The Simulation In Research On Ferroresonance In Grounded Neutral Point

Ferroresonance is an over-voltages always occurs in neutral isolated distribution, and sometimes occurs in high-voltages network. Aim at the 110Kv network, the real network is simulated, analyzed and compared in this paper. Finally, the approach of trapezium is selected as one of the best methods. To the neutral grounded system, this paper combines the arithmetic theory and the power model, selects the proper parameters, uses the software of calculation and simulation, analyzes the result of the simulation, and not only brings forward a new method of mitigation, but also provides the methods of mitigation ferroresonance under the different situation at last. The research of ferroresonance has the practical value of fault analysis and controls in the power system.Wang Xiaoyun(Theoretical Electrical Engineering and New Technique)Directed by Prof.Li Baoshu...
