Description

Technical Field

[0001] The present invention relates to the technical field of steam turbines, and in particular to a steam turbine energy-saving and efficiency-enhancing device capable of adaptively adjusting operating conditions. Background Art

[0002] Steam turbines, as core energy conversion equipment, are widely used in power generation, industrial drives, and marine propulsion. Their operating efficiency directly impacts energy utilization and system economics. In actual operation, steam turbines often face variable operating conditions such as load fluctuations, steam parameter variations, and grid frequency adjustments. Traditional control systems rely on fixed control strategies or PID algorithms based on steady-state design, adjusting inlet valve opening, steam extraction rate, and other factors through manually preset parameters.

[0003] Although existing technologies have attempted to optimize strategies by adding sensors or introducing intelligent algorithms, they still have shortcomings: the detection module covers limited parameters, lacks multi-dimensional data collection such as speed, load, and blade stress, and the control model input information is incomplete; the control module and the actuator lack coordination, and the adjustment instructions are limited to a single unit. There is a lack of coordinated adjustment of the steam inlet volume, exhaust back pressure, and blade aerodynamic characteristics, making it difficult to achieve global optimization of energy flow; the system has weak adaptive capabilities and relies on manual offline calibration strategies. It is unable to dynamically update control rules based on real-time data and has difficulty coping with complex working conditions. The above problems cause traditional devices to respond slowly and waste significant energy when adjusting variable loads. There is an urgent need for a control device with real-time working condition perception, multi-parameter coupling analysis, and self-learning capabilities. Summary of the Invention

[0004] In order to solve the above problems, the present invention proposes a steam turbine energy-saving and efficiency-enhancing device that can adapt to complex working conditions by using multiple modules to work together and dynamically update control rules based on real-time data.

[0005] To solve the above technical problems, the present invention proposes a technical solution: a steam turbine energy-saving and efficiency-enhancing device with adaptive variable operating condition adjustment, comprising:

[0006] Detection module, used to collect turbine operating parameters in real time;

[0007] The control module is electrically connected to the detection module and has a built-in variable operating condition adjustment strategy library, which matches the corresponding adjustment strategy based on the operating condition parameters and generates a control signal;

[0008] The execution module is electrically connected to the control module and includes a steam inlet adjustment unit, an exhaust adjustment unit and a blade speed adjustment unit, and is used to adjust the turbine operating parameters according to the control signal.

[0009] Furthermore, the detection module includes a pressure sensor 1 and a temperature sensor 1 arranged on the steam inlet pipe; a pressure sensor 2 and a temperature sensor 2 arranged on the exhaust pipe; and a speed sensor and a load detection component arranged on the rotating shaft.

[0010] Furthermore, the control module includes: a data processing unit, which is used to filter, reduce noise and perform analog-to-digital conversion on the collected operating parameters; a strategy matching unit, which pre-stores adjustment rules and target parameters for multiple operating intervals, and is used to match the optimal adjustment strategy according to the real-time operating parameters; a signal generation unit, which calculates the adjustment amount based on the matched adjustment strategy and outputs a control signal.

[0011] Furthermore, the optimal regulation strategy is generated by analyzing historical operating data such as turbine efficiency, energy consumption and power output.

[0012] Furthermore, the steam inlet regulating unit and the exhaust regulating unit are pneumatic regulating valves, and the blade speed regulating unit includes a servo motor and a transmission component, and the servo motor is connected to the turbine blades through the transmission component.

[0013] Furthermore, it also includes a human-computer interaction module, which is electrically connected to the control module and is used to input preset parameters and display real-time working conditions and operating status.

[0014] Furthermore, the human-computer interaction module includes a touch screen and a parameter input interface, and the screen displays the detection parameters, the adjustment strategy matching status and the execution module action feedback in real time.

[0015] Furthermore, the control module integrates a fault diagnosis unit, which performs fault diagnosis by monitoring abnormal fluctuations in operating parameters and response delays of the execution module, and triggers alarm and protection mechanisms.

[0016] Compared with the existing technology, the advantages of the present invention are: the detection module collects key parameters such as steam inlet, exhaust, shaft speed and load in real time, providing an accurate data basis for the system; the control module processes and analyzes these data, matches the optimal adjustment plan in combination with the built-in strategy library, and generates a control signal; the execution module responds quickly and accurately adjusts operating parameters such as steam inlet, exhaust and blade speed. When faced with complex working conditions, the device dynamically updates the control rules based on real-time data. The control module optimizes the adjustment strategy by analyzing the historical operating data of the steam turbine, taking into account multiple factors such as efficiency and energy consumption. At the same time, the fault diagnosis unit detects anomalies in a timely manner, and the human-computer interaction module facilitates manual intervention. The modules work closely together to ensure that the steam turbine can maintain efficient and energy-saving operation under different working conditions, fully demonstrating strong adaptability and reliability.

[0024] Combined with attachment Figure 1 , Attachment Figure 2 The control module is electrically connected to the detection module and has a built-in variable operating condition adjustment strategy library. It matches the corresponding adjustment strategy based on the operating condition parameters and generates a control signal. The control module includes: a data processing unit 10, which is used to filter and reduce noise and perform analog-to-digital conversion on the collected operating condition parameters to improve data accuracy; a strategy matching unit 11, which pre-stores adjustment rules and target parameters for multiple operating condition intervals and is used to match the optimal adjustment strategy based on real-time operating condition parameters; a signal generation unit 12, which calculates the adjustment amount based on the matched adjustment strategy and outputs a control signal to achieve precise adjustment. The optimal adjustment strategy is generated by analyzing historical operating data such as steam turbine efficiency, energy consumption, and power output, fully considering factors such as steam turbine efficiency, energy consumption, and power output to improve energy saving and efficiency.

[0025] Combined with attachment Figure 1 , Attachment Figure 2 , Attachment Figure 3The execution module, electrically connected to the control module, includes a steam inlet regulating unit 1, an exhaust regulating unit 2, and a blade speed regulating unit 3, which are used to adjust turbine operating parameters based on the control signal. The steam inlet regulating unit 1 and the exhaust regulating unit 2 are pneumatic control valves with rapid response and high adjustment accuracy. The blade speed regulating unit 3 includes a servo motor and a transmission component. The servo motor is connected to the turbine blades via the transmission component, enabling precise control of the blade speed.

[0026] Combined with attachment Figure 1 , Attachment Figure 2 The control module integrates a fault diagnosis unit 14, which performs fault diagnosis by monitoring abnormal fluctuations in operating parameters and response delays of the execution module, and triggers alarm and protection mechanisms, thereby timely discovering potential problems, avoiding equipment damage, and improving the safety of device operation.

[0027] Combined with attachment Figure 1 , Attachment Figure 2 , Attachment Figure 4 The system also includes a human-machine interface module 13, which is electrically connected to the control module and is used to input preset parameters and display real-time working conditions and operating status, facilitating operator monitoring and intervention.

The touch screen can intuitively display the equipment's operating status, and the parameter input interface allows operators to adjust preset parameters according to actual needs, enhancing the device's adaptability.

[0028] In a specific embodiment of the present invention, the detection module first starts operating. Pressure sensor 1 (4) and temperature sensor 1 (5) in the steam inlet pipe monitor the steam inlet status in real time. Pressure sensor 2 (6) and temperature sensor 2 (7) in the exhaust pipe provide feedback on the exhaust status. A speed sensor 8 and a load detector 9 on the shaft monitor the shaft's operating status and transmit the collected operating parameters to the control module. A data processing unit 10 filters and reduces noise and performs analog-to-digital conversion on the parameters. A strategy matching unit 11 matches the optimal control strategy from a library of variable operating condition control strategies based on the processed data. A signal generation unit 12 calculates the control variable based on the strategy and outputs a control signal. Upon receiving the control signal, the execution module coordinates the pneumatic control valves of the steam inlet control unit 1 and the exhaust control unit 2, and the servo motor and transmission components of the blade speed control unit 3 to adjust the turbine operating parameters. Simultaneously, the touchscreen display of the human-machine interface module 13 displays the operating conditions, strategy matching, and execution status in real time. The operator can adjust preset parameters through the parameter input interface. If the fault diagnosis unit 14 detects an abnormal operating condition or execution delay, it immediately triggers an alarm and protection mechanism to ensure safe operation of the device.
