Abstract

Provided is a wind farm design and optimization method and system. The wind farm design and optimization method and system belongs to the technical field of wind farm design. The method includes S1, generating a wind farm ideal matrix according to wind resource conditions of a wind farm; S2, adjusting the wind farm ideal matrix according to boundaries and terrain of the wind farm to obtain a wind farm actual matrix; S3, obtaining wind farm generating capacity of different wind generator row and column arrangement corresponding to the wind farm actual matrix to obtain the wind generator row and column arrangement at the maximum generating capacity as initially optimized wind farm arrangement; S4, moving the row and column of a wind generator with the highest impact on wake flow to achieve the maximum generating capacity; S5, moving the wind generator with wake flow difference greater than a predetermined threshold due to different predominant wind directions in different seasons to achieve the maximum generating capacity; S6, outputting the final optimized wind farm arrangement and the corresponding generating capacity of the wind farm.

Description

technical field [0001] The invention relates to the technical field of wind farm design, in particular to a method and system for wind farm design and optimization. Background technique [0002] The micro-site selection of wind farms is an important link in the construction of wind farms. A reasonable wind farm layout can not only increase the output of the entire wind farm, but also ensure the reliability of the unit. The upstream wind turbines will have wake effects on the downstream wind turbines during operation, and one wind turbine will be affected by the wakes of multiple wind turbines. The wake not only affects the output of the entire wind farm, but also increases the load of the unit, which in turn affects the service life of the unit. The main function of wind farm micro-site selection is to minimize the impact of wake on wind farms by rationally distributing wind turbines. [0003] At present, two commonly used wind turbine arrangement methods are uniform arra...
