In order to reduce the unbalance vibration of the rotating machinery automatically during the work process, a new type of liquid-transfer active balancing system was proposed. In the system, a balancing disc divided into four liquid storage chambers was mounted on the rotor. When the unbalance response of the rotating machinery was higher than the limiting value, compressed air was injected to ...
Rotating machinery, including machining spindles, industrial turbomachinery, and aircraft gas turbine engines, are very commonly used in industry. One major problem faced by these machineries is the harmful, imbalance-induced vibration. Many methods have been developed to reduce this vibration: o!-line balancing methods [1], on-line active balancing methods using mass redistribution devices [2}...
To eliminate the influence of the inconsistency on the cycle life and the available capacity of the battery pack, and improve the balancing speed, a novel inductor-based layered bidirectional equalizer (IBLBE) is proposed. The equalizer is composed of the bottom balancing circuits and the upper balancing circuits, and the two layer circuits both consist of a plurality of balancing sub-circuits,...
This dissertation presents voltage stabilization techniques for flying capacitors used in soft-switching multilevel active power filters. The proposed active filter has proved to be a solution for power system harmonics produced by static high power converters. However, voltage unbalance of the clamping capacitors in the active filter in practical applications was observed due to its unequal pa...
This paper first presents a simple control technique for active filters to compensate current harmonics and reactive power of nonlinear loads. This method is usable for both single –phase and three –phase systems. Then a new method for load balancing and reactive power compensation for unbalanced sinusoidal load currents is presented. Finally by combination of two methods an active filter contr...
تولید یک مدل مناسب در حل منظم مسئله وارون به انتخاب مناسب پارامتر منظمسازی وابسته است، لذا برآورد این پارامتر میتواند اهمیت زیادی داشته باشد. در اکثر مسائل وارون، این پارامتر بهصورت تجربی انتخاب میشود. هدف از تحقیق حاضر، عرضه و بهکارگیری روشی برای انتخاب خودکار پارامتر منظمسازی مناسب برای وارونسازی دوبُعدی دادههای مگنتوتلوریک است. برای این منظور دو روش اعتبارسنجی تقاطعی تعمیمیافته (GC...
