IEC 61850-Based Centralized Busbar Differential Protection with Data Desynchronization Compensation

Demonstration of Adaptive Overcurrent Protection Using Iec 61850 Communications

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...

Iec 61850 Object Models of Multifunctional Distribution Protection Ieds

The paper analyzes the IEC 61850 object models of multifunctional distribution protection IEDs. The functional hierarchy, protection and non-protection functions are described. A single logical device and multiple logical device models are presented.

T Implementation Issues with IEC 61850 Based Substation Automation Systems

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...
