摘要
以一台300MW大型汽轮发电机为例,分别按照"场"、"路"两种不同方法计算了其相关参数,并讨论了两种计算方法的区别及意义.最后,通过对"单机—无穷大系统"模型进行扰动仿真,证明了按照"场"方法计算得出的参数更适用于电力系统的动态仿真.
In this paper,a group of 300MW turbo-generator parameters is calculated according to different calculation methods-circuit and field.The differences and calculation significance of the two methods are discussed.Finally,by simulating disturbance on the model of single generator-infinite bus,the parameters from field method are demonstrated better for power system simulation.
