Research Progresses and Frontiers on Control and Safety Operation of Super-large Hydraulic Complex

For a super-large hydraulic complex, comprehensive regulation is complicated due to flood control, power generation and ship navigation and it is difficult to ensure security of complex in this situation. In order to solve the safety operation problems, this paper summarizes hot spots and frontier research in this field on the basis of research progresses and engineering practice in the world. It mainly includes: hydraulic disaster-causing mechanism of high speed flow, high pressure transient flow and high head seepage; performance attenuation of dam and reservoir banks for life cycle, real-time measurement and control technology of multiple factors considering coupling effects on safety operation , safety evaluation theory with multiple information fused; rainstorm flood forecasting and emergency control technology for hydraulic complex groups; real-time safety operation control technology for flood discharge; safety and intelligence operation technology of hydro-power system; combined optimal control technology of power generation, flood discharge and ship navigation; risk control and security technology in the initial stage of operation of hydraulic complex; long-term operation technology for safety of high dam structure and stability of reservoir bank under the complicated operating conditions. The technological research in this field should be enhanced to satisfy the demands of long-term safety operation for large hydraulic complex.
