What it represents
A permanent-magnet synchronous generator provides an AC source using a permanent magnetic excitation system. Any converter between this source and the AC network must be shown separately.
How to read it
- Distinguish machine output from the downstream converter's controlled network output.
- The preview is an original explanation of this function. Match the actual drawing convention to its legend and the selected equipment documentation.
Information to show or reference
- State machine rating
- Identify winding terminals
- Reference converter interface
A distinction that matters
Permanent-magnet excitation does not mean direct grid connection is appropriate for every machine.
