Simulation Study on Anomalous Commutation Failure in Multi-Infeed HVDC Systems

Abstract:

Commutation failure theory in HVDC transmission system is proposed and its reason is analyzed. Anomalous commutation failure phenomenon related to concurrent CF or successive CF in multi-infeed HVDC transmission system is presented. Six kinds of ac system strength are used in simulating the anomalous commutation failure, and the results show that this phenomenon is more and more serious at first as the system strength increases, and then become less serious as the strength becomes stronger. The reason of anomalous CF is found when analyzing phase A voltage with Fourier analysis in one period after fault, that is because of the major dc components and the low-order harmonics existing in voltage waves.
