READ MOREAn electrical distribution system is a series of electrical circuits that delivers power in the proper proportion to homes, commercial businesses and industrial facilities. Regardless of the size and applications, the ultimate goal remains universal: the economic and safe delivery of adequate electric power to electrical equipment.
READ MOREFor this reason electrical power grids are most commonly represented in a single-line diagram format. This means each transmission or distribution power line appears as a single line on the page, rather than as three (or four) lines showing individual conductors in a three-phase AC circuit. Single-line diagrams work well to analyze the general
READ MORETime complexity function: O ( f ( N V, N E, N F, N N)) Step 1 of this algorithm takes the model of the electric power distribution system as its input, iterates through the list of power lines and cables and generates a graph represented as an adjacency list in a single pass. Its complexity is therefore O ( f ( N E)).
