Unbalanced distribution system short circuit analysis — an Object-Oriented Approach

A new object-oriented design (OOD) for unbalanced distribution system is proposed and employed for developing short circuit analysis software. The difficulty associated with the procedure-oriented implementation of short circuit analysis program is overcome with a new object-oriented implementation. The purpose of using object-oriented methodology (OOM) for unbalanced distribution system is to achieve a flexible software model for the complex nature of the system involving three phase, two-phase and single-phase components. Considerable reduction in the programming complexity can be obtained by the proposed method. The method was successfully tested on benchmark systems like IEEE 13-bus and IEEE 34-bus systems.
