The rapid pace of technological development shows no sign of slowing. Technological development has had and is still having a big impact on Substation Automation Systems. Nowadays, with the move towards electrical utility deregulation throughout the world, it is imperative to exploit the latest trends. Utilities and industry must be able to provide an even more efficient and cost-effective service. They must ultimately optimise their assets and stay ahead of the competition. This paper describes, by reflecting back on Substation Automation history, today´s developments and how users could utilise them in their Substation Automation Systems. In addition a summary of the gained benefits is given and some references are shown.
