Project Background
The main objective of this project is designing of a high power Modular Multi-level Converter (MMC) bridge working at medium frequency (0.2-1kHz) and verifying the design results using an appropriate MMC bridge model in PSCAD.
A 1000MVA, ±320kV, medium frequency MMC is studied and designed in this project. The MMC is intended to be used in high power DC-DC converters and DC hubs. These parameters analyzed include:
- Sub-module type (Half-bridge or Full-bridge);
- Number of Phases;
- IGBT switches;
- Processing resources;
- Modulation technique;
- Arm inductance and capacitance;
- Voltage balancing algorithms;
- Number of levels; and
- Operating frequency.
