dc.description.abstractDue to the development of power electronics technology, the properties of various devices connected to existing power system has changed rapidly in recent years. In particular, PCS, which is the main attached equipment of ESS for seamless grid connection of renewable energy, operates power semiconductors (eg; IGBT, MOSFET) at high speed. The magnitude and frequency characteristics of the harmonics generated at this time are much more complex than the harmonics generated by the conventional passive load. Therefore, the existing protection relay system is affected by the characteristics of the new harmonics. In particular, the ground fault protection of the GVT based ungrounded system is more adversely affected. Therefore, in order to cope with such a problem, it is necessary to examine from the initial design of the system. This paper analyzes the effect of harmonics generated from PCS on ground fault detection of ungrounded system and analyzed it through computer simulation.
