基于可变云模型的南水北调中线水力调控综合评价OA

[Objective]This study conducts a comprehensive evaluation of the hydraulic regulation of the South-to-North Wa-ter Diversion Middle Route Project(SNWD-MRP)to provide scientific support for precise scheduling decision-making.[Methods]Considering factors such as water level control objectives,water level decline constraints,gate regulation fre-quency,and response time,a hydraulic regulation evaluation system for the SNWD-MRP was established.A variable cloud comprehensive evaluation model based on a triangular distribution was developed through the integration of variable fuzzy set theory and cloud theory.Ten typical hydraulic regulation schemes for water transfer of the SNWD-MRP were evaluated and se-lected.[Results](1)Scheme 3 was relatively the best,with a comprehensive grade value of 2.76 and an evaluation grade of good.Scheme 6 was relatively the poorest,with a comprehensive grade value of 4.09 and an evaluation grade of relatively poor.(2)The evaluation grade of most scheduling schemes was average,and the comprehensive grade values were between 3.02 and 3.52,which reflected the conflict among different evaluation indicators.(3)The ranking results showed that safety-critical indicators,such as water level thresholds and fluctuation controls,had a significant influence on the evaluation of the schemes,which was consistent with the safety-first principle in the operation scheduling of the SNWD-MRP.[Conclusion]The variable cloud comprehensive evaluation model can effectively quantify and evaluate various scheduling schemes,and rank them accordingly.In the future,combined with the construction of digital twin technology,further re-search on the optimization and real-time control of regulation models can be conducted to provide technical support for intelli-gent scheduling of the SNWD-MRP.
