| 摘 要： | 大规模风电场接入电网将削弱系统的惯性和阻尼特性，不利于电网安全运行。本文首先分析变速风电机组的传统功率控制，根据虚拟转动惯量与转速调节及电网频率变化的关系，提出适用于变速风电机组的虚拟惯性控制策略，解决高风电渗透率区域电网惯性不足的问题。其次，通过分析所提虚拟惯性控制对系统阻尼特性的影响，发现该控制方法对功率振荡具有抑制作用，实现了惯性控制与阻尼控制在有功环节上的有机结合。为进一步增强风电机组的阻尼能力，提出无功阻尼控制与虚拟惯性控制相结合的综合控制方案，从而完善风电场对系统的支持能力。最后，通过对含变速风电机组区域电网的仿真分析，验证在所提控制方案下风电机组不仅能够快速对电网提供频率支持，并且具备阻尼系统功率振荡的能力。

| Abstract: | The integration of large scale wind generation will seriously threaten the grid security for the lacking of effective inertia and damping. In this paper, based on the analysis of the traditional power control of variable speed wind turbines, the relationship between the virtual inertia, the rotor speed regulation and the network frequency variation is investigated firstly, and then the virtual inertia control strategy is proposed to support the inertia of the regional network with high wind penetration. Following that, the impact of the proposed virtual inertia control on system damping is discussed. An additional beneficial of the proposed control in terms of damping power system oscillations is observed, and thus the integrated control of virtual inertia with system damping on the active power loop is achieved. Furthermore, the reactive power damping control scheme is also devised to enhance the capability of the wind turbines to damp the power system oscillations corporately. Finally, a typical system with high capacity proportion of variable speed wind turbines is used to indicate the proposed control strategies. The simulation results show that with the proposed control scheme, the wind turbines not only have the fast respond to the network frequency, but also have the ability to damp the power system oscillations. |
