Simple Optimizing Method of Shunt Reactor Connected to Double Circuit UHV Transmission Line for Minimizing Maximum Secondary Arc Current
On UHV transmission line, it is known that the secondary arc extinction time after clearing fault arc will be long and there is a possibility of auto-reclosing failure. Connecting shunt reactors with a neutral reactor to the transmission line is one way to reduce the secondary arc extinction time. D...

Zusammenfassung: | On UHV transmission line, it is known that the secondary arc extinction time after clearing fault arc will be long and there is a possibility of auto-reclosing failure. Connecting shunt reactors with a neutral reactor to the transmission line is one way to reduce the secondary arc extinction time. Double circuit transmission line requires consideration of inter-circuit capacitance as well as inter-phase capacitance, which causes difficulty in configuring optimal shunt reactor. This paper proposes a simple method optimizing the shunt reactors connected to the double circuit transmission line. |
