An analysis of open-phase fault in power generation station

This paper attempts to investigate and analyze the electrical characteristics present on the power grid when an open-phase event occurs at an off-site transformer. In order to conduct such task, this paper uses transformer, load, and connection data obtained from a real power plant to simulate several different power system configurations and analyzes various model responses in EMTP-RV software. Several testing scenarios that encompass a variety of loading conditions that can be encountered at the power plant are also defined. At the end, open phase simulation for these scenarios is carried out and all results are presented and discussed in detail.
