在纯凝汽式机组负荷-压力对象简化非线性动态模型基础上,结合对抽汽式供热机组供热部分热力系统的分析,依据基本物质和能量守恒定律,建立了供热机组发电负荷-汽轮机前压力-供热抽汽流量与锅炉燃料量-汽轮机高调门开度-抽汽调节蝶阀开度的微分方程形式的动态模型.通过仿真实验证明：供热机组与纯凝汽式机组发电负荷-汽轮机前压力对象控制特性不存在显著差异;供热机组可采用更为灵活的控制方式以提升发电负荷调节速率.

Based on simplified nonlinear dynamic model of load-pressure object for pure condensation unit,in combination of analysis on thermodynamic system in heat-supply part of extraction steam turbine,according to the basic law of conservation of energy and mass,a differential equation model of load-throttle pressure-extraction steam flow versus boiler fuel flow-turbine governor valve＇s opening-extraction control valve＇s opening was constructed for heat supply units.Simulation results show that there is no significant difference between heat supply units and pure condensation units in the control characteristics of load-throttle pressure object.For heat supply units,it is recommended to take more flexible control modes to promote the load up/down rate.
