Power Grid's mega plan to monitor supply

The Phasor Measurement Units network will facilitate monitoring of grid events in real time

The Power Grid Corporation of India (PGCIL) is working on what would be the largest project for monitoring and controlling of electricity supply across the country.

Called ‘Unified Real Time Dynamic State Measurement (URTDSM)’, the central transmission utility would install ‘Phasor Measurement Units (PMUs)’ at all substations and generating stations. This would also form the backbone for efforts underway to integrate the large amount of renewable energy envisaged.

The plan is to install PMUs at close to 1,300 locations on the national grid in phase-I; 1,000 have been installed. In the second phase, another 500 PMUs would be installed along
