What is the appropriate wind resistance of a gasoline generator

What voltage does a wind turbine use?

A modern wind turbine is often equipped with a transformer stepping up the generator terminal voltage, usually a voltage below 1 kV (E.g. 575 or 690 V), to a medium voltage around 20-30 kV, for the local electrical connection within a wind farm (distribution level).

Do constant speed wind turbines reduce power system inertia?

The combined inertial response of a wind power plant will depend on the electrical characteristics of its individual wind turbines. Constant-speed wind turbines have different inertial response than synchronous generators; however, they do not intrinsically decrease the power system inertia because of their electromechanical characteristics.

What are the limiting factors for inertial response from wind turbines?

The main limiting factors for inertial response from wind turbines are the extra heat due to additional power generation and stress on mechanical components. The duration of inertial response is not long enough to generate thermal losses high enough to become a risk factor in the generator winding.

How much inertia can a wind turbine release?

As shown in Fig. 2, the 1.5-MW wind turbine is capable of releasing up to 200 kilowatts (kW) from inertia during 15 seconds (s) when the wind rotors slow down by 5 rpm from the initial speed. With appropriate controls, this turbine inertia can be “connected” directly to the grid.

How does rotor resistance affect power output of a wind turbine?

By varying the rotor resistance, the slip and thus the power output of the wind turbine can be controlled. The dynamic speed control range varies with the size of the variable rotor resistance and commonly reaches up to 10% above the synchronous speed. The energy coming from the external power conversion unit is dumped as heat loss.

How is wind speed used in a WG system?

In the methods presented in this chapter, wind speed is used as the input data, and then all state variables and conditions of the WG system, for example, wind turbine output, generator output, output power to the power grid, and various losses in the system etc., can be obtained.
