Effective short circuit mitigation using interphase power controller technology: system planning and engineering considerations

High influx of generators interconnecting to the transmission network lead to increased short circuit levels which can exceed the fault duties of substation equipment. This paper illustrates effective short circuit mitigation options that were considered for addressing real life utility problems, by applying interphase power controller (IPCs). Upon a brief description of IPCs, a systematic procedure involved in the selection of IPC parameters, from a system planning viewpoint is provided. The specific advantages of the IPC technology associated with the design, engineering, and scheduling considerations are also addressed.
