Method and system for integrally optimizing electrical design scheme of wind electric field

Abstract

The invention provides a method and a system for integrally optimizing an electrical design scheme of a wind electric field. The method comprises the steps of: performing electrical design on the wind electric field based on obtained electrical design data, specifications and standards of the wind electric field; obtaining an initial electrical design scheme; calculating reliability and economic indexes based on the obtained electrical design scheme; optimizing the initial electrical design scheme by utilizing the reliability and the economic indexes to obtain the optimized electrical design scheme of the wind electric field; finally, synthesizing the optimized electrical design scheme of the wind electric field based on the current running environment of the wind electric field, and performing integral optimization on the electrical design scheme of the wind electric field. The electrical design scheme of the wind electric field is optimized by fully considering the characteristics of the wind electric field, optimizing the initially obtained electrical scheme by utilizing the reliability and the economic indexes of each constituent component of the wind electric field after the initial electrical design scheme is obtained, and combining the electrical design, the reliability evaluation and the economic evaluation together.
