Abstract

This paper develops an accurate and general stability model for the ASC (thyristor controlled reactor). The model is valid for both the capacitive and inductive regions of the ASC operation. It is accurate in that the instantaneous voltage and current waveforms and also the fundamental component of the capacitor voltage (needed for stability) are determined every half-cycle by solving the differential equations of the ASC circuit. The model is capable of incorporating any control algorithms. The validity of the model is demonstrated by comparing the model with the Electromagnetic Transient Program (EMTP) digital simulations using step time of 10 μs
