There is now considerable pressure on electric utilities to operate their power systems in the most efficient manner possible and to provide increased quality of service to customers. This pressure, coupled with the decreasing availability of reserve margins, dictates that there is a requirement for comprehensive power system operation support through, among other things, the provision of quality information relating to the behaviour of the primary and secondary systems. This paper shows how the data available within modern substation control and management systems can be exploited in a cost-effective manner, through the implementation of advanced substation functions in an open systems environment. Certain functions which are presently carried out at the control centre could be distributed (or partially distributed) to the substation. These functions may provide utility staff with quality information, which can in turn be used to satisfy the objectives of increasing quality and security of supply, in addition to optimising the utility's information, maintenance and asset management functions
