Problems solved by technology

[0003] In order to solve the above-mentioned technical problems, the present invention provides a method for longitudinal layout of horizontal-axis wind turbine clusters. By arranging the upstream and downstream wind turbine clusters in different rotation directions at intervals, the downstream wind turbine clusters are solved due to the influence of wake flow of upstream wind turbine clusters, especially the influence of rotational kinetic energy. The problem of the decrease of the output power of the wind turbine

Abstract

The invention discloses a horizontal shaft wind turbine group longitudinal layout method. The horizontal shaft wind turbine group longitudinal layout method includes the following steps that the arrangement direction of a horizontal shaft wind turbine group is determined; the arrangement space of the horizontal shaft wind turbine group is determined; the rotating direction of the horizontal shaftwind turbine group in the first row is determined; the rotating direction of the horizontal shaft wind turbine group in the second row is determined; the rotating directions of horizontal shaft wind turbine group in the third row and the following rows are determined. The longitudinal layout method has the advantages that on the premise of not changing an original longitudinal wind turbine group overall layout scheme and not substantially increasing manufacturing cost of wind turbine blades, generator unit and other components, rotation kinetic energy loss of upstream wind turbines is capturedby downstream wind turbines through spaced layout of the downstream wind turbine units in different rotating directions, the adverse effect on the downstream wind turbine units by upstream wind turbine units is reduced, and therefore overall wind wheel output power of the longitudinal layout wind turbine group can be improved.

Description

technical field [0001] The invention relates to the technical field of wind power generation, in particular to a method for longitudinal layout of a horizontal-axis wind power cluster. Background technique [0002] For a wind farm with a certain total area, if the interaction of wind turbines is not considered, theoretically the more wind turbines, the higher the power generation per unit volume. In practice, the mutual interference effect between wind turbines is taken into account, especially the upstream wind turbine cluster. The adverse effect of the wake on the downstream wind turbine cluster makes the layout density of the wind turbine cluster not too high. However, due to the constraints of the wind field terrain environment, construction conditions, construction costs, and total installed capacity, the downstream wind turbines often cannot completely avoid the upstream wind. The longitudinal influence area of ​​the wind turbine (about ten times the diameter of the wi...
