The Impact Study of a Statcom on Commutation Failures in an HVDC Inverter Feeding a Weak AC System

The Impact Study of a Statcom on Commutation Failures in an HVDC Inverter Feeding a Weak AC System The Static Synchronous Compensator (STATCOM) devices are pure power electronics devices that use voltage source, IGBT, IGCT or GTO based converters to generate reactive current. This paper illustrates the effect of STATCOM connected whit an HVDC inverter feeding a weak AC network, on the recovery from commutation failures following AC side disturbances. MATLAB/SIMULINK simulation results have demonstrated the robust performance of the proposed system based on the first CIGRÉ HVDC Benchmark model against commutation failures.
