Research on the Application Prospects of 66kV System in New Energy Wind Power Projects

LI Taobo

[Abstract]With the implementation of the "3060" carbon peak and carbon neutrality goals， large capacity wind power bases will continue to emerge. In the future， the single unit capacity of wind turbines will become larger， and the collection line will adopt a 66 kV voltage level. Due to its advantages in investment and energy loss， it will be an inevitable trend for the development of wind farms. The article analyzes the economic feasibility of 35 kV and 66 kV collector lines in order to provide reference for relevant personnel.

1 项目研究背景

随着风机单机容量不断增大，风电场集电线路电压选择很大程度上会影响到风电场的建设运营成本，不同集电线路电压等级风电场网架结构、损耗、电气设备配置均不同，风电场建设运营成本存在很大差异。（剩余3266字）
