中文摘要:
      研究静止同步补偿器中并网侧电流谐波抑制器的技术问题,主要研究了静止同步补偿器基于L型谐波抑制器与LCL型谐波抑制器下的设计方法,并结合Matlab的伯德图分析方法分别对这2种谐波抑制器中各参数对谐波抑制的性能进行了研究;同时在保持总电感量相同的情况下,对这2种谐波抑制器的效果进行了对比研究,发现LCL型谐波抑制器有着显著的优势;搭建了静止同步补偿器系统仿真模型进行了仿真对比验证;最后通过基于DSP的无功补偿实验平台进行试验并对试验电流波形进行FFT分析,验证了上述理论分析的正确性和有效性.
英文摘要:
      The technology of grid-connected harmonic current suppressor in STATCOM system was introduced and the design methods of L type and LCL type harmonic current suppressor was studied. The effect of each parameter variation was analyzed, which affect the performance of L type and LCL type harmonic current suppressor based on bode diagram method of Matlab. At the same time, on the condition of maintaining the same value of the total inductance, the contrastive analysis on the performance of L type and LCL type harmonic current suppressor was studied. The conclusion that the performance of LCL type harmonic current suppressor is better obviously. The simulation contrastive verification was combined with simulation model. At last, the experimental platform based on DSP was set up. The experiment waveforms which were recorded and was analyzed by FFT, the result show the validity of the theoretical analysis and simulation performance above.
