Abstract

Designers of modern power distribution systems are considering new zonal architectures that offer several ad vantages over traditional distribution architectures (e.g., a ring bus supplying radial feeders), including better recon figurability and greater survivability. Despite the potential advantages, there is some reluctance to implement these designs because of a lack of practical experience with them. This paper aims to give a better understanding of the performance of a zonal distribution system, and its response to fault conditions, by using detailed simulations of the power hardware and its control system. In this AC zonal system, we employ a wireless data communications scheme to interconnect a distributed array of fault detec tors and controllers. The utilization of wireless technology in AC zonal power systems aids in reducing cabling and weight of the system. The proposed system can be used in various applications where power continuity is a high priority, e.g in high-technology manufacturing plants or office buildings, but it is especially beneficial for use in isolated systems such as onboard ships or aircraft, where the initial construction costs and maintenance costs may be reduced. This work particularly studies how a wireless communication strategy affected the performance and responsiveness of an AC zonal power system. We used the Virtual Test Bed (VTB) as the environment for these studies.
