Distribution systems load flow based on loop-impedance equations and simulation visualization

Abstract:

A novel method of the load flow and simulation information visualization is proposed for simulating quickly and vividly the operation status of distribution systems. Combining the orthogonal list save distribution system topology and incidence matrix reflect current flow, an impedance matrix generation algorithm was designed to automatically calculate every matrix elements; a parallel Gussian elimination algorithm based on right-looking LU factorization was put forward, in order to accelerate the loop-impedance matrix equations solving by GPU; GIS and virtual reality technologies were used to visualize the result of load flow. Simulation examples show this method hasn’t special requirement for the node numbering scheme and is suitable for load flow of the radial and the meshed distribution networks for its rapid computation, high precision and visual intuitionistic display about simulation result.
