Modeling Surge Propagation in Machine Windings
نویسنده
چکیده
This paper describes a computer model for calculating the surge propagation in the winding of electrical machines. The model considers the winding as a combination of a multiconductor transmission line and a network of lumped parameters. The frequency dependence of the winding electrical parameters are calculated and incorporated into the analysis by means of Foster and Cauer circuits. Finally, this hybrid model is validated by a comparison of calculated and measured results inside a high voltage machine winding. Key-Words:Switching transients, surge distribution, winding electrical parameters, network synthesis.

Voltage Distribution of Internal Windings of Pole-Mounted Distribution Transformer by Lightning Surge and Measures for Voltage Reduction
When steep lightning surge enters a pole-mounted distribution transformer, the voltage distribution of the internal windings is unbalanced. It is known that a layer-to-layer short or a turn-to-turn short occurs where the voltage distribution of windings is high. In this paper, the voltage distribution of the windings was measured at the primary and secondary sides of the transformer using a tes...

The over-voltage phenomenon is usually described using the traveling wave and reflection phenomena in variable speed drive system. A voltage pulse, initiated at the inverter, being reflected at the motor terminals due to a mismatch between the surge impedance of the motor and the cable. In this paper, resistance, inductance and capacitance of the cable and the motor windings are obtained experi...
متن کاملInternal Protection of Transformer Windings Against Transeint Surges Using ZnO Varistors
Power system overvoltages due to switching, lightning and other disturbances are the main problem for designers of the power transformers. Once some frequencies of the incoming surges match with some of the natural frequencies of transformer winding, the resonance phenomenon is expected in transformer winding. The resonant overvoltages may destroy the insulation between turns and cause to insul...

متن کاملDynamic Modeling and Analysis of Wind Turbine Driven Doubly Fed Induction Generator
Abstract— The doubly-fed induction machine used as a wind turbine generator has recently received a great attention from the industrial and scientific communities. The reason is twofold: first, this machine easily produces a fixed frequency voltage from the stator windings when the rotor is driven at variable speed; second, the excitation power electronics converter feeding the rotor windings n...
