Abstract

The invention relates to a fan optimization arrangement method based on binary particle swarm optimization (BPSO), and aims to solve the problem of fan optimization arrangement of an irregularly-shaped wind field. The method comprises the following steps of: acquiring weather and geographical conditions of a wind field to be optimized and fan parameters to be selected; determining an optimized target and optimized constraint; dividing grid of a rectangular region; compiling an effective position array matrix corresponding to the shapes of the grid and the wind field, wherein in the effective position array matrix, each element is set as 1 or 0, 1 means a position at which a fan can be arranged, 0 means a position at which the fan cannot be arranged, the position at which the fan cannot bearranged is opposite to a place where the geographical condition is not suitable for arrangement of the fan in the wind field region and places outside the wind field region; constructing a solution space according to design variable to be optimized, looking for an optimal fan arrangement scheme in the solution space by adopting the BPSO according to a target function, optimizing and thus obtaining the optimal fan arrangement scheme.

Description

technical field [0001] The invention relates to the technical field of wind power generation in the machinery industry, in particular to a method for optimal arrangement of wind turbines based on a binary discrete particle swarm optimization algorithm, which can solve the problem of optimal arrangement of wind turbines in wind fields with irregular shapes. Background technique [0002] With the continuous increase of energy demand and the continuous heating up of wind power development, the preliminary planning and development of wind farms have received more and more attention. The optimal layout of wind turbines is a key link in the preliminary planning of wind farms, which directly affects the utilization rate of wind resources, the utilization rate of land resources, and the economic level of wind farms. For a wind farm with a given total land area, if the interaction of the wake of each fan is not considered, the more fans are arranged, the greater the total power gener...
