Valiant introduces its VCL-PMU-30, Phasor Measurement Unit (PMU)

Valiant Communications introduces its VCL-PMU-30 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.

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”.

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-30-PMU is a Phasor Measurement Unit (PMU) 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.

VCL-30-PMUs includes an integrated GPS receiver (with the option of an external GPS receiver) to provide an accurate Stratum 1 quality time reference.

VCL-PMU-30 can be configured to provide accurate P and M class measurements using its internal GPS / GNSS Receiver, or it can be synchronized with an external IEEE-1588v2 PTP Grandmaster to acquire an accurate time reference. It can also synchronize with an external IRIG-B + 1PPS time input with better than 50ns. phase synchronized accuracy. Designed for use in the harsh substation environments, the VCL-PMU-30 is highly dependable and reliable, real-time power monitoring and measurement solution.

SCADA (Supervisory Control and Data Acquisition) systems, such as the RTUs are useful to provide steady state analysis in a power-grid. Phasor Measurement Units (PMUs), on the other hand, are the key elements of the Wide Area Measurement System (WAMS) for monitoring dynamic-state data and for providing transient analysis of a large and complex power grid in real-time.

VCL-30-PMUs communicate as per IEEE C37.118.1-2011, IEEE C37.118.2-2011 & C37.118.1a-2014 standards with Phasor Data Concentrators (PDCs) which are installed at the monitoring and control centres to provide a continuous real-time snap shot of the power grid, so that problem areas in the power grid can be isolated before any catastrophic grid failure and resulting power-blackout can occur.

VCL-PMU-30, Phasor Measurement Unit (PMU) accuracy is tested as per IEEE C37.118.1-2011, IEEE C37.118.2-2011 and C37.118.1a-2014 standards. The VCL-PMU-30 product is complied to meet and exceed all required regulatory compliances.
