摘　　要：结合金沙江电力外送 ,对分频交流输电方式进行了规划设计 ,并且与直流和交流输电方式进行了经济技术比较。结果表明 ,分频交流输电方式不但可以大幅度提高输送功率 ,而且在经济性上非常优越 ,是一种很有发展前景的输电方式。In view of power transmission from Jinshajiang to Central China a fractional frequency power transmission system is planned and designed. Digital simulation of fractional frequency transmission system is performed. The technical economical comparison through the above mentioned simulation of the proposed method with that of traditional ac and dc transmission system shows that using fractional frequency transmission system the transmitted power can be remarkably increased. This method is not only of economical superiority, but also feasible.
