Wind power with its clean, pollution-free, renewable and other characteristics, by the world's attention and focus on development. It is estimated that the world has 20 gigawatts of wind energy available, about 10 times more than hydropower. If one percent of wind energy is used, eight to nine percent of the world's current electricity generation could be generated. It is estimated that China's exploitable wind energy resources are about 1.6 billion kilowatts.

Wind power generation is bound to become an important measure to solve the energy problem. However, because of the uncontrollability of wind power, the instability and intermittency of wind speed determine that the output of wind turbine is also characterized by volatility and intermittency. From the point of view of grid connection, how to ensure that the input power of wind turbine connected to grid is within the power grid is the key to solve the problem of wind power connected to grid.

In order to ensure that the grid-connected input power of the wind turbine is within the grid bearing power, it is required to carry out load distribution design for the wind turbine. That is, when the output power of the wind turbine is greater than the grid bearing power, the corresponding load distribution load will consume the excess power to ensure that the grid-connected requirements are met. When the output power of the wind turbine meets the requirements of grid-connection, the stowed load no longer consumes power to ensure that the output power of the wind turbine is fully integrated into the grid and the utilization rate is improved.

In view of the characteristics of wind power generation, its output voltage range is wide, and the general wind power station is designed in the field, there is no external working power supply, and the stability of the power grid is guaranteed, which requires that the load of the wind turbine has the characteristics of wide power input range, quick response, and accuracy of monitoring.

Compared to traditional loads:

1. The working power of traditional load generally adopts power supply from power grid. As wind farms are generally located in sparsely populated areas with special geographical location, they rarely set up external power supply, which brings some troubles to the use of load.

2. In order to expand the working power range of some traditional loads, UPS is used to supply power to load devices. This not only increases the load volume, greatly increases the purchase cost of load equipment, and with the increase of installed capacity of large wind turbines, the capacity of UPS will also be a test.

3. The traditional load is generally used for the load performance test of the generator set, and its response speed cannot meet the load requirements of the wind turbine.

Kai Xiang wind turbine load, dedicated to the load of wind turbine. The use of international advanced components, strong anti-fluctuation ability, a wide range of application.
