[0017] The technical solution of the present invention will be described in further detail below in conjunction with the accompanying drawings.
[0018] The present invention proposes a cross-section alignment method based on real-time data quantitative delay estimation and prediction correction based on dual time scales. This method can quantitatively estimate the data sent by different RTUs and other scheduling centers according to the real-time sequence with GPS synchronous time scale collected by the PMU. EMS transmits the delay of data, and corrects the error caused by the delay through prediction, so that the transmission data from various sources can be integrated into a section that is closer to the current actual operating conditions, and the mismatch of data in the entire network is greatly reduced. The steps are as follows ( figure 1 Be the principle flowchart of the inventive method):
[0019] (1) Perform dual-time-scale sampling on the real-time data sent by the ...
