Improving the Transient Stability of a Synchronous Generator by Using Braking Resistance to Increase the Critical Clearing Fault Time

In general, the stability of the power system can be considered a feature of the system that enables it to remain in equilibrium under normal conditions and regain a different acceptable state if affected by disturbance. Instability in a power system may take many forms, depending on the composition of the system and its operating modes. In order to evaluate the proposed method in damping transient fluctuations and network stability, a study has been carried out on a typical network. Since the topic of the article is in the field of transient stability, in part of the paper, braking resistance modeling in transient stability studies has been investigated. In the section on brake resistor control, brake resistor control is introduced by a switched Thyristor, using the trapezoidal method. Finally, the simulation results of the studied network are presented with the presence of TCBR and its capability of damping in the desired network.
