摘　　要：谐波治理是新能源场站运行中面临的重要问题。基于成熟的级联SVG拓扑,提出了基于级联SVG的新能源场站谐波抑制策略,根据不同的谐波治理需求,分别采用谐波电流治理、谐波电压治理和谐波电压电流综合治理3种谐波治理模式。最后以华东某新能源场站为实例,通过RTDS数字仿真实验验证了该策略可以有效地抑制各次谐波电压电流。Harmonic suppression is an important issue in the operation of new energy stations.Based on the mature cascade static var generator(SVG) topology,harmonic suppression strategies for new energy stations based on cascade SVG are proposed.According to different harmonic control requirements,three harmonic control modes are adopted:harmonic current control,harmonic voltage control and harmonic voltage-current integrated control.Then,taking a new energy station in East China as an example,the RTDS digital simulation experiments verify that the proposed strategies can effectively suppress various harmonic voltage and current.
