6月14日，甘肃刘家峡水电厂3号机组归调加运，标志着3号机组整机改造圆满完成并投产发电。至此，该厂年度主设备检修全面结束，8台水轮发电机组全部投入运行。刘家峡水电厂3号机组整机改造比计划工期提前16天完成。改造人员先后完成旧水轮发电机组分解、拆除，新水轮发电机组安装调试和加装出口断路器等工作。此次3号机组整机改造实现一次性启动成功且零缺陷高质量投产发电，经试验各项数据均优于国标要求，机组稳定运行区间由160至260兆瓦提升至100至260兆瓦，提升幅度81%，机组顶峰调峰能力显著增强。

On June 14, Unit 3 of Gansu Liujiaxia Hydropower Plant returned to operation, marking the complete transformation of Unit 3 and put into production. At this point, the annual maintenance of the main equipment of the plant has been completed, and all 8 water turbine generators have been put into operation. The transformation of Unit 3 of Liujiaxia Hydropower Plant was completed 16 days ahead of schedule. The reconstruction personnel have completed the decomposition and dismantlement of the old turbine generator set, the installation and debugging of the new turbine generator set and the installation of the outlet circuit breaker. The transformation of the No. 3 unit to achieve a one-time successful start and zero defects high-quality production of power generation, the test data are better than the national standard requirements, the stable operation of the unit from 160 to 260 MW increased to 100 to 260 MW, an increase of 81%, the unit peak peak load capacity significantly enhanced.
