Description

Technical Field

[0002] In the field of thermal power generation, deep peak load regulation has become an important operational requirement. Deep peak load regulation requires the unit to maintain stable operation at a lower load and quickly respond to the load demand of the power grid. However, the traditional boiler-steam turbine load generation circuit often adopts a rigid connection method, which is difficult to adapt to the changes in boiler combustion characteristics and the rapid adjustment requirements of steam turbine load under deep peak load regulation conditions.

[0042] The following is a description of exemplary embodiments of the present disclosure in conjunction with the accompanying drawings, including various details of the embodiments of the present disclosure to facilitate understanding, which should be considered as merely exemplary. Therefore, it should be recognized by those of ordinary skill in the art that various changes and modifications may be made to the embodiments described herein without departing from the scope and spirit of the present disclosure. Similarly, for the sake of clarity and conciseness, descriptions of well-known functions and structures are omitted in the following description.

[0043] The method and device for generating power from a steam turbine, an electronic device, and a storage medium according to an embodiment of the present disclosure will be described below with reference to the accompanying drawings.

[0044] Figure 1 A schematic flow chart of a method for generating steam turbine power provided in an embodiment of the present disclosure.

[0045] like Figure 1 As shown, the method comprises the following steps:

[0046] Step 101 , monitoring the main steam pressure of the boiler and the steam pressure at the turbine inlet of the steam turbine, and calculating the pressure deviation between the boiler and the steam turbine.

[0047] In an embodiment of the present disclosure, in order to ensure the efficient and stable operation of the boiler and steam turbine system during the industrial production process, it is necessary to monitor the main steam pressure of the boiler and the steam pressure at the inlet of the steam turbine in real time. The steam pressure data of these two key points can be obtained through a high-precision pressure sensor or pressure gauge. Subsequently, further calculations can be performed using these data to determine the deviation between the main steam pressure generated by the boiler and the steam pressure received at the inlet of the steam turbine. The calculation of this pressure deviation is crucial for timely discovery and resolution of possible pressure mismatch problems in the system, and helps maintain the stability and safety of the entire steam power system, thereby optimizing the production process and improving energy efficiency.

[0048] Step 102, when the pressure deviation exceeds the deviation threshold, calling a dynamic adjustment algorithm to calculate the load change rate adjustment amount of the steam turbine.

[0049] In an embodiment of the present disclosure, in an industrial production or energy conversion process, when it is monitored that the deviation between the main steam pressure of the boiler and the steam pressure at the inlet of the steam turbine exceeds a preset deviation threshold, this generally means that the system operating state may deviate from the optimal or safe operating range. In order to respond to this situation quickly and effectively, the system will automatically trigger a dynamic adjustment mechanism. The core of this mechanism is an advanced dynamic adjustment algorithm that can perform fast and accurate calculations based on the current pressure deviation size, direction, and other relevant parameters of the system (such as temperature, flow, etc.). The task of the dynamic adjustment algorithm is to calculate the adjustment amount of the steam turbine load change rate, which is necessary to guide the system back to the set normal operating state or safe range. The algorithm will comprehensively consider multiple factors, including but not limited to the inertia of the system, the response time, and the interaction between the steam turbine and the boiler to ensure the accuracy and effectiveness of the adjustment measures.

[0050] By implementing this adjustment, the load change rate of the steam turbine will be adjusted accordingly, which will help reduce or eliminate pressure deviation and achieve a better match between the steam pressure generated by the boiler and the steam pressure required by the steam turbine. This will not only help improve the stability and efficiency of the entire steam power system, but also effectively avoid equipment damage or production accidents that may be caused by pressure mismatch, ensuring the safety and continuity of industrial production.

[0051] Step 103: generating a power regulation rate of the steam turbine based on the load change rate adjustment amount, and adjusting the steam turbine power of the steam turbine according to the power regulation rate.

[0052] In the embodiments of the present disclosure, in a complex system of industrial production or energy conversion, once the adjustment amount of the turbine load change rate is calculated by a dynamic adjustment algorithm, it is necessary to convert this adjustment amount into a specific operating instruction to achieve precise control of the turbine power. This step involves generating the power adjustment rate of the turbine according to the adjustment amount of the load change rate, which is a key process for converting theoretical calculation results into actual operating parameters. In short, the power adjustment rate is the speed and amplitude of the turbine power adjustment, which directly determines the ability of the turbine to respond to load changes. When generating this adjustment rate, the system will comprehensively consider a variety of factors, including the physical characteristics of the turbine (such as rotor inertia, thermal efficiency, etc.), the current operating state (such as load size, speed, etc.), and the system's requirements for response speed. Through a complex calculation model, the system can accurately convert the adjustment amount of the load change rate into instructions on how the turbine power should change quickly and smoothly.

[0053] Once the power adjustment rate is determined, the system will immediately adjust the turbine power of the steam turbine according to this rate. This usually involves a series of precise instructions to the steam turbine control system, including adjusting the fuel supply, changing the intake valve opening, adjusting the cooling system, etc., to ensure that the steam turbine can smoothly increase or decrease power output according to the predetermined power adjustment rate. Such an adjustment process requires not only fast response, but also high stability and accuracy to ensure that the entire steam power system can maintain efficient and safe operation under various operating conditions.

[0054] In this way, the system can achieve fine control of steam turbine power, thereby effectively responding to load changes, maintaining pressure balance between boiler and steam turbine, optimizing energy utilization, improving production efficiency, and ensuring the stability and safety of the entire industrial production process.

[0055] The present disclosure provides a method for generating power of a steam turbine, which monitors the main steam pressure of a boiler and the steam pressure at the steam turbine inlet, and calculates the pressure deviation between the boiler and the steam turbine; when the pressure deviation exceeds a deviation threshold, calls a dynamic adjustment algorithm to calculate the load change rate adjustment amount of the steam turbine; based on the load change rate adjustment amount, generates the power adjustment rate of the steam turbine, and adjusts the steam turbine power of the steam turbine according to the power adjustment rate. Compared with the related art, the embodiment of the present disclosure can quickly calculate and adjust the load change rate of the steam turbine according to the pressure deviation by real-time monitoring the pressure deviation between the main steam pressure and the steam pressure at the steam turbine inlet, which helps to maintain the stability of the unit load and prevent system instability caused by large load fluctuations; by accurately controlling the power of the steam turbine, it can ensure that the steam generated by the boiler is fully utilized, reduce energy waste, and improve overall energy utilization efficiency.

[0056] As an achievable manner of the embodiment of the present disclosure, the method further includes: determining an adjustment range and an adjustment step of the load change rate of the steam turbine based on the monitoring result of the pressure deviation.

[0057] Specifically, in industrial production or energy conversion systems, real-time monitoring of the deviation between the boiler main steam pressure and the turbine inlet steam pressure is a key link to ensure stable system operation and efficient energy utilization. Based on these monitoring results, the system can further analyze and determine the adjustment range and adjustment step of the turbine load change rate.

[0058] The system will determine the adjustment range of the turbine load change rate based on the size and direction of the pressure deviation and the preset safe operation parameters. This range is usually set within a reasonable range that can quickly respond to pressure deviations without causing excessive impact on the system. If the pressure deviation is large, it means that there is a large gap between the current state of the system and the ideal state. At this time, the adjustment range may be expanded accordingly to speed up the system to restore balance; conversely, if the pressure deviation is small, the adjustment range may be appropriately reduced to ensure the fineness and stability of the adjustment.

[0059] Next, the system will further refine the adjustment step size within the determined adjustment range according to the actual operating conditions and the physical characteristics of the turbine. The adjustment step size refers to the specific value used each time the turbine load change rate is adjusted, which directly affects the smoothness and accuracy of the adjustment process. The system will select an appropriate step size that can effectively reduce pressure deviation without causing system oscillation or overshoot based on a comprehensive evaluation of the turbine's response speed, control accuracy, and current operating status.

[0060] By determining the adjustment range and adjustment step, the system can achieve precise control of the turbine load change rate, thereby ensuring that the pressure deviation between the boiler and the turbine is corrected in a timely and effective manner. This not only helps to improve the stability and efficiency of the entire steam power system, but also effectively extends the life of the equipment, reduces maintenance costs, and provides a strong guarantee for the continuous and efficient operation of industrial production.

[0061] Furthermore, in a possible implementation of this embodiment, the calling of the dynamic adjustment algorithm to calculate the load change rate adjustment amount of the steam turbine includes:

[0062] Acquiring operating status data of the boiler and the steam turbine;

[0063] The load change rate adjustment amount of the steam turbine is calculated according to the operating status data and the size and direction of the pressure deviation.

[0064] Specifically, in order to quickly and accurately adjust the load change rate of the steam turbine, the system will call an efficient dynamic adjustment algorithm. The execution process of this algorithm involves multiple key steps, the core of which includes obtaining the operating status data of the boiler and steam turbine, and calculating the load change rate adjustment of the steam turbine based on these data and specific information of the pressure deviation.

[0065] First, the system needs to obtain comprehensive and real-time data on the operating status of the boiler and steam turbine. These data cover the boiler's combustion efficiency, steam generation, steam temperature, and the turbine's speed, load, air intake, exhaust temperature and other key parameters. These data are the basis for the dynamic adjustment algorithm to perform precise calculations. They provide a comprehensive view of the system's current operating status, allowing the algorithm to accurately evaluate the impact of pressure deviations on the overall system performance.

[0066] Next, the dynamic adjustment algorithm will perform a series of complex calculations and analyses based on the acquired operating status data, as well as the size and direction of the monitored pressure deviation. The algorithm will consider the interaction between the boiler and the steam turbine, as well as the system's response characteristics to load changes, to evaluate the effect of different load change rate adjustments on the correction of system pressure deviations. In this process, the algorithm may use advanced mathematical models and optimization algorithms, such as linear programming, nonlinear control theory, or machine learning algorithms, to ensure the accuracy and reliability of the calculation results.

[0067] Finally, based on these calculations and analyses, the dynamic regulation algorithm will output a specific turbine load change rate adjustment. This adjustment is determined based on the current state of the system, the actual pressure deviation, and the optimization goal. It can guide the turbine control system to adjust the load change rate in the most appropriate way, thereby quickly and smoothly correcting the pressure deviation, ensuring the pressure balance between the boiler and the turbine, and improving the stability and efficiency of the entire steam power system.

[0068] Further, in a possible implementation of this embodiment, generating a power regulation rate of the steam turbine based on the load change rate adjustment amount, and adjusting the steam turbine power of the steam turbine according to the power regulation rate includes:

[0069] Converting the calculated load change rate adjustment amount into a control instruction, and outputting it to a steam turbine control system to adjust the load change rate of the steam turbine;

[0070] Based on the mapping relationship between the load change rate and the power regulation rate, the power regulation rate of the steam turbine is determined, and the steam turbine power of the steam turbine is adjusted according to the power regulation rate.

[0071] Specifically, the system converts the calculated load change rate adjustment into specific control instructions. This conversion process needs to take into account the characteristics and requirements of the turbine control system to ensure the accuracy and executability of the instructions. After the conversion is completed, these control instructions will be output to the turbine control system in real time. These instructions usually include adjusting the fuel supply, changing the opening of the intake or exhaust valve, adjusting the flow of the cooling system, etc., to directly affect the operating state and load change rate of the turbine. By accurately controlling these parameters, the system can guide the turbine to adjust according to the predetermined load change rate, thereby effectively responding to pressure deviations. Next, the system will determine the power adjustment rate of the turbine based on the mapping relationship between the load change rate and the power adjustment rate. This mapping relationship is established based on the physical characteristics of the turbine, the response characteristics of the control system, and the system's demand for power adjustment. It ensures the coordination between the load change rate and the power adjustment rate, so that the turbine can maintain a stable power output when adjusting the load. Once the power adjustment rate is determined, the system will adjust the turbine power of the turbine according to this rate. This typically involves continuous monitoring and adjustment of the turbine control system to ensure that power changes match the rate of load changes, thereby maintaining stable operation of the entire system.

[0072] During this process, the system also needs to continuously monitor the operating status of the boiler and steam turbine, as well as the pressure deviation between them. This helps the system to timely evaluate the adjustment effect and fine-tune the control instructions and power adjustment rate according to the actual situation. Through such a closed-loop control strategy, the system can achieve fine adjustment of steam turbine power, ensure that the pressure balance between the boiler and the steam turbine is continuously maintained, and provide strong guarantee for the continuous, efficient and safe operation of industrial production.

[0073] It should be noted that the embodiments of the present disclosure may include multiple steps. For the convenience of description, these steps are numbered, but these numbers do not limit the execution time slots or execution order between the steps; these steps can be implemented in any order, and the embodiments of the present disclosure do not limit this.
