Overvoltage Analysis of 110 kV Transmission Line with Extra-length for Qinghai-Tibet Railway: Part Ⅳ- Resonant Overvoltage

摘要

The resonant Overvoltage of 110 kV Qinghai-Tibet 110-kV transmission line for the Qinghai-Tibet Railway is analyzed. All possible cases to generate parameter resonance are analyzed, and respective compensation countermeasures against the parameter resonance are discussed, the effective methods to avoid parameter resonance is put compensating capacitors with suitable capacity into operation.
