Abstract

To study transient electromagnetic characteristics of ultrahigh voltage controlled shunt reactors (CSRs) of thyristor controlled transformer type, a transient electromagnetic model for this CSR based on duality theory is proposed and implemented in PSCAD software. A 220 V single-phase prototype for this CSR is developed and tested. The transient winding currents and flux densities in different parts of the iron core are calculated under a changed conduction state of the thyristor pair using this model. The calculated results agree well with the experimental results. The transient electromagnetic characteristics of the CSR are analyzed.
