The standard IEC 61850 contributes the manufacturers and the end users. But it also makes many obstacles to the modification of the conventional substation. This paper presents a scheme which modifies an in-service conventional substation gradually to a modern substation which conforms to IEC 61850 standards. The procedure of the modification is divided into three stages. During the first stage, all...
IEC 61850 supports the use of functional designs for specifying substation automation systems. However, specifying such systems is not standardized within IEC 61850. This means that utilities are somehow left in the dark regarding the use of the engineering process defined in IEC 61850–6 and therefore often revert to using traditional and proprietary ways to specify their requirements. To overcome...
Currently, there are many challenges in the development of numerical, multifunctional Intelligent Electronic Devices (IEDs) paraphrased as relays in this paper. These are to continuously improve the design quality, to reduce the development period for shorter time to market, and to optimise the development cost and the product cost. One effective solution for these challenges is to develop automated...
This paper provides an overview of recent developments in high availability networks and new redundancy protocols designed to guarantee seamless failover and proper functioning of the most critical substation automation applications such as tripping via GOOSE (Generic Object Oriented Substation Event) messages and IEC 61850 Process Bus based on switched Ethernet. The authors describe most common redundancy...
