Alstom Grid and Hydro-Quebec research institute IREQ have entered into a license deal to commercialise the MiCOM P848 loss of synchronism relay (RPS), hitting a key milestone in their Smart Grid Technology Innovation Partnership.

Specifically designed to detect electrical network instabilities including over-voltages and transmission line overloads, the technology ensures fast remedial action in 170ms, providing rapid protection.

The RPS will also help mitigate frequency instability in a smart grid environment with a large number of interconnected grids and electricity provided from various sources.

Hydro-Quebec executive vice-president – technology Elie Saheb said the new technology is expected to improve protection systems for the high-voltage transmission grid, contributing to the quality of electricity service offered to Hydro-Québec’s customers.

In 2012 Alstom Grid and IREQ signed a deal to jointly advance new technologies being commercialised with new solutions tested and validated at the research institute. In addition to the institute, the new solutions can also be applied to other systems.

"The partnership calls for researching various arenas including wide area monitoring, protection and control systems."

The partnership calls for researching various arenas including wide area monitoring, protection and control systems (WAMPACS), which compares data from across a power grid to assess, monitor and assure its stability.

Alstom Grid vice-president of substation automation solutions Herve Amosse said the company has developed the new product with Hydro-Québec that will improve grid transmission capacity and ensure a steady power supply to customers.

"Having previously collaborated on similar technologies, such as the P846 open line detector, Alstom and Hydro-Québec have built a core suite of products to protect power flow over long transmission corridors and to improve the security of Hydro-Québec TransÉnergie’s transmission grid," said Amosse.
