Alstom T&D India has secured a contract worth approximately INR38.2bn (€41m) from Power Grid Corporation of India Limited (PGCIL) for a critical energy management programme, ‘The Unified Real-Time Dynamic State’ project, in India.

The programme will enable nation-wide monitoring of power flows across the grid, responding to fluctuations within a fraction of a second. Real-time data ensures that PGCIL can intervene immediately to adjust and match electricity supply to demand.

As per the contract, Alstom T&D India will supply hardware and software solutions for the project.

The hardware solution includes supply of more than 1,300 MiCOM P847 phasor measurement units for collecting more than 18,000 real-time synchronised measurements from 351 substations in India.

The software solution includes installation of Alstom’s e-terraphasorpoint in 34 control centres at existing national, regional and state load dispatch sites. E-terraphasorpoint is a software solution that analyses weak spots in the system in real-time.

E-terraphasorpoint will detect evolving disturbances, tap into latent electricity capacity across electrical transmission corridors, and provide actionable information to system operators to take timely decisions to prevent events, such as blackouts.

"E-terraphasorpoint is a software solution that analyses weak spots in the system in real-time."

Alstom Grid Power Electronics and Automation senior vice-president Patrick Plas said this is a significant change in India’s energy management and the company is delighted to play its part in allowing a more intelligent grid.

"The timeliness and quality of the data will provide control room operators with the smartest tool yet to optimise the existing grid assets. This will ensure reliability, and ultimately provide the highest availability of electricity to India’s citizens. This is unmatched in the history of grid management," Plas said.

Alstom claims that its wide area monitoring system provides an unprecedented time-synchronised snapshot of conditions across India.

The monitoring system gives visibility on power system dynamics and wide-area stress indicators across the country’s vast circuit of up to 102,100km of electrical grid, which ranges from 132kV to 765kV AC with 172 substations.
