Technical FAQs 4

What is the topology of direct-drive wind power generation systems?

The topology of the direct-drive wind power generation systems connected to the weak power grid is illustrated in Fig. 1, including the wind turbine, Permanent Magnet Synchronous Generator (PMSG), machine-side converter (MSC), DC capacitor, grid-side converter (GSC), filter inductors, and the AC power grid.

What is a new direct-drive generator for wind turbines?

aring new direct-drive generator for wind turbines has been proposed in . The fundamental idea of the machine - the NewGen (see Fig. 4-2-7) is to reduce the stiffness demand by removing the load path fro sta or by putting the bearing

What is the structure of a direct drive wind generator?

ical structures of direct-drive wind generators 3.1.1. Conventional StructureTraditionally the rotor of generator is connected to a shaft mounted on bearings that enable the rotation in the stator as shown in Fig. 23 The structure of Fig. 24(a) is widely used on the wi d turbine market by Enercon GmbH, whose world market share was abo

How does a weak grid affect direct-drive wind power generation?

The interaction between the direct-drive wind power generation system and the weak grid involves multiple time scales with overlapping interactions. The main reason for instability is that the introduction of loops 2 and 3 by the weak grid reduces the bandwidth of the current loop, causing frequency band overlap.
