It has become the main choice for many power plants in China. However, the design and operation of such units are very complex, which requires a complete and accurate model to predict the performance of the unit. Therefore, the theoretical and methodological research on modeling of 1000MW ultra-supercritical units is of great significance for the development of the power industry.Research ObjectivesThe main objectives of this research are:1. To establish a comprehensive and accurate model for 1000MW ultra-supercritical units.2. To investigate the performance of the unit under different operating conditions and load changes.3. To analyze the influence of different factors on the operation of the unit.4. To propose suggestions for optimizing the operation of the unit.Research MethodsThe research will be divided into two parts: model establishment and model analysis. The model establishment part will mainly focus on the following aspects:1. Build a mathematical model of the unit, including the boiler, turbine, and auxiliary equipment.2. Develop a simulation software to implement the model and simulate the actual operation of the unit.精品文档---下载后可任意编辑3. Validate the model using the operation data of the unit and conduct sensitivity analysis to determine the important variables.The model analysis part will mainly focus on the following aspects:1. Investigate the operation of the unit under different conditions, such as different loads, ambient temperatures, and coal types.2. Analyze the influence of different variables on the performance of the unit, such as fuel consumption, heat loss, and emissions.3. Optimize the operation of the unit based on the simulation results.Expected Results1. A comprehensive and accurate model of 1000MW ultra-supercritical units will be established.2. The performance of the unit under different operating conditions and load changes will be investigated.3. The influence of different factors on the operation of the unit will be analyzed.4. Suggestions for optimizing the operation of the unit will be proposed.ConclusionThis research will provide a scientific basis for the operation, control, and optimization of 1000MW ultra-supercritical units. It fills the gap in the research on modeling of such units and provides a theoretical and methodological reference for further research on the power industry.
