GE begins building world's largest WAMS in India

'Mega' grid-stabilization project fits nation's climate goals

GE Power's Grid Solutions arm announced yesterday the commissioning of the first leg of a "mega" grid-stabilization project that the firm believes will be the world's largest wide-area monitoring system (WAMS). The project is with Power Grid Corp of India Ltd (PGCIL) on the northern grid in India, and part of the Unified Real Time Dynamic State Measurement (URTDSM) initiative.

The initiative plans to monitor and control power supply across the entire nation, positively impacting the entire population, it added. The project was executed by GE T&D India Ltd, listed entity of GE Power's Grid Solutions business in India, GE said.

This first stage will let PGCIL monitor power flow across 110 substations and respond to fluctuations within a fraction of a second. This will be critical in addressing power supply and demand imbalances related to the integration of renewable energy with the grid.

When fully commissioned, the WAMS will be comprised of 1,184 phasor measurement units and 34 control centers across India and covering 350 substations. Part of GE Power's Digital Energy portfolio, the solution obtains input data 25 times/second from all the PMUs installed (as compared to conventional SCADA, sampling once in nearly 5 seconds), it added.

The system has real time views on geographic displays, analytical applications, and the capacity to store 500 TB (terabytes, or trillion bytes) of data. It will also fully secure the grid from any cybersecurity threat, incorporating the latest firewall policies, the firm said.

The development and testing of the new software and substation devices was undertaken by GE teams from India, the UK, and the US supported by PGCIL teams for a duration of two years.

"GE is responsible for about one-third of the world's electricity capacity," said GE Power's Grid Solution business CEO Reinaldo Garcia in prepared remarks. "In today's environment, this WAMS commissioning is considered a big leap forward – a remarkable, pioneering achievement which benefits the people in India."

"Our dedicated teams across the business are committed to successfully deliver on a project of this magnitude. Only GE can replicate this impressive solution for customers around the globe," he added.

"The digital transformation of the energy sector is one of the globe's greatest imperatives today," said GE Power Chief Digital Officer Steven Martin in prepared remarks. "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."

The Indian electricity network is the world's largest synchronized grid with a capacity of 363 GW, the firm said. India suffered the world's biggest power blackout in July of 2012, due to a grid failure which impacted over 620 million people across 22 states (nearly twice the population of the US, according to the US Census Bureau).

A committee of international experts formed by the Indian government to minimize the future possibility and impact of grid failure, recommended using a WAMS to measure the dynamic state of the grid and detect the onset of any unstable oscillation event, it added.
