Project Description
The application of automation in thermal power generation is extensive and profound. By introducing advanced automation technologies and equipment, thermal power plants have achieved comprehensive, real-time, and automatic control and management of the production process, significantly improving power generation efficiency, reducing operating costs, and effectively ensuring production safety. Here are several key aspects of the application of automation in thermal power generation:
1. Enhancing Power Generation Efficiency and Reliability
- Automatic Regulation of Boiler Combustion Systems: Employing automatic regulation strategies for boiler combustion systems enables optimal fuel combustion, thereby enhancing thermal efficiency. For instance, by collecting real-time data on furnace temperature, oxygen content, and flue gas composition, and combining it with advanced control algorithms, fuel supply, air volume, and secondary air distribution can be dynamically adjusted to maintain optimal combustion efficiency.
- Real-time Monitoring of Generator Units: Automation technology allows for real-time monitoring of generator units, promptly identifying and addressing potential faults to ensure the continuity and stability of the power generation process. For example, vibration monitoring and analysis techniques can be utilized to monitor critical components of generator units in real-time, detecting equipment anomalies early and preventing accidents.
2. Optimizing Control Processes
- Advanced Control Algorithms and Optimization Software: By adopting advanced control algorithms and optimization software, precise control over the entire power generation process can be achieved. For instance, Model Predictive Control (MPC) technology can optimize multiple variables in a power plant to achieve optimal operating conditions.
- Real-time Scheduling and Optimization: Automation technology also enables real-time scheduling and optimization of the production process, improving resource utilization and reducing energy consumption. For example, adjusting power generation output automatically based on grid load changes ensures the stability and economic efficiency of power supply.
3. Ensuring Equipment Safety
- Advanced Monitoring and Diagnostic Technologies: Introducing advanced monitoring and diagnostic technologies allows for real-time monitoring of equipment operating conditions, promptly identifying potential faults and hazards. For instance, infrared thermal imaging technology can be used to monitor the temperature of electrical equipment, preventing faults caused by overheating.
- Remote Control and Maintenance: Automation technology also facilitates remote control and maintenance of equipment, enhancing maintenance efficiency and safety. For example, through a remote monitoring platform, operation and maintenance personnel can monitor the status of all equipment in real-time, significantly reducing response times.
4. Specific Application Cases
- Boiler Combustion Optimization Control System (BOCS): A large thermal power plant introduced a BOCS to achieve refined control over the boiler combustion process. After implementation, the boiler thermal efficiency increased by 2.5%, NOx concentration in flue gas emissions decreased by 15%, and annual fuel cost savings exceeded ten million yuan.
- Intelligent Start-Stop System: A power plant applied an intelligent start-stop system to complete one-click start-up and grid connection, automatically increasing the load to the specified mode. This achieved a smart transition from empirical control to refined control, significantly improving the start-stop efficiency and safety of the unit.
- Primary Frequency Regulation Intelligent Evaluation and Optimization System: In response to the primary frequency regulation status in the service area, a power plant independently developed a primary frequency regulation intelligent evaluation and optimization system platform that integrates “grid-source coordination, assessment evaluation, and control decision-making,” effectively enhancing the primary frequency regulation quality of the unit.
