How to set Synchronous Machine in IEEE 11 Bus Model so that the system stable?
I am still building IEEE 11 bus model. I am going to make simulation using the model with various kind of exciter. I have finished the model by using Voltage Source Model instead of Synchronous Machine. I have tried to use Synchronous Machine but it is still unstable. The Model consists of 4 Generators, in Bus 1, 2, 3 and 4, which in Bus 3 is selected as Slack Bus. Could you please tell me how to set parameter of Synchronous Machine so that the system can be stable? What is different setting of parameters between Synchronous Machine in Slack Bus and others? Is the Synchronous Machine modeled as “Voltage Source” or “constant speed” mode?
