PHASOR MEASUREMENT UNIT (PMU) PRO

A Wide Area Monitoring Revolution

A Phasor Measurement Unit (PMU) is a critical component of the Wide Area Monitoring System (WAMS) platform. These systems are designed to deliver real-time monitoring of nationwide transmission grids, offering insights to predict and prevent power failures while analysing those that have occurred.

The PMU PRO sets a new standard with its exceptional performance and cost-effectiveness, making it a transformative solution, particularly for Distribution System Operators (DSOs).

It seamlessly integrates with third-party Phasor Data Concentrators, a key element of WAMS, ensuring adaptability and versatility.

IEEE C37.118.2
- Synchrophasor data frames transmit a time stamped set of measurements that include phasor estimates, frequency deviation from the nominal power line frequency or actual frequency, and the rate of change of frequency. In addition, the data frame can be expanded to contain analog data (total active, reactive and apparent power, and power factor) and digital input status information.
  Phasor components can include three voltage and three current phasors, positive sequence voltage and current phasors, negative sequence voltage and current phasors, or all of them in one frame.
  Complex phasor values can be sent in a rectangular coordinates format (real and imaginary) or in polar coordinates (magnitude and angle). Phasor and frequency data can be represented in 32-bit IEEE floating-point format or as 16-bit scaled integer numbers. When using the integer format, the data conversion factors are provided in IEEE C37.118.2 configuration frames.
- Client-server UDP and TCP data transmission; spontaneous UDP data transmission over IP protocol
- Optional IEEE C37.118.2 frame extensions with analog data (total active, reactive and apparent power and power factor) and digital status data (up to 32 inputs)
- The PMU PRO supports CFG-1, CFG-2 and CFG-3 configuration frames.
  In spontaneous UDP data transmission mode, CFG-2 or CFG-3 configuration frames can be sent spontaneously without an explicit user command. When enabled, a configuration frame is sent periodically every 30 seconds.
