基于混合功率同步的构网型逆变器对称电网故障下暂态稳定性增强控制

The current limiter can effectively limit the overcurrent for grid forming (GFM) inverter, but it also makes the inverter easier to lose the stable equilibrium point (SEP) during grid fault. The untimely fault clearing, inaccurate fault depth detection and grid impedance measurement result may lead to overoptimistic deceleration effect evaluation and transient instability problem. In this article,...
