- Abstract:
- In order to build 3D simulation model of transformer substation,the device should be indentified quickly.But the 3 D data of substation equipment was so large that it was difficult to identify quickly.This paper used dimension reduction to reduce the amount of data.It provided a method to identify equipment quickly using the dimension-reduced data.After analyzing the characteristic of the dimension-reduced data,a method using boundary curvature of dimension reduction point set was proposed.In the process,a rolling method based on principle of Alpha Shapes to extract the boundary points was proposed.The curvature of the boundary point was acquired by point-to-chord distance accumulation.Then equipment was idenfified by using boundary curvature.The simulation results showed that the method was concise and efficient.It could identify different equipment and reduce the amount of calculation greatly.
