The climate's dependence requires a complex modelling and other optimization methods for the control of the hybrid system. Moreover, recently, and as for both the technological progression of the hardware and software, researchers may more and more optimize problems through the use of enabled platforms. The paper aims to discuss this issue. Our hybrid pumping installation contains a photovoltaic generator, a wind source, converters, and an induction motor‐pump group; it has a hybrid and complex character and requires a good modelling of the energetic point of view before passing the phase of design of control laws. So we use the graphical approach of modelling called dedicated graph for this type of system, and this tool showed very interesting results in the level of modelling, dimensioning, monitoring, and diagnosing. The numerical closed‐loop simulation of the complete model in an appropriate environment allows us to generate an optimization control in which the appropriate frequency depends on meteorological conditions. The simulations are made from the climatic conditions measured in a real system using a microcontroller ARDUINO board. These measurements are used to simulate the adopted control and to judge on the feasibility of our architecture adopted.

通过频率优化对离网式混合泵系统的键合图建模和控制增强

气候的依赖性要求复杂的建模和其他优化方法来控制混合系统。而且,最近,对于硬件和软件的技术进步,研究人员可能会通过使用已启用的平台来越来越多地优化问题。本文旨在讨论这个问题。我们的混合泵设备包括光伏发电机,风源,变流器和感应电动机泵组;它具有混合性和复杂性,在通过控制定律设计阶段之前,需要对能量的观点进行良好的建模。因此,对于这种类型的系统,我们使用称为专用图的图形化建模方法,该工具在建模,标注,监视和诊断方面显示出非常有趣的结果。在适当的环境中对完整模型进行数值闭环仿真,使我们能够生成优化控制,其中适当的频率取决于气象条件。这些模拟是使用微控制器ARDUINO板根据实际系统中测得的气候条件进行的。这些度量用于模拟采用的控制并判断采用我们的体系结构的可行性。
