The invention discloses a method for analyzing a power cable compensation scheme using reactors in parallel. The method comprises: forward-sequence parameters of a power cable are determined and a transmission matrix is determined on the basis of the parameters; equivalent forward-sequence parameters of the power cable which is connected to a power grid on two ends are determined, the transmission matrix is corrected according to a parallel compensation method of the power cable, and the correction methods for uniform compensation and concentrated compensation are different; then on the basis of the active power of transmission at the sending end or the receiving end of the power cable, the voltage and the current of one of the ends are determined through the dichotomy; and with the transmission matrix combined, the voltage and current distributions along the power cable are calculated, and the active power and the reactive power of the sending end and the receiving end are determined. Compared with the prior art, the method is widely applicable. As long as the forward-sequence parameters of the power cable are provided, the operation features of a corresponding compensation scheme can be output. The method provides the accurate distribution situations of the voltage and the current along the power cable, which facilitates further analysis of overvoltage and overcurrent possibilities.
