Solution
Our MMC hardware-in-the-loop solution
Our MMC solution includes a real-time simulator for the power grid network section. Connected to the real-time simulator, multiple I/O extension boxes specifically designed to interface with MMC controllers can be added depending on the number of cells required.
Our HIL MMC testing solution supports multiple functionalities
- Pole control and protection (PCP) functionality
- Valve base controller (VBC) functionality
- Communication Interface among controllers
- Coordination among controllers for different MMCs
- Evaluation of interactions between the MMC system and large-scale power systems.
