Substation primary plant and instrument transformers generally remain in service for many years and are only renewed when physically or mechanically life-expired. However, substation protection and control systems, also known as secondary systems, are changed more frequently, especially electronic or computer based systems. One way to overcome the lifecycle-coordination problem is to develop a new architecture for substation secondary systems by deploying new technology such as standard interface modules, the bay process bus and IEC 61850 communication protocol. IEC 61850-9-2 'process bus' has proposed an Ethernet based communication network to replace traditional hardwiring and cabling, for communication of analogue and binary signals with Ethernet messages. The application of processbus in substations is able to reduce the life-time cost of the secondary systems and improve flexibility and functionality. Sufficient confidence must be demonstrated in the application of this new technology. This thesis describes the design and performance evaluation of a prototype protection scheme suitable for application on a corner of a mesh transmission substation of the type used in the UK on the transmission network.
