We developed an International Electrotechnical Commission (IEC) 61850-based centralized protection scheme to prevent single line-to-ground (SLG) faults in the feeders and busbars of ungrounded distribution systems. Each feeder intelligent electronic device (IED) measures its zero-sequence current and voltage signals and periodically transmits zero-sequence phasors to a central IED via a Generic Oriented Object Substation Event message. Using the zero-sequence phasors, the central IED detects SLG faults in feeders and busbars. To achieve centralized protection, angle differences between the zero-sequence currents and voltage phasors are exploited, and their calculation compensates for data desynchronization. The feeder IEDs were implemented using the MMS-EASE Lite library, while the transmitted zero-sequence phasors were calculated based on fault signals simulated by Power System Computer Aided Design / Electro-Magnetic Transient Design and Control (PSCAD/EMTDC). The central IED determined if the SLG fault was in a feeder or busbar by aggregating and analyzing the zero-sequence phasors received from the feeder IEDs. The results confirmed the validity and efficiency of our centralized protection scheme.


The advancement of communication technologies has facilitated the evolution of traditional electric power system into a vast entity called smart grid. Various domains such as substation automation, distributed energy resources, advanced metering infrastructures, energy storage systems and many more serve as parts and parcels of smart grid. Fundamentally, these domains communicate and exchange information within the domain as well as other domains to execute their intended functions. One example is the grid edge domain in smart grid, where devices at customer premise interact with utility grid as well as electricity market for applications such as demand response and energy trading. Generally, devices in grid edge domain exists independently to perform its specific functions. The information model and communication standards in these devices vary depending on the implementation by its manufacturers. This pose challenges for integration works which may require these devices to exchange information with each other. Therefore, this paper aims to design and proposeamultifunction virtual intelligent electronic device (IED) which capable of performing various applications at grid edge domain. The virtual IED utilizes standardized data model and semantics based on IEC 61850 standard. Information exchange based on IEC 61850 is then simulated between the virtual IED and a Client Simulator. The results indicate successful communication and information exchange based on IEC 61850 standard hence demonstrates the potential applications of the standard for grid edge domain.

In this study, we describe the development of a plug-in type of switchgear that can control bidirectional power flow. This switchgear system can connect distributed generations such as photovoltaic and wind turbine generation, and AC and DC loads. The proposed switchgear system consists of an inverter for connecting distributed generations and DC load, a static transfer switch (STS) that can control and interrupt the bidirectional power flow, and an intelligent electronic device (IED) that can control each facility using a communication system. Since the topology inside the switchgear is composed of DC bus, it can be operated as a plug-in type of system that can be used by simply connecting the converters of various distributed generations to the inverter in the developed switchgear system. In this study, we describe the overall structure of the proposed switchgear system and the operation of the components. In addition, prototypes of each facility are developed and the results of building a small testbed are presented. Finally, we verify the operation of the inverter by performing an experiment on the testbed and show that throughout a test sequence the proposed switchgear system works normally. The contributions of this study are the development of a plug-in type of switchgear for AC/DC and the actual test results presented through prototype development and testbed configuration.

Vietnam\'s electricity system has been increasingly invested in development, meeting the growth rate of energy consumption demand in all socio-economic aspects. In particular, the energization and commission of solar and wind power plants greatly affect the stability and safety of the Vietnam power system. To improve the system\'s stability when incidents occur, one of the current solutions is to coordinate relay calibration settings which have a rapid reaction time at all voltage levels. To meet the above requirements, an option is to use Intelligent Electronic Device (IED) with fast processing speed, reduced latency, and multiple functions with intelligent algorithms. In addition, the solution to coordinate the protection areas between IEDs is being concerned. This paper presents the coordination of Permissive Over-Reaching Transfer Trip (POTT) interlock function of SEL 311L relay for power transmission lines to reduce the fault clearing time compared to the traditional calculation method.

En este documento se analiza la implementación de la metodología del nuevo estándar IEC 61850 GOOSE (Generic Object Oriented Substation Event) de manera que se compara la misma contra la metodología convencional en pruebas fundamentales de relés de protección aplicado a subestaciones de alto voltaje. Adicionalmente tambien se analiza el desempeño de este nuevo estándar con el nuevo concepto de mensaje de comunicación a nivel de IED (Intelligen Electronic Device). Se obtiene un alto rendimiento en la red de datos gracias al medio de transmisión que es inmune a los problemas de interferencia electromagnética característicos en estos sitios, ademas de la flexibilidad en la reconfiguración de los parámetros de operación del sistema de protecciones
