Study on fault simulation of HVDC system based on PSCAD/EMTDC

摘要

The model of high voltage direct current (HVDC) system was built with the electromagnetic simulation software PSCAD/EMTDC, and then simulative analysis of stable operation state and faulty operation state was carried out on this the model, which gives simulated waveforms and conclusion analysis. This paper provides the effectiveness of the HVDC system of PSCAD/EMTDC and the basis system of HVDC for future fault diagnosis according to the result of simulation is consistent with that of therapy.
