摘　　要：以QF-6-2型汽轮发电机为例,采用集总参数方法建立了相应的等效风路模型。应用函数风阻法并引入遗传算法对发电机通风系统风量分布分别进行了计算,并与实测结果进行了对比,计算精度符合工程计算的要求,证实了该模型的正确性。Within the framework of lumped method, an equivalent ventilation network model was established. And as an example of QF-6-2 turbogenerator, the function resistance approach and the genetic algorithm are introduced respectively to retrieve the flow rate distribution of ventilation system. The test data and the results from numerical simulation show a basic agreement, indicating the validity of the erected model as well as its conformity to the engineering requirements.
