Elimination of Commutation Failure of VSC HVDC System with Controllable Capacitor
Journal Title: Elysium Journal of Engineering Research and Management - Year 2016, Vol 4, Issue 1
Abstract
This system presents a totally unique hybrid converter configuration for traditional Line-Commutated converter (LCC) HVDC technology aiming to eliminate commutation failures at lower place serious faults. Dynamic series insertion of capacitors throughout commutation is employed to increase the effective commutation voltage. The operational principles are bestowed followed by elaborate mathematical analysis for every zero ohmic resistance single-phase and three-phase faults thus on choose the required capacitance size and its voltage level. The performance of the planned technique is valid by simulation leads to Real Time Digital machine (RTDS) and so the results show that the planned convertor con- figuration is during a position to eliminate commutation failures below every fault cases. Consequently partial power transferring capability throughout single-phase fault and quick fault recovery from three-phase fault can be achieved. Additional simulation results show that the harmonic content of electrical convertor AC voltage and current are not significantly accumulated and so the voltage stress of the thyristor valve is harking back to that of the primary benchmark system.
