Abstract

A frequency domain model of a thyristor controlled reactor (TCR) developed using a transfer function based analysis is described. The model linearises the relationships between the current spectrum generated by a TCR and the terminal voltage and firing angle distortions. The relationships are expressed in the form of direct algebraic equations which are verified by dynamic simulation. The frequency dependent admittance of a TCR is developed and also verified. The model provides for a fast and accurate method for the analysis of both integer and noninteger harmonic interactions around a TCR
