| 摘要: |
| 结合模态分析法和谐波潮流算法,基于C#和Matlab语言开发出一套谐波分析及谐振评估软件.除换一般的谐波分析功能外,软件还具有2个特色功能:通过频率扫描能搜索出系统中所有的谐振点,对谐振点进行模态分析,得到系统中发生谐振的严重区域,并以参与因子指标反映谐振在系统中的分布;对加入滤波器后的系统进行频率扫描,若系统谐振点次数与谐波源次数相近,则重新调整滤波器参数,经反复调整与扫描直至系统谐振点次数不与谐波源次数相近,实现滤波器参数的优化设计,解决由于其参数设计不恰当而引起的谐波谐振或谐波放大问题.算例仿真结果表明该方法对谐波谐振评估以及无源滤波器参数优化是正确、有效的. |

| Abstract: |
| Combined with modal analysis and harmonic power flow algorithm,the harmonic resonance analysis and assessment software is developed with C# and Matlab,which has,besides the general functions of harmonic analysis,two special features: all system resonances can be searched through frequency scanning,which are analyzed by modal analysis to find the serious harmonic resonance areas of power system and to represent their distribution with the participation factor index;the frequency scanning is carried out for t... |
