in this paper power system stability enhancement through static synchronous compensator (statcom)based controller is investigated. the potential of the statcom supplementary controllers to enhance thedynamic stability is evaluated. the design problem of statcom based damping controller is formulatedas an optimization problem according to the eigenvalue based objective function that is solved by...
This paper presents a complete nonlinear model for a wind turbine system with a variable speed cage machine generator, firstly. Then a primary controller which is named “reference signal generator” will be designed to lead system to optimum operating condition at various wind speeds. Regulating terminal voltage of generator, increasing generator efficiency and maximum power tracking...
The paper is devoted to solution of some problems in nuclear power station generating unit intellectual control systems using genetic algorithms on the basis of control system model development, optimizations methods of their direct quality indices and improved integral quadratic estimates. Some mathematical vector models were obtained for control system multicriterion quality indices with due ...
در این پروژه ابتدا معادلات مدل کلی یک ماشین سنکرون که مدل روتور آن دارای n مدار روی محور d و m مدار روی محور q می باشد را بصورت ماتریسی بدست آورده و روش جدیدی برای بیان کردن اشباع شار اصلی در مدل ماشین سنکرون به منظور شبیه سازی پایداری گذاری سیستم قدرت ارایه می نماییم. این روش بجای استفاده از اندوکتانسهای مغناطیسی اشباع شده برای بیان اشباع از جریان های کمکی و اندکتانسهای مغناطیسی غیر اشباع استف...
Power system blackouts have become a serious problem for electric utilities especially in recent years. Different forms of system instability have emerged in recent blackouts, such as voltage instability and frequency instability. To counteract each form of system instability, special algorithms have been designed in the protection system, e.g. Under Frequency Load Shedding (UFLS) and Under Vol...
The proposed paper presents the DC/AC microgrid modeling using the Energy storage units and photovoltaic (PV) panels. The modal consists of a two stage power conversion. The power is supplied to the both DC and AC loads by this PV solar panels. The suitable way to explore the PV generation model is by using manufacturer datasheet. A bidirectional converter is connected to the battery storage sy...
