摘　　要：瀑布沟、深溪沟、枕头坝三站由于特殊的接线方式和地理位置,在三站AVC投闭环控制,经常出现三站电压设值不合理,引起机组欠励或过励现象,笔者结合事例,叙述其故障过程,分析故障原因,提出采用区域电压联合调节手段解决该现象。在流域梯级电站智慧调度建设中,区域电压联合调节意义重大,控制着电压质量和提高电压合格率、梯级电站运行管理水平,为实现电站运行安全、经济、优质、高效发挥巨大作用。Due to special connection method and geographical location of Pubugou Hydropower Station,Shenxigou Hydropower Station,and Zhentouba Hydropower Station,unreasonable voltage settings at the three hydropower stations often appear in the closed-loop control of AVC,causing under-excitation or over-excitation of the generator units.Taking into consideration real cases,the author describes the failure process,analyzes the causes of failure,and proposes the use of regional voltage joint adjustment methods to solve the phenomenon.Joint regulation of voltage in a region is of great significance in intelligent dispatching of cascade power stations in the river basin.It controls voltage quality,improves the voltage qualification rate and the operation and management level of cascade power stations.Moreover,joint regulating of voltage plays an important role in achieving safe,economic,high quality,and efficient operation of power stations.
