摘　　要：针对二次再热机组的一次调频负荷响应不足问题,以1000MW超超临界二次再热机组为研究对象,基于机理分析法建立二次再热机组一次调频动态仿真数学模型,开发实时动态仿真平台,仿真分析基于功频调节原理的一次调频动态特性。仿真结果表明:基于功频调节原理的一次调频方式在负荷响应速度及幅度方面均优于传统的频差调节方式,提高了机组的负荷响应能力,但对应的主汽压力波动幅度高于频差调节方式。Aiming at the problem of insufficient primary frequency control load response of the double-reheat unit,the 1000MW ultra-supercritical double-reheat unit is taken as the research object,and the mathematical model of the primary frequency modulation dynamic simulation of the secondary reheating unit is established based on the mechanism analysis method to develop real-time simulated dynamic platform,simulation analysis of the dynamic characteristics of primary frequency control based on the principle of load-frequency control.The simulation results show that the primary frequency control method based on the principle of load-frequency adjustment is superior to the traditional frequency deviationcontrol method in load response speed and amplitude,which improves the unit's load response ability,but the corresponding main steam pressure fluctuation amplitude is higher than the frequency deviationcontrol method.
