| 摘要: |
| 提出一种模糊目标函数优化方法，并将其应用到电气化铁路综合有源补偿装置输出滤波器的优化配置，致力于解决电气化铁路综合有源补偿装置引起的高次谐波污染问题。根据工程实际情况，建立LC输出滤波器简化模型，提出了在常用LC输出滤波器的滤波电容上串联电阻和电感的并联支路来对LC输出滤波器进行改进。建立以满意度为综合指标的模糊优化目标函数，采用加权多目标方法进行寻优。最终实现对输出滤波器的参数进行优化设计。仿真分析充分论证了所提出的改进算法及模型是正确可行的。 |

| Abstract: |
| Fuzzy objective function optimization is proposed and applied to the output filter configuration for the integrated active compensation equipment of electric railroads to suppress the higher-order harmonics pollution. The simplified model of LC output filter is established. It is put forward to improve the normal LC output filter by connecting in series to the filter capacity a parallel circuit of resistor and inductor. With the satisfaction as the integrated index，the fuzzy objective function is established and the weighted multi-objective optimization is applied to obtain the optimized LC parameters. Simulative analysis verifies the correctness and feasibility of the proposed improved algorithm and model. |
