Performance Analysis Of SSSC Based On 48 Pulse VSC

This paper describes an active approach to series line compensation in which a synchronous voltage source implemented by a gate-turn-off thyristor (GTO) based Voltage-sourced inverter, is used to provide controllable series compensation. This compensator called static synchronous series compensator (SSSC) can provide controllable compensating voltage. Static synchronous series compensator (SSSC) for the control of reactive power flow on transmission line and its effectiveness through multi-pulse inverters is observed. The SSSC is based on injecting a voltage in given line to counter the voltage drop produced by the inductive reactance of the line. The resulting transmissionline emulates the control of transmission line reactance and assists in controlling the power transmission capability. For analyzing the performance of the SSSC inserted in series with the line a single machine infinite bus power system (SMIB) has beenconsidered. SSSC based on 48-pulse voltage source inverter is presented. Simulation of 6, 12, 48 multi pulse converter topologies using PSCAD Version 4.2 has been performed. Harmonic analysis is compared for the above. The performance of SSSC with faults like LLL-G and L-G are done. It has been found that the power transfer capability is enhanced by using SSSC
