摘要:
汛期运行水位实时动态控制是协调水库防洪与兴利矛盾的一条有效措施。本文采用风险分析法推求了安康水库汛期运行水位动态控制域，建立了考虑洪水预报信息的汛期运行水位实时动态控制模型，并采用防洪风险和兴利效益相结合的多目标综合评价指标体系，优选出了安康水库汛期运行水位动态控制方案。结果表明：实时动态控制方案在不降低原防洪标准的前提下与常规调度相比，在前汛期、主汛期和后汛期7日增加的发电量分别为2.94 MKW·h (2.88%)、1.99 MKW·h (1.65%)和2.98 MKW·h (2.67%)，效益增加较为显著。
Dynamic control of reservoir water level during flood season is one of the effective measures to solve the conflict between flood control and power generation. The dynamic control bound of water level for the Ankang reservoir is derived by risk-analysis based method, and dynamic control of water level operating scheme by considering flood forecasting information is established in this paper. By using multi-objective evaluation system which considers flood risk and power generation benefit, the dynamic control of water level operating schemes is proposed for the Ankang reservoir. Compared with the designed operation scheme, it is shown that the proposed scheme can increase hydropower generation by 2.94 MKW·h (2.88%), 1.99 MKW·h (1.65%) and 2.98 MKW·h (2.67%) in the pre-flood season, main flood season and post-flood season (7 days) without reducing flood control standards, respectively.
