Linearized harmonic domain model for three-phase thyristor controlled reactor

摘要

This paper presents a linearized harmonic domain model developed as a small-signal frequency transfer matrix of a three-phase thyristor controlled reactor (TCR). The transfer from the supply voltage to the reactor current is analyzed as separate effects produced from two causes, namely: (1) change in AC voltage; and (2) change in thyristor switching instant which allows controls to be modelled. The model is implemented as a tensor matrix and validated with results obtained from a time-domain simulation. This model is an important advance towards the development of a full harmonic state-space model of a TCR.
