Doubly-fed induction generator wind turbines (DFIG-WTs) have been widely adopted by the current wind power generation systems (WPGSs) due to their cost-effective provision of a high efficiency energy conversion via variable speed operation. Most of the installed DFIG-WTs utilise vector control (VC) for the power control of DFIG. To cope with the increasing demand of integrating the large capacity of wind power into the current power grid, grid operators require that the WPGSs should ride through grid faults and support grid stability. However, VCs are not capable of providing satisfied fault ride-through capability as they are mainly derived based on the steady-state operation of the DFIG. On the other hand, the time-varying nonlinearities and disturbances existing in the DFIG-WTs are needed to be tackled so as to improve the energy conversion efficiency. This proposal will investigate an advanced nonlinear adaptive control algorithm for the DFIG-WT to improve the energy conversion efficiency, the fault-ride through capability and the support of grid stability. The proposed controller will adaptively compensate unknown and time-varying disturbances such as intermittent wind power inputs, the nonlinear dynamics of the DFIG-WT and the power grid. Without relying on an accurate system model, the developed controller will have a relative simpler control algorithm compared to other advanced control methods and can be implemented based on the current hardware used by the vector control method. Due to the wide usage of the DFIG-WTs in the current WPGSs and in the fast growing offshore wind farms, designing a novel controller and upgrading the current used VCs will have great practical importances and help the integration of large capacity of wind power into power grid.

双馈感应发电机风力涡轮机（DFIG-WT）由于其通过变速运行经济有效地提供高效能量转换而被当前风力发电系统（WPGS）广泛采用。大多数已安装的 DFIG-WT 采用矢量控制 (VC) 来进行 DFIG 的功率控制。为了应对大容量风电并入电网的日益增长的需求，电网运营商要求WPGS能够克服电网故障并支持电网稳定。然而，VC 无法提供令人满意的故障穿越能力，因为它们主要基于 DFIG 的稳态运行而得出。另一方面，需要解决DFIG-WT中存在的时变非线性和扰动，以提高能量转换效率。该提案将研究一种先进的 DFIG-WT 非线性自适应控制算法，以提高能量转换效率、故障穿越能力和对电网稳定性的支持。所提出的控制器将自适应地补偿未知的时变扰动，例如间歇性风电输入、DFIG-WT 和电网的非线性动态。所开发的控制器不依赖于精确的系统模型，与其他先进控制方法相比，具有相对简单的控制算法，并且可以基于矢量控制方法当前使用的硬件来实现。由于DFIG-WT在当前WPGS和快速发展的海上风电场中的广泛使用，设计一种新型控制器并对当前使用的VC进行升级将具有重大的实际意义，有助于大容量风电并入电网。
