Experiment on Fractional Frequency Transmission System
IEEE Transactions on Power Systems, 2006The fractional frequency transmission system (FFTS) is a very promising long-distance transmission approach, which uses lower frequency (50/3 Hz) to reduce the electrical length of the ac power line, and thus, its transmission capacity can be increased several fold.

Feasibility study of fractional frequency transmission system
IEEE Transactions on Power Systems, 1996In their previous paper (1994), the authors proposed a new transmission system-the fractional frequency transmission system (FFTS) which uses lower frequency to reduce the reactances of AC transmission systems. This approach can multiply increase transmission capacity and remarkably improve operating performance.

Integrating Offshore Wind Power Via Fractional Frequency Transmission System
IEEE Transactions on Power Delivery, 2017A novel solution to integrating offshore wind power via the fractional frequency transmission system (FFTS) is introduced in this paper. The basic idea of FFTS is to improve the technical and economic performance of ac transmission systems by lowering the grid frequency.

Fractional frequency transmission system (FFTS), also known as low-frequency ac transmission system, is a promising solution to offshore wind power integration. The ac/ac converter is the most important equipment in FFTS. The modular multilevel matrix converter (M3C) is widely regarded as the next-generation ac/ac converter, but its complex control ...
