Description : This paper presents a new algorithm for simulation of large scale nonlinear systems. The algorithm is a development and generalisation of Kron's ideas on tearing linear systems and it combines Newton-Raphson iterative process with diakoptical calculation of state increments in each iteration. The nonlinear network tearing algorithm has been implemented in 3L Parallel Fortran 77 and run on a 5 transputer system hosted in a Unix workstation. Computational results, obtained for a realistic nonlinear system, are provided and discussed. 1. INTRODUCTION Decomposition can provide a useful basis for the optimisation or control of many large scale systems. Physical structure of the problem often facilitates its partitioning into a number of smaller subproblems which can be solved individually, and the results recombined to achieve the solution of the overall problem. To take into account interactions between the subproblems, the overall solution proceeds as a sequence of subproblem solution...
