Abstract :
A dynamic mathematical model-Johns arc model which could be used to simulate the dynamic secondary arc in the process of single-phase auto-reclosure after transient single-phase faults is presented and actualized in PSCAD/EMTDC. This model is used in the digital faults simulations of the first ultra high voltage (UHV) transmission line of 1000 KV class in China-the Jindongnan-Jingmen UHV single circuit transmission project under construction, the outcomes and influences of several known important factors, such as wind, manner of shunt compensation and other meteorological and geographical factors including temperature, humility, altitude and so on are discussed. According to the discussion, the preconcert reclosure interval of 1s is proved to be proper.
