发电机模拟无穷大系统
怎样设置一台发电机可以代表无穷大系统,动态参数该如何设置,求高人指点 回复 1# qcsun同问,貌似手册里是这么设的
IBUS,'GENCLS',1,0.0000,0.0000/
但是好像母线电压会变化?不知道为什么? 是啊,电压和一般母线差不多 回复 3# qcsun
PTI的回复是“When you use model a machine using the GENCLS model, the internal voltage remains constant and not the terminal voltage.” 那如果能把它的暂态电抗设为0就可以了,可好像没法设吧 回复 5# qcsun
同问,为什么要把暂态电抗设为0呢 回复 5# qcsun
In PSSE, the classical generator model is used to represent theinfmite bus. Forthe classical generator to bea constant
voltage and constant frequency source, the inertia constant of the machine is set to zero as required in . In this model, the
d-axistransientreactanceisequaltothesynchronous reactance(Xd = Xb). In transientcalculations, this reactance
represents the short circuit reactance at the infmite hus. 教程中有吧,电压恒定,容量设置一个较大的数值 the classical generator model is used to represent theinfmite bus。 我用过把D和H设成无穷大(9999),也行的。
