【Abstract】 Aiming at the fixed series capacitor compensator( FSCC) installing on the extra-high voltage transmission line,first of all,This paper analyzed the structure characteristics of the FSCC and illustrated the principle of increasing the power transmission and improving the power system stability by using the FSCC. Secondly,the breakvariable situation of transmission line impedance parameters influenced by FSCC were analyzed,what’s more,the distance protection and zero sequence protection relying on system impedance parameters are also discussed. At last,some effective methods are presented to resolve the influences of the FSCC on the relay protection performances.更多还原
