摘要
为了研究行波电帘清除光伏组件表面微尘的机理,提出一种基于COMSOL多物理场仿真软件的电帘除尘建模方法,建立三相行波电帘与带电微尘颗粒相耦合的动力学模型。研究不同电极、电源参数和环境因素下微尘颗粒的运动,首次分析电极形状对电场分布和场强的影响。结果表明,三相行波电帘能有效实现尘埃的定向输运,带正电微尘颗粒会以跳跃、帘状或冲浪模式沿行波传播方向移除电帘,但微尘颗粒的运动模式及除尘效率受多种因素影响。
In order to investigate the mechanism of dust particles on the surface of a solar cell panel removed by the traveling-wave electric curtain,a numerical modelling approach for the dust removal using the electric curtain technology was presented based on the COMSOL Multiphysics simulation software.The dynamics model for the coupling between the three-phase traveling-wave electric curtain and the charged dust particles was established.The motion of dust particles in various cases of electrode,power,and environment parameters was studied.The influences of electrode shapes on distribution and intensity of the electric fields were analyzed for the first time.The results of numerical simulations indicate that the dust particles can be transported directionally by the three-phase travelingwave electric curtain,and the dust particles with positive charge are removed along the direction of traveling-wave propagation and through hopping,curtain,or surfing modes;however,the motion modes of dust particles and the efficiency of dust removal are dependent on numerous factors.
