What is a “Synchrophasor”?
A phasor is a complex numerical waveform representing a sinusoidal function whose amplitude, frequency and phase are time invariant (time-dependent system
function) and these phasor measurements, when accurately time stamped using GPS universal time, are called “Synchrophasors”.
VCL-PMU-30 is a modular Phasor Measurement Unit (PMU) that is designed to provide measured Synchrophasor values
in accordance with the IEEE C37.118.1-2011 and C37.118.1a-2014 synchrophasor standards. With ever increasing power demand, the power grid requires
efficient and reliable technologies to monitor voltage, frequency, phase angle and shifts in the power transmission network, in real-time, to detect
grid imbalances which can result in catastrophic grid failure and blackouts. The synchrophasor technology is used to monitor the power-grid in real time.
The VCL-PMU-30 which uses synchrophasor technology, which may be used to provide precise data, in real-time, for steady-state and dynamic-state
conditions for both M class and P class, at the desired frame rates. VCL-PMU-30 monitors voltage, frequency, phase angle and shifts in the power
transmission network in real time to detect grid imbalances, excessive loads zones and trouble spots which if undetected, can result in a grid failure
and power blackout.
