| چکیده | ||
| در این مقاله به منظور افزایش پایداری تأمین انرژی برق در سیستمهای توزیع به تعیین تعداد ترانسفورماتورهای مورد نیاز در انبار و مکان نگهداری آنها پرداخته است. برای تضمین قابلیت اطمینان در پستهای توزیع، ترانسفورماتورهای یدکی در هر پست مورد نیاز هستند. در صورت نبود ترانسفورماتور یدکی در یک پست، ممکن است خطای ترانسفورماتور منجر به قطع بار متصل به آن شود. از طرف دیگر، وجود ترانسفورماتور یدکی در هر پست بسیار پرهزینه خواهد بود. به همین دلیل در این مقاله به مسئلۀ تعیین مکان محل نگهداری ترانسفورماتورهای یدکی پرداخته خواهد شد. برای این منظور، تابع هزینۀ مورد نظر مطابق تابع فاصله در نظر گرفته شده است و از سه تابع فاصلۀ اقلیدسی، مجذور فاصلۀ اقلیدسی و فاصلۀ مستقیم استفاده میشود. آنچه جستوجو میشود، مکانی است که بتواند تابع هزینۀ کل تعیینشده را کمینه کند. برای این مهم یک روش ترکیبی (مارکوف و مونت‌کارلو) برای مدلسازی تعمیر و نگهداری ترانسفورماتور و سپس به تعیین مکان بهینه ترانسفورماتورهای یدکی پرداخته شده و از الگوریتم بهینهسازی نرمافزار Matlab جهت شبیهسازی استفاده شده است. مدل پیشنهادی در یک شبکۀ 33 شینه IEEE پیادهسازی شده و مشاهده میشود با تغییر اهمیت بار مکان ترانسفورماتورهای یدکی نیز تغییر میکند و این تغییر در روش فاصلۀ مستقیم شدیدتر است. | ||

| In order to increase the stability of electricity supply in distribution systems, this article has determined the number of transformers needed in the warehouse and their storage location. To ensure reliability in distribution substations, spare transformers are required in each substation. If there is no spare transformer in a post, the fault of the transformer may lead to disconnection of the load connected to it. On the other hand, having a spare transformer at each post would be very costly. For this reason, in this article, the problem of determining the location of spare transformers will be discussed. For this purpose, the desired cost function is considered according to the distance function, and three functions of Euclidean distance, squared Euclidean distance and direct distance are used. What is searched for is a place that can minimize the determined total cost function. For this purpose, a combined method (Markov and Monte Carlo) has been used to model transformer maintenance and then to determine the optimal location of spare transformers, and Matlab software optimization algorithm has been used for simulation. The proposed model has been implemented in a 33-bus IEEE network and it can be seen that the location of the spare transformers also changes with the change in the importance of the load and this change is more intense in the direct distance method. | ||
