Reduced harmonic state space model of TCR

This paper presents a harmonic state-space model of a three-phase thyristor controlled reactor. In this description, both the transient and steady-state response of individual harmonics are quantified. The results were validated using a strictly time-domain simulation. A further development of the model is the use of characteristic harmonics of the power converter to reduce the number of harmonics incorporated into state-space equations; this development effectively reduces computational burden.
