摘要/Abstract

摘要： 环境问题是一个全球性问题。解决环境问题的根本途径是大力发展清洁能源。构建全球能源互联网有利于平抑可再生能源波动，促进清洁能源发展。在高渗透率新能源的电网中还存在各种电力系统的稳定性问题。为解决这些稳定性问题，提出了同步电机对（motor-generatorpair，MGP）的设想和技术，并对其进行了理论和实验研究。先进行MGP的小干扰稳定性和暂态稳定性理论研究，发现MGP的阻尼二倍于单个同步机系统。再对MGP系统进行了实验研究，实验结果表明，MGP系统可以稳定运行。进一步实验结果还表明，MGP系统可以对电力电子逆变器产生的谐波起到滤除效果。最后总结MGP的技术优势和可能的应用场景。

Abstract: Environmental problem is a global problem. Developing clean energy and energy transformation is the best way to solve environmental problems. Building the global energy Internet is conducive in stabilizing renewable energy fluctuations and promoting clean energy development. However, there are still stability problems in high permeability power grid. Motor-Generator Pair (MGP) is proposed and its small signal stability and transient stability are analyzed to solve stability problems. Comparing with thermal power units, the stability of MGP is similar and frequency response characteristic is better. Experiment results also show the stable operation of MGP system. Accroding to results, MGP system can filter harmonics generated by power electronic inverter. Finally, advantages and possible application scenarios of MGP are summarized.

Key words: global energy internet, motor-generator pair, high penetration, power system stability, renewable energy
