The application discloses a fusion
processing system and method for multi-source heterogeneous data of a power
system under a 5
G network, relates to the technical field of fusion
processing of multi-source heterogeneous data of a power
system, and comprises the following steps: collecting adjacent node phase angles, active power,
voltage and
time deviation on a unified time axis to generate observation paired
phase angle difference and relative
time deviation estimation; obtaining an electrical expected
phase angle difference according to a small-angle
power flow approximation, and mapping the relative
time deviation to a 5
G network projection
phase angle according to a
power frequency; performing difference on the three and normalizing the difference according to a
noise equivalent standard deviation to obtain an inconsistency, complete paired network correction and generate a weight matrix; performing weighted
least squares under the participation of the weight to obtain a
state vector, and performing consistency review by residual error measurement to realize reliable fusion calculation under time
delay fluctuation conditions. The application can separate network errors, and improve fusion precision and robustness.
