Wind power prediction system for wind power plant, and realization method

Abstract

The invention discloses a wind power prediction system for a wind power plant. The wind power prediction system focuses on the actual applications of the wind power plant, combines specific requirements in the aspects of actually-measured data, prediction power amendment and report, safety and the like, and comprises five parts of an anemometer tower, an SCADA fan data monitoring device, an external network server, a reverse isolation device, an internal network server, wherein the anemometer tower and the SCADA fan data monitoring device are connected to the external network server by a data transmission line, and the external network server is connected with the internal network server by the reverse isolation device on the basis of the safety of the wind power plant; a data acquisition function unit and an SQL acquisition database are installed on the external network server, and a power prediction function unit and an SQL prediction database are installed on the internal network server. The system supports user level and permission settings, all the data is stored in the databases, all forms and curves are provided with the functions of printing output and spreadsheet output simultaneously, and various prediction models are embedded, and the prediction accuracy can be increased by selecting the different prediction models in different wind power plants or different seasons.

Description

technical field [0001] The invention relates to a wind power forecasting system and a realization method of a wind farm, belonging to the application field of new energy wind power generation. Background technique [0002] Wind energy is a renewable energy that does not pollute the environment. As the main form of energy in the future, it is of great significance to the way of life, survival and development of human beings in the future. In order to effectively utilize wind energy resources, the grid-connected operation of large wind farms needs to be equipped with a wind power forecasting system. If there is no support from the forecasting system, or if the forecast is not accurate enough, the wind farm may be subject to power rationing, resulting in the effective installed capacity of the wind farm not being fully utilized. The accuracy of wind power forecasting is directly related to the balance of supply and demand of the power grid, and directly affects the operating c...
