Abstract

According to the intrinsic characteristics of the back-to-back HVDC transmission system

this paper analyzes how to determine the smoothing reactors steady rating and transient rating of back-to-back HVDC transmission system

including the selection and calculation of harmonic voltage source parameters related for calculating smoothing reactor steady rating

the construction of simulation circuit for calculating smoothing reactor steady rating

the faults which could happen of smoothing reactors for back-to-back HVDC transmission system and the methods for calculating smoothing reactor typical faults. This paper takes Yunnan power grid and southern power grid asynchronous link Luxi back-to-back HVDC transmission project as an example

calculates the steady rating and transient rating of smoothing reactors

and determines the insulation level of smoothing reactors.
