6 FAQs about [Analysis of generator operation at high wind temperature]
Why are high-speed generators affecting wind turbine design?
This is the main reason high-speed generators have continued to have such an impact on turbine design, especially for onshore applications. Wind turbine generator failures are one of the primary reasons for increased operations and maintenance (O&M) costs and generation asset downtime.
Are high-temperature superconductor wires a good choice for wind turbine generators?
Significant progress in high-temperature superconductor (HTS) wires enables MW-rated generator designs with lower volume and mass. There are many studies on superconducting high-power synchronous wind turbine generators.
How do wind resource and grid interactions affect a turbine generator?
For instance, the main bearing, gearbox, and generator (drivetrain) components are interdependent, functioning in unison for efficient energy production. Hence, wind resource and grid interactions affecting the drivetrain impact the performance and reliability of the turbine generator.
Are superconducting high-power synchronous wind turbine generators feasible?
There are many studies on superconducting high-power synchronous wind turbine generators. In , direct-driven wind turbine generators with HTS winding were studied in general, and their advantages were demonstrated in comparison with conventional generators. The feasibility of a 5 MW HTS wind turbine generator (WTG) was discussed in .
Can a 10 MW HTS generator operate under partial load?
The field winding can be wound into separate loops with separate cryostats, hence even if one of the field windings has a fault, the generator can continue to operate under partial load . Furthermore, the design only requires 2.4 km of HTS tape at an operating temperature of 65 K, which is a fraction of other 10 MW HTS generator designs [8-10].
How is the efficiency of a generator calculated?
The efficiency of the generator is calculated as ~ 96% in the transient state, only the eddy current in iron parts and the copper losses. The AC loss of superconducting tapes during the first transport current activation is not taken into account and examined in the situation where DC flows HTS racetrack coils.
