ملخص المقالة :
به مجموعه روش‌هایی که بعد از بروز خطا، موقعیت خطا را با توجه به شرایط قبل و بعد از خطا تشخیص می‌دهند، الگوریتم‌های مکان‌یابی خطا گفته می‌شود و بخشی که این کار را انجام می‌دهد، مکان‌یاب خطا نامیده می‌شود. در همین رابطه مفاهیمی چون تشخیص خطا و جداسازی آن و تشخیص خطا و سرمنشأ آن نیز در سیستم قدرت مطرح شده است. تا کنون روش‌های مختلفی به منظور تشخیص خطا و سرمنشأ آن در بخش‌های مختلف سیستم قدرت و نیز تجهیزات آن نظیر ترانسفورماتورها، مبدل‌ها، خطوط هوایی، کابل‌های زمینی، فیدرها، مدارشکن‌ها، رله‌های حفاظتی، ژنراتورها، توربین‌ها و غیره معرفی شده است که هر کدام در تکمیل کارهای گذشته، روشی جدید و کارآمدتر را پیشنهاد داده‌اند. در این مقاله، مطالعه جامعی روی روش‌های تشخص خطا و تعیین سرمنشأ آن در سیستم‌های توزیع برق ارائه شده است. همچنین دسته‌بندی و روش‌شناسی تحقیقات صورت گرفته پیرامون این موضوع در مقالات مختلف، بیان شده است. الگوریتم‌های تشخیص خطا و تعیین مکان خطا از دو دیدگاه کلی تقسیم‌بندی شده و ویژگی‌های هر دسته به صورت کامل تشریح شده است.
