Abstract :
This work deals with the application of thyristor controlled series capacitors (TCSCs) suitably rated for radial distribution circuits. The various problems existing on long distribution lines that can be alleviated by the connection of variable series compensation, as a TCSC provides, are discussed. An important feature is the capability of the TCSC to operate as a short circuit current limiter. Thus, sensitive loads connected to nearby substations will not experience any voltage sags caused by faults on the distribution line where the TCSC is connected. The benefits of the connection of a TCSC on a radial distribution system are verified by means of the electromagnetic transients for DC (EMTDC) simulation package.
