Recently, many utility companies have been adding synchrophasor measurement capability to their systems. Synchrophasors can provide operators with additional information about current system state, and can be used to improve the accuracy of state estimation. Currently, many transmission operators do not have the ability to process, store, and utilize the data from their own phasor measurement units (PMUs) locally; instead, they rely on larger data concentrators located elsewhere. We present a design for a phasor system, called the flexible integrated phasor system (FIPS), to provide a more flexible, lower cost alternative to provide independent system operators and transmission owners ready access to their phasor data. This provides a robust foundation for a variety of smart applications.
