基于虚拟同步发电机技术的变换器控制方法研究

摘要

The technology of Virtual Synchronous Generator ( VSG) has become a hotspot in the recent research due to its ability in endowing the power electronic converter with inertia of a VSG and improving the stability of the grid.This paper reviewed the principles of the VSG technology, introduced the schemes and control strategies for the present three typical types of VSG technology, compared their operation features, and finally summarized the VSG technology and looked into the future prospects of the VSG in development and application.%虚拟同步发电机技术，因其能够控制电力电子变换器具有同步发电机惯性以改善电网稳定性而成为近期的研究热点。阐述了虚拟同步发电机技术的原理，介绍了现有的三大类典型性的虚拟同步发电机技术方案及其控制策略，对比了各自的运行特点，最后对虚拟同步发电机技术进行了总结并对虚拟同步发电机技术今后的发展与应用进行了展望。
