The Design And Implementation Of Optimization Scheduling System Of Cascade Pump Station

With the increasing economic growth of our country,people's demand for water resources is increasing continuously.In addition,many urgent problems that are faced by the uneven distribution of water resources due to the geographical environment factors in China are coming up.The large-scale cascade pumping stations water diversion project arises at the historic moment.With the establishment and operation of long distance and large scale cascade pumping stations,the problems in actual operation are becoming more and more obvious.In the actual production operation of pumping station,often due to scheduling personnel decision making is defective,flow convergence between the lower cascade pumping stations properly,resulting in waste water,waste,energy flow,pumping operation disorders,what is more,will cause major accidents occurred.At the same time,due to the long running time of the cascade pumping stations,the huge cost of operation and the large energy consumption,the problem of optimal operation of cascade pumping stations is attracting more and more attention.In order to solve the above problems:(1)the analysis and the optimization of the optimal scheduling algorithm for cascade pumping stations.Firstly,inter-stage optimization,with the lowest operating cost as the objective function is established between the optimization mathematical model,using linear programming method is used to calculate the optimal flow;then describes the pumping station optimization,in order to minimize the energy consumption as the goal of establishing a single station optimization mathematical model,find out the best combination of single station boot,contains the boot the unit type and the various types of turbine units.At last,a nine stage pump station is taken as an example to solve the mathematical model according to the actual working condition data.(2)according to the requirement of determining the design goal of software,the overall design of software system is carried out,and the optimal dispatching system of cascade pumping stations based on J2 EE technology framework is developed.(3)describe the interface test of software,the test of the optimization module and the comparison of the data before and after the optimization.The innovation of the thesis is that at present,most of the optimal operation of cascade pump stations only consider the optimal operation of a pump station or the optimal operation of a single stage pump station without a cascade,without considering the optimal operation of cascade stations.At the same time,this paper combines the optimization of the inter-level and the station,and maximizes the optimization effect.The thesis is starting from the optimization of inter-stage and the optimization of single station,taking the minimum operation cost and minimum energy consumption as the operation objectives,developed a cascade pump station optimal scheduling system based on technical architecture of J2 EE based on linear programming algorithm.The system can make the water flow distribute evenly,which is beneficial to reduce the occurrence of abandoned water or cut off,and also reduce the operation cost and energy consumption of the pumping station.It has a good application prospect.
