چکیده

این مقاله استفاده از تحلیل حساسیت مسیر در سیستم‌ها‌ی تولید پراکنده (DG) را بررسی می‌کند. نشان داده می‌شود که روش ذکر شده می‌تواند در تعیین اثر پارامترهای کنترلی توربین بادی متصل به ژنراتور القایی تغذیه دوبل (DFIG) در برابر تغییر سرعت باد و تغییر امپدانس خط انتقال بر روی پایداری گذرای سیستم مفید باشد. برای مشخص نمودن مقدار حساسیت توربین بادی متصل به ژنراتور القایی تغذیه دوبل نسبت به 10 پارامتر کنترلی در برابر تغییر سرعت باد و تغییر امپدانس خط انتقال، متغیرهای حالت سیستم و لغزش DFIG مورد بررسی قرار می‏گیرند. با توجه به بررسی‏ها و شبیه‏سازی‏های انجام گرفته می‏توان به طور کلی به این نتیجه رسید که پارامترهای کنترلی تناسبی از پارامترهای کنترلی انتگرالی اهمیت بیشتری در رفتار DFIG دارند. همچنین پارامترهای کنترلی از نظر اهمیت تأثیرگذاری بر روی رفتار DFIG تقسیم‏بندی می‏شوند.

چکیده [English]

Economic and environmental conditions often make large stations and transmission lines, restrictions are placed. Small and medium-sized production units connected to existing systems as a strategy is in progress. These units are usually near the center of the load placed and distributed generators (DG) famous are the DG are allowed types vary, such as induction generators rack squirrel-connected wind turbines, generators fed induction double mounted wind turbines, fuel cells connected to the system by power electronic converters or synchronous generator connected to the turbine combustion [10]. This way sensitivity analysis in systems of distributed generation (DG) is assessed. It is shown that the method can detect the effect of control parameters listed wind turbine connected to a double-fed induction generator (DFIG) Badoou the impedance of the changing the speed of on the stability of the transmission line useful system invested. The control parameters of the importance of influencing the behavior of DFIG are divided.
