An optimal
site selection device for a distributed
wind power plant based on a
fuzzy analytic hierarchy process comprises a DSP (
Digital Signal Processor) module, a keyboard input module, a
liquid crystal display module, a communication module and a host computer. An optimal
site selection method for the distributed
wind power plant based on the
fuzzy analytic hierarchy process comprises the following steps: dividing candidate wind energy resource zones in a region rich in wind
energy resources, determining an evaluation
index system for the
site selection of the
wind power plant, determining the hierarchical structure of a scheme for the site selection of the wind power plant, judging the
cognition degrees of experts on selected sites for the wind power plant by an
expert group judgment and group decision method to obtain the
cognition degree parameters of all the experts, and constituting a criterion layer judgment matrix and an index layer judgment matrix for the site selection of the wind power plant; and finally
ranking the candidate wind energy resource zones by advantages and disadvantages and determining one site for the wind power plant. Compared with the traditional
analytic hierarchy process for site selection, the method has the advantages that factors are fully considered, the examination and the regulation of the consistency of the judgment matrixes are simple, easy, scientific and reasonable, and results are scientifically analyzed. The device has the advantages that through the operation
processing process of the DSP, the site selection period can be shortened, and the site selection efficiency can be increased.
