در این رساله، سه بحث شناسایی، کنترل و جایابی بهینه کنترل کننده های نامتمرکز در سیستم های ابعاد بزرگ بررسی می گردند. در بحث شناسایی، روشی برمبنای تکنیک h? جهت شناسایی سیستم های ابعاد بزرگ غیرخطی افاین پیشنهاد شده است. شرط اعمال شده جهت معتبر بودن روش اینست که یا تمام حالت های سیستم قابل اندازه گیری باشند یا بتوان با استفاده از تخمین بعضی سیگنال ها، تخمینی از سایر سیگنال ها را به صورت لحظه ای به...
in this paper optimal torque control (otc) of stand-alone variable-speed small-scale wind turbine equipped with a permanent magnet synchronous generator and a switch- mode rectifier is presented. it is shown that with otc method in standalone configuration, power coefficient could be reached to its maximum possible value, i.e. 0.48. an appropriate control algorithm based on turbine characterist...

The main goal of this paper is to study statistical indices and evaluate AGC indices in power system which has large penetration of the WTGs. Increasing penetration of wind turbine generations, needs to study more about impacts of it on power system frequency control. Frequency control is changed with unbalancing real-time system generation and load . Also wind turbine generations have more flu...
In this paper, the performance of two types of FACTS devices in order to enhance the power system static voltage stability has been investigated. These devices include Static Var Compensator (SVC) and Thyristor Controlled Series Capacitor (TCSC). The modeling of the Single Machine Infinite Bus (SMIB) and aforesaid devices has been made up in steady state mode with disregarding of the generator ...
any change in the refractive index of a laser active medium can lead to serious degradation of beam quality, laser beam modes, laser performance and variation in the intensity distribution. alteration in the refractive index of laser active medium is especially notable in high power lasers. it is clear that in the laser beam production, the pumping agent induces a great amount of heat which...
