Development of a quick-response superconducting generator model for electromagnetic transient analysis of power systems

In Japan, to realize low-carbon society, Advanced Low Carbon Technology Research and Development (ALCA) Project has been promoted to develop low-carbon technologies. The hydrogen cooled super-conducting generator (SCG) is one of them. SCGs have advantages such as low synchronous reactance and expansion of leading power factor operation, which expands the stability limit of power grid. Therefore, hydrogen cooled SCGs can be effective not only to low carbonization but also to stabilize high renewable energy (RE) penetration power grid. This study intend to model SCG with quick response excitation on electromagnetic transient (EMT) analysis software named eXpandable Transient Analysis Program (XTAP) and analyze grid stability, behavior of machines at power system fault situation, etc. accurately in order to reveal advantages of installing SCGs with quick response excitation.
