A Study on the Introduction Effect of Superconducting Generators

초전도발전기의 도입효과에 관한 연구

The superconducting generator and motor have many advantages over the conventional machines. The better characteristics originates from the higher magnetic field density by way of superconducting field coil which conducts the operating current with very large density. The major merits of the superconducting machines can be explained as the smaller size and weight as well as the higher efficiency. The compactness would be very useful for the applications such as ship propulsion motors and the higher efficiency is expected to play a good role in saving the electricity generation cost for the generators used in power plants. In spite of these advantages the main reason for the lazy commercialization is known as the expensiveness of the superconductors and the cryogenic systems. In this paper focusing on the superconducting generator, we will consider and estimate the economic effectiveness when the machines permeate into the actual AC generator market in Korea gradually.
