6 FAQs about [Wind power low voltage generation voltage]

Why is low voltage ride through important in wind energy conversion system?

The high penetration of grid connected wind energy has emerged as a recent trend in many countries. On the other hand, the problem of power generation loss due to the grid fault also arisen. The recent technological advancement suggests the importance of low voltage ride through (LVRT) in wind energy conversion system (WECS).

Which LVRT methods are used in wind generators?

To deal with these issues simultaneously, this paper presents a comprehensive review of LVRT methods for the most common wind generators; squirrel cage induction generator (SCIG), doubly fed induction generators (DFIG), and permanent magnetic synchronous generator (PMSG).

Why does a wind generator draw more reactive power from the grid?

It draws more reactive power from the grid due to its self-excitation process during steady-state operation. The wind generator terminals are connected by low-cost Mechanically Switched Capacitors (MSCs) or shunt capacitor bank to provide unity power factor during voltage regulation.

What is low voltage ride through (LVRT)?

Low voltage ride through (LVRT) capability is an important requirement of grid codes. LVRT means that the wind turbine is still connected to the grid during grid voltage sags. This is essential for ensuring that no generated power by wind turbines is lost due to grid disturbances.

How to improve LVRT power of wind turbine?

For the pitch control method of LVRT improvement, the power of wind turbine can be lowered by adjusting the pitch angle of rotor blades. Nevertheless, because of the slow mechanical dynamics, this technique performs poorly 25.

Do wind turbine generators provide ancillary services?

With the increasing wind power penetration, the dynamic behavior of modern power systems changes. Wind turbine generators (WTGs) should provide the ancillary services to enhance the transient stability of the power system.
