摘　　要：线路高抗的容量配置直接决定了系统安全稳定运行。配置高抗容量时,需要进行操作过电压、潜供电流、自励磁的校验。本文开展了高抗容量配置的自励磁校验技术研究,提出了高抗容量配置的特征根校验方法,与目前充电容量校验方法进行了详细比较,物理概念清晰,理论严谨,计算准确,为高抗容量配置自励磁校验、黑启动过程自励磁计算提供了技术支持。The capacity configuration of the line reactor directly determines the safe and stable operation of the system.When line reactor capacity configuration is carried out,it is necessary to check the operating overvoltage,latent supply current and self-excitation.This paper carries out a technical study on the self-excitation calibration of line reactor capacity configuration,proposes the characteristic root calibration method of line reactor capacity configuration,and makes a detailed comparison with the current charging capacity calibration method.The physical concept is clear,the theory is rigorous,and the calculation is accurate,which provides technical support for the self-excitation calibration of reactor capacity configuration and the self-excitation calculation of the black start process.
