The down side of this automation was a multitude of proprietary systems from different manufacturers that made it challenging when there are requirements to extend existing substation automation system. Customers have had bad experiences that the cost to extend a legacy system is commonly much higher than a new system but unfortunately they have no upgrade path with a complete replacement of all IED's and software the only option. This is normally cost prohibitive as well as for most customers not possible simply due to the long shutdowns needed and as such they end up paying high prices to existing vendors to support old technology. The best option for utilities and industries would be to extend and upgrade their substation automation system while still maintaining their existing substation automation system devices. This upgrade should also future proof their substation by providing gateways to the new substation automation protocol, IEC 61850. This paper illustrates an example of a successful project implementation of one of the utility substation to rejuvenate their existing legacy system. It covers all areas of project life cycle such as requirement studies, design and the implementation.
