Fault currents of inverter-interfaced distributed generators (IIDGs) depend on inverter controllers. Thus, IIDGs fault are different than those synchronous-based DGs, both from the magnitude and waveshape perspectives. In event short-circuit faults, droop-based switch between a voltage source current source, which increases complexity non-linearity calculation (SCC). This paper proposes new SCC...

Fault current limiters are essential devices used to protect the power system and its equipment against high levels of fault current, which growing up due increase new sources. This paper proposes a novel design Hybrid Superconducting Current Limiter (Hybrid SFCL), is composed basically by thyristors in series with superconducting element. branch connected parallel an air-core reactor, improves...

Abstract: This paper describes analysis, modeling and simulation of electrical transient fault-current detection in power systems. The proposed modeling is based on simple numerical integration only, which is able to efficiently handle some sophisticated calculation. The proposed fault detector methods are sliding root mean square (SRMS) and PQR transformation technique. In this paper, an abnor...
