Abstract

© 2017 IEEE. Nowadays, there is a considerable presence of power electronic devices in the power systems and it is expected that their use will continue growing with the implementation of renewable energy sources, HVDC (High voltage direct current) systems, among other applications. In the case of transformers, they can be connected to electronic converters in applications such as subsea gas compression systems, petroleum extraction and mining, and wind farms. Due to the fast commutation of the semiconductor switches, the electronic converters produce highly repetitive front pulses that will have an impact on the transformer's insulation system. In this paper simulations of continuous and interleaved transformer windings excited by a PWM (Pulse width modulation) voltage waveform are performed in order to analyze the stress produced by this type of excitation on transformer windings. The inter-turn and inter-disc voltages are computed to identify how the stress magnitude and distribution are affected by the use of interleaved winding techniques.
