摘　　要：根据背靠背高压直流输电系统的固有特点,研究分析了如何仿真确定背靠背高压直流输电系统平波电抗器的稳态额定值和暂态额定值,其中包括:用于计算平波电抗器稳态额定值的谐波电压源相关参数的选取与计算;用于计算平波电抗器稳态额定值的仿真回路的搭建;背靠背高压直流输电系统平波电抗器可能发生的故障以及用于计算平波电抗器典型故障的方法。以云南电网与南方主网鲁西背靠背直流异步联网工程为例,对平波电抗器稳态额定值和暂态额定值进行了仿真和计算,并对平波电抗器绝缘水平进行了确定。According to the intrinsic characteristics of the back-to-back HVDC transmission system, this paper ana- lyzes 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 asyn- chronous 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.
