Variable-Speed Wind Turbines with Multi-Pole Synchronous Permanent Magnet Generators. Part I: Modelling in Dynamic Simulation Tools

Abstract: Variable-speed wind turbines are a promising concept for large offshore wind farms. The variable-speed concept can be realised with multi-pole synchronous generators (MPSG) excited by permanent magnets. The main advantages of this concept are that (i) the wind turbines are gearless and (ii) the electrical excitation system is replaced by permanent magnets. The electromagnetic construction of the permanent magnet generators (PMG) is, however, more complex than in conventional concept generators. The PMG are gri… Show more

“…At the same time, the grid-side converter controls the DC-link voltage and the reactive power flow to the offshore AC grid. In the traditional control strategy [10], the active power reference Pref is only provided by a maximum power point tracking (MPPT) approach and the wind turbine generator will not respond to grid frequency deviation. However, to implement frequency support, an ancillary frequency control loop [4], [6] is applied to wind turbines as illustrated in Fig.…”
