Wind energy forecasting system for wind power plant

Abstract

The invention provides a wind energy forecasting system for a wind power plant. The wind energy forecasting system comprises a wind energy data acquisition system, a data transmission system and a data processing and forecasting system, wherein the wind energy data acquisition system is connected with the data processing and forecasting system through the data transmission system. By the wind energy forecasting system, wind power generation can be effectively forecast, the scheduling plans of various types of power supplies can be made for power grid height departments, so that the ration of wind power is reduced; and therefore, the capacity of a power grid for digesting and absorbing the wind power can be greatly improved.

Description

technical field [0001] The invention belongs to the field of wind energy forecasting for wind farms, and in particular relates to a wind energy forecasting system for wind farms. Background technique [0002] As a clean and renewable energy, wind energy has been paid more and more attention by countries all over the world. Its reserves are huge. The global wind energy is about 2.74×109MW, of which the usable wind energy is 2×107MW, which is 10 times larger than the total amount of water energy that can be developed and utilized on the earth. The wind has been used by people for a long time-mainly through windmills to pump water, grind flour, etc., but now, people are interested in how to use wind to generate electricity. [0003] Attempts to utilize wind power generation have already begun as early as the beginning of the 20th century. In the 1930s, Denmark, Sweden, the Soviet Union and the United States applied the rotor technology of the aviation industry and successfull...

Problems solved by technology

[0005] However, due to the problem that the active power of wind power is unstable with the size of the wind force, the active power of wind power has certain fluctuations.
