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.

The Stability

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.

Protection equipment in intelligent substation includes Merging Unit, protection equipment and Intelligent Terminal. At present, the status of the intelligent electronic device in intelligent substation protection system is still lack of effective monitoring means. According to the characteristics that substation area protection can obtain current information of all circuits in substation through GOOSE network, a protection system conditioning monitoring relay named PSCMR is designed in this paper. Based on the principle of current differential, PSCMR can accurately identify the abnormal condition or malfunction of Merging Unit or Electronic Current Transformer and realize condition monitoring of intelligent electronic device in protection system.
