Thyristor-Controlled Series Compensation (TCSC) is used in power systems to dynamically control the reactance of a transmission line in order to provide sufficient load compensation. The benefits of TCSC are seen in its ability to control the amount of compensation of a transmission line, and in its ability to operate in different modes. These traits [...]

FACTS: Series Compensation
Posted in Electrical Engineering, tagged Power Systems, FACTS, Economics, Electrical Engineering, Engineering, Infrastructure on 30 October 2009 | Leave a Comment »
The main purpose of series compensation in power systems is to decrease the reactive impedance of the transmission line to reduce voltage drop over long distances and to reduce the Ferranti effect. By adding series capacitors to the line, engineers can compensate for the physical inductance inherent in the transmission line. The voltage drop across the [...]
FACTS: Basic Concepts – Thyristors
Posted in Electrical Engineering, tagged Power Systems, FACTS, Electrical Engineering, Engineering on 23 October 2009 | Leave a Comment »
The development of high-power thyristors and Insulated Gate Bipolar Transistors (IGBT) enabled the cost-effective provision of FACTS devices. The actual behaviour of these devices is beyond the scope of this article, but on a basic conceptual level, they are simply fast acting switches, controlled by some external means (a trigger). Triggers can be either electric [...]
