摘　　要：在直流输电工程设计过程中,交流系统等值和背景谐波计算是一个必不可少的环节,为克服目前使用的电力系统分析程序交流全频等值和谐波分析功能的问题,研发了基于PSS/E和BPA数据格式的文件研发全频段交流系统等值和背景谐波计算程序。该程序利用PSS/E或BPA的数据文件,建立元件在谐波频率下的数学模型;采用单一频率下正弦稳态网络的节点分析法,扫描计算交流系统的等值阻抗和背景谐波。同时,利用电磁暂态仿真软件PSCAD/EMTDC对程序得到的结果进行验证,结果非常吻合。故该全频段交流系统等值与谐波计算程序可为国内直流输电工程设计提供有用的工具。In order to facilitate AC system equivalence and harmonic calculation, which are very essential in the analysis and design of HVDC transmission system, a new program for AC system wide frequency range equivalence and background harmonic calculation based on PSS/E and BPA data files is presented in this paper. The program establishes component harmonic models from the ＊ . raw file of PSS/E and ＊ . DAT and ＊ . SWI files of BPA, scans the equivalent harmonic impedance of AC system and calculates the background harmonics. Then these results are very close to those provided by PSCAD/EMTDC software. Therefore, this new program can be a useful tool for the design of HVDC transmission systems.
