A Novel Active Suppression Method For Secondary Arc Current Of Half-Wavelength Ac Transmission
IECON 2017 - 43RD ANNUAL CONFERENCE OF THE IEEE INDUSTRIAL ELECTRONICS SOCIETY(2017)
摘要
Half-wavelength AC transmission (HWACT) possessed economic advantages due to its characteristics. However, the problem of secondary arc current limits its development and application. The neutral reactor is not suitable for HWACT and high speed grounding switch (HSGS) has many drawbacks. In this paper, the characteristics of secondary arc current in HWACT are studied in detail. Then, active suppression method for HWACT secondary arc current is proposed, which is based on a converter. Simulation study in PSCAD/EMTDC is carried out to provide its theory feasibility. The simulation results show that the proposed method is able to limit secondary arc current, speed up the arc extinction and improve the system's fault recovery efficiency in HWACT.
