Abstract: The main circuit of the thyristor controlled series capacitor (TCSC) consists of a capacitor bank connected in series with the transmission line and a thyristor controlled reactor connected in parallel with the capacitor bank. To determine the parameters of capacitor banks and reactors used in TCSC, they must be designed with consideration not only of purpose and necessity but also manufacturing and economics. This paper deals with the parameter selection method for effective TCSC design based on practical examples. TCSC was selected as the case for analysis for the first time in Korea. Capacitance and inductance, the main circuit design factors, were calculated according to the installation purpose. Based on these, the number of stacks and operating losses of the thyristors considered safety were analyzed. The results of this study can be effectively used for TCSC main circuit design.
