Power distribution network clock synchronization correction method based on intrinsic electrical phase difference

The invention discloses a power distribution network clock synchronization correction method based on an intrinsic electrical phase difference. The method comprises the following steps: firstly, acquiring steady-state voltage and current at the head and tail ends of a distribution network, steady-state current positive-sequence components of distributed measuring points and positive-sequence waveimpedance and propagation constants of a line through a symmetrical component method; secondly, selecting step length, using head-end steady-state voltage and current phases as references, using head-end and tail-end positive-sequence electrical quantities for calculating non-synchronous phase differences of steady-state currents different in distance from the head end to acquire a mean value andsynchronizing the head end and the tail end of the distribution network; thirdly, calculating a steady-state voltage positive-sequence component of the distributed measuring point by utilizing the head/tail-end steady-state vo
