The embodiment of the invention provides a method and device for determining fan distribution in a wind power plant, and the method comprises the steps: determining an integer constraint condition and an objective function of an integer programming model according to the number of fan lines, the number of fans, the active power of each fan line and the active power of each fan in the wind power plant; according to a preset integer programming branch and bound rule, determining a value corresponding to each coefficient meeting the integer constraint condition in the target function, determining a serial number of a fan connected to each fan line, and obtaining fan distribution in the wind power plant; according to the method, the fan distribution in the wind power plant can be accurately and conveniently determined.
Description
technical field [0001] The application relates to the field of data processing, in particular to a method and device for determining the distribution of fans in a wind farm. Background technique [0002] In recent years, the installed capacity of wind turbines in my country has grown rapidly. In order to improve the consumption level, it is necessary to further improve the prediction accuracy of wind power generation power. When predicting the power generation of a wind farm, it is necessary to calculate the line loss in the field according to the fan distribution structure to further improve the accuracy. However, some wind farms cannot provide relevant materials for the fan distribution structure. [0003] In order to solve the problem that the wind farm cannot provide the fan distribution structure, the method adopted in the prior art is mainly the enumeration method. The enumeration method calculates the distribution of fans inside the wind farm according to the power g...
