Computer configurations

The current technology of Energy Management Systems computer configurations is reviewed in this paper. Computer system architectures have changed significantly over the years because of changing requirements from utilities and changes in the available hardware and software technology. The paper shows how configurations have evolved and in today's systems there is much commonality in approach. Finally, the current state of design suggests that new and more improved configurations will be achieved in the future that are greater in power but are more simplistic in design and more easily maintained.
