Wind power applications of doubly-fed reluctance generators with parameter-free hysteresis control
آشنایی با موضوع
اگر مصرف کننده سلف خالص باشد در این صورت منحنی ولتاژ و جریان با یکدیگر 90درجه اختلاف فاز خواهند داشت و نیمی از منحنی توان در ناحیه + و نیمی دیگر در ناحیه منفی قرار دارد در این حالت توان اکتیو صفر است
در مصرف کننده هایی که بین ولتاژ و جریان آنها اختلاف فاز وجود دارد توان دارای دو مقدار مثبت و منفی است به این معنی که مصرف کننده گاهی از شبکه توان می کشد و گاهی به آن توان می دهد این موضوع سبب ایجاد توان راکتیو می شود از آنجایی که در این مصرف کننده ها امکان صفر کردن اختلاف فاز ممکن نیست نتیجه این می شود که توان راکتیو را نمی توان از بین برد .
برای جریان‌ها و ولتاژهای سینوسی که بسامد یکسانی دارند، توان راکتیو بر حسب وار عبارت است از حاصلضرب جذر متوسط مربع جریان و ولتاژ (توان ظاهری)، ضربدر سینوس اختلاف فاز بین ولتاژ و جریان. توان راکتیو Q (که با واحد ولت-آمپر راکتیو یا وار اندازه‌گیری می‌شود.
در مهندسی برق همیشه نیم سیکل مثبت را در نظر میگیریم به این خاطر است که سلف را مصرف کننده ی توان راکتیو و خازن را تولید کننده مینامیم و الا در نیم سیکل منفی سلف است که توان راکتیو تولید می کند و خازن مصرف کننده است
