PIECEWISE ANALYSIS OF LARGE-SCALE ELECTRICAL SYSTEMS BASED ON TWO-TERMINAL NETWORK PROPERTIES
We consider a modification of the effective method and algorithm for piecewise calculation of meshed electrical networks. The algorithm is based on use of active two-terminal network properties, overlap method (superposition), the compensation principle (replacement of electrical resistance branches with equivalent EMF source) and matrix transformations. One of the advantages of this approach is that the proposed algorithm allows to avoid constructing an intersections chain and challenges of merging solutions for complex systems when using a Mesh analysis and when the constructed subsystems do not have grounded nodes. By means of the corresponding matrix transformations the algorithm's incremental steps lead to the resulting formula, which is identical to the expression for the solution of equations of orthogonal chains. The algorithm is easy to implement for practical calculations on a computer.
