基于系统协调度模型的汛限水位分期控制
Staged Control of Flood Limit Water Level Based on System Coordination Degree Model
摘要
Abstract
To coordinate between flood control and profit promotion and enhance the efficient utilization of flood re-sources,we proposed a stage-based division of flood season using the improved fuzzy set method,and subsequently established a system coordination degree model to calculate the dynamic control domain of flood limit water level.The limit water levels in Silin Reservoir,as an example,in pre-flood season and post-flood season are directly pro-portional to the synergetic contribution degree of power generation benefit,but inversely proportional to the syner-getic contribution degree of flood control risk.To achieve the maximum degree of system coordination,the dynamic control domain of flood limit water level is recommended to be[435,437]m and[435,438]m in pre-flood season and post-flood season,respectively.These recommendations would lead to additional electricity generation of 2 169.907×104 kW·h and 6 509.722×104 kW·h,and an increase in water resources utilization of 0.716×108 m3 and 1.079×108 m3,during the pre-and post-flood seasons,respectively.The findings of this study contribute to im-proved flood resource utilization and offer valuable insights for the safe and reasonable operation of reservoirs.关键词
