Abstract :

Submodule overcurrent caused by DC pole-to-pole fault in modular multilevel converter HVDC MMC-HVDC system is one of the important research objects about its electrical characteristics. In this paper, the fault mechanism before and after the converter blocked was analyzed respectively and the circuit model for the analysis of submodule overcurrent was explored. The analytic equation for overcurrent calculation was deduced and a detailed analysis was also performed. The changes of submodule overcurrent stress with different circuit parameters were obtained and the key issues were also summed up. The results indicate that the submodule overcurrent is the AC system three-phase short-circuit current superposed the discharging current before the converter blocked, and the submodule overcurrent is the AC system three-phase short-circuit current superposed the valve reactor freewheeling current after the converter blocked. From the computation and simulation results, it is concluded that the analytical method is feasible and its calculation results are comparatively precise. by Mohd Liaqat ""Modelling and Operation of HVDC Based Power Transmission System"" Published in International Journal of Trend in Scientific Research and Development (ijtsrd), ISSN: 2456-6470, Volume-3 | Issue-2 , February 2019, URL: https://www.ijtsrd.com/papers/ijtsrd20319.pdf Paper URL:https://www.ijtsrd.com/engineering/electrical-engineering/20319/modelling-and-operation-of-hvdc-based-power-transmission-system/mohd-liaqat
