| 摘 要： | 大规模新能源接入电网增加了弱阻尼振荡模式被激发的风险。首先，考虑同步发电机和光伏的动态特性，建立了详细的小信号模型，分析了光伏对低频振荡模式的影响，提出了含光伏电站的电力系统低频振荡广域阻尼控制架构，实现光伏-同步机协调阻尼控制；然后，以特征值分析结果为依据，提出了广域阻尼控制参数的优化模型，并对控制参数进行优化整定；最后，在PSCAD/EMTDC平台中搭建了含光伏电站的四机两区域系统电磁暂态仿真模型，验证了所提广域阻尼控制方法的有效性。

| Abstract: | The grid integration of largescale new energy increases the risks of weakly damping oscillations. Considering the dynamics of synchronous generators and photovoltaic generations, this paper establishes a detailed small-signal model and analyzes the impact of photovoltaic generations on low-frequency oscillation modes. A wide-area damping control structure of low-frequency oscillations is proposed for power systems containing photovoltaic generations, so that photovoltaic generations and synchronous generators can dampen low-frequency oscillations. Based on the results of eigenvalue analysis, an optimization model of wide-area damping control parameters is proposed further Finally, the electromagnetic transient simulation model of four-generator and two-area system with photovoltaic station is built on the PSCAD/EMTDC platform. The time domain simulation results verify the effectiveness of this wide-area damping control method. |
