Capacitor break-point partitioning of multi-machine systems for numerical integration by parallel processing

The ability to partition multimachine power system equations is very desirable because it enables the differential equations to be numerically integrated by many processors in parallel. This paper examines the reason for the present difficulty in achieving “partitioning”. The finding is that the “natural laws” are favorable to “partitioning” and the difficulty has arisen from the man-made assumption of neglecting the “electrostatic voltages” which accompany the magnetic induction process. By taking advantage of the capacitors which are present naturally in the power system, one can, in principle, use them as break-points for partitioning. The feasibility of the method is demonstrated in real-time simulations of a two-turbogenerator system by parallel processors
