风电场采用非晶合金变压器设计探讨

A Discussion on the Design of Amorphous Transformer for Wind Farm

非晶合金具有极优秀的低损耗磁特性,把非晶合金变压器这一新兴产品更全面地应用于风电建设项目,可利用其优良的损耗特性产生可观的经济效益和巨大的节能减排效益,从而满足工程建设和环境保护的共同需求。通过对福建省长乐棋盘山等近20个风电项目的调查,以装机容量50 MW的某风电场为例,对其6类变压器的技术指标进行分析,将筛选出的具备使用条件的变压器更换为非晶合金变压器,结合全寿命周期成本理论分析,认为采用非晶合金变压器具有较明显的技术经济优势,同时也具有突出的环保效益。

An excellent magnetic property of amorphous alloy is low losses. The wider use of amorphous alloy for wind farm projects could result in meaningful economic value and significant benefits in energy conservation and emission reductions, therefore meets the dual requirements of the project construction and the environment protection. Based on an assessment of about 20 wind projects located in Changle Qipanshan wind farms in Fujian Province, the study analyzes 6 different kinds of transformers based on a 50 MW wind farm. The transformers that maintained workable conditions are then replaced with amorphous alloy transformers. The life cycle cost analysis indicates amorphous alloy transformers have obvious techno-economic advantages as well as outstanding environmental benefits.
