Description

Technical Field

[0001] The present invention relates to the technical field of coal yard interconnection in a coal-fired thermal power plant, and in particular to a coal yard interconnection control method and system. Background Art

[0002] Coal-fired power plants currently face some significant challenges in the operation of coal storage and transportation systems. Typically, the coal yard area of ​​a power plant is limited, resulting in insufficient coal reserves to support long-term power production needs, especially during peak periods such as the summer peak electricity consumption period, when coal is consumed very quickly, and the daily coal replenishment rate often cannot keep up with demand. In this case, the problem of insufficient coal reserves in the coal yard is particularly prominent. Once extreme weather such as typhoons or heavy rains, or if coal transportation equipment fails, the coal supply chain may be severely affected, threatening the safe operation of the power plant. Existing coal transportation systems usually rely on single-line transportation. The defect of this design is the lack of redundancy and the inability to provide a reliable backup path in the event of equipment failure or maintenance, which makes the system prone to paralysis at critical moments.

[0003] In addition, the flexibility and real-time dispatching capabilities of the traditional coal transportation system are also greatly insufficient during operation. When allocating coal between multiple coal yards, the existing technology cannot effectively integrate the resources of different coal yards, making it difficult to flexibly call and optimize the allocation of resources. This not only reduces the overall efficiency of the system, but also increases operational complexity and management costs. Especially in the case of constantly changing coal transportation and storage requirements, the existing system lacks dynamic control capabilities and cannot adjust the coal transportation route and coal distribution strategy according to real-time demand, resulting in low utilization of coal resources and affecting power generation efficiency. Summary of the invention

[0004] In view of the problems existing in the existing coal yard interconnection control and system, the present invention is proposed.

[0005] Therefore, the problem to be solved by the present invention is: through the construction of new interconnection facilities and optimization of control strategies, resource integration and flexible scheduling among multiple coal yards can be achieved, the coal storage capacity of the coal yard can be increased, the reliability of the coal transportation system can be improved, and real-time monitoring and adjustment can be carried out during the coal supply process with the help of dynamic control and intelligent coal blending algorithms.

[0006] In order to solve the above technical problems, the present invention provides the following technical solutions:

[0007] In a first aspect, an embodiment of the present invention provides a coal yard interconnection control method, which comprises the following steps:

[0008] Selecting a coal flow path from each coal supply point according to the coal flow state information and coal supply point information;

[0009] By using the interlocking automatic control algorithm, the interlocking devices are monitored in real time according to the real-time information of the coal flow path of each coal supply point, so as to optimize the coal flow path of each coal supply point;

[0010] According to the dynamic coal transportation management and control algorithm, the coal transportation process is monitored in real time, and automatic control is performed in the event of a failure to ensure the continuity of coal transportation;

[0011] Based on real-time monitoring of the coal transportation process, intelligent scheduling and coal blending algorithms are used to dynamically adjust the coal blending plan;

[0012] Based on the transportation process monitoring, real-time monitoring and optimization of the interlocking machine operation of each coal supply point can be achieved to achieve the optimal coal flow path selection;

[0013] In case of interlocking machine failure, intelligent interlocking operation management is used to achieve optimal coal flow path selection.

[0014] As a preferred solution of the coal yard interconnection control method of the present invention, the process of selecting the coal flow path from each coal supply point is as follows:

[0015] Based on the coal yard equipment data and coal transportation data, big data is used to calculate the mobility of each coal supply point and each coal route as the basis for selecting the coal flow path;

[0016] Select a coal flow path from the first coal supply point, and obtain the coal flow path and the state of the first coal supply point;

[0017] Get the status of each node on each coal transportation chain in the coal yard;

[0018] Starting from the selected coal supply point, select the connectable coal transportation path to the coal supply point, and determine whether this coal transportation path is connected. If no other connected path is selected, the coal is transported from the nearest coal transportation path by default, that is, the shortest line is used as the coal flow path;

[0019] If the coal supply point selects other paths, it is determined whether they are connected. If they are connected, the coal transportation path closest to the coal supply point is calculated as the selected path; otherwise, other paths are used to reach the connection point of the coal transportation point, and then the coal supply point is reached from the connection point via the shortest line, and the coal transportation path is selected as the selectable path of the coal transportation chain. At the same time, it is determined whether the path optimization conditions are met, and the path that meets the optimization conditions is marked as the preferred coal flow path;

[0020] Select the coal flow path from the remaining coal supply points according to the preferred path, judge the coal flow path of the next coal supply point, and select the coal flow path according to whether the current coal supply point has selected a suitable coal flow path;

[0021] If the coal flow path is not selected for the coal supply point, select the preferred coal flow path to the coal supply point;

[0022] If the coal flow path has been selected, determine whether the next coal supply point is connected and whether it is suitable for connection. If it is suitable for connection, compare the coal flow path selected for the coal supply point with that of the next coal supply point. After the comparison, mark the coal flow path that meets the optimization conditions as the preferred coal flow path; otherwise, re-judge; if there is no suitable path for all coal supply points, the end condition of the path selection is to reach the last coal supply point. At this time, the coal flow path selection ends, and the final selectable coal flow path is marked. The paths that meet the optimization conditions are marked as preferred coal flow paths.

[0023] As a preferred solution of the coal yard interconnection control method of the present invention, the process of monitoring the coal flow path of each coal supply point is as follows:

[0024] Use interlocking automatic control algorithm to monitor the coal flow path of each coal supply point, monitor the movement status and connectivity status of each coal flow in real time, and obtain the operating status information of each node equipment;

[0025] Obtain the location of each coal supply point and the location of the coal supply point connection node, visualize the location of each coal supply point and the equipment operation status information in the coal yard scene, monitor the interlocking status and movement trend of each equipment, analyze the working status of each path and each equipment according to the equipment operation status and path selection results, and monitor the operation status of each coal flow path;

[0026] The coal flow path information is stored in the database. Based on the coal flow path information, equipment association information and equipment status information, monitoring parameters are generated to judge the detection parameters and determine whether the connectivity status of each device has changed. If the device is connected, the coal movement status is detected in real time, and the working status data of each path and device is recorded and stored.

[0027] If the equipment fails or stops running, the equipment will be overhauled. After the equipment overhaul is completed, the coal flow path will be reselected.

[0028] As a preferred solution of the coal yard interconnection control method of the present invention, the real-time monitoring process of the transportation process is as follows:

[0029] Use dynamic coal handling management and control algorithms to achieve real-time monitoring of the transportation process. The monitoring process includes: monitoring the working conditions of each coal handling chain, monitoring the amount of coal on the equipment, monitoring the coal handling efficiency and monitoring process failures. Real-time parameters are obtained through sensors, signal devices and various instruments, and the measurement data is uploaded and summarized;

[0030] Convert real-time parameters into electrical signals, conduct logical judgment and control, promptly alarm in case of failure and timeout and control the coal conveyor chain to stop;

[0031] After the fault is successfully handled, the control is restarted to detect the amount of coal on the equipment. When the amount of coal on the equipment reaches the threshold, the coal conveying chain is controlled to run at a certain speed. By comparing the monitoring parameters with the set threshold, it is judged whether the equipment can run. If the threshold is reached, the equipment runs; if the threshold is not reached, the fault information is output; the coal conveying efficiency is monitored, and the speed is adjusted in real time during the coal conveying process to improve work efficiency; the fault parameters and monitoring parameters are stored, and the cause of the fault is analyzed through the historical records of the parameters to provide data support for fault warning and form coal yard operation and maintenance data.

[0032] As a preferred solution of the coal yard interconnection control method of the present invention, the intelligent dispatching coal blending process is as follows:

[0033] Use intelligent scheduling and coal blending algorithms to dynamically adjust the coal blending plan. According to the monitoring transportation path parameters, calculate the deviation between the current actual coal blending plan and the theoretical coal blending plan to obtain the parameter difference. When the deviation between the monitoring parameters and the theoretical coal blending plan exceeds the threshold, perform data correction, adjust the coal blending parameters, and recalculate the actual coal blending plan.

[0034] Adjust the coal blending plan in real time and update the real-time coal blending plan based on the latest actual coal blending situation;

[0035] According to the obtained parameter difference, the reliability of the coal blending plan is calculated; the real-time monitoring parameters and the calculated parameters are integrated, and the actual situation of the coal yard system is integrated into the coal blending result. While calculating the coal blending plan, the real-time monitoring parameter information is transmitted to the coal blending algorithm. After the coal blending plan is calculated, the real-time monitoring parameter information is integrated with the coal blending plan information to generate a real-time coal blending plan; the coal blending plan is optimized by the following optimization method: taking the calculated coal blending plan as the objective function and the monitoring parameters of the coal blending process as the constraints, the optimization goals and constraints are formulated to form an optimization model, and the optimal solution is found in the model solution space to complete the optimization of the coal blending plan; according to the real-time monitoring results, the coal blending plan is automatically configured and stored, and the dynamic coal blending plan realizes dynamic coal blending according to the changes in the real-time monitoring parameters.

[0036] As a preferred solution of the coal yard interconnection control method of the present invention, the process of realizing the optimal coal flow path selection is as follows:

[0037] Use interlocking management and operation optimization algorithms to monitor and optimize the interlocking machine operation of each coal supply point in real time, including: selecting the shortest time coal flow path for coal flow distribution, real-time monitoring and adjusting the parameters of each path, counting the coal volume and available capacity on each path, and calculating dangerous paths; monitoring whether the equipment is abnormal and counting the number of failures;

[0038] The real-time parameters of all paths are weighted and the best coal flow path is selected based on the processed data. The collected data is fused and compared with the data in the database. If there is a significant deviation from the data in the database, it is determined to be a dangerous state and the dangerous path data is uploaded to the cloud for processing and storage.

[0039] The monitoring data is fed back into the control algorithm to realize virtual-reality mapping and real-time display of coal flow paths. The coal flow parameters of each coal supply point, the operating status of each path and the equipment operating status are monitored, and the parameters of each coal supply point are displayed in real time in the coal yard scene.

[0040] As a preferred solution of the coal yard interconnection control method of the present invention, the intelligent interlocking operation management process is as follows:

[0041] Use intelligent interlocking operation management to achieve rapid processing and real-time monitoring of interlocking machine failures;

[0042] Upload each interconnection point and each interlocking machine information to the interlocking operation management platform, monitor the interlocking status in real time, and calculate the number of interlocking machine failures; receive interlocking machine abnormal information, formulate abnormal plans, feedback abnormal information, and automatically generate abnormal handling plans;

[0043] The monitoring data is integrated to extract abnormal information of the interlocking machine operation process and compare it with the real-time data. Through big data analysis, the operation risk of the interlocking machine is obtained, and real-time monitoring of the interlocking machine operation status and automatic repair of faults are achieved.

[0044] In a second aspect, an embodiment of the present invention provides a coal yard interconnection control system, which includes a collection module, an analysis module, and an output module;

[0045] The acquisition module is used to obtain coal flow status information and coal supply point information;

[0046] The analysis module is used to monitor each interlocking device in real time according to the real-time information of each coal supply and coal point flow path obtained, so as to optimize each coal supply and coal point flow path;

[0047] The output module is used to provide the optimal coal flow path selection.

[0061] Example 1

[0062] Reference Figure 1 to Figure 3 , which is the first embodiment of the present invention, and provides a coal yard interconnection control method, comprising the following steps:

[0063] S1. Select a coal flow path from each coal supply point based on the coal flow status information and coal supply point information.

[0064] The process of selecting the coal flow path from each coal supply point is:

[0065] Based on the coal yard equipment data and coal transportation data, big data is used to calculate the mobility of each coal supply point and each coal route as the basis for selecting the coal flow path;

[0066] Select a coal flow path from the first coal supply point, and obtain the coal flow path and the state of the first coal supply point;

[0067] Get the status of each node on each coal transportation chain in the coal yard;

[0068] Starting from the selected coal supply point, select the connectable coal transportation path to the coal supply point, and determine whether this coal transportation path is connected. If no other connected path is selected, the coal is transported from the nearest coal transportation path by default, that is, the shortest line is used as the coal flow path;

[0069] If the coal supply point selects other paths, it is determined whether they are connected. If they are connected, the coal transportation path closest to the coal supply point is calculated as the selected path; otherwise, other paths are used to reach the connection point of the coal transportation point, and then the coal supply point is reached from the connection point via the shortest line, and the coal transportation path is selected as the selectable path of the coal transportation chain. At the same time, it is determined whether the path optimization conditions are met, and the path that meets the optimization conditions is marked as the preferred coal flow path;

[0070] Select the coal flow path from the remaining coal supply points according to the preferred path, judge the coal flow path of the next coal supply point, and select the coal flow path according to whether the current coal supply point has selected a suitable coal flow path;

[0071] If the coal flow path is not selected for the coal supply point, select the preferred coal flow path to the coal supply point;

[0072] If the coal flow path has been selected, determine whether the next coal supply point is connected and whether it is suitable for connection. If it is suitable for connection, compare the coal flow path selected for the coal supply point with that of the next coal supply point. After the comparison, mark the coal flow path that meets the optimization conditions as the preferred coal flow path; otherwise, re-judge; if there is no suitable path for all coal supply points, the end condition of the path selection is to reach the last coal supply point. At this time, the coal flow path selection ends, and the final selectable coal flow path is marked. The paths that meet the optimization conditions are marked as preferred coal flow paths.

[0073] The process of monitoring the coal flow path of each coal supply point is as follows:

[0074] Use interlocking automatic control algorithm to monitor the coal flow path of each coal supply point, monitor the movement status and connectivity status of each coal flow in real time, and obtain the operating status information of each node equipment;

[0075] Obtain the location of each coal supply point and the location of the coal supply point connection node, visualize the location of each coal supply point and the equipment operation status information in the coal yard scene, monitor the interlocking status and movement trend of each equipment, analyze the working status of each path and each equipment according to the equipment operation status and path selection results, and monitor the operation status of each coal flow path;

[0076] The coal flow path information is stored in the database. Based on the coal flow path information, equipment association information and equipment status information, monitoring parameters are generated to judge the detection parameters and determine whether the connectivity status of each device has changed. If the device is connected, the coal movement status is detected in real time, and the working status data of each path and device is recorded and stored.

[0077] If the equipment fails or stops running, the equipment will be overhauled. After the equipment overhaul is completed, the coal flow path will be reselected.

[0078] S2. Utilize the interlocking automatic control algorithm to monitor each interlocking device in real time based on the real-time information of the coal flow path of each coal supply point, so as to optimize the coal flow path of each coal supply point.

[0079] S3. Based on the dynamic coal transportation management and control algorithm, the coal transportation process is monitored in real time, and automatic control is performed when a failure occurs to ensure the continuity of coal transportation.

[0080] The real-time monitoring process of the transportation process is as follows:

[0081] Use dynamic coal handling management and control algorithms to achieve real-time monitoring of the transportation process. The monitoring process includes: monitoring the working conditions of each coal handling chain, monitoring the amount of coal on the equipment, monitoring the coal handling efficiency and monitoring process failures. Real-time parameters are obtained through sensors, signal devices and various instruments, and the measurement data is uploaded and summarized;

[0082] Convert real-time parameters into electrical signals, conduct logical judgment and control, promptly alarm in case of failure and timeout and control the coal conveyor chain to stop;

[0083] After the fault is successfully handled, the control is restarted to detect the amount of coal on the equipment. When the amount of coal on the equipment reaches the threshold, the coal conveying chain is controlled to run at a certain speed. By comparing the monitoring parameters with the set threshold, it is judged whether the equipment can run. If the threshold is reached, the equipment runs; if the threshold is not reached, the fault information is output; the coal conveying efficiency is monitored, and the speed is adjusted in real time during the coal conveying process to improve work efficiency; the fault parameters and monitoring parameters are stored, and the cause of the fault is analyzed through the historical records of the parameters to provide data support for fault warning and form coal yard operation and maintenance data.

[0084] S4. Based on real-time monitoring of the coal transportation process, use intelligent scheduling and coal blending algorithms to dynamically adjust the coal blending plan.

[0085] The process of intelligent dispatching coal blending is:

[0086] Use intelligent scheduling and coal blending algorithms to dynamically adjust the coal blending plan. According to the monitoring transportation path parameters, calculate the deviation between the current actual coal blending plan and the theoretical coal blending plan to obtain the parameter difference. When the deviation between the monitoring parameters and the theoretical coal blending plan exceeds the threshold, perform data correction, adjust the coal blending parameters, and recalculate the actual coal blending plan.

[0087] Adjust the coal blending plan in real time and update the real-time coal blending plan based on the latest actual coal blending situation;

[0088] According to the obtained parameter difference, the reliability of the coal blending plan is calculated; the real-time monitoring parameters and the calculated parameters are integrated, and the actual situation of the coal yard system is integrated into the coal blending result. While calculating the coal blending plan, the real-time monitoring parameter information is transmitted to the coal blending algorithm. After the coal blending plan is calculated, the real-time monitoring parameter information is integrated with the coal blending plan information to generate a real-time coal blending plan; the coal blending plan is optimized by the following optimization method: taking the calculated coal blending plan as the objective function and the monitoring parameters of the coal blending process as the constraints, the optimization goals and constraints are formulated to form an optimization model, and the optimal solution is found in the model solution space to complete the optimization of the coal blending plan; according to the real-time monitoring results, the coal blending plan is automatically configured and stored, and the dynamic coal blending plan realizes dynamic coal blending according to the changes in the real-time monitoring parameters.

[0089] S5. Based on the monitoring of the transportation process, the interlocking machine operation of each coal supply point is monitored and optimized in real time to achieve the optimal coal flow path selection.

[0090] The process of achieving the optimal coal flow path selection is:

[0091] Use interlocking management and operation optimization algorithms to monitor and optimize the interlocking machine operation of each coal supply point in real time, including: selecting the shortest time coal flow path for coal flow distribution, real-time monitoring and adjusting the parameters of each path, counting the coal volume and available capacity on each path, and calculating dangerous paths; monitoring whether the equipment is abnormal and counting the number of failures;

[0092] The real-time parameters of all paths are weighted and the best coal flow path is selected based on the processed data. The collected data is fused and compared with the data in the database. If there is a significant deviation from the data in the database, it is determined to be a dangerous state and the dangerous path data is uploaded to the cloud for processing and storage.

[0093] The monitoring data is fed back into the control algorithm to realize virtual-reality mapping and real-time display of coal flow paths. The coal flow parameters of each coal supply point, the operating status of each path and the equipment operating status are monitored, and the parameters of each coal supply point are displayed in real time in the coal yard scene.

[0094] S6. In case of interlocking machine failure, intelligent interlocking operation management is used to retrieve relevant equipment data from the coal yard equipment module library. Digital twin technology based on the cloud platform is used to establish a digital twin of the coal yard scene to achieve virtual-reality mapping. Twin visualization technology is used to visually monitor the execution process of the control algorithm.

[0095] The intelligent interlocking operation management process is:

[0096] Use intelligent interlocking operation management to achieve rapid processing and real-time monitoring of interlocking machine failures;

[0097] Upload each interconnection point and each interlocking machine information to the interlocking operation management platform, monitor the interlocking status in real time, and calculate the number of interlocking machine failures; receive interlocking machine abnormal information, formulate abnormal plans, feedback abnormal information, and automatically generate abnormal handling plans;

[0098] The monitoring data is integrated to extract abnormal information of the interlocking machine operation process and compare it with the real-time data. Through big data analysis, the operation risk of the interlocking machine is obtained, and real-time monitoring of the interlocking machine operation status and automatic repair of faults are achieved.

[0099] This transformation connects to the cantilever position signal of #1 bucket wheel excavator and the tail car reclaiming position signal.

[0100] When the coal is piled via the C3 belt, Figure 1 When the process No. 3 is C3 Huatong coal stacking, the arm position of #1 bucket wheel machine is on the Huatong side, and the pre-start position is valid. When the working mode is interlocked automatic, the pre-start is valid and the C3 coal stacking process can be started. If the arm position of #1 bucket wheel machine is on the Sutong side during the coal stacking process, the C3 belt will trigger a joint trip. Similarly, when selecting Figure 1 During the process of No. 4, when the C3 Sutong coal stacking is carried out, the arm position of the #1 bucket wheel machine is on the Sutong side, and the pre-start position is valid. When the working mode is interlocked automatic, the pre-start is valid and the C3 coal stacking process can be started. If the arm position of the #1 bucket wheel machine is on the Huatong side during the coal stacking process, the C3 belt will trigger the joint jump.

[0101] When the coal is taken from the C3 belt, Figure 1 When the process No. 9 or 10 is C3 Huatong coal extraction, the arm position of #1 bucket wheel machine is on the Huatong side, and the pre-start position is valid. When the working mode is interlocked automatic, the pre-start is valid and the C8A / B process can be started. If the arm position of #1 bucket wheel machine is on the Sutong side during coal extraction, the C3 belt will trigger a joint trip. Similarly, when selecting Figure 1During the process No. 11, when the C3 Sutong coal is taken, the arm position of the #1 bucket wheel machine is on the Sutong side, and the pre-start position is valid. When the working mode is interlocked automatic, the pre-start is valid and the C18A / B process can be started. If the arm position of the #1 bucket wheel machine is on the Huatong side during the coal stacking process, the C3 belt will trigger a joint jump.

[0102] When entering the warehouse directly, select Figure 1 During the process No. 6, the tail car of #1 bucket wheel excavator should be in the material taking position, and the pre-start position is valid. When the working mode is interlock automatic, the C18A / B process can be started only when the pre-start is valid.

[0103] The Huatong Plant process and the Sutong Plant process after transformation in this embodiment are as follows: Figure 2 and Figure 3 As shown,

[0104] At the C16A / B belt of Sutong Plant, there can be at most two coal flows for blending, and when blending, one coal flow stops and the other coal flow jumps. For example, when the C19 belt and the C15A belt are blending and feeding coal to C16A, if C19 stops, C15A will trigger a jump.

[0105] The process selection follows the previous rules from back to front. For example, first select the C16A / B belt, and then select the C19 belt. In the process selection diagram of the Sutong Factory, the #19 belt process must be selected before the Huatong Factory can continue to select the process. The connection lines between the Huatong Factory equipment A activation, #2A belt, C3 Sutong material reclaiming, and C3 Sutong direct button are only used for status display. Similarly, in the process selection diagram of the Huatong Factory, the #19 belt process of the Sutong Factory must be selected before the Huatong Factory can continue to select the process. The #19 belt of the Huatong Factory is only used for status display

[0106] In summary, by realizing the interconnection and resource integration of multiple coal yards, the coal storage capacity of the coal yards has been effectively improved, especially during peak demand periods, which can better guarantee the coal supply of power plants and reduce the risk of downtime caused by insufficient coal storage; the intelligent scheduling and coal blending algorithm can dynamically adjust the coal blending plan according to actual demand and coal quality, improve the utilization rate of coal resources, reduce resource waste and reduce operating costs; it also has real-time monitoring and dynamic adjustment capabilities, can promptly discover and deal with problems in the coal transportation process, ensure the stable operation of the coal transportation system under various complex working conditions, and ultimately improve the flexibility and reliability of the overall supply chain of the power plant.
