Abstract
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 firstly introduced the characteristics of FFTS. Then, two case studies of the feasibility of integrating hydro plant and wind farm via FFTS were carried out. Especially, the advantage of the fractional frequency wind generation and transmission system was discussed. The results show that the proposed FFTS based approach is effective with high potential for practical implementation.
