摘　　要：对某1 000MW级汽轮机组调节系统实测数据进行分析,指出汽轮机经典模型的不足;提出通过增加主蒸汽压力对经典模型加以改进,改进模型的仿真结果与实测数据相符,证明了模型的可靠性;通过假定机组处于孤立电网中而模拟电网负荷降低以及电厂减负荷时整个孤网的动态特性,获得扰动曲线,为进一步研究汽轮机组调节特性提供了理论基础。The article analyzes measured data of regulating system of 1 000 MW-level turboset and it points out the shortcomings of classical model of the turbine.It is proposed to improve the classical model by increasing the pressure of main steam.The simulation result coincides with the measured data,which demonstrates the reliability of the model.In addition,the disturbance curve is acquired by means of dynamic characteristics of the entire stand alone system on the condition that the load of the simulated system is decreased and the load of the power plant is reduced,which offers theoretical basis to further study of regulating characteristics of turbines.
