The company says the project for Power Grid Corporation of India Ltd (PGCIL) is the world’s largest Wide Area Monitoring System (WAMS) solution.
Sunil Wadhwa, Leader of GE Power’s Grid Solutions business in South Asia said, “The commissioning of the Wide Area Monitoring System technology of this scale and size is unparalleled in the history of power transmission in India. This will prove to be an important milestone in ensuring supply of uninterrupted, 24/7 high-quality power supply and integration of renewable energy with the country’s electrical grid.”
The project is part of the Unified Real Time Dynamic State Measurement (URTDSM) initiative that entails monitoring and controlling of the electricity supply across the country and has been executed by GE T&D India, part of GE Power’s Grid Solutions business in India.
The commissioned first stage will enable PGCIL to monitor power flow across 110 substations in the Northern Grid and respond to fluctuations within a fraction of a second. The northern grid covers nine control centers: Punjab, Haryana, Rajasthan, Delhi, Uttar Pradesh, Uttarakhand, Himachal Pradesh, Jammu & Kashmir and Chandigarh.
GE says “this 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 comprised of 1,184 Phasor Measurement Units (PMUs) and 34 control centers across India, 350 substations in the national grid.
GE said the solution obtains input data 25 times per second from all the PMUs installed, whereas conventional SCADA sampling occurs once in nearly five seconds.
It also offers real time views on geographic displays, analytical applications and the capacity to store 500 TB of data.
Moreover, it will also fully secure the grid from any cyber security threat, incorporating the latest firewall policies. 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.
Reinaldo Garcia, president of GE Power’s Grid Solution business said in today’s environment, “WAMS commissioning is considered a big leap forward – a remarkable, pioneering achievement which benefits the people in India”.
GE Power Chief Digital Officer Steven Martin added: “The digital transformation of the energy sector is one of the globe’s greatest imperatives today. It’s exciting to see PGCIL harnessing the benefits of real-time data monitoring, improved decision making, and stronger cyber protection in order to ensure a steady, resilient power supply.”
