摘　　要：针对目前火电机组的数值建模和纯手工建模存在的仿真系统单一和建模工程量大等缺点,利用模块化建模方法建立了某660 MW超临界直接空冷燃煤火电机组的全系统仿真模型。该模型具有高度的静态模拟精度,能够准确预测实际机组在不同工况下的主要参数。此外,该模型还具有高度的动态模拟精度,在模拟凝结水节流的动态过程中,展示了良好的负荷、水位和压力动态特性。In view of the shortcomings of single simulation system and large amount of modeling work in the current numerical modeling and pure manual modeling of thermal power units, the whole system simulation model of a 660MW supercritical direct air-cooled coal-fired thermal power unit is established by using the modular modeling method. The model has high static simulation accuracy and can accurately predict the main parameters of the actual unit under different working conditions. In addition, the model also has high dynamic simulation accuracy, and shows good dynamic characteristics of load, water level and pressure in simulating the dynamic process of condensate throttling.
