A Hybrid Framework for Adaptive Protection of Microgrids Based on IEC 61850
Microgrids can operate both in grid-connected and islanded modes. It is essential to protect microgrids against all types of faults in both of the operation modes. Conventional overcurrent protection schemes are not adequate for microgrids due to bidirectional flow of fault current and limited flow of fault current through semiconductor devices. In addition, the setting values of all the concer...
متن کاملCommunication Modeling for Wide-Area Relay Protection Based on IEC 61850
Wide-area communication system is supporting platform for wide-area relay protection (WARP) exchanging information, which includes not only visible physical communication equipment and links, but also communication protocols and other upper communication services. WARP communication has become an important issue in WARP practical applications, but it has not been described in IEC 61850 standard...
متن کاملIEC 61850 – What It Can and Cannot Offer to Traditional Protection Schemes
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...
متن کاملDemonstration 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...
متن کاملIec 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.
