Abstract: This paper present an enhanced adaptive scheme for the stabilization of multi machine power systems The dynamic interaction of the power system is taken into account in deri ving the generator stabilizing signal by developing an external dynamic equivalent model at the sub system terminals The generator model and external dynamic equivalent model are combined in order to have an overall design model in an input output form The stabilizer is designed using the self tuning regulator concept of adaptive control An online MIMO recursive least square identification algorithm and a generalized minimum variance control technique are used for the stabilizer design Simulation test results show the effectiveness and the superiority of the proposed adaptive enhancement scheme over both fixed parameter conventional stabilizers as well as adaptive stabilizers designed without consideration of the power systems interactions
تعرض هذه الورقة مشروع تحسين موازنات نظم القوى الكهربائية باستخدام النموذج اللامركزي المتكيف وقد أخذ في الاعتبار تأثير التفاعلات الخارجية عند التصميم وذلك بإيجاد نموذج مكافئ، وتم دمجه مع نموذج المولد للوصول إلى نموذج كلي متكيف وبعد ذلك صمم الموازن باستخدام طريقة التحديد المتواصل لإيجاد ثوابت النموذج بالإضافة إلى لوغاريثم التحكم (تقليل المنازعة) إن نتائج المحاكاة أثبتت فاعلية النموذج المقترح في تحسين أداء نظم القوى
