Fractional frequency transmission system (FFTS) is a promising integration method for long-distance offshore wind farms. This paper investigates the lifetime of the power electronics converters of the wind turbines under the reduced grid frequency. The mechanism of the influence of fractional frequency transmission technology on the service life of semiconductor devices in power converter is revealed. A new assessment standard for the deployment of fractional frequency transmission systems is provided. 1
