Piecewise linear dispatching method facing water diversion system of multi-source cascade pump station

Abstract

The invention provides a piecewise linear dispatching method facing a water diversion system of a multi-source cascade pump station. By utilizing the parameters, such as the available water supply quantity of a reservoir, the water demand of each water user in the system, the design flow of the pump station, the maximum and minimum reservoir capacity, the maximum discharge capacity, etc., the water distribution rules of each water user and the operation rules of the pump station and reservoir in the system are optimized, and finally a dispatch rule is obtained, water consumption of the water users and the water diversion quantity of the pumping stations and reservoir are generated as the bases for guiding the operation of the system. The method of the present invention overcomes the unnecessary energy consumption of the pump station caused by the experience in the traditional water transfer process, gives priority to the use of the local water source and the short-distance water source, improves the water diversion and water supply efficiency, has clear theoretical significance, is simple and easy to operate, and is easy to be applied in the actual water transfer.

Description

technical field [0001] The invention relates to the field of management and scheduling, in particular to a segmented linear scheduling method for a multi-water source cascade pumping station water transfer system. Background technique [0002] With the increasingly prominent regional water shortage problem, the construction of large-scale cross-basin water diversion projects has become an important engineering means to solve regional water shortage. As a major measure to optimize the allocation of water resources between regions and promote sustainable and balanced economic and social development, how to minimize the operating costs of water transfer projects while ensuring the water supply needs of water users is the core technical issue in the operation of water transfer systems. [0003] The operation mode of the traditional water diversion project is multi-level dispatching. The high-level department formulates the general dispatching plan, and the operators of the sub-l...

Problems solved by technology

[0004] In this traditional scheduling mode, the high-level department decomposes the total water transfer target and the total water supply target into each pump gate station, and each pump gate station formulates a dispatch strategy based on the allocation index. This hierarchical dispatching method often lacks support. The systematic analysis of the water balance relationship between the various hydraulic units results in low operating efficiency of the dispatching system and unnecessary energy consumption of pumping water
