【摘要】：随着风力发电等新能源并网容量的增加,大功率电力电子技术的广泛采用,以多源多变换复杂交直流系统为组成架构的新能源电力系统逐渐形成,由此引发的次同步振荡新问题不断凸显,次同步振荡的概念和内涵不断延伸,它们的起因、表现形式、影响程度、监测和抑制方法等诸多错综复杂的问题再一次引起世界范围的广泛重视。本文首先总结新能源电力系统次同步振荡的基本问题与发展态势,并剖析我国次同步振荡问题的特点与表现,最后提出当前次同步振荡研究中的新问题,以及在抑制技术等方面面临的挑战与应对措施,以期推动我国次同步振荡问题的研究。
[Abstract]:With the increase of grid capacity of new energy, such as wind power generation, and the wide adoption of high-power electronic technology, the new energy power system composed of multi-source and multi-conversion complex AC / DC system is gradually formed. The new problems caused by the sub-synchronous oscillation continue to highlight, the concept and connotation of the sub-synchronous oscillation continue to extend, their causes, forms of expression, degree of influence, Many complicated problems, such as monitoring and suppression methods, have once again attracted worldwide attention. In this paper, the basic problems and development trend of sub-synchronous oscillation in new energy power system are summarized, and the characteristics and performance of sub-synchronous oscillation in China are analyzed. Finally, a new problem in the research of sub-synchronous oscillation is put forward. In order to promote the research of subsynchronous oscillation in China, the challenges and countermeasures in restraining technology are also discussed.
