GEPower, arm of US-based General Electric announced it has commissioned the 1st phase of the world’s largest Wide Area Monitoring System (WAMS) for Power Grid Corporation of India Ltd (PGCIL) for the Northern Grid in India.The project is part of the around $52.2 million contract awarded to GE T&D in January 2014 to install WAMS across all five regional grids of north, south, east, west and northeast India.The company has commissioned 1st phase of the project.The contract was awarded in the backdrop of the world’s biggest power blackout faced by India in July 2012 due to a grid failure which impacted more than 620 million people across 22 states.The project will enable PGCIL to monitor power flow across 110 substations in the Northern Grid (NR) and respond to fluctuations within a fraction of a second, which will be critical in addressing power demand-supply imbalances and ensuring grid stability benefitting from the integration of renewable energy with the grid. When fully commissioned, this new WAMS solution will be the world’s largest comprising 1,184 Phasor Measurement Units (PMUs) and 34 control centers across India, 350 substations in the national grid.The development and testing of the new software and substation devices was undertaken by GE teams from India, the UK and USA supported by PGCIL teams for a duration of two years.
“This will prove to be an important milestone in ensuring supply of uninterrupted, 24X7 high-quality power supply and integration of renewable energy with the country’s electrical grid,”said Sunil Wadhwa, Managing Director, GE T&D India Limited and Leader of GE Power’s Grid Solution business in South Asia.Part of GE Power’s Digital Energy portfolio, this solution obtains input data 25 times per second from all the PMUs installed, with real time views on geographic displays, analytical applications and the capacity to store 500 TB of data.
