Harmonic domain representation of thyristor controlled reactors

A new TCR (thyristor controlled reactor) model has been developed by linearising the state equations of the TCR in the harmonic domain. The resulting equations can be interpreted as a harmonic Norton equivalent. They can also be represented in the multiphase harmonic domain frame of reference, where they could combine easily with the frequency dependent admittances of the transmission network and with other linearised components such as saturated transformers, rotating machinery, electric arcs and power convertors. The linearised TCR model is completely general. It is suitable for assessing TCR filtering equipment requirements and for harmonic penetration studies
