摘要
介绍了火电机组的一次调频特性,建立了超超临界汽轮机的一次调频数学模型,通过MATLAB仿真验证了数学模型的正确性。基于数学模型,分析了汽轮机定压运行、滑压运行和定-滑混合运行模式下的仿真结果。该数学模型的研究成果对机组调试具有重要意义,可用于指导电厂运行。
The primary frequency modulation characteristics of thermal power units was presented.A simulation mathematical model of primary frequency modulation of ultra-supercritical steam turbine was established,and the correctness of this model was verified by MATLAB simulation.Based on mathematical model,the simulation results of steam turbine under constant pressure operation,sliding pressure operation and fixed-sliding mixed operation mode were analyzed.The mathematical model is of great significance for unit commissioning,and can provide guidance for power plant operation.
