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%
Performance Parameters
- Rotational Speed: 187,5 rpm
- Continuous Power Output: 700kW
- Continuous Torque: 36500 Nm
- Efficiency: 97,9 %
- Short-Term Power Output: 900 kW
- Short-Term Torque: 52500 Nm
