Wind power plant sensing system suitable for complex wind area

Abstract

The invention discloses a wind power plant sensing system suitable for a complex wind area, which comprises a database, a wind power plant control area division module, a wind power plant off-line sub-model generation module, a wind power plant real-time information sensing module and a wind power plant on-line sensing module. The output end of the database is connected with the input end of the wind power plant control area division module; the output end of the wind power plant control area division module is connected with the input end of the wind power plant off-line sub-model generation module; the output end of the wind power plant off-line sub-model generation module is connected with the model input end of the wind power plant on-line sensing module; and the output end of the wind field real-time information sensing module is connected with the information input end of the wind power plant on-line sensing module. According to the method, the real-time information of a wind power plant is used as the input of the wind power plant off-line sub-model, so that the wind power plant off-line sub-model outputs the power, the pitch angle and the yaw angle of a corresponding wind turbine generator set, on-line sensing of the wind power plant is achieved, the wind power plant control strategy can be adjusted in time, and the operation safety of the wind power plant is improved.

Description

technical field [0001] The invention relates to the technical field of wind power generation, in particular to a wind farm perception system suitable for complex wind areas. Background technique [0002] With the gradual depletion of energy sources such as coal and oil, human beings pay more and more attention to the utilization of renewable energy. As a clean renewable energy, wind energy has been paid more and more attention by countries all over the world. It is very suitable for coastal islands, grasslands, pastoral areas, mountainous and plateau areas that are short of water, fuel, and inconvenient to use wind power to generate electricity according to local conditions. Wind power generation refers to the use of wind turbines to convert the kinetic energy of wind into electrical energy. With the rapid development of my country's energy transformation and wind power technology, China's new wind power grid-connected installed capacity has increased significantly in recen...
