This paper proposes a new backup protection scheme, named coordinated backup protection (CBP) scheme, for distribution networks containing distributed generation. The proposed protection scheme takes into account the issues faced by traditional backup protection, such as difficulty in setting parameters and complex cooperation, and considers the features of distribution networks, such as change...

This paper describes a new concept of automated fault analysis where fault transients and changes in power system equipment contacts are processed on-line. This allows faster confirmation of correct equipment operation and detection of unexpected equipment operations, as well as increased accuracy of fault location and analysis. The paper discusses two independent utility examples that illustra...

The reliability of smart substations has a great significance on the safety and stability of smart grid operation. Taking the protection system in smart substation as an example, this paper constructs comprehensive reliability models to evaluate the reliability of smart substations with different architectures. The paper first illustrates two important aspects which affect the reliability of th...

The authors propose a full three-dimensional (3D) calculation model based on a multipole technique able to predict the magnetic field pollution outside of indoor medium voltage/low voltage (MV/LV) transformer substations. The authors demonstrate that the proposed model may be advantageously used in all problems related to the characterization of the electromagnetic environment around a MV/LV tr...

Gas-insulated substations (GIS) have different specifications in proportion to air-insulated substations. Transformer failures related to lightning and switching are often reported in the gas insulated substation (GIS). This problem is the voltage magnifications due to reflections of switching and lightning surges at various junctions within the GIS. thereby overvoltages in GIS are more importa...

Substation optimization involves positioning a substation(s) at the most suitable point with minimum cost. In this study, multiple data were collected from Turkish Electric Distribution Incorporated Company (TEİAŞ) for substation in Eryaman region. The substations will be placed straight points. Using capacity of substations, power, voltage drops, and service interruptions calculated 10-year pl...

The creation of the data model and the configuration of the communication system represent essential tasks of engineering substation automation systems With SCL (Substation Configuration Description Language) the system standard IEC 61850 provides a standardized formal representation of the data model and communication configuration of substation automation systems. The substation model of SCL ...
