[ 1 ] - تعیین یک مدل جدید بر اساس الگوریتم تبدیل فوریه گسسته برای مطالعه پدیده فوق اشباع در طی برق دار کردن ترانسفورماتور قدرت بدون بار با امپدانس یا بار اضافه از سمت منبع و تاثیر آن بر حفاظت دیفرانسیل
یکی از عملکردهای ناخواسته حفاظت دیفرانسیل ترانسفورماتور در طی برق‌دار کردن ترانسفورماتور بدون بار به همراه یک امپدانس یا بار اضافی از سمت منبع (اولیه) رخ می‌دهد که ناشی از پدیده‌ای موسوم به پدیده فوق اشباع است. این پدیده مشکلی بزرگ برای حفاظت ترانسفورماتور قدرت ایجاد می‌کند. در این مقاله برای نخستین بار مدلی جدید بر اساس الگوریتم تبدیل فوریه گسسته برای بررسی پدیده فوق‌اشباع در هنگام برق‌دار کرد...
[ 2 ] - A New Model for Analysis of Unusual Mal-Operation of Differential Protection Due to the Ultra-Saturation Phenomenon during the Loaded Power Transformer Energization
In this paper, a new model based on the thevenin equivalent circuit for investigating the ultra-saturation phenomenon during the energization of a loaded power transformer is presented and its effect on the differential protection of the transformer is considered. The ultra-saturation phenomenon causes the mal-operation of the power transformer differential protection. So, the description a...
