The Eastern Interconnect Phasor Project - Modernizing North America's Electric Grid

Abstract

The Eastern Interconnect Phasor Project (EIPP) seeks to implement on component of this new information landscape, namely information systems covering regional issues advanced through an effort involving a broad spectrum of stakeholders. Phasor measurement allows direct comparison and differentiation of the phase angles between corresponding phasor measurement units (PMU) from various locations across the power system. Operators receive the measurements time-tagged with accuracy in the order of microseconds. This high measurement accuracy is used to estimate, or in fact, calculate the power system state thereby improving the operational security of the power system
