Opis:: Zjawisko występowania drgań ferrorezonansowych w systemie elektroenergetycznym jest istotnym problemem w elektroenergetyce. W artykule przedstawiono badania symulacyjne możliwości wystąpienia ferrorezonansu w sieci 110 kV.
The ferroresonance phenomena in the power system is a significant problem in electric grid. The nonlinear vibration of the current and the voltage present a risk to the electrical apparatus. Due to the nonlinearity of that phenomena a classical analysis method are not applicable and digital methods of analysis are necessary. The article present a risk to the electrical apparatus. Due to the nonlinearity of that phenomena a classical analysis method are not applicable and digital methods of analysis are necessary. The article presents application of the EMTP-ATP program to determine simulation results. EMTP-ATP is a universal program system for digital simulation of transient phenomenon of electromagnetic. To analysis was subjected the 110kV double-circuit overhead lines with two different nonlinear elements – power transformer and voltage transformer. That types of circuit is one of the susceptible to ferroresonance oscillations. Computer simulations confirmed that theory. The oscillation were observed for the given configuration. The results of the simulation shows that a voltage transformer are particularly vulnerable to ferroresonance phenomenon.

Opis:: The calculations of electrical network susceptibility of chosen 110 kV, 220 kV and 400 kV networks to ferroresonance occurrence, its type and parameters were performed in the study. The influence of such parameters as voltage transformer (VT) magnetization characteristic, equivalent network capacitance, and the breaker grading capacitance on ferroresonance was investigated. The calculations were performed using the EMTP/ATP program. Some of the results were presented in this paper.

Opis:: Arresters are widely used in power systems to protect other equipment against overvoltages. However, in some conditions, they can’t operate successfully. One of the disturbances leading to the failure of the riser pole arresters is the ferroresonance overvoltages. In this paper, at first the influence of different transformer simulation models of ATP software on the occurrence of ferroresonance is studied and then the effect of ferroresonance on the riser pole arrester has been scrutinized through the thermal and electrical performance of the arrester in an underground distribution system. The results show that the arrester temperature rises due to energy dissipation in a ferroresonance circumstance, which indeed may result into the explosion of the arrester. Also, applying different models of the transformer in the ATP software and comparing the results, it is shown that the available models do not show the same effect on the arrester.

Opis:: Ferroresonance is a phenomenon usually initiated by transients in power networks resulting from e.g. switching operations or ground faults. Non linear behavior of the core of an inductive voltage transformer results in magnetic saturation. long-lasting ferroresonant state is dangerous to the equipment due to prolonged overvoltage and large overcurrents in HV windings.in the present article numerical simulations of the ferroresonance phenomenon in a HV inductive Vare presented. the ferroresonant oscillations analyzed result from interaction between the voltage transformer and a grading capacitance of a circuit breaker.
