Abstract: The invention relates to a power system real time nodal data three-dimensional visualization method which is based on the fast spatial interpolation, and belongs to the power system three-dimensionalvisualization techniology field. The method comprises the following steps that: the scale of rectangular grids is determined and drawn; the nodal data in a power network are collected; the parametersof the spatial interpolation algorithm are set; the calculation is carried out through the fast spatial interpolation algorithm; for each grid point (xi, yj), the interpolation result (vi, j) is calculated, the power network wiring diagram is taken as the background, and the two-dimensional scalar field visualization technology is used to express grid data (xi, yj, vi, j), so as to obtain the visual graphic of the real time nodal data, which is used to carry out the real time safety economy monitoring to the power network; while ensuring the rapidity, the invention remarkably improves the visual effect and the practicability of the three-dimensional visual graphic through introducing a dummy average point and modifying the weight coefficient.
