基于复转矩系数法研究并网双馈风电场引发电力系统次同步振荡问题综述
摘要：风能作为一种可持续的清洁能源，近年来在我国得到迅猛的发展。双馈感应型风力发电机（doubly-fed induction generator，DFIG）具有灵活的控制特性，得到了广泛的应用，但由于其结构的特殊性，并网双馈风电场容易引发次同步振荡问题。该文首先介绍了并网双馈风电场引发电力系统次同步振荡（sub-synchronous oscillation，SSO）的机制。其次，对基于复转矩系数法的3类SSO问题的研究情况进行了系统性综述，并讨论了复转矩系数法的推广形式及其适用领域。最后，基于风力发电的前景和复转矩系数法的特性，对今后的研究方向进行了展望。
Abstract:The wind power is a kind of clean and sustainable energy which has been developed rapidly in China in recent years. Doubly-fed induction generator (DFIG) have been widely applied for wind power generations for its flexible controllability. However, due to the special structure of the DFIG, grid-connected DFIG wind farms may cause sub-synchronous oscillation(SSO) in power systems. This paper introduces the mechanism of SSO caused by grid-connected DFIG wind farms. Moreover, a systematic review of researches on the three types of SSOs based on the complex torque coefficient method is presented in the paper. In addition, the extension form and application area the complex torque coefficient method is explored. Furthermore, based on the development trend of wind power generations and the characteristics of the complex torque coefficient method, the research prospects are discussed.
