"welwyn, though far from perfect, made the new towns act possible, just as hatfield, by its imperfection, made it necessary.

who created seven heavens one upon another. thou seest not in the creation of the all-merciful any imperfection. return thy gaze; seest thou any fissure?
آن خدایی که هفت آسمان بلند را به طبقاتی منظم بیافرید و هیچ در نظم خلقت خدای رحمان بی‌نظمی و نقصان نخواهی یافت، باز بارها به دیده عقل بنگر تا هیچ نقص و خلل هرگز در آن توانی یافت؟

high torque density pmsgs are desired for compact wind turbines, and they are usually designed to operate close to the nonlinear region for better usage of the electromagnetic materials. this makes sinusoidal flux linkages difficult to achieve by means of machine design optimization techniques [33], resulting inevitably in torque, current and voltage harmonics. typically, torque ripples varying periodically with the rotor position at six times the electrical frequency (6th order harmonic) result from dominant 5th and 7th harmonics in the back-emf. additional torque ripples may appear due to manufacturing imperfections [34]-2nd order harmonic—and in fault-tolerant modes, for instance, a multi-phase machines operating with a reduced number of phases [35]. control of the generator-side converter is typically based on vector control as described in textbooks [32] but may include additional features. as an example, control solutions for torque ripple minimization are mandatory in wind turbine applications to reduce acoustic noise and fatigue, allowing manufacturers to meet noise standards and component life-time targets. torque ripple minimization is achieved by means of stator current injection, producing a counteracting torque ripple component. for the desired harmonic current injection, closed-loop harmonic current controllers can be specifically designed to achieve zero steady-state errors and satisfactory dynamic performance [36,37,38]. these remarks regarding generator current control are relevant for fault diagnosis because fault signatures based on harmonic analysis of electrical signals (current, voltage, power) can be altered by the chosen control algorithms and parameters.
pmsg های با چگالی گشتاور بالا برای توربین های بادی فشرده مورد نظر هستند و معمولاً طوری طراحی می شوند که نزدیک به ناحیه غیرخطی برای استفاده بهتر از مواد الکترومغناطیسی کار کنند. این امر دستیابی به اتصالات شار سینوسی را با استفاده از تکنیک‌های بهینه‌سازی طراحی ماشین دشوار می‌کند [33] که به ناگزیر منجر به هارمونیک‌های گشتاور، جریان و ولتاژ می‌شود. به طور معمول، موج های گشتاور به طور دوره ای با موقعیت روتور در شش برابر فرکانس الکتریکی (هارمونیک مرتبه ششم) تغییر می کند.
