Description

The P847 Phasor Measurement Unit forms part of Alstom Grid’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 visualisation, 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 synchronised externally through a fibre-optic input (1PPS) and connected to an accurate IRIG-B source (the P594). The PMU function exceeds the requirements of IEEE C37.118 Level 1 with enhanced performance under off-nominal and dynamic system conditions due to an advanced frequency tracking algorithm.
