استخدام طريقة الحل الأمثل لتوليف ثوابت مخمد الاهتزاز وأثره على تحسين استقرار نظم الطاقة الكهربائية

The application of power system stabilizers (PSS) to the automatic voltage regulators on the generators in the power system is considered as a contemporary solution of improving power system stability. The torque-damping in line with rotor speed provided by the power system stabilizer provides the means to reduce the inhibiting effects of the oscillations. The tuning of power system stabilizer parameters mainly contributes to the enhancement of stability. In this research, an optimal solution for tuning PSS parameters has been considered. A multi-machine power system including four power generators has been devised. Each generator is fitted with a PSS then the time response of some variables has been drawn with optimal PSS parameters and nominal parameters. The adopted system has provided good damping with maintained optimal parameters
