Abstract:
We need a stable power system operation for reliable and quality power distribution. The system operation mode is prone to disruptions such as short circuits, and outages of large generating units and transmission lines, which cause parameter changes in the electric systems. The changes may lead to the emergence of electromechanical oscillations in synchronous generators reflected in the fluctuation of the parameters such as rotational speed, active and reactive power, voltage, and power output. In this process, it is possible to expect oscillations that can compromise the stable operation of the synchronous generator and the power system. The ideal method is to reduce the oscillations to use a stabiliser of the power system as an integral part of the excitation systems of generators. The excitation system can help the power oscillation stabiliser to complete the task. In the current work, we design the contemporary power system stabilizers and tested it using a finite illustration to measure the transient stability.
