阿根廷基什内尔总统水电站发电机性能参数及结构特点

Performance Parameters and Structural Characteristics of Generators at the Nestor Kirchner Presidential Hydroelectric Power Station

阿根廷基什内尔总统水电站装设5台额定功率为190 MW的混流式水轮发电机组,在电力系统中承担发电、调峰和调相功能,是“一带一路”在南美地区的标志性工程。国外咨询工程师对水轮发电机的频率变化范围、额定电压和槽电流、短路比和纵轴同步电抗、冷却方式、消防方案等技术参数和结构要求与国内标准和习惯不同,通过比较分析相关国内外标准规范和类似水电站发电机参数水平,对水轮发电机性能参数和结构特点进行总结和概括,供类似水电站发电机选型和设计参考。

The Nestor Kirchner Presidential hydroelectric power station in Argentina is equipped with five Francis turbine-generator units,each rated at 190MW.These units play crucial roles in power generation,peak regulation,and phase modulation in the power system.It is a landmark project for the Belt and Road Initiative in South America.The foreign consulting engineers have different technical parameters and structural requirements for the frequency variation range,rated voltage,slot current,short-circuit ratio,direct axis synchronous reactance,cooling methods,and fire protection schemes of the hydraulic turbine generators compared to domestic standards and practices.By comparing and analyzing relevant domestic and foreign standards and similar hydroelectric power station generator parameters,this paper summarizes and generalizes the performance parameters and structural characteristics of turbine generators,providing a reference for the selection and design of similar hydroelectric power station generators.
