Variable-Speed Control Simulation Study of Water Supply Pumping Station Based on MATLAB

以模型通用、节能减排为目标,以MATLAB中的SIMULINK为仿真平台,用模块化的建模思路取代利用计算机汇编语言编程模拟的繁琐过程,实现对供水泵站并联管路系统变速节能调节的仿真计算,并运用MATLAB强大的图形绘制功能实现泵站变速运行的曲线绘制和分析,重点构建供水系统变速调节的仿真模型。通过工程实例计算,验证了仿真模型的正确性。

On the basis of study in the variable-speed control simulation of the water pumping station both at home and abroad, this paper was ai- ming at achieving a high model applicability and energy conservation and emissions reduction of parallel pipeline system and a simulated calculation of variable-speed adjustment universally and conveniently, using powerful MATLAB＇ s drawing function to realize the variable-speed control of pipe- line for pump curve plotting and research. In this study, we used SIMULINK simulation platform in MATLAB and modular modeling thought, tak- ing place of the complicated process of computer assembly language programming simulation. The key point was to build variable-speed adjustment model for the pipeline system. Through those experiments and living examples, we had verified the correctness of the model.
