LAWS OF ELECTRICAL GRID ANALYSIS
Journal Title: Електротехніка і Електромеханіка - Year 2014, Vol 0, Issue 1
Abstract
Calculations of electrical network currents can be performed with four law systems, namely, Kirchhoff laws, under current limitation via electrical parameters and constant or variable network topology; "alpha" and "beta" laws, under current limitation via network arms transmission capacity.
