风电场设计中电压设定的探讨

Study on Voltage Setting in Design of Wind Power Plant

风力发电作为可再生清洁能源,在中国电力发展战略中的作用日益凸显,设计高效、稳定、精准控制的风电场在风电建设中的利刃尖兵作用更为突出。而电气设计是整个风电场设计工作中最为重要的部分。基于多个在建和已建的风电场工程设计经验和运维效果,针对风电场主变压器、箱式变压器及站用变压器的变比、电压等级、集电线路的电压设定等风电场特殊问题,分析总结了一些方案理念,为今后风电场设计和运维更合理可靠提出了自己的见解。

As the renewable clean energy,function of wind power development in strategy of China’s electric power development highlights increasingly.In wind power construction,it is critical to design a high-efficiency,stable and precisely controlled wind power plant.But the electric design is one of important part in design of the whole wind power plant.Based on experience on design of several built wind power plants and of operation and maintenance effect,some proposals are analyzed and concluded in terms of ratio and voltage grade of main transformer,box transformer and service transformer,and voltage setting of collection line,etc..These provide more reasonable and reliable design and O & M of future wind power plant with personal interpretation.
