The future of power systems: High-Speed Synchrophasor technology
A synchrophasor is a time-synchronized measurement of electrical quantities such as voltage or current in the electricity grid. It is measured by a device called a phasor measurement unit (PMU), which estimates the magnitude and phase angle of an electrical phasor quantity using a common time source for synchronization, usually provided by GPS or IEEE 1588 Precision Time Protocol. The resulting measurement is known as a synchrophasor, which is important because it allows synchronized real-time measurements of multiple remote points on the grid. PMUs are capable of capturing samples from a waveform in quick succession and reconstructing the phasor quantity, made up of an angle measurement and a magnitude measurement. Synchrophasors are used to monitor the state of the electrical system over many points and manage power quality.
A micro-PMU is a high-speed synchrophasor that continuously records and streams time-stamped power quality measurements. It is used to monitor the parameters like voltage phasor, current phasor, frequency and rate of change of frequency (ROCOF) in wide area measurement system (WAMS).
Micro-PMUs are used to monitor the parameters like voltage phasor, current phasor, frequency and rate of change of frequency (ROCOF) in wide area measurement system (WAMS). The microPMU acts like a power quality microscope, zeroing in on system health at different geographic points across the grid and taking perfectly synchronized snapshots of key data points like voltage, current and frequency. These insights are automatically combined to give you a real-time, eagle’s-eye view of your entire system with the sharpest clarity.
