FAQS about Power generation of Longyuan wind turbine

Does China Longyuan have a wind power plant?

China Longyuan had a full-scale construction and operation and maintenance platform for intertidal and offshore wind power, with the annual construction capacity of 350 MW, which is a key step in the large-scale development of offshore wind power.

Who is Longyuan Power?

A subsidiary of China Energy, Longyuan Power Group Company Limited (Longyuan Power) was founded in 1993. It is the largest wind operator in the world and the first specialised firm that produces wind power in China.

Where is China Longyuan building a wind farm?

At present, China Longyuan is building the offshore wind farm in Nanri Island, Fujian Province, which is the largest single offshore project in China, with a capacity of 400 MW.

How has Longyuan Power developed new energy?

Function of double-fed wind turbine generator

Doubly fed electrical generators are similar to , but have additional features which allow them to run at speeds slightly above or below their natural synchronous speed. This is useful for large , because wind speed can change suddenly. When a gust of wind hits a wind turbine, the blades try to speed up, but a is locke. Doubly-fed Induction Generators in industry are used to generate electrical power in large wind turbines. [pdf]

FAQS about Function of double-fed wind turbine generator

What is a doubly fed generator for wind turbine?

Doubly fed generator for wind turbine. Doubly fed electrical generators are similar to AC electrical generators, but have additional features which allow them to run at speeds slightly above or below their natural synchronous speed. This is useful for large variable speed wind turbines, because wind speed can change suddenly.

How does a double fed wind turbine work?

The stator of the doubly-fed wind turbine is directly connected to the grid and can only output power. In contrast, the rotor is connected to the grid through an AC/DC/AC power converter, with power flow determined by the generator's operating mode.

Why do wind turbines use a doubly-fed induction generator?

This allows the power factor of the system to be controlled e.g. in order to maintain the power factor at unity. While using a Doubly-fed Induction Generator in variable-speed wind turbines allows electrical power generation at lower wind speeds than with fixed-speed wind turbines using an asynchronous generator.

What is doubly fed induction generator?

The doubly fed induction generator (DFIG) is a portion of wound rotor and an adjustable speed IG widely used in wind power industry. DFIG provides high energy yields, reduction of mechanical loads, simpler pitch control, less fluctuations in output power, an extensive controllability of both active and reactive powers .

What is a double-fed induction generator?

Paul Breeze, in Wind Power Generation, 2016 A more modern and more flexible version of the induction generator that is used in large wind turbines is a variant called the doubly-fed induction generator. In a conventional induction generator the generator stator is connected to directly to the grid and the rotor is a closed loop coil.

How does a wind turbine work?

The ro-tor of the wind turbine is coupled to the generator shaft with a fixed-ratio gearbox. Some induction generators use pole-adjustable winding configurations to enable operation at different synchronous speeds. However, at any given operating point, this Danish turbine basically has to operate at con-stant speed.
