Abstract :
The use of a phase independent thyristor-controlled reactor (TCR) compensator to balance asymmetrical loads is a well-known subject. However, if the control strategy is based on balanced supply voltage conditions and if this does not occur the required compensation may fail or it can exhibit inaccuracy. A new formulation to evaluate the necessary TCR phase susceptances under unbalanced voltage conditions is proposed. By using this technique, computational investigations and practical discussions are carried out to establish a comparison to the classical method results. The discrepancies between the two approaches with reference to the degree of asymmetry are highlighted
