 the power flow control capability inherent with HVDC Light, however, avoids having the thermal
loading on just one circuit, effectively limiting the net transfer capability.  Examples of large
disturbances are the loss of a whole power plant or failure of a major transmission line.

 The Series Capacitor reduces the total reactance of a transmission line and thus makes the line
electrically shorter. To summarize, the main reasons for incorporating series capacitors in
transmission systems will be: ,To increase the power transfer capability as a result of

of more stringent planning crite- ria, and the need to maximize transfer capabilities.
