The invention relates to the technical field of power distribution and utilization and communication, in particular to a multi-source wide-area power distribution and utilization
terminal time correction method and device,
electronic equipment and a
chip. The time
correction method comprises the steps that a multi-source
fusion power distribution and utilization terminal obtains reference time
service time based on a preset reference time service source or based on multiple different time service sources, a time service deviation value between the reference time
service time and the time
service time of the to-be-corrected time service source is calculated, a time service time optimization parameter is determined according to the time service deviation value in combination with a
moving average filtering
algorithm improved based on Pearson's correlation, and the time service time optimization parameter is used for correcting the time service time of the to-be-corrected time service source. When time service time optimization parameters are determined, a
moving average filtering
algorithm which is improved based on Pearson's correlation is combined, and the correlation between data is considered, so that
noise can be effectively filtered,
time deviation can be smoothed, the accuracy of time service correction is improved, and the high-accuracy time service synchronization requirement of the power distribution and utilization terminal in a power
system is met.
