مسئله ی پایداری سیستم های قدرت و دمپینگ موثر نوسانات فرکانس پایین یکی از مهمترین مسائل مورد توجه مهندسان برق در شبکه های قدرت می باشد. پایدارسازهای سیستم قدرت، روش های ترکیب ان ها با avr و نیز انتخاب و تصحیح پارامترهای pss به طور گسترده ای در مقالات مختلف بررسی شده است. هدف عمده ی این پایدار سازها دمپینگ موثر و به موقع نوسانات شبکه های قدرت می باشد. در حوزه ی طراحی pss وتنظیم پارامترهای ان روش ...

This study concerns numerical simulation, modeling and optimization of aerodynamic stall control using a synthetic jet actuator. Thenumerical simulation was carried out by a large-eddy simulation that employs a RNG-based model as the subgrid-scale model. The flow around a NACA0015 airfoil, including a synthetic jet located at 10 % of the chord, is studied under Reynolds number Re = 12.7 × 106 a...

In this study, a new method for designing the damping controller was proposed to improve the transient power system stability in a single machine network connected to an infinite bus. The STATCOM controller problem in a wide area of the system function was considered as an optimization problem with multi-purpose objective function. Also, the Honey Bee Mating Optimization Algorithm was used to d...

In many industries, manufacturers─for various reasons─have to collect products that have been used by customers. Then, depending on the status of the returned products, appropriate decisions are made to process the products. In this paper, issues such as inventory control and product planning optimization in the environment of integrated reverse logistics have been focused on. The assumed logis...
