Abstract

The basic idea of the fractional frequency transmission system (FFTS) is to use lower frequency, e.g. 50/3 Hz, to reduce the electrical length of the AC transmission line, thus to increase its transmission capacity. FFTS is particularly suitable for transmitting electricity produced by the renewable energy, such as hydro power and wind power, because the rotation speeds of their generators are very low. The paper first introduces the characteristics of integrating large wind farm via FFTS. Then, a case study for feasibility of integrating wind farm via FFTS is carried out in considerable details. The results show that the proposed FFTS-based approach for wind power integration is effective with high potential for practical implementation.
