摘　　要：全球能源互联网的提出,对微网并网技术的要求更加严格。本文通过分析微网并网前后的要求及其并网运行的特点,在深入研究电压源换流器(VSC)技术的基础上,提出开展将背靠背VSC技术用于微网并网的研究。研究表明,将背靠背模式的VSC装置用于微网并网开关,可以快速并网,冲击小,具有良好的隔离性,有功、无功独立灵活控制,稳定微网电压,增强微网运行的稳定性,提高电能质量。The proposal of global energy internet has stricter requirement to the microgrid interconnection technology. In this paper,the study on the application of back-to-back VSC technology to the microgrid interconnection is proposed through the analysis of before and after microgrid interconnection and its interconnection operation characteristics and also on the basis of deep study of voltage source converter（VSC）.It is shown by the study that the application of back-to-back VSC device to the microgrid interconnection switch achieves fast interconnection with less impact,has good isolation,independent and flexible active and reactive control,stabilizes microgrid voltage,increases stability of microgrid operation and improves power quality.
