摘　　要：抽水蓄能电站机组背靠背启动是保证电站机组可靠运行的重要手段。因其涉及两台机组多个系统的协调配合,十分复杂,导致部分电站机组启动成功率不高。该文结合国网新源公司部分抽蓄电站机组背靠背启动失败的案例,分析了其失败的主要原因,并提出了相应的改进措施,为机组背靠背启动的进一步深入研究提供了有益的参考。Back-to-back start-up of pumped-storage power station unit is an important means to ensure the reliable operation of the unit.Because it involves the coordination and cooperation of multiple systems of two units,it is very complex,resulting in the low start-up success rate of some power station units.Combined with the cases of back-to-back startup failure of some pumping and storage power plants in State Grid Xinyuan Company,this paper analyzes the main causes of the failure,and puts forward the corresponding improvement measures,providing a useful reference for the further research of back-to-back start-up of units.
