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

Abstract

يعتبر استخدام مخمد اهتزاز إلى منظم الجهد الآلي في نظام التهييج لمولد ضمن نظام للطاقة الكهربائية واحداً من الحلول الحديثة لتحسين استقرار نظم الطاقة الكهربائية. إن مخمد الاهتزاز يقدم عزوم تخامد متوافقة بالطور مع سرعة الدوار مؤدية إلى تقليل التأثيرات السلبية للاهتزازات. يلعب توليف ثوابت مخمد الاهتزاز دوراً أساسياً في تحسين أداء النظام. يهدف هذا البحث إلى اعتماد طريقة الحل الأمثل في توليف ثوابت المخمد. تم نمذجة نظام طاقة متعدد الآلات يحوي على أربع محطات حرارية. زودت كل محطة بمخمد اهتزاز، ورسمت الاستجابات الزمنية لبعض من متحولات النظام عند الثوابت المختارة بطريقة الحل الأمثل و الثوابت الاسمية. أعطى النظام تخامداً  جيداً عند توليف الثوابت على أساس الحل الأمثل.

 

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
