Simulation and Analysis of Ferroresonance in Power System
Ferroresonance is a nonlinear dynamic phenomenon, between a non-linear inductor and system capacitance. Hereby a study is undertaken on systems comprising of the required parameters, under which the possibility of ferroresonance may arise. For any operating voltage applied to series combination of capacitance and transformer windings at no-load, the critical value of capacitance to cause ferror...

The author is with the System Planning Department, Manitoba Hydro, 121146 Waverley Street, P.O. Box 815, Winnipeg, Manitoba, R3C 2P4, Canada (e-mail: [email protected]). Abstract—Catastrophic equipment failures continue to occur today due to ferroresonance even though this phenomenon has been extensively studied over the past ninety years. This paper is concerned with describing practical ...
متن کاملFerroresonance Phenomenon in Power Transformers - Experimental Assessment
This paper reports on the results of recent research and development efforts to study and assess various impacts of ferroresonance phenomenon on operating performance of power transformers and to investigate ways to mitigate the effects of such phenomenon. Three-phase core-type transformers are used in the study. The results of the technical investigation and the associated ferroresonance exper...
متن کاملFerroresonance in Power and Instrument Transformers
This chapter describes the fundamental concepts of ferroresonance phenomenon and analyzes its symptoms and the consequences in transformers and power systems. Due to its nonlinear nature, the ferroresonance phenomenon can result in multiple oscillating modes which can be characterized based on the concepts of the nonlinear dynamic systems, e.g., Poincare map. Among numerous system configuration...
متن کاملwind farm impact on generation adequacy in power systems
در سال های اخیر به دلیل افزایش دمای متوسط کره زمین، بشر به دنبال روش های جایگزین برای تامین توان الکتریکی مورد نیاز خود بوده و همچنین در اکثر نقاط جهان سوزاندن سوخت های فسیلی در نیروگاه های حرارتی به عنوان مهم ترین روش تولید توان الکتریکی مطرح بوده است. به دلیل توجه به مسایل زیست محیطی، استفاده از منابع انرژی تجدید پذیر در سال های اخیر شدت یافته است. نیروگاه های بادی به عنوان یک منبع تولید توان...
