Description

TECHNICAL FIELD

[0001] The application provides a running management method, in particular, an intelligent running management method for an unattended hydropower station, and belongs to the technical field of automatic management. BACKGROUND

[0002] With the continuous development of the power system in China and the continuous progress of power production related technologies, the automation degree and safe operation level of hydropower generation are continuously improved, and the operation on-duty mode of hydropower stations begins to gradually develop from "few people on duty" to "unattended". For the cascade hydropower stations in a river basin, in the unattended operation and management mode, the control center is the off-site on-duty unit of the hydropower station, responsible for the remote monitoring of the unattended hydropower stations in the river basin, and the on-site of the hydropower station no longer monitors and shifts on duty all day long. At present, the main problems existing in the daily management method of the unattended cascade hydropower stations in a river basin are: 1) the daily work of the unattended hydropower stations in a river basin is managed by each hydropower station, and due to the close water and electricity linkage relationship between the hydropower stations in a river basin, if the information communication between the hydropower stations and the control center is not smooth, the work efficiency will be affected, and the safety risk of equipment will be increased; 2) the unattended hydropower stations in a river basin communicate information with the control center through telephone, and with the continuous access of unattended hydropower stations, the on-duty work of the control center is continuously increased, and when the business is more, such telephone will interrupt the normal processing thought of the control on-duty personnel, and the work efficiency is reduced; 3) the management of the unattended cascade hydropower stations in a river basin is not high in intelligent level, and excessively relies on artificial decision, the personnel level has great influence on the management level, and there is no efficient analysis and processing method for the daily work management record data of each hydropower station, which is not conducive to the improvement and deepening of the management level. Therefore, it is necessary to improve the existing technology. SUMMARY

[0003] In order to solve the many problems and disadvantages existing in the daily management method of the existing unattended cascade hydropower stations in a river basin, the application provides an intelligent running management method for a hydropower station based on an unattended mode.

[0004] The application is implemented through the following technical scheme: an intelligent running management method for an unattended hydropower station, characterized by comprising the following steps:

[0005] (1) the operation on-duty management system automatically generates the next day unattended work task list of each hydropower station;

[0006] (2) the on-duty management system acquires the module data at a fixed time every day, automatically generates the next day unattended work task list of each hydropower station, or each hydropower station in a river basin manually enters the work task list in a standard format, and confirms and manually corrects the content of the work task list, and reports to the control center at a fixed time every day;

[0007] (3) The control center operator checks whether each power station in the basin reports the next day's unattended work task sheet on time according to the prescribed requirements. For the power stations that have reported, the operator carefully reviews and confirms the work task sheets reported by each power station in the basin. For the power stations that have not reported on time according to the prescribed requirements, the system will be automatically locked, and the control center can manually unlock to report;

[0008] (4) The operation shift management system classifies and summarizes the contents of the work task sheet, describes, locates, and retrieves the scattered information of each power station, classifies and layers the information based on the file description information and the extracted keywords, structures the information, facilitates the viewing of resource information through layering and classification, sets labels of emergency, importance, and general according to the importance of the classified information, and sorts the information according to the importance for use;

[0009] (5) The control center audits the work task sheets classified by the system and issues them to each power station;

[0010] (6) Each power station in the basin confirms the work task sheets issued by the control center;

[0011] (7) The work task sheets are executed;

[0012] (8) The operation shift management system stores and archives the work task sheet data into the database;

[0013] (9) The database is deeply mined, and the machine is self-learned.

[0014] In step (1), the shift management system obtains the module data at a fixed time every day, automatically generates the next day's unattended work task sheet for each power station, and manually enters the work task sheet through the standard format so as to effectively plan the next day's work through the work task sheet.

[0015] The module data includes maintenance work management module data, defect intelligence management module data, command operation module data, reservoir dispatching module data, and frequency modulation market module data.

[0016] The maintenance work management module data is set as the maintenance ticket content generated by the module, which has been started but not completed, and will be started next day;

[0017] The defect intelligence management module data is set as the defect treatment plan generated by the module, which generates the next day's defect treatment content;

[0018] The command operation module data is set as the dispatching command and control command generated by the module;

[0019] The reservoir dispatching module data is set as the reservoir water level, reservoir inflow and outflow, forecasted flow, and water level control plan of each power station generated by the module;

[0020] The frequency market module data is set as the next day pre-bid situation of each power station, the next day planned AGC exit period and work content generated by the module;

[0021] In order to generate an unattended work order.

[0022] In step (2), the work order automatically generated by the operation shift management system can be manually corrected by the power station, and reported to the centralized control center at a fixed time every day, so as to be modified and corrected by manual method to ensure the correctness of the instruction.

[0023] In step (3), the centralized control operator checks whether each power station in the basin reports the next day unattended work order on time according to the specified requirements. For the power stations that have reported, the centralized control operator needs to carefully review and confirm. For the power stations that have not reported on time according to the specified requirements, the system will be automatically locked, and the centralized control center needs to manually unlock it before reporting, so as to avoid accidents caused by mistakes.

[0024] In step (4), the operation shift management system classifies and summarizes the contents of the work order, describes, locates and retrieves the scattered information of each power station, classifies and layers the information based on the file description information and the extracted keywords, structures the information, and facilitates the viewing of resource information through layered and classified method. The classified information is set with emergency, important and general labels according to the importance, and sorted according to the importance for use.

[0025] The work order content includes operation, defect management, maintenance, and other matters needing coordination and communication of the centralized control center.

[0026] The operation part should have a safety anti-misoperation function. Through the data acquisition and control system of the monitoring system, the running state of the equipment is automatically matched and obtained, and it is verified whether the conversion of the initial state and the end state of the operation equipment meets the anti-misoperation rule and whether it has operation conditions under the current monitoring system equipment state. If both meet, the operation task order is generated according to the operation task. If any item does not meet, it returns to the previous process, and the corresponding anti-misoperation reminder should be popped up;

[0027] The defect management part automatically generates a defect processing order according to the alarm equipment and big data analysis. The operation shift management system obtains the defect list from the defect intelligent management system, including defect content, defect processing plan and safety measures required for defect processing, and generates the next day defect processing task order.

[0028] The maintenance part should have information retrieval and comparison function. Through offline files such as maintenance regulations, the corresponding content is intelligently retrieved to obtain safety measures, precautions and other requirements for maintenance work. The running state of the equipment obtained by the monitoring system is compared, and the necessity and rationality of the maintenance work are automatically judged. If the maintenance work meets the requirements of the regulations and the running state of the equipment meets the requirements, a maintenance task list is automatically generated, including maintenance content, safety measures, precautions, etc. Otherwise, return to the previous process;

[0029] Other matters needing coordination and communication of the control center include: temporary defect elimination, optimization of unit operation, unit rotation and other situations requiring assistance from the control center to adjust the operation mode, and other safety production coordination matters. The system defaults to "none". If there is a matter needing coordination and communication of the control center, the power station can manually input according to the actual situation;

[0030] In order to make a series of settings, so that the task can proceed smoothly and normally.

[0031] In step (5), the control center audits the work task list classified by the system and issues it to each power station.

[0032] In step (6), each power station in the basin confirms the feedback information from the control center to ensure the consistency of the control and the power station information, and achieves the purpose of information communication.

[0033] In step (7), the power station confirms the work task list and executes it. The execution link includes the execution of the power station's self-governance equipment work task list, the execution of the power station's work task list that needs to be coordinated with the control center or needs the control center's permission.

[0034] The power station self-governance equipment is set to the power station, which can directly carry out related work according to the work task list.

[0035] The power station needs to coordinate with the control center or needs the control center's permission, which submits a work application before the work is carried out, and can carry out the work after the control duty officer agrees.

[0036] In step (8), the operation duty management system stores and archives the work task list data into the database, which can be used in the big data intelligent analysis platform and the control operation handover scenario.

[0037] The archived storage data is introduced into the big data intelligent analysis platform for deep data mining to extract useful information and use text, tables and visual graphics to display data.

[0038] The unattended work task list is archived, and the control center operation is daily handed over to ensure the continuity and traceability of the work, and facilitate the operation management and control of the unattended power station.

[0039] In the step (9), the stored archived data is deeply mined to extract useful information, data regression analysis is performed, the analysis information is introduced into the robot interface, the learning behavior of human beings is simulated or implemented, the data is self-learned, and the machine learning system will find statistical structure from many examples related to a certain task, so as to finally find rules and continuously optimize and improve.

[0040] The present application has the following advantages and effects: by using the above scheme, the basin "unattended" power station and the centralized control center can communicate information through the operation duty management system, without repeated communication through the telephone, so as to improve the information communication efficiency of the centralized control and the "unattended" power station, effectively reduce the human cost of the centralized control and the power plant, and reduce the workload of the operation duty. The centralized control duty personnel can pay more attention to the risk analysis of the duty, the optimization of the unit operation and the increase of the power generation. The operation duty management system can collect information of other modules, automatically generate the next day unattended work task list, and the power station and the centralized control can orderly carry out the daily work according to the work task list, so as to improve the intelligent and intelligent level of the management of the centralized control center. For the conventional daily work, the functions of the machine start and stop reminding, the machine start order reminding, the water level exceeding limit reminding and the equipment periodic rotation reminding are provided. The safety risk of the equipment caused by the human factors and the information asymmetry is reduced, and the safe and stable operation of the basin hydropower station is promoted. The unattended management level of the basin hydropower station is standardized. The daily communication content between the unattended power station and the centralized control center is automatically generated by the system according to the standard template, which is convenient for storage, archiving and checking, can realize the whole process closed-loop management of the business, and improve the unified and centralized management level of the centralized control center to the power station. The historical database is deeply mined and analyzed, the data points of the model curve corresponding to the date are analyzed and predicted to predict the number of next day operation operations, the number of maintenance work and the number of defects. If the number of a certain type of the next day operation operation, the number of maintenance work and the number of defects is greater than the limit value, the classification labels with low importance are sequentially removed until the limit value is less than the limit value. The method avoids the excessive concentration of the operation work and the overload work of the operation duty personnel, and can effectively reduce the safety risk. The robot continuously learns the database information by training the model through various algorithms, identifies and predicts new problems by using these models, continuously improves the algorithm model, and automatically generates information that is more and more accurate, reasonable and guiding to the work. It is a ideal operation management method. BRIEF DESCRIPTION OF DRAWINGS
