CEPELs Synchronous Phase Measurement Laboratory (LabPMU), in Cidade Universitria, Rio de Janeiro, RJ, is a laboratory infrastructure conceived to provide performance tests of PMUs and research on applications based on this technology. The wind turbine model generates a reference armature current that is compared with the actual armature current of the motor. This tickbox freezes the input allowing you to effectively take a snapshot of what is displayed on the oscilloscope at a given instant in time. A much larger inertia than traditional dc-ac converters is introduced. Without compromising optimal parallel execution, the simulators computational cores are shielded from real-time glitches, for jitter in the microsecond range. Another issue is the large minimum turn-on time of the used IGCT semiconductors, which permit the use of conventional modulation schemes. It is also worth noting that because bay-by-bay tests are performed, it is often not possible to evaluate the dynamic behavior of the other bays in the event of a real disturbance due to the lack of modeling of their components and interconnections.

This presentation shows a control-hardware-in-the-loop simulation to test the actual converter control platform in case of a grid fault. With the possibility of recording thousands of measurement points, RT-LAB provides users with a complete data history. In addition, the incidence or prevalence of an event cannot be determined from this reporting system alone due to under-reporting of events, inaccuracies in reports, lack of verification that the device caused the reported event, and lack of information about frequency of device use. Secondly, a real HIL lightweight IED controller based on an iec61850 library is developed. Real-time simulators are a useful tool for small academic laboratories to study on MMC. Part 2: Non-real-time or offline simulation methodologies using numerical solving techniques for network or component models have their limitations with respect to the necessity of high complexity. The obtained results demonstrate that the light-weight MGC approach and data modeling of various IEC 61850 predefined data object LNs are correct for the design of the power balance control/protection function against cyber attack. There are a variety of use cases that can introduce various abnormal scenarios that may be encountered in a real power system.
