风电场箱式变电站设计选型要点分析

Analysis of Key Points on Design Points of Wind Farm Box-type Substation

为统一风电场箱式变电站变压器及箱变低压侧动力电缆的设计原则,形成标准化的设计方案,文章梳理并分析相关设计标准与规程规范,针对变压器的型式、容量和能效,以及箱变低压侧动力电缆的材料、根数和截面积,提出了设计方案与选型计算的依据,通过工程实例验证了标准设计方案的合理性与适用性,最后提出风电场箱变选型的注意事项。

In order to unify the design principles of wind farm box-type substation transformers and low-voltage cables and form a standardized design scheme,the article combs the relevant design standards and regulations,aiming at the type,capacity and energy efficiency of transformers,as well as the material,number and cross-section of lowvoltage cables,put forward the standard design scheme and selection calculation basis,and verified the rationality and applicability of the standard design scheme through two engineering examples.
