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:: The mechanical data of turbines and a generator of 1000 MW reference unit, working at overcritical parameters, were established. Using the modal method, the characteristic frequencies of torsional oscillations in shafts of rotating masses were calculated. The values of torsional torques in shafts which can arise during faults in electrical networks, like close distance short-circuits, the action of automatic reclosing, synchronization, as well influence of electromagnetic torques from the network side causing the resonance oscillations of unit were investigated.

Opis:: This paper presents the method of calculation of the electric and magnetic fields under overhead transmission line with any number of circuits, phase positions, voltages and current loads. Calculations of this type usually require specialized and costly programs. The program EMTP/ATP is a royalty free tool to calculate the electric transient and steady states in complex power systems. You can use this program and through appropriate modeling the multi-phase wire system representing the line and measurement device calculate the strength of the electric and magnetic fields. The results of calculations are characterized by a very small error compared to the results obtained by using the specialized commercial program. This method can be used with other popular engineering tools like Matlab/Simulink or PSCad.
