As the latest standard that is quickly gaining popularity in power substation automation, IEC 61850 offers self-descriptive object data models, standardized configurability with Substation Configuration Language (SCL), the promise of interoperations among intelligent electronic devices (IEDs) from different manufacturers, and lower integration installation costs. The IEC 61850 standard initiall...

The recent international standard IEC 61850 proposes a unified solution of the communication aspect of substation automation. However, the standard itself is not easily understood by users other than domain experts. We present our understanding of the IEC 61850 standard as well as the design and implementation of our simulation tool in this report. Also, we give suggestions on the implementatio...

The introduction of the standard IEC 61850 for communication in power systems enables to build enhanced Substation Automation (SA) systems and to distribute requested functionalities in an optimal and standardized way. This brings new challenges and opportunities related to interoperability between compliant IEDs and tools as well as for testing and maintenance processes. The complete sequence ...

International Electro-technical Commission (IEC) has developed a new global standard, IEC 61850 for communication systems in power substations. This standard provides interoperability among the all communication devices within the substation. This paper presents basic features of communication systems proposed by IEC 61850, such as functional hierarchy, OSI-7 layer based communication, and proc...

The modern and high-speed Peer-to-Peer IEC 61850 has opened the chance for planning and developing the sampled values that are supported information exchange among IEDs. Over the method bus network, it’s important to comprehend the transmission responsibility and real-time performance of SVs and GOOSE messages for all-digital IEC 61850 station automation systems (SASs) protection applications t...

Today's power plants are highly automated. All subsystems of large thermal power plants can be controlled from a central control room. One subsystems area is the electrical auxiliaries for the unit transformer, the grid connection, excitation, synchronization, generator/unit protection, auxiliary transformers, HV-, MV-and LV-switchgear. In the past, these electrical devices were all hardwired t...

In this paper, it is argued that some low-level aspects of the usual IEC 61850 mapping to Ethernet are not well suited to microgrids due to their dynamic nature and geographical distribution as compared to substations. It is proposed that the integration of IEEE time-sensitive networking (TSN) concepts (which are currently implemented as audio video bridging (AVB) technologies) within an IEC 61...

The growth of a country is scaled by the amount of energy it consumes. In the developing India, with the rise of population, increasing number of cities and demanding villages, caused to set up transmission lines with higher capacity. Inter-ties were connected through the transmission lines to lighten every city and village, thus making the whole system complex. This complex system required a r...

With the proliferation of smart grids and the construction of various electric IT systems and networks, a next-generation substation automation system (SAS) based on IEC 61850 has been agreed upon as a core element of smart grids. However, research on security vulnerability analysis and quantification for automated substations is still in the preliminary phase. In particular, it is not suitable...

This paper contains a description of an adaptive protection scheme that has been implemented and demonstrated in a hardware in the loop simulation environment using commercially available protection hardware and IEC 61850 communications. The implementation is based on an actual 11kV system which includes distributed generation and network automation. IEC 61850 communications offers several bene...
