کلید واژه: توربین بادی زاویه گام کنترل‌کننده تطبیقی یادگیری عاطفی,
چکیده مقاله :
يکي از روش‌هاي کنترلي مرسوم در توربين‌هاي بادي، کنترل زاويه گام پره‌هاي توربين مي‌باشد که اين کار به منظور داشتن توان نامي در خروجي توربين، براي سرعت‌هاي باد بالاتر از سرعت باد نامي انجام مي‌گيرد. با توجه به اهميت زياد کيفيت توان توليدي توسط توربين و از آنجا که عملکرد بهتر کنترل‌کننده زاويه گام، کيفيت بهتر خروجي سيستم زاويه گام و متعاقباً کيفيت بهتر توان توليدي توربين را به دنبال دارد، بهينه‌سازي عملکرد اين کنترل‌کننده امري حياتي است. در اين مقاله ابتدا براي کنترل زاويه گام از يک کنترل‌کننده PI استفاده شده و سپس يک کنترل‌کننده هوشمند عاطفی جدید (برگرفته از مکانيسم يادگيری عاطفی مغز انسان) جايگزين آن گرديده است. با توجه به نتايج شبيه‌سازي با اين جايگزيني، عملکرد سيستم کنترل زاويه گام در حد بسيار خوبي بهبود يافته است. اين کنترل‌کننده هوشمند عملکرد خوبي از لحاظ سرعت پاسخ‌دهي، ريپل پاسخ و بالاخره خطاي ماندگار رديابي داشته و در ضمن از قوام قابل ملاحظه‌اي در قبال تغييرات سرعت باد (نقطه کار) و پارامترهاي سيستم زاويه گام برخوردار است.
The purpose of this paper is optimal location of distributed generation in electric distribution networks. Load uncertainty and desired voltage range has been modeled using fuzzy data theory. The objective function includes loss reduction, improvement of profile index and voltage stability index with their relevant constraints, voltage constraints and transmittable power from the line. Load variation has been shown for three different time durations (peak, off peak and average).PSO technique has been used to optimize the objective function while Max-Min method has been applied to select the answer. Results produced from the proposed model have been provided in 5 different scenarios on a 33 bus system of IEEE.
