Are switched reluctance generators suitable for wind energy conversion?

Switched reluctance generators (SRGs) are suitable candidates for wind energy conversion systems, as they present a simple structure, robustness, a wide range of speed and are capable of operating in harsh environments. The machine, however, poses challenges such as high torque ripple, acoustic noise production and highly nonlinear behavior.

How does a wind generator work?

The anemometer detects the wind speed, the wind vane detects the wind direction and performs the yaw operation. When the wind speed reaches the power-on value, the pitch system starts to work, and the blades are changed to an appropriate angle according to the wind speed. The speed sensor detects the speed of the fan and the speed of the generator.

How do wind turbines work?

Large wind turbines are directly connected to the grid for operation. Therefore, the wind turbines must be installed in one place to form a scale, which is called a wind farm. There are two different types of wind power generation, namely: stand-alone operation – off-grid and connected to the power system – grid-connected.

What does the wind energy technologies office do?

The Wind Energy Technologies Office invests in wind energy science research and development activities to enable greater use of abundant domestic wind resources for electric power generation that will help stabilize energy costs, enhance energy security, and improve our environment.

How does a wind farm work?

When the voltage reaches the on-grid condition, the inverter executes the on-grid operation, enters the booster station, and enters the grid. Large wind turbines are directly connected to the grid for operation. Therefore, the wind turbines must be installed in one place to form a scale, which is called a wind farm.

What is off-grid wind power generation?

Off-grid wind power generation is small in scale and can solve the power supply problem in remote areas through energy storage devices such as batteries or in combination with other energy generation technologies (such as wind power/hydropower complementary systems, wind power-diesel unit combined power supply system).
