    摘要:

    采用虚拟同步机(virtual synchronous generator, VSG)控制技术模拟同步发电机的外部特性，能够为电力系统提供一定的阻尼和惯性。然而，基于VSG控制技术的风力发电机（wind turbine generator，WTG）容易引起电力系统的低频振荡，为此，研究基于VSG控制的风电场并网系统的小信号稳定性。首先，建立单个和多个基于VSG控制的风力发电机、风电场并网系统的小信号模型；随后，通过求解状态矩阵得到系统的特征值，并分析系统的振荡模态；最后，根据特征值法进行虚拟惯量、虚拟阻尼以及线路连接电抗等参数变化对系统小信号稳定性的影响分析。

    Abstract:

    Using a virtual synchronous generator (VSG) control technique to simulate the external characteristics of the synchronous generator can provide certain damping and inertia for the power system. However, wind turbine generator (WTG) based on VSG control can easily cause low-frequency oscillation of the power system. In this paper, the small-signal stability of grid-connected wind farm systems based on VSG control is studied. Firstly, a single-small signal model is developed for both single and multiple VSG control-based wind turbine and grid-connected wind farm systems. Then, the system’s eigenvalues are obtained by solving the state matrix, and the system’s oscillation modes are analyzed. Finally, the effects of varying key parameters on the small-signal stability, such as virtual inertia, virtual damping, and line connection reactance, are analyzed using the eigenvalue method.
