Zynq-based NI Phasor Measurement Unit helps network grid operators juggle varying electric sources and loads

A phasor is a complex number that represents a sinusoidal wave’s amplitude, frequency, and phase. Electrical power-generation and –distribution companies use phasor measurements to help them gauge the health and efficiency of their systems as they enter the new world of many smaller renewable power generation plants (wind and solar) and new load challenges (conversion from incandescent lamps to compact fluorescents and LEDS and electric-car chargers, to name but two examples). National Instruments (NI) has just introduced a Phasor Measurement Unit (PMU) based on the company’s CompactRIO embedded-control and data-acquisition system. In turn, the NI CompactRIO is based on a Xilinx Zynq SoC.

The PMU is part of NI’s Grid Automation System, which is designed to be installed throughout a power grid. Readings from this distributed grid instrumentation then informs and guides control-room decisions. National Grid UK has already adopted NI’s Grid Automation System.
