摘　　要：发电厂主变压器分接头的选择研究、接入点的电压水平的合理确定,对宏观系统电压的调整以及对区域无功电力的平衡具有重要的意义。国内工程主变压器分接头选择已很成熟,但国外工程还需根据外方特殊要求合理选择变压器分接头。以某国外工程为例,应用ETAP软件进行了变压器分接头选择计算,主变压器留有备用分接头,变比选择为(225±10×1.5%)/20,计算结果可以很好地满足母线电压和发电机组出力的要求。The selection of transformer taps in power plant ,the decision of reasonable voltage level of connecting node are important on voltage adjustment of the macro power system and the balance of regional reactive powers. Main transformers taps selection in domestic projects are widely applied while have to follow the special requirements in overseas projects. Taking a project from abroad for example, transformer selection calculation has been made by ETAP software . The main transformer remains back-up taps and the ratio is （225±10× 1.5%）/20. The calculation results meet the requirements of the bus voltage and the generator output.
