as the main engine lubricating oil level, oil temperature, oil pressure, contamination level, flow rate, and cooler outlet temperature. This information is used to simulate the working state of the main engine lubricating oil system, providing the control system 1 with lubricating oil system status data and assisting in testing the control system 1's regulation performance over the main engine lubrication and cooling. The status signals generated by the auxiliary engine lubricating oil simulation module 24 may include any one or a combination of information such as the auxiliary engine lubricating oil level, oil temperature, oil pressure, filtration differential pressure, circulation flow rate, and heater temperature. This information is used to simulate the operating state of the auxiliary engine lubricating oil system, providing the control system 1 with auxiliary engine lubrication-related status feedback and supporting the testing of the auxiliary engine lubricating oil system regulation logic. The status signals generated by the pressure oil simulation module 25 may include any one or a combination of information such as the pressure, flow rate, filtration status, main supply pipe pressure, and return oil temperature of the pressure oil. This information is used to simulate the working state of the pressure oil system, providing the control system 1 with pressure oil supply and circulation status data and assisting in testing the control system 1's regulation capability over pressure oil-related equipment. The status signals generated by the intake filtration simulation module 26 may include any one or a combination of several of the following: intake air cleanliness, flow rate, pressure, temperature, humidity, and filter differential pressure. This information is used to simulate the operating state of the intake filtration system, providing the control system 1 with signals of intake characteristics and filtration status to test its regulation performance over the gas turbine intake process. The status signals generated by the generator simulation module 27 may include any one or a combination of several of the following: generator output voltage, current, speed, power, frequency, power factor, and winding temperature. This information is used to simulate the generator's operating state, providing feedback on generator operating parameters to the control system 1 and supporting the testing of the generator's operation regulation logic.The status signals generated by the ventilation simulation module 28 may include any one or a combination of information such as ventilation volume, ventilation pressure, ventilation temperature, system resistance, outlet temperature, and fan speed. This information is used to simulate the operating state of the ventilation system, providing ventilation-related status data to the control system 1 and assisting in testing the control system 1's ability to regulate the gas turbine's heat dissipation and ventilation processes. The status signals generated by the instrument air simulation module 29 may include any one or a combination of information such as instrument air pressure, flow rate, dew point temperature, cleanliness, and tank pressure. This information is used to simulate the operating state of the instrument air system, providing the control system 1 with status feedback on instrument air supply and quality, and supporting the testing of the instrument air system's control logic.

[0044] To simulate the specific response of the control system 1 after the failure of signal line 11 (i.e., the unstable physical connection of the control system 1), and to cover the detection blind spot of the control system 1 so that the final test results can fully reflect the true performance of the control system 1, in one embodiment of this application, the simulation test equipment also needs to include a disconnection device 3. The disconnection device 3 is at least used to assist in disconnecting any signal line 11 between the control system 1 and the simulation device 2.

[0045] In this embodiment, the type of the wire-pulling device 3 is not limited. For example, the wire-pulling device 3 can be a rope or chain attached to the corresponding signal line 11, and the corresponding signal line 11 connecting the electrical control system 1 and the simulation device 2 can be pulled out by pulling the rope or chain. Or, as Figure 7 As shown, the wire pulling device 3 can be a hook ring 12 installed on the corresponding signal line 11. For gas turbine applications where signal lines are extremely dense, the corresponding signal line 11 can be quickly pulled out manually by hooking the corresponding hook ring 12 with a hook or other tool. In this embodiment, the rope, chain, or hook ring 12 can all be made of insulating material.

[0046] It should be noted that there are many lines in the control system 1. In order to avoid manual mis-disconnection of signal lines 11, labels can be set on the corresponding disconnection devices 3 (for example, a "liquid fuel" label (or other content) can be affixed to the signal line corresponding to the liquid fuel simulation module 21; a "gas fuel" label can be affixed to the signal line corresponding to the gas fuel simulation module 22, etc.).

[0047] The simulation testing equipment proposed in this embodiment can disconnect any signal line between the control system and the simulation device using a disconnection device, realistically simulating fault scenarios such as loose or detached signal lines. Traditional virtual simulations can only test software logic, while this device, by actively intervening in the hardware connection status, can verify the control system's response capability when signal transmission is interrupted or abnormal (e.g., alarm logic and emergency control), filling the gap in testing the stability and signal transmission accuracy of the control system's input and output module hardware, enabling the test results to more comprehensively reflect the control system's true performance. This simulation testing equipment does not rely on a physical gas turbine; it can test the control system's fault tolerance capability by simulating signal line faults, avoiding maintenance costs and downtime losses caused by real equipment failures, while also reducing the manpower required for manual disconnection and lowering safety risks during the testing process.

[0048] It is important to note that gas turbines operate in various states (e.g., standby, ignition and acceleration, load increase / decrease, and normal shutdown). Failure of signal line 11 under different states may trigger different system responses. Precisely controlling the timing of signal line 11 disconnection allows for the simulation of signal line loosening or detachment during specific operating phases (e.g., high-load operation or fuel switching). This verifies whether control system 1 can promptly identify signal anomalies, trigger alarm mechanisms, and execute emergency control logic (e.g., automatic load reduction or switching to a backup line) under these conditions, ensuring that test results accurately reflect the true performance of control system 1 under various possible fault scenarios. To precisely control the timing of signal line 11 anomalies (i.e., the timing of signal line 11 disconnection) during the simulation testing of control system 1, in one embodiment of this application, the disconnection device 3 further includes a disconnection bracket 31, a first driving component 32, and a connecting component 33. Specifically, as... Figure 3 As shown, the first end of the first driving member 32 is connected to the cable puller 31, and the second end is connected to the connector 33. The connector 33 can be engaged with the hook ring 12. Furthermore, the first driving member 32 can carry the connector 33 along a first direction (i.e., as shown in the diagram). Figure 3 The direction A) is shown to make a linear reciprocating motion, and the first direction is parallel to the insertion and removal direction of the signal line 11.

[0049] In use, first control the first driving component 32 along the first direction (i.e., as shown in the image) Figure 3 The connector 33 extends in direction A) to bring it close to the hook ring 12, thus hooking the connector 33 and the hook ring 12 together. Subsequently, when the simulation test needs to simulate signal line failure, the first drive unit 32 is controlled to shorten along the first direction (i.e., parallel to the insertion and removal direction of the signal line 11). Through the hook relationship between the connector 33 and the hook ring 12, the signal line 11 can be moved outward to realize the removal of the signal line 11.

[0050] In this embodiment, the first driving component 32 can be precisely initiated to pull the wire during a specific stage of the simulation test (e.g., during high-load simulation of a gas turbine or fuel switching) via a preset program or external control signal. The response delay is much lower than the human reaction time, which can strictly match the requirements of the test scenario for the timing of signal line failure. Furthermore, during the simulation test, there is no need for manual contact with live or densely packed lines, reducing the risk of electric shock, wire entanglement, etc., making it particularly suitable for long-term, high-frequency simulation test scenarios.

[0051] In the embodiments of this application, the main function of the cable puller 31 is to provide a stable mounting base and support for the first drive component 32. That is, in this embodiment, the shape and structure of the cable puller 31 are not limited, as long as it can provide a stable mounting base and support for the first drive component 32. For example, the cable puller 31 can be the housing of some equipment (e.g., the housing of the control system 1 or the housing of the simulation device 2); or, the cable puller 31 can be as follows: Figure 3 As shown, this is an L-shaped bracket that is easy to fix on the ground.

[0052] As mentioned above, the main function of the first driving member 32 is to drive the connecting member 33 to reciprocate along the first direction. In the embodiments of this application, no restrictions are placed on the first driving member 32 (the same applies to the second driving member 334 mentioned below, which will not be elaborated further), it is only necessary that the first driving member 32 can extend and shorten. For example, the first driving member 32 can be an electric actuator, a hydraulic actuator, or a linear motor, etc.

[0053] In this embodiment, there are no restrictions on the connector 33, as long as the connector 33 can be hooked with the hook ring 12. For example, the connector 33 can be as shown in Embodiment 1 and Embodiment 2 below.

[0054] Embodiment 1 of connector 33

[0055] In this embodiment, the connector 33 can be a hook with a flexible rope. Before the signal line 11 is pulled out, the hook can be manually attached to the hooking ring 12 on the corresponding signal line 11. In this embodiment, the flexible rope adapts to the hooking action through its own flexibility and provides sufficient tension to complete the wire pulling operation. Therefore, there are no restrictions on the type of flexible rope; for example, the flexible rope can be a rope or a chain. To avoid conductivity, the flexible rope can be a nylon rope or a polyester rope.

[0056] Embodiment 2 of connector 33

[0057] It should be noted that in Embodiment 1, the connector 33 (i.e., the hook) needs to be manually attached to the hook ring 12, which does not allow for automatic attachment of the connector 33 to the hook ring 12. In high-frequency, multi-signal-line testing scenarios, this increases manual operation costs and makes it difficult to achieve fully automated wire disconnection in conjunction with the first drive component 32. To enable the connector 33 to automatically attach to the hook ring 12, in this embodiment, the connector 33 may include a connecting rod 331, a second drive component 334, and a limiting post 335. Figure 7 As shown, the end of the connecting rod 331 is provided with a limiting groove 333 with its opening facing the hook ring 12, and the minimum opening height of the limiting groove 333 (e.g.) Figure 7 The height H shown is greater than the thickness of the hook ring 12 (e.g., Figure 7 (Thickness h shown). The connecting rod 331 is also provided with a through hole 332 penetrating the limiting groove 333, the axis of which is parallel to the axis of the hook ring 12. The axis of the limiting post 335 coincides with the axis of the through hole 332. A second driving member 334 is disposed on the connecting rod 331, and the second driving member 334 is used to drive the limiting post 335 to perform linear reciprocating motion along a second direction. The second direction is parallel to the axis of the through hole 332.

[0058] In use, first control the first driving component 32 along the first direction (i.e., as shown in the image). Figure 7 Elongation in direction A) as shown, so that the hook ring 12 is as Figure 7 The connecting rod 331 is inserted into the corresponding limiting groove 333 as shown. Then, the second driving member 334 is controlled to move in the second direction (i.e., as shown in the diagram). Figure 7 The connector 33 extends in direction B) so that the limiting post 335 passes through the hook ring 12. If the limiting post 335 passes through the hook ring 12, the connector 33 can form a stable connection with the hook ring 12. That is to say, this embodiment can achieve fully automatic connection between the connector 33 and the hook ring 12 through the connecting rod 331, the second driving member 334 and the limiting post 335, reducing manual operation and adapting to high-frequency, multi-signal-line testing scenarios.

[0059] It should be noted that in order for the mounting ring 12 to function as Figure 7 As shown, it successfully engages with the limiting slot 333. In the embodiments of this application, as... Figure 7 As shown, the opening height of the limiting groove 333 can increase along the first direction. The first direction (i.e., as shown) Figure 7 The direction A shown is parallel to the insertion / removal direction of the signal line 11, and points from the first end of the first drive member 32 to the second end.

[0060] In this embodiment, because the opening height of the limiting groove 333 increases along the first direction, a "gradually narrowing" guide channel can be formed. The hook ring 12 can first contact the side with the larger opening of the limiting groove 333. As the connecting rod 331 moves under the drive of the first driving member 32, the hook ring 12 gradually slides into the groove with a smaller opening height, and finally the hook ring 12 can accurately fit into the fitting position of the limiting groove 333. This design reduces the requirement for the initial alignment accuracy of the connecting rod 331 and the hook ring 12. Even if there is a slight positional deviation between the two, the inclined opening sidewall can guide the hook ring 12 smoothly into the limiting groove 333, ensuring the stability of the fully automatic hooking of the connector 33 and the hook ring 12. It is especially suitable for complex scenarios with dense signal lines and limited space.

[0061] This concludes the description of Embodiment 2 of connector 33.

[0062] It should be noted that in some application scenarios, it is necessary to unplug multiple signal lines 11 at once or in multiple steps. To enable the cable unplugging device 3 to unplug multiple signal lines 11 at once or in multiple steps, in this embodiment, the cable unplugging device 3 also includes a crossbar 34. For example... Figure 5 and Figure 6 As shown, the second end of the first driving member 32 is connected to the crossbar 34, and the crossbar 34 is provided with a plurality of connecting members 33.

[0063] In applications requiring the simultaneous removal of multiple signal lines 11, simply connect each connector 33 to the corresponding hook ring 12 on the signal line 11. In applications requiring the removal of multiple signal lines 11 in stages, the operation can be performed in stages by controlling the connection state of the corresponding connector 33 and hook ring 12 before each removal. For example, during the first removal, only the hook ring 12 of the signal line 11 to be removed first is connected to the corresponding connector 33, while the other connectors 33 remain separate from the hook ring 12. Then, the first drive unit 32 is controlled to shorten along the first direction, completing the removal of that group of signal lines 11. When the next removal is needed, the connection of the previous group of signal lines 11 is released, and the hook ring 12 of the next target signal line 11 is connected to the corresponding connector 33. The shortening action of the first drive unit 32 is repeated, thus completing the removal of multiple signal lines 11 in batches.

[0064] It should be noted that in application scenarios where multiple signal lines 11 need to be unplugged in multiple stages, if the connector 33 and the hanging ring 12 can be automatically hooked (for example, in Embodiment 2 above), different connectors 33 and corresponding hanging rings 12 can be sequentially hooked together through program presets or external control signals. For example, when unplugging the first line, only the connector 33 corresponding to the first group of target signal lines 11 is activated. After the hanging ring 12 is engaged in the limiting groove 333 of the connector 33, the second driving member 334 drives the limiting post 335 to pass through the hanging ring 12 to complete the locking. Then, the first driving member 32 is controlled to shorten along the first direction to realize the unplugging of this group of signal lines 11. After the unplugging action is completed, the second driving member 334 is controlled to drive the limiting post 335 to reset and release the hooking. Then, the connector 33 corresponding to the next group of target signal lines 11 is activated to repeat the above automatic hooking and unplugging action, thereby completing the unplugging of multiple signal lines 11 in batches. When the connector 33 is a flexible rope with a hook (i.e., Embodiment 1 above), the length of each flexible rope can be adjusted, and the signal lines 11 can be pulled out in batches by controlling the shortening distance of the first drive member 32 along the first direction. Specifically, for the signal line 11 that needs to be pulled out first, the length of its corresponding flexible rope can be set to be relatively short (e.g., 5 cm or 6 cm). When the first drive member 32 shortens to the corresponding distance, the hook connected to the flexible rope can pull the signal line 11 out. For the signal line 11 that is pulled out later, the length of its corresponding flexible rope can be set to be relatively long (e.g., 10 cm or 12 cm). In the initial stage of shortening of the first drive member 32, since the flexible rope is not taut, the hook will not move the signal line 11 until the first drive member 32 shortens to a longer distance and the flexible rope is taut. Only then will the corresponding signal line 11 be pulled out.

[0065] In this embodiment, the design of integrating multiple connectors 33 through the crossbar 34 can flexibly adapt to different pull-out requirements of multiple signal lines. It can simultaneously pull out multiple lines to simulate the extreme scenario of overall signal harness failure, or it can sequentially pull out single or partial signal lines through step-by-step control to simulate the working condition of connection failure of different signal lines. This allows for a more comprehensive test of the response logic and processing capability of the control system 1 under various line faults, further improving the realism and reliability of the simulation test.

[0066] To ensure the stability of the movement of the crossbar 34, in one embodiment of this application, the wire pulling device 3 further includes at least one slide rail 35, which is disposed in the control system 1 (e.g., Figure 4(As shown) or simulation device 2, and the slide rail 35 extends along the first direction. The crossbar 34 is provided with sliders 341 that correspond one-to-one with each slide rail 35. In use, the sliders 341 and the slide rails 35 can ensure that the crossbar 34 moves stably along the first direction. Especially in the scenario where multiple signal lines 11 are pulled out simultaneously or sequentially, it can ensure the consistency and accuracy of each pulling action, reduce signal line misoperation caused by mechanical shaking, and thus improve the reliability of the entire pulling device in simulation testing.

[0067] In order to enable real-time monitoring of the operating status and output control signals of control system 1, in one embodiment of this application, such as... Figure 1 As shown, the simulation test equipment may also include a first monitor 4, which is electrically connected to the control system 1. Through the first monitor 4, various control commands, parameter adjustment logic, and the system's own working status (e.g., whether it responds normally, whether there are any abnormal alarms, etc.) generated by the control system 1 after receiving the status signals fed back by the simulation device 2 can be directly obtained, providing data support for evaluating the software logic and hardware response performance of the control system 1.

[0068] In order to monitor the operation of simulation device 2 and the generated status signals in real time, in one embodiment of this application, such as... Figure 1 As shown, the simulation test equipment may also include a second monitor 5, which is electrically connected to the simulation device 2. The second monitor 5 can be used to view the accuracy and stability of the various operating states of the gas turbine simulated by the simulation device 2 based on the control signals of the control system 1 (e.g., the states of modules such as liquid fuel, gas fuel, and lubricating oil system), as well as the corresponding state signals (e.g., parameters such as pressure, flow rate, and temperature). This ensures that the simulation effect of the simulation device 2 meets the test requirements and provides a reliable simulation data source for verifying the feedback logic of the control system 1.

[0069] The simulation testing equipment proposed in this application can disconnect any signal line between the control system and the simulation device using a disconnection device, realistically simulating fault scenarios such as loose or detached signal lines. Traditional virtual simulations can only test software logic, while this device, by actively intervening in the hardware connection status, can verify the control system's response capability in the event of signal transmission interruptions or anomalies (e.g., alarm logic and emergency control), filling the gap in testing the stability and signal transmission accuracy of the control system's input and output modules. This allows the test results to more comprehensively reflect the true performance of the control system. This simulation testing equipment does not rely on a physical gas turbine; it can test the fault tolerance capability of the control system by simulating signal line faults, avoiding maintenance costs and downtime losses caused by real equipment failures. It also reduces the manpower required for manual disconnection and lowers safety risks during the testing process.

[0070] Although embodiments of this application have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of this application, the scope of which is defined by the appended claims and their equivalents.
