MiCOM Alstom P847 Phasor Measurement Unit
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.
Basic description:
Measures accurate, time-synchronised power system data
A key component of wide area monitoring, protection and control systems (WAMPACs)
Applications include: state estimation, situational awareness, stability monitoring, forensic analysis, network resynchronisation
Available in 3 CT/3 VT or 12 CT/3 VT configurations
Key customer benefits:
Real time monitoring and control of the power system
Available with ancillary protection, control and recording functions
Flexible communications
Graphical programmable scheme logic (PSL) eases protection scheme creation, and avoids the need for external logic controllers
Main characteristics:
Transmits IEEE C37.118-2005 synchrophasor data at up to 60 frames per second
Available with a full suite of back-up protection functions
IEC 61850 or DNP3 Ethernet station bus communication
Transmitted time-tagged signals are phase currents, voltages, their derivatives, frequency, rate of change of frequency plus binary signals
Overall differentiation factors:
Stand-alone PMU function in hardware familar, hardened and well-proven in the substation environment
Exceeds the requirements of IEEE C37.118 Level 1 with enhanced performance under off-nominal and dynamic system conditions
Real-time monitoring and control of the power system, especially when coupled with Alstom's e-terra and Psymetrix PhasorPoint solutions
Set and commissioned within the same MiCOM S1 Agile toolsuite as per MiCOM P40 protection relays
