Abstract :
In recent years, using controllable series device (CSD) such as controllable series capacitors (CSCs) has been considered to improve transient stability and damp power oscillations. These devices can be useful if they have suitable input signals and control strategy. In this paper base on Lyapunov theory mixed with fuzzy control system (FLC) a useful controller has been developed for damping the electromagnetic power oscillations in a single machine power system. To simulate CSC device an injection model is used. This model is valid for load flow and angle stability analysis and is helpful for understanding the impact of the CSD on power system stability. Simulation results show that fuzzy Lyapunov function has a good performance in damping power oscillation and it can improve transient stability in power systems.
