Wind power induction generator enterprise share

What is a modern induction generator wind power system?

The core component of a modern induction generator wind power system is the turbine nacelle, which generally accommodates the mechanisms, generator, power electronics, and control cabinet. The mechanisms, including yaw systems, shaft, and gear box, etc., facilitate necessary mechanical support to various dynamic behavior of the turbine.

What are the classifications of induction generator wind systems?

The most promising classifications in induction generator wind systems are fixed-speed, limited-variable-speed, and variable-speed wind systems, according to the operations of induction generator speed. Comparisons between these wind power systems have been intensively conducted, based on different speed variation levels [12, 15 - 19].

How many types of induction generators are there?

Generally, there are two types of induction generators widely used in wind power systems – Squirrel-Cage Induction Generator (SCIG) and Doubly-Fed Induction Generator (DFIG). The straightforward power conversion technique using SCIG is widely accepted in fixed-speed applications with less emphasis on the high efficiency and control of power flow.

Why do we need induction machines for wind power generation?

Advanced manufacturing and assembly techniques are imperative in order to achieve the optimal performance of electric machine–drive systems for energy conversion, as well as avoid any potential failures. Development of induction machines for wind power generation naturally results in larger machine ratings and size.

What is the global wind turbine market share?

Figure 1: Global Wind Turbine Manufacturers' Market Share by Take-in-Orders 2022 (GW) Source: Enerdata (Data derived from companies’ annual reports) Enerdata’s statistics show that Goldwind, a Chinese manufacturer, increased its in-take-orders from 10.7 GW in 2021 to 20.8 GW in 2022, a year-over-year growth of 94%.

Which induction generator is most popular in 2021?

The double-fed induction generator (DFIG) remains the mainstream solution in 2021 with 50% of the market share, followed by direct drive permanent magnet generator (DD PMG), squirrel cage induction generator (SCIG,) and medium-speed PMG.
