Static VAr compensators with thyristor-controlled reactors generate harmonics. Due to the voltage regulation characteristics of the compensator, the generated harmonics depend on unknown thyristor firing angles and the network load flow conditions. The inclusion of load flow dependent firing angle determination in the author's computer-based multiphase harmonic load flow (MHLF) technique (see ibid., vol.6, no.1, p.174-82, 1991) is described. It uses a novel conduction angle adjustment scheme. This general and simple scheme can easily be used for the analysis of other nonlinear elements with control characteristics. Various case studies are presented to demonstrate the performance and application of the technique. Field test comparisons are included
