bibo:abstract
  • This paper describes a study of transient characteristics in 765㎸ untransposed transmission lines. As the 765(㎸) system can carry bulk power, some severe fault on the system may cause large system disturbance. The large shunt capacitance and small resistance of 765㎸ transmission line make various difficulties for its protection. These problems including current difference between sending and receiving terminals on normal power flow, low order harmonic current component in fault current and current transformer saturation due to the long DC time constant of the circuit etc. must be investigated and solved. The analysis of transient characteristics at sending terminal has been carried out for the single phase to ground fault and 3-phase short fault, etc. The load current, charging current in normal condition and line flows, fault current, THD(Total Harmonic Distortion) of harmonics, time constants have been analysed for the 765㎸ untransposed transmission line systems.
