For Fault Isolation Units (FIUs), also known as Current Limiting Devices (CLDs), a system may be designed to address current and future technologies, wherein a device is installed between a power source and loads to limit the magnitude of fault currents that may occur within loads connected to power distribution networks; and
For Status Automatic Bus Transfers (SABTs), a system may be designed to address current and future technologies of SABTs, which is a solid-state three-phase, dual position, three-pole switch, consisting of six pairs of silicon-controlled rectifiers (SCRs) connected in an AC switch configuration.
Various events (disturbances) may be supported, either individually or simultaneously, or sequenced in time, including application/removal of three-phase faults, application/removal of phase-to-ground faults, application/removal of phase-phase-ground faults, and application/removal of phase-phase faults. In addition, other events may include branch addition/tripping, starting/stopping induction motors, shunt tripping/addition, and generator/SVC tripping. Moreover, impact loading, which involves changing a load based upon changing mechanical torque on an induction machine, and load shedding may be considered an event. During the impact loading, it may be possible to convert an induction motor into an induction generator.
According to the one embodiment, the understanding of stability trajectories may be automated, and their relevance to overall power system stability. For example, power system security may no longer be dependent upon the sole judgment of an individual user, but now may be automated.
