The P847 Phasor Measurement Unit forms part of GE’s system monitoring and control. The devices is used to measure power system data in real time and report to the PDC (Phasor Data Concentrator) for visualization, data storage and most importantly for running a variety of ‘on line’ and ‘off line’ applications in systems analysis and control. The ultimate goal is to run the system economically and preserve system stability following major disturbances.
The P847 is GPS synchronized externally through a fiber-optic input (1PPS) and connected to an accurate IRIG-B source (the P594). The PMU function is designed to support IEEE C37.118 – 2011 (2014 amendment) with enhanced performance under off-nominal and dynamic system conditions due to an advanced frequency tracking algorithm.
