Structure optimization and preparation of power system grounding grid based on similarity data analysis algorithm

The grounding grid of power equipment is the most basic overvoltage protection device for system. Before design and construction grid, system generally uses a scaled-down model to verify characteristics grid. As types structures materials become more complex, there are one or similar items in simulation test that cannot be scaled down. This paper takes similarity new type material-flexible graphite composite material as an example. Firstly, complete theory deduced. Secondly, source distortion analyzed. Then, error different Finally, flexible taken example influence item simulation. research results this can provide reference tests, at same time, they applied tests other fields.
