基于直流电容电压动态的匹配控制是一种常见的构网型控制方式,其通过电容电压方程与转子运动方程间的等效关系构建基本控制逻辑。然而,由于直流电容上没有天然的物理阻尼,其运行时易因直流电压波动而耦合产生低频振荡问题。通过在直流电容上附加电阻虽然可以避免振荡,但也会带来较大的功率损耗。因此,从能量视角出发,揭示了直流电压波动产生低频振荡的能量本质。基于对暂态能量的分析,提出了一种改进的匹配控制方法,该方法增加了高通滤波反馈回路,以实现对暂态能量的快速耗散。最后,通过仿真验证了该方法的有效性,使匹配控制的低频振荡问题得到了缓解。
Matching control based on the dynamics of the DC-link capacitor voltage is a widely used grid-forming (GFM) control approach. Its basic control logic is established by leveraging the equivalence between the capacitor voltage equation and the rotor motion equation. However, because the DC-link capacitor inherently lacks physical damping, fluctuations in the DC voltage can easily couple into low-frequency oscillations during operation. Although adding a resistor across the capacitor can prevent such oscillations, it also introduces considerable power loss. From an energy-based perspective, this paper reveals the fundamental energy mechanism by which DC voltage fluctuations induce low-frequency oscillations. Based on an analysis of transient energy, an enhanced matching control method is proposed, which incorporates a high-pass filtered feedback loop to achieve rapid dissipation of transient energy. Finally, simulation results verify the effectiveness of the proposed method, demonstrating that it alleviates the low-frequency oscillation associated with matching control.
