Abstract:
Smart grids use intelligent control technologies to generate power and improve energy efficiency. These systems use clever power converters, renewable energy, and efficient resources. Modern and basic multilevel inverters are used in high voltage power supply systems, however electronic power component failures greatly impact system reliability.
Measurement and determination of power component boundary conditions and operating regimes are crucial to smart grid definition and dimensioning. This research provides a novel power component defect detection method for a three-phase multilevel inverter, a smart grid component.
This approach detects single, double, and triple switch failures. The detecting technique analyzes stator current to distinguish between simple and multiple switching failures.
Multilevel converter models, created from basic components and using customizable subsystems to switch between converter topologies, are also discussed in the study. These models can also do harmonic analysis to check system accuracy and simulate operational scenarios to test control system functionality.
