| Abstract (English): | Recently, researchers have focused their efforts to generate electricity on renewable energy sources. Wind power systems are considered good alternative sources of clean energy. Induction generators are the best choice for generating this energy due to their simplicity, robustness, and low maintenance requirements. However, their main drawback is their need for leading reactive power to build the terminal voltage and generate electrical power. This drawback can be overcome using a terminal capacitor across the generator terminals to generate this leading reactive power. This research focuses on: 1-Provides a methodology for selecting an accurate and reliable value of the excitation capacitance required for self-excited induction generators (SEIG), which can be used in pumps operating as turbines (PATs + SEIG). When operating at different speeds and loads. For these systems, the choice of capacitance for the SEIG is of utmost importance. 2- A simplified and understandable method derived from nodal analysis is presented for calculating the exact excitation capacitance of a self-excited induction generator (SEIG) under various conditions. 3-A new analysis and model of (SEIG) is presented. The proposed model consists of an induction generator, a self-excited capacitor, and a RL load. It is used to study the performance of SEIG under different faults and excitation (sudden short circuit, unbalanced excitation, sudden load surge, sudden disconnection of excitation capacitance, and load disturbance). Simulations are created using MATLAB-SIMULINK to validate the proposed model. [ABSTRACT FROM AUTHOR] |
| Abstract (Arabic): | يركز المقال على تطوير طريقة موثوقة ومبسطة لاختيار قيمة السعة التحفيزية الدقيقة المطلوبة للمولدات الحثية ذات الإثارة الذاتية (المعروفة بـالمولدات الحثية ذات الإثارة الذاتية أو SEIG)، لا سيما عند التشغيل تحت ظروف مختلفة من الأعطال والإثارة. باستخدام تحليل الموصلية العقدية، يستخلص البحث نموذجًا رياضيًا في الحالة المستقرة لحساب الحد الأدنى من السعة التحفيزية اللازمة لهذه المولدات، التي تُستخدم بشكل شائع في تطبيقات الطاقة المتجددة مثل توربينات الرياح والمضخات التي تعمل كتوربينات (المضخات العاملة كتوربينات أو PATs). تم التحقق من صحة الطريقة المقترحة من خلال محاكاة باستخدام برنامج MATLAB-Simulink، حيث تم تحليل الاستجابات العابرة تحت ظروف أعطال تشمل دوائر قصر مفاجئة، وزيادات الحمل، وعدم توازن الإثارة، وانفصال السعة التحفيزية. تشير النتائج إلى أن قيمة السعة التحفيزية تؤثر بشكل كبير على بناء الجهد واستقراره، وأن مقاومة الحمل وسرعة الدوار تؤثران على السعة المطلوبة، مع فشل المولد في الإثارة الذاتية عند انخفاض السرعات أو تجاوز حدود السعة الدنيا.
