Abstract

Power electronics and other similar components can generate harmonic voltages and currents in power systems. Harmonic voltages will produce heat in insulating materials and then cause further aging of insulation. Different harmonic voltages may be produced by fire angle variation of a typical FACTS component. Imposed harmonic voltages from network also can cause aging of insulation. In this paper we study life assessment of a SVC capacitor with thyristor fire angle variation when we have voltage harmonic injection from network and automatically unusual aging is valid
