[0001] The invention belongs to the technical field of electric power, and in particular discloses an intelligent alarm system and an intelligent alarm method for a hydroelectric power station. Background Art

[0002] In the hydropower industry, the intelligent construction of hydropower plants should include rich content at different levels. The current digitalization, intelligentization and wisdom construction are the specific manifestations of different levels. Digitalization mainly focuses on the intelligence and network interconnection of equipment on the production site of hydropower stations, which is the foundation and support. Intelligence focuses on the construction of an integrated platform for the entire plant and intelligent advanced applications. Wisdom is to establish a highly scalable multi-source massive data unified management and analysis big data platform at a higher enterprise level through the application of new IT technologies such as cloud computing, big data, the Internet of Things, mobile Internet, and artificial intelligence. It brings together real-time and non-real-time production and management data from various businesses from a wide range of sources, realizes data integration and in-depth mining, and forms rich data monitoring, data mining, data statistics, analysis and prediction, command decision-making and comprehensive display functions.

[0003] The traditional computer monitoring system of hydropower plants has the following prominent problems: the number of real-time alarm signals is large, and the alarm signals of multiple hydropower plants appear mixed; the alarm signals come from multiple hydropower plants, and the naming of alarm signals is not standardized and rigorous; there are deficiencies in the monitoring systems of each centralized power plant, and when hidden abnormalities or defects occur in the operation of on-site equipment, alarms cannot be pushed in the first time.

[0004] Existing hydropower plant monitoring systems rely primarily on manual judgment, lacking intelligent and early warning capabilities. They lack trend analysis and early warning capabilities. Conventional hydropower plant computer monitoring system data alarms primarily address direct alarms at measurement points, such as switch position change alarms, analog limit violations, and gradient alarms. Trend analysis and early warnings cannot be performed through curve comparison or other methods. Instead, operators rely solely on their on-duty experience for predictions, failing to meet the requirements of intelligent alarms.

[0005] CN115664344A discloses a device and method for automatic fault alarm of photovoltaic power station, which belongs to the field of photovoltaic power generation. The device comprises a support plate, a photovoltaic panel is fixedly connected to the side surface of the support plate, a base is provided under the support plate, the support plate is fixedly connected to the base through a bracket, and a cleaning mechanism is provided on the outside of the photovoltaic panel; the cleaning mechanism comprises slide plates with L-shaped structures symmetrically distributed on the left and right ends of the photovoltaic panel, slide rails are symmetrically fixedly connected to the left and right sides of the lower side surface of the support plate, rollers are provided inside the slide rails corresponding to the slide plates, the rollers are fixedly connected to the slide plates through a rotating shaft, and the two slide plates are rotatably connected to the center positions of the sides corresponding to the vertical parts of the photovoltaic panel.

[0006] The above-mentioned prior art cannot solve the above-mentioned technical problems of existing hydropower plants. Summary of the Invention

[0108] Further implementation methods are as follows:

[0109] Step 1: Integration of intelligent alarm and computer monitoring system

[0110] The hydropower station's intelligent alarm system deploys the IMC6 system on the intelligent alarm server, enabling two-way communication with the running IMC3 monitoring system to import and analyze measurement point data. On this basis, the system integrates data collection, analysis, and linkage functions to provide core support for intelligent monitoring and alarm management:

[0113] Step 2: Background data processing and equipment status analysis

[0114] The system backend uses intelligent algorithms to perform in-depth analysis and trend prediction of equipment operating status, providing support for accurate alarms and rapid emergency response:

[0115] Real-time data storage and historical data import: The backend collects and stores real-time data from the production control area, and supports the import and analysis of historical data from various systems;

[0116] Intelligent threshold learning: Based on the equipment model, it automatically learns historical data to form alarm thresholds under different working conditions and dynamically corrects them to improve the accuracy and intelligence of alarms;

[0117] Trend analysis and prediction: Combined with equipment operating parameters, vertical and horizontal trend analysis is carried out. When status parameters significantly deviate from the set value or historical average level, an alarm is generated and recorded.

[0118] Step 3: Intelligent Screen Patrol and Report Automation

[0119] Intelligent screen inspection and reporting functions provide efficient and convenient support for operation and maintenance:

[0120] Intelligent patrol screen: Automatically inspect the operating parameters of all electromechanical equipment in the station every two hours, record and analyze the data, and generate Excel documents for easy reference;

[0122] Specific data statistics: Regular statistics on equipment operating parameters, start and stop time, energy storage motor operation times, etc., provide accurate data support;

[0123] Reservoir water level statistics: The system automatically generates daily maximum and minimum reservoir water level statistics and change trends to assist management decisions.

[0124] Step 4: Intelligent trend analysis and troubleshooting decisions

[0125] The system provides intelligent status monitoring and fault-assisted decision support based on equipment operating parameters and historical data:

[0126] Multi-dimensional trend analysis: Combine operating conditions and historical data to analyze equipment operating efficiency and potential hazards, identify possible causes of sudden changes, and issue early warnings;

[0127] Auxiliary fault location: Based on alarm data and equipment status, it provides possible fault causes and equipment location suggestions to help operators respond quickly;

[0128] Fault handling suggestions: Through the built-in fault handling knowledge base and combined with historical cases, it provides handling measures, emergency plans and safety risk assessments.

[0129] The key points of the invention are:

[0130] 1. It can provide trend warnings, anticipate abnormal defects, and nip accidents in the bud. Based on historical equipment data and multi-operational models, this system automatically learns and calculates alarm thresholds for different equipment states, dynamically adjusting them as equipment operating conditions change. This system identifies potential anomalies in advance, avoiding false alarms or missed alarms caused by fixed threshold settings.

[0131] 2. Comprehensive alarm information and flexible judgment conditions. The intelligent alarm system no longer uses a single monitoring or simple logic to issue an alarm, but instead uses multiple measurement points to make combined judgments based on certain conditions and then issues an alarm.

[0132] 3. Equipped with emergency guidance, capable of providing effective guidance and assistance in emergency response after an alarm is issued. After an alarm is issued, guidance and suggestions on alarm handling methods will be provided based on the relevant content in the compiled typical operation experience database.

[0133] 4. It has a multi-device linkage function. After an alarm occurs, it uses on-site cameras and other sensing devices to conduct further inspections of the location where the abnormality occurred.

[0134] The present invention has the following main beneficial technical effects:

[0135] 1. This technical solution implements intelligent monitoring functionality on the IMC6 system and communicates with the IMC3 system, enabling real-time data collection and unified management of various measuring points at the hydropower station. This centralized data pool eliminates information silos between systems and improves data collection efficiency and accuracy. Furthermore, validation and correctness checks on collected data filter out invalid information, fundamentally improving data quality. Data integration across monitoring systems provides a comprehensive and reliable foundation for subsequent analysis, significantly enhancing data liquidity and utilization.

[0136] 2. The technical solution establishes a dynamic threshold model for equipment operation through automatic learning and analysis of historical data, enabling real-time adjustment of alarm thresholds based on varying operating conditions. Through vertical and horizontal comparative analysis, it not only identifies abnormalities in equipment operating status but also predicts future trends and provides early warnings. Intelligent analysis of long-term operating trends identifies potential operational hazards and provides a basis for preventive maintenance. This multi-dimensional status monitoring and analysis improves alarm accuracy and timely response, significantly reducing the probability of equipment failure and operational risks.

[0137] 3. The deep integration of intelligent screen patrol and automated reporting replaces traditional manual recording and analysis, significantly reducing the burden on operators. Automatically generating various operational reports and fault analysis reports ensures data accuracy and timeliness, while also providing log files for easy subsequent query and optimization. The automated screen patrol function makes operational status monitoring more regular and comprehensive, facilitating timely problem detection. Furthermore, the emergency fault status notification function, integrated with industrial television, helps operators quickly and intuitively understand equipment failures and make informed decisions, further improving operational efficiency.

[0138] 4. This solution's assisted fault location and resolution function combines historical alarm data with operating conditions to provide multiple actionable suggestions, helping operators quickly and accurately locate problems and take corrective action. The establishment of a knowledge base of fault resolution results provides an intelligent reference for resolving similar issues, significantly improving processing efficiency and safety. Furthermore, the emergency status push function ensures that relevant information is promptly delivered to responsible personnel and management, ensuring a swift response to emergencies. The linkage and integration of multiple systems further enhances the synergy of equipment anomaly resolution, providing a strong guarantee for the efficient and stable operation of the system.

[0139] The above embodiments are merely preferred technical solutions of the present invention and should not be construed as limiting the present invention. The scope of protection of the present invention shall be the technical solutions described in the claims, including equivalent alternatives to the technical features of the technical solutions described in the claims. Equivalent alternatives and improvements within this scope are also within the scope of protection of the present invention.
