Abstract

The invention discloses a fan output power prediction method, which comprises the following steps of: firstly, establishing a multivariate polynomial regression model based on a maximum information coefficient and multivariate polynomial regression; and then, determining a test set, and predicting the output power of the fan on the test set by using the multivariate polynomial regression model. In addition, the invention further provides a fan output power prediction system. According to the method and system, the maximum information coefficient is used for selecting the important variables influencing the output power of the fan in the process of establishing the multivariate polynomial regression model, multiple important variables are comprehensively considered, the problem that analysis is not comprehensive enough due to the fact that influence factors of the output power of the fan are analyzed manually is solved, and further, the relation between multivariable and the fan output power is modeled through a polynomial method, so that prediction of the fan output power has high accuracy and low model complexity.

Description

technical field [0001] The invention relates to the field of electric power, in particular to a method and system for predicting the output power of a fan. Background technique [0002] The use of wind energy in new energy has a great role in promoting economic development. Therefore, it is of great significance to accurately predict the output power of wind turbines. The traditional wind power forecasting method is to use the wind turbine power curve (WTPC) model provided by the manufacturer. However, this model only shows the relationship between the wind turbine output power and wind speed, without considering the influence of factors such as wind direction, rotor speed and pitch angle, which has certain limitations. In addition, in the process of predicting the output power of wind turbines, it is necessary to use a multivariate regression model, but the factors that affect the output power of wind turbines are different in different wind farm environments. How to deter...
