Small Low-Cost Hydroelectric Generator
Permanent Magnet Generator on the Power Grid

Requirement
  • Single quantity product (first design must fit – no chance for redesign)
  • The induced voltage at idle must match the mains voltage as closely as possible
  • High power factor and low current harmonics
  • No active control – the generator has to be designed for a wide power range
  • Permanent magnets must not demagnetize during short-circuiting
Solutions
  • Parametric models provide a cost-effective design even for single quantity products
  • Complex requirements can be considered and optimized
  • Mismatch between the simulation and measurement below 1%
