: Luding hydropower station is located near the earthquake fault zone and is badly affected by earthquake disaster, which may cause dam and gate structure deformation, power interruption, gate blocking and other potential risks. Sometimes, there is rainstorm after earthquake which may cause flood. Therefore, normal operation of the gate, and sometimes larger lifting force are needed. In view of the impact of earthquake, by analyzing the existing emergency measures of Luding hydropower station, a more suitable non- electric hydraulic controlled emergency operator is selected as an improved emergency plan. Through adoption of the non-electric hydraulic controlled emergency operator, the emergency opening ability of the flood sluice of Luding hydropower station is improved, which is of great significance.
