Abstract

This paper provides an overview of a dynamic analysis carried out on the large-scale Queensland transmission network. This paper highlights how decaying voltages and the subsequent hyper-excitation of generators can lead to transient oscillatory instability because of insufficient damping torque. Different levels of voltage compensation have been implemented at critical generators in the model to determine the impact these different control levels may have on the time to voltage collapse following a system contingency.
