Optimal selection method for wind generation sets in wind power farm

Abstract

The invention discloses an optimal selection method for wind generation sets in a wind power farm. The method comprises the following steps of: (1) firstly, computing the annual equivalent full generation hours and the generating capacity coefficient of each alternative set of a proposed wind power farm, and computing difference kilowatt hour cost and full lifecycle difference kilowatt hour cost of each alternative set in the wind power farm according to a computational formula of the difference kilowatt hour cost and the full lifecycle difference kilowatt hour cost; (2) taking minimization of the expense of the kilowatt hour cost in the full lifecycle as the primary basis for making a decision, comparing the full lifecycle difference kilowatt hour cost of each alternative set, and selecting the alternative set with the minimal full lifecycle difference kilowatt hour cost as the determined set; (3) when the full lifecycle difference kilowatt hour costs of the alternative sets of different models are identical or approximate, selecting the set with lower difference kilowatt hour cost or the set with higher annual equivalent full generation hours and higher generating capacity coefficient. The method can effectively and quickly perform optimal selection on multiple models, thereby providing reliable basis for the developers to make decision on selection.

Description

technical field [0001] The invention relates to a method for optimal selection of wind turbines in a wind farm, and belongs to the technical field of wind power generation. Background technique [0002] In the unit selection stage of wind farm project planning and design, it is often necessary to consider 6 to 9, or even more than ten types of models, and it is difficult to quickly and comprehensively make investment estimates and economic evaluations for so many types of models in a short period of time. [0003] The working principle of the wind turbine is that the wind acts on the blades at a certain speed and angle of attack, causing them to generate rotational torque and turn, convert wind energy into mechanical energy, drive the generator to generate electricity through the transmission mechanism, and connect to the grid or operate independently. [0004] According to different operating characteristics and structural characteristics, wind turbines can be classified in...
