The present application relates to the technical field of electrical
system design, and particularly relates to a
spacecraft electrical
system interconnection component path planning optimization method and
system. The method comprises the following steps: obtaining
interconnection component data; constructing adjacency relationship according to the
interconnection component data to obtain component adjacency data; selecting a
beam splitting point according to the component adjacency data to obtain
beam splitting point data; estimating point port cost of the
beam splitting point data to obtain point port cost data; generating a control linkage graph according to the component adjacency data to obtain control linkage graph data; generating an interpretation field according to the control linkage graph data to obtain interpretation
field data; determining the splitting benefit of the point port cost data and the interpretation
field data to obtain splitting benefit data; and evaluating the hard constraint of the splitting benefit data to obtain beam splitting point feasibility
evaluation data. The present application realizes the constraint of the beam splitting point position and the control
semantics, effectively avoids the cross-stage control reversal and redundancy failure problems.
