Abstract :
Several main factors influencing the transmission capability of EHV/UHV AC lines are discussed, including synchronous stability, voltage and reactive power control, series compensation and shunt compensation. A short circuit ratio for AC transmission systems is proposed in this paper, which accurately describes the influence of the two end systems upon the transmission capability. From the above analysis, a set of curves reflecting the relationship between the transmission capability and the transmission distance is developed, which can be used in electric power system planning and design.
