摘要
首先建立独立/并网模式下逆变器滤波高频模型,得出输出电压与并网电流的谐波计算公式。依据公式进一步分析滤波电感电容等参数与谐波抑制的关系,给出设计原则。通过设计实例,详细阐明设计原则及步骤,在综合考虑独立/并网模式下电压及电流谐波标准及控制稳定性等要求下,绘出设计曲线,得到性能成本最优设计参数。最后通过10kW逆变实验,验证了此设计方案的有效性。
A filtering high frequency model was first established in stand-alone and grid mode, which the formulas of voltage and current harmonic components were given, and the relationships between filter inductance and capacitance parameters and harmonic suppression were also analyzed. Based on the design example, design principles and procedures were expatiated in detail. Considering voltage and current harmonic requirements and control stability in stand-alone / grid mode, an appropriate LCL filter of the lower total inductance was designed. Finally, effectiveness of the optimized scheme was validated by the experiments in the lOkW inverter.
