Designed to detect electrical network instabilities, such as over-voltages and transmission line overloads, the relay ensures fast remedial action in 170 ms, and also helps to mitigate frequency instability, when used in a smart grid environment with increasingly interconnected grids and electricity provided from multiple sources.
Hydro-Québec Technology executive vice president Élie Saheb said ”IREQ is pleased to collaborate with partners like Alstom Grid to develop technologies aimed at improving protection systems for the high-voltage transmission grid, thereby contributing to the quality of electricity service offered to Hydro-Québec’s customers.”
Alstom Grid Substation Automation Solutions vice president Hervé Amossé said, ”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.”
The two companies have also signed the Smart Grid Technology Innovation Partnership in 2012 with aim to jointly advance innovative technologies, such as wide area monitoring, protection and control systems (WAMPACS), which compare data from across a power grid to assess, monitor and assure its stability.
