الملخص

أنظمة نقل وتحويل الطاقة الكهربائية ضرورية في عملية توفير الطاقة من التوليد إلى الاستهلاك. ومع ذلك، فإنها لا تعمل دائمًا الى النحو المنشود. تبحث هذه الدراسة في كيفية أداء محطة فرعية 31.5 ميجا فولت أمبير و33/11 كيلو فولت بكفاءة أكبرعند اضافة مجموعة مكثفات ثابتة 3 ميجا فولت أمبير في علي شكل (نجمة - نجمة ) لتحسين معامل القدرة , تم استخدام حزمة برامج محاكاة لتحليل الاداءعند تغيير  النسبة المئوية في سعة التحميل الكاملة من 10٪ إلى 100٪. كانت نتائج تعويض مجموعة المكثفات أكثر وضوحًا، عند تغيير الحمل 40% إلى 10% ؛ وكانت عوامل القدرة 0.77-0.97 على التوالي . أُجري تقييم أكثر تفصيلًا عند 50% من الحمل لدراسة تأثير تركيبات مختلفة من مجموعات المكثفات(نجمة - نجمة و نجمة-نجمة- ارضي ، ∆+ ∆ و∆) على أداء المحطة الفرعية. ووفقًا للنتائج، حسّن تكوين ربط المكثفات على شكل ∆ معامل القدرة من 0.645 إلى 0.962 عند 50% من الحمل، مما يُتيح تصحيحًا أفضل لمعامل القدرة مقارنةً بالتكوينات الأخرى.
