An adaptive zero-sequence current protection scheme for distribution networks based on iterative fault current calculation of IIDGs

An adaptive zero-sequence current protection scheme for distribution networks based on iterative fault current calculation of IIDGs

Due to the inherent output fluctuations of inverter-interfaced distributed generators （IIDGs）， the fault characteristics of distribution networks have changed， posing challenges for relay protection setting. Taking a typical low-resistance grounding system with IIDG as an example， this paper first a...
