| 摘 要： | 本文进一步发展和完善了作者开发的交直流(AC/DC)系统通用数字仿真程序,并在此基础上应用快速傅立叶变换(FFT)方法开发了AC/DC系统谐波分析程序。该程序既可分析稳态谐波,又可分析各种复杂条件下的暂态谐波。针对某一实际直流输电系统在交流不对称故障时的暂态谐波特性进行了示例性分析计算.

ANALYSIS OF DYNAMIC HARMONICS IN HVDC SYSTEMS |
| |
| Abstract: | The versatile digital simulation program for AC/DC power systems developed by the authors is expanded and perfected, and on the basis of above, an AC/DC system harmonic analysis package is developed by using FFT. This package can analyse not only steady harmonics but also dynamic harmonics in various kinds of complicated conditions. As an example, the characteristics of dynamic harmonics of a practical HVDC system under AC unbalanced faults are computed and analysed. |
