Modularized Electrical Power Systems: The Three-Bus Architecture

The modularization of industrial plants concerns the decomposition of the system into multiple subsystems that are built in yards located in different areas of the world and then assembled on the construction site. This design philosophy allows for the reduction of construction costs and schedules. Unconventional plant solutions can make the most of this system concept in the electrical sector. In this article, an alternative architecture for electrical distribution is proposed. The suggested scheme allows the reduction in the number of items of equipment and the weight of the system, resulting in an optimal solution for a modularized system. The results are achieved by decreasing the required installed power and the weight of the copper used for the cables.
