    摘要： A method for controlling a pilot signal (Ps) to a WPPT with an adjustable coil ratio, wherein the primary side of the transformer is connected to a plurality of WTGs and a variable reactive compensation load, the method comprising the steps of receiving an actual primary-side voltage (V
    MV ), receiving an actual primary-side current (I
    QMV ), estimating a line drop voltage (D
    V ) on the basis of the compensation current (I
    QC ) and the actual primary-side current (I
    QMV ), forming a voltage error (Verr) as the sum of a rated voltage value (V
    R ) and the estimated line drop voltage (D
    V ) minus the actual primary-side voltage (V
    MV ), namely: V
    err = V
    R + D
    V V
    MV , and updating the pilot signal (Ps) in accordance with the voltage error (V
