پروژه تاثیر کنترل کننده های FACTS برروی پایداری سیستم های توان متصل با مولدهای القایی با تغذیه مضاعف توسط MATLAB
شبیه سازی مقاله Impact of FACTS controllers on the stability of power systems connected with doubly fed induction generators
چکیده انگلیسی:
The increasing power demand has led to the growth of new technologies that play an integral role in shaping the future energy market. Keeping in view of the environmental constraints, grid connected wind turbines are promising in increasing system reliability. This paper presents the impact of FACTS controllers on the stability of power systems connected with wind energy conversion systems. The wind generator model considered is a variable speed doubly fed induction generator model. As power systems became interconnected, areas of generation were found to be prone to electromechanical oscillations. These oscillations have been observed in many power systems worldwide. As the level of power transmission rose, largely through existing interconnections, which were becoming relatively weak and inadequate, load characteristics added to the problem causing spontaneous oscillations. The dynamic simulation results yield information on (i) the impact of faults on the performance of induction generators/wind turbines, (ii) transient rating of the FACTS ontrollers for enhancement of rotor speed stability of induction generators and angle stability of synchronous generators. EUROSTAG is used for executing the dynamic simulations.
نتیجه گیری انگلیسی:
The development of wind turbine and wind farm models is vital because as the level of wind penetration increases it poses dynamic stability problems in the power system. For the present work we have taken a doubly fed induction generator model and illustrated the presence of sustained oscillations with wind farms. Suitable Flexible AC Transmission Systems controllers are modeled using the non-linear simulation models and the transient ratings of the FACTS controller are obtained to stabilize the rotor speed/rotor angle oscillations in a DFIG based wind energy conversion scheme.
