The generated power of each generated power sequence is identified as a corresponding rotation speed-torque combination according to the rotation speed and torque value of the generated power sequence. This is accomplished by looking up corresponding rotational speed and torque values in the map and using these values to identify the generated power in the generated power sequence. After the mapping relation between the rotating speed and the torque is obtained, a nonlinear relation exists between the rotating speed and the torque. Therefore, the nonlinear mapping relation is required to be used for identifying the generated power in the generated power sequence more accurately, the nonlinear mapping relation is subjected to linear processing, performance peak search is respectively carried out on N wind power devices based on N generated power sequences, and a data base is provided for generating N optimal rotation speed-torque mapping values according to N search results.

These target search particles may represent optimal speed-to-torque map values for a given sequence of generated power, with N optimal speed-to-torque map values being generated from N search results. The rotation speed-torque mapping value can be further analyzed and optimized by comparing the particle density of the gravity centers of the N mapping particles with the particle density of the N searching particles and judging whether the current mapping particles need to be updated.

The environmental impact information is corrected through the first evaluation result and the second evaluation result, so that the environmental impact information can be more accurate.
