In order to explore the dust deposition characteristics on the surface of photovoltaic(PV) modules. For the dust accumulation problem of ground-mounted photovoltaic, the deposition characteristics of dust particles with different particle sizes were investigated from two factors, namely, tilt angle and wind speed, by using CFD numerical simulation method. The results show that as the tilt angle of the PV module increases, the deposition rate of dust on the surface of the PV module gradually decreases, in addition, it is found that when the PV module is facing the wind, the rate of dust deposition increases with the increase of wind speed, and the maximum particle size of dust deposition will become larger with the increase of wind speed. At the same time, with the increase of particle size, the deposition of dust on the surface of the PV module is the first to increase and then decrease. The study is of great significance in solving the problem of dust accumulation in photovoltaic power plants.

为了探究光伏组件表面灰尘沉积特性,针对地面光伏的积灰问题,利用计算流体动力学(computational fluid dynamics,CFD)数值模拟方法,从倾斜角度和风速两个因素研究了不同粒径的灰尘颗粒的沉积特性。结果表明:随着光伏组件倾斜角度的增大,光伏组件表面灰尘的沉积率逐渐减小,除此之外,发现当光伏组件迎风时,灰尘沉积率随着风速的增加而增加,最大灰尘沉积粒径均会随着风速的增加而变大。同时随着粒径的增大,光伏组件表面灰尘的沉积率先增大后减小。研究结果对探究光伏积灰特性及解决光伏电站的积灰问题有着重要的意义。

In order to explore the dust deposition characteristics on the surface of photovoltaic(PV) modules. For the dust accumulation problem of ground-mounted photovoltaic, the deposition characteristics of dust particles with different particle sizes were investigated from two factors, namely, tilt angle and wind speed, by using CFD numerical simulation method. The results show that as the tilt angle of the PV module increases, the deposition rate of dust on the surface of the PV module gradually decreases, in addition, it is found that when the PV module is facing the wind, the rate of dust deposition increases with the increase of wind speed, and the maximum particle size of dust deposition will become larger with the increase of wind speed. At the same time, with the increase of particle size, the deposition of dust on the surface of the PV module is the first to increase and then decrease. The study is of great significance in solving the problem of dust accumulation in photovoltaic power plants.

光伏电站在全世界广泛分布,为了获得充足的太阳能和不影响人类的正常活动,光伏电站大多都建立在戈壁、沙漠等开阔却干旱的地方[1]。虽然光伏电站在这些地方能充分接受太阳光并把它转化成电能以供人类使用,但是它们要经受强烈的风沙和鸟粪等杂质的污染[2]。Tian等[3]发现,粉尘已成为戈壁、沙漠、高原等地区光伏发电的一个严重问题。长此以往,这种污染会造成光伏阵列的老化、腐蚀[4]。更重要的是,在这些地区,大量的灰尘沉积在光伏板表面会严重影响光伏电池的发电效率。当太阳光到达光伏板时,它会首先通过玻璃层,玻璃层的传输能力对光电转换效率影响很大[5-7]
因此,研究光伏玻璃表面的灰沉沉积机理对提高光伏发电效率有着重要的作用,对光伏发电行业的发展有着巨大的促进作。很多学者研究怎样减少光伏板灰尘沉积。光伏组件上的粉尘沉积主要受环境因素、光伏组件因素和粉尘因素的影响。有研究发现像降雨、风、湿度等环境因素会显著影响光伏板表面的灰尘沉积[8-11]。除此之外,光伏阵列放置的位置、倾角以及高度对灰尘沉积率也有着显著的影响。将光伏板安装在高海拔的地方能够减少光伏板表面的灰尘沉积,并且会延长光伏组件的使用寿命[12]。除了环境和光伏阵列自身的因素,灰尘颗粒本身的尺寸、密度、粉尘材料对灰尘沉积率都有影响[13-16]。有学者调查了欧洲污染最严重的城市之一克拉科夫在非采暖季节不同气象条件下光伏组件覆盖玻璃上的灰尘沉积过程。发现光伏组件表面的灰尘沉积率受到该城市的降水和湿度影响强烈[17]。Lu等[18]采用离散粒子模预测了光伏电池板上的灰尘沉积率。研究了太阳能光伏系统周围的湍流风流场、不同粉尘直径和风速下光伏电池板的粉尘沉积率以及对不同类型光伏组件输出效率的影响。发现当粉尘直径增大时,光伏电池板上的粉尘沉积速率先增大后减小。以往对光伏系统流场的研究大多集中在二维仿真模拟,这种方法简单并且成本低,但是不能全面地贴近现实情况。三维仿真模拟能相对真实地体现光伏系统周围流场地状态。
现通过使用计算流体动力学(computational fluid dynamics,CFD)方法研究迎风状态下光伏组件表面的灰尘沉积特性,从倾斜角度和风速两个因素研究不同粒径的灰尘颗粒的沉积特性。
研究的计算域如图1所示。计算域的长度为35.31 m,高度为9.9 m。在计算域内部放置一块光伏组件,光伏组件为单面单晶硅组件,其功率为500 W,根据该光伏组件1∶1建立仿真模型,光伏板的长为2.48 m,宽为2.48 m,厚为5 cm,支撑高度为1.5 m。光伏板的倾斜角度为θ,光伏支架是一个长、宽均为0.1 m的长方体。光伏板到入口处的距离是5He,到出口的距离是15He,He为光伏组件高度。灰尘颗粒从入口处释放,初始速度采用用户自定义函数(user-defined functions,UDF)。
采用结构性网格,主要原因是流动复杂程度不高,且方便调节网格参数,如网格间距、增长率等。图2展示了研究域的结构化网格,网格总数达40万。在光伏板近壁区域考虑了边界层的作用,设计了渐变网格。第一个网格无量纲壁面距离y+为1.4×10-4 m,网格的生长因子为1.2。由于光伏支架可以视为一个截面圆柱体,因此对其进行o-block切块划分。不同倾斜角度、风速的网格数相同,均为40万,但y+墙距会根据风速进行对应修改。
模拟光伏系统表面吹灰过程中,应用Navier-Stokes方程对进口来风的风速、质量以及动能进行了解和研究。一般来说,随着风流吹来的灰尘颗粒是离散的。因此需要通过求解一些颗粒动力学方程不同的灰尘颗粒的运动轨迹进行跟踪。采用方程离散颗粒(discrete phase,DPM)模型,考虑了热泳力、萨夫曼升力以及质量力等影响粒子运动轨迹的力以达到预测粒子运动和扩散的目的。除此之外,与粒子的湍流分散过程有关的模型是通过离散随机游走(discrete random walk,DRW)模型来建立的。光伏系统周围的湍流风流场和灰尘沉积规律分别通过剪切应力传递(shear stress transport,SST)k-ω湍流模型和DPM进行求解和预测。
在分析灰尘颗粒沉积之前,对光伏系统周围的空气流场的模拟尤为重要。因为空气流场在很大程度上影响着灰尘颗粒的运动轨迹。在CFD模拟方面,直接数值模拟(direct numerical simulation,DNS)或大涡模拟(large eddy simulation,LES)因为其准确性被广泛应用。但是它们具有计算和时间成本高的缺点。所以,为了减少计算成本,采用雷诺平均纳维-斯托克斯(Reynolds-averaged Navier-Stokes,RANS)模型预测气流场。RANS方法在预测建筑周围流场的颗粒物沉积情况时也比较准确[19]。Karava等[20]比较了不同湍流模型对建筑物周围风流的数值结果,发现与其他模型相比,SST k-ω湍流模型预测的准确率最好。这是因为SST k-ω湍流模型结合了壁面附近的k-ω模型和自由剪切层中的k-ω模型。故采用SST k-ω湍流模型预测风流场。孤立太阳能光伏系统周围湍流空气流场质量守恒和动量守可以通式(1)和式(2)来描述,SST k-ω 湍流模型的运输方程在式(3)和式(4)中得到解释[21]
$\frac{\partial \stackrel{-}{{u}_{i}}}{\partial {x}_{i}}=0$
$\begin{aligned} \frac{\partial \bar{u}_{i}}{\partial t}=0+\bar{u}_{j} \frac{\partial \bar{u}_{i}}{\partial x_{j}}=-\frac{1}{\rho} \frac{\partial \bar{p}}{\partial x_{i}}+\frac{1}{\rho} \frac{\partial}{\partial x_{j}}\left(\mu \frac{\partial \bar{u}_{i}}{\partial x_{j}}-\rho \bar{u}_{i}^{\prime} \bar{u}_{j}^{\prime}\right) \end{aligned}$
$\frac{\partial}{\partial t}(\rho k)+\frac{\partial}{\partial x_{i}}\left(\rho k u_{i}\right)=\frac{\partial}{\partial x_{j}}\left(\Gamma_{k} \frac{\partial k}{\partial x_{j}}\right)+\tilde{G}_{k}-Y_{k}+S_{k}$
$\begin{array}{c} \frac{\partial}{\partial t}(\rho \omega)+\frac{\partial}{\partial x_{i}}\left(\rho \omega u_{i}\right)=\frac{\partial}{\partial x_{j}}\left(\Gamma_{\omega} \frac{\partial \omega}{\partial x_{j}}\right)+ \\ G_{\omega}-Y_{\omega}+D_{\omega}+S_{\omega} \end{array}$
式中:ρ为空气密度;${\overline{u}}_{i}$$\overline{p}$分别为时间平均速度和压力;${\stackrel{~}{G}}_{k}$Γk分别为湍流动能的产生项和扩散项;GωΓω分别为比耗散率的产生项和扩散项;YkYω分别为湍流动能和比耗散率的耗散项;SkSω分别为用户定义的源术语,将SkSω均设为零。
利用DPM模型来对光伏板表面的灰尘颗粒轨迹进行预测。DPM模型可以很好地反映光伏板表平面地灰尘沉积率,其控制方程为
$\begin{aligned} \frac{\mathrm{d} u_{p}}{\mathrm{~d} t}= & \frac{1}{\tau} \frac{C_{\mathrm{D}} R e_{\mathrm{p}}}{24}\left(u_{\mathrm{g}}-u_{\mathrm{p}}\right)+\frac{g\left(\rho_{\mathrm{p}}-\rho_{\mathrm{g}}\right)}{\rho_{\mathrm{p}}}+ \\ & \zeta \sqrt{\frac{\pi S_{0}}{\Delta t}}+\frac{2 \rho K_{\mathrm{c}} v^{0.5}}{\rho_{\mathrm{p}} d_{\mathrm{p}}\left(S_{\mathrm{lk}} S_{\mathrm{kl}}\right)} S_{i j}\left(u-u_{\mathrm{p}}\right) \end{aligned}$
式(5)中:CD为阻力系数;Rep为粒子雷诺数,表示每单位质量的惯性力与黏性力的比值;ugup分别为流场中流体和灰尘颗粒的运动速度;g为重力加速度;ρgρp分别为流体和颗粒的密度;ζ为正态分布的随机数;S0为随机力的强度参数;Δt 为时间步长;Kc为与颗粒碰撞或流体作用相关的系数;v为运动黏度;SklSlk为无量纲参数;${{S}_{i}}_{j}$为变形张量;u为局部速度;τ为弛豫时间,可通过方程式(6)计算,即
$\tau =\frac{S{d}_{\mathrm{p}}^{2}{C}_{\mathrm{C}}}{18v}$
式(6)中:S为灰尘颗粒和流体的密度比;CC为Cunningham滑移修正因子。
CD的表达式为
${C}_{\mathrm{D}}=\left\{\begin{array}{ll}\frac{24}{R{e}_{\mathrm{p}}},& R{e}_{\mathrm{p}}<1\\ \frac{24}{R{e}_{\mathrm{p}}}(1+0.15R{e}_{\mathrm{p}}^{0.687}),& 1<R{e}_{\mathrm{p}}<400\end{array}\right.$
为了正确预测灰尘颗粒的运动轨迹,考虑了不同的影响颗粒作用的力,例如曳力、重力、浮力、布朗力和萨夫曼升力。这些力对光伏板表面灰尘沉积行为有着重要的影响。由于研究中的光伏系统布置在沙漠、戈壁等干旱地区,所以忽略了湿度对气流和颗粒间碰撞的影响。
计算域入口条件参考Tominaga等[22]获得的实验测量。入口风流的主要参数是风速和湍流动能(turbulent kinetic energy,TKE)。采用UDF,初始速度设为2.6 m/s。灰尘颗粒在入口处以空气流速进入计算域。注入的高度控制在光伏系统的3倍高度以内。在忽略灰尘颗粒的反弹和再悬浮效果后,假设灰尘颗粒一旦到达光伏板表面就会沉积。因此在Ansys Fluent中对光伏板表面设置“Trap”条件。假设灰尘颗粒一旦到达出口就会离开计算域。因此,在计算域出口处设置“Escape”条件。使用的灰尘颗粒为碳酸钙,定义为球形,密度为 2 800 kg/m3
网格无关性研究可以很好反映出网格的分辨率。分别取用20万、40万、60万、80万的网格数。通过数值验证测得这几种不同网格数的模型在Z=1.5 m处的风速分布,如图3所示。发现几种网格的速度分布图差别不大,40万以上的网格的速度分布基本上没有差别。相比之下,20万的速度分布则跟其他有一些细微的差别,尤其是在Y轴上的距离在13~15 m。因此,使用的网格为40万以防止出现任何非持久性结果。
为了验证模拟的准确性,将模拟的入口处的风速和湍流动能与Tominaga等[22]在风洞实验中获得的数据进行对比,发现有很好的拟合效果,如图4所示。
光伏系统在实际应用的时候,倾斜角度的改变对其表面灰尘沉积有着很大的影响,将倾斜角度改变,采取30°、45°以及60°等不同的角度来探究其对灰尘沉积的影响。并且研究了在这种变化下,不同的颗粒粒径的沉积特性有何不同。图5Y-Z平面上不同倾斜角度下的光伏组件周围流场风速流线图。图6是不同的倾斜角度下,不同颗粒粒径的灰尘沉积率。
观察图5可以发现,光伏支架的湍流涡旋出现在光伏组件背面,涡旋回流的灰尘不与光伏组件表面直接发生碰撞。光伏组件涡旋的产生与光伏面板、光伏支架和地面之间的封闭空间体积密切相关。从图6发现,灰尘沉积率随着光伏组件倾斜角度的增加而减小。当倾斜角度为30°时,100 μm的灰尘沉积率最高,达7.82%。其次是45°时为7.80%,60°时为6.63%。观察30°和45°的速度场[图5(a)图5(b)],可以发现30°和45°的流场非常相似,因此它们的沉积特性差距不大。一方面,倾斜角度的大小决定了光伏组件表面与迎风吹来的灰尘的碰撞接触面积,当倾斜角逐渐增大时,迎风面积越大,灰尘的碰撞角更接近垂直,因此更不容易沉积在光伏组件表面;另一方面,当光伏组件倾斜角度越大,灰尘颗粒受重力的影响更大,灰尘更不易沉积在光伏组件上。这一结论与Khodakaram-Tafti等[23]关于不同倾角光伏系统积灰后性能影响的实验研究结果相一致。研究表明,随着光伏组件倾斜角度的增大,积灰量逐渐减少,同时光伏组件日均发电量的减少幅度也随之降低。
为了研究入口风速对光伏组件灰尘沉积特性的影响,选择45°倾斜的光伏组件进行模拟。研究了入口风速分别为1.3、2.6、3.9和5.2 m/s,灰尘密度为2 800 kg/m3时CaCO3的灰尘沉积特性,灰尘入射初始速度为光伏组件高度(He)处的风速。
图7为不同风速下光伏组件的灰尘沉积特征。当光伏组件迎风时,随着风速的逐渐增大,灰尘沉积率随粒径的增大先增大后减小。总灰尘沉积率、灰尘沉积范围、最大灰尘沉积粒径随风速的增大而增大。当风速达到5.2m/s时,灰尘沉积率最大达到11.47%。此外,灰尘的最大粒径也有所增大,在1.3 m/s时最大粒径为50 μm,在2.6 m/s时最大粒径为100 μm,在3.9 m/s时最大粒径约为125 μm,在5.2 m/s时最大粒径为150 μm。这一发现与Goossens等[24]的研究结果相吻合,他们探讨了在不同风速条件下光伏组件积灰对电池性能的影响。研究揭示,风速对电池性能的下降具有显著影响:风速越大,积灰量越多,相比之下,大风情况下电池性能的下降幅度要大于小风时的情况。
图8展示了不同风速下灰尘颗粒运动轨迹图,可以发现灰尘在不受光伏组件遮挡时在流场中做抛物线运动,受光伏组件结构影响,灰尘运动轨迹发生变化,且风速越大,灰尘运动距离越远,灰尘运动范围越广。这是因为风速为流场中运动的灰尘提供一定的动能,灰尘在流场中做抛物运动,在横向上由入口风速提供动力,在垂直方向上由重力提供动力。灰尘携带的动能随着风速的增大而增大,原本沉积在光伏组件前方的灰尘因为风速的变大移动得更远,灰尘沉积速率增大。光伏组件后方产生的涡团会夹带部分灰尘回流,但大部分灰尘与光伏组件背面发生碰撞,少量灰尘会与光伏组件正面发生碰撞沉积,因此涡旋在不同风速下对光伏组件表面灰尘沉积特性的影响不显著,可以忽略。因此,灰尘沉积率随着风速的增加而增加。
图7所示,在相同风速下,随着粒径的增大,光伏组件表面灰尘的沉积率先增大后减小。首先,随着颗粒粒径增大,颗粒的惯性效应增强,这使得颗粒在空气流动中更容易保持稳定的沉积状态。较大的颗粒由于惯性较大,对空气流的惯性阻力也随之增加,因此它们更容易被流体带动并沉积在光伏组件表面上。这是沉积率先增大的主要原因之一,因为在一定范围内,随着颗粒尺寸增大,它们的沉积速度会随之增加,从而使沉积率随粒径增大而增大。然而,随着颗粒粒径继续增大,其惯性效应并非线性增加。较大的颗粒可能达到一个临界点,超过这个点后,颗粒的惯性阻力增加到一定程度会使其难以随流体流动而保持稳定沉积在表面上。此时,流体的运动特性也会对颗粒的悬浮和沉积产生影响,可能会导致颗粒重新悬浮或者在表面上短暂停留而未能长期稳定沉积。因此,随着颗粒粒径进一步增大,沉积率会因颗粒的惯性效应增强到一定程度而开始下降,形成沉积率先增大后减小的趋势。
以孤立地面光伏系统为研究对象,研究了不同的倾斜角度下光伏组件周围流畅的不同,以及不同粒径的灰尘颗粒的沉积规律。除此之外,将入口处的风速改变,研究了分别在1.3、2.6、3.9和5.2 m/s时,光伏组件表面的灰尘颗粒的沉积特性。发现倾斜角度和风速对灰尘沉积特性有着显著的影响,具体结论如下。
(1)研究三维模型不同倾斜角度对光伏组件表面灰尘沉积特性的影响,发现灰尘沉积率随着光伏组件倾斜角度的增加而减小。
(2)研究不同风速对灰尘沉积特性的影响,发现风速并不会影响光伏系统流场的速度、湍流动能以及迹线的分布情况,仅仅改变离散项灰尘颗粒的运动方式。当光伏组件迎风时,最大灰尘沉积粒径均会随着风速的增加而变大。
(3)研究不同风速对灰尘沉积特性的影响,发现随着粒径的增大,光伏组件表面灰尘的沉积率先增大后减小。
以上研究系统分析了光伏组件表面灰尘沉积特性,通过模拟不同风向和风速下灰尘在光伏组件表面沉积的模式,可以帮助制定更有效的清洁策略。例如,了解哪些区域最容易积尘,可以在清洁时重点关注这些区域,对光伏系统除灰有着重要的作用。然而光伏阵列的研究更加接近真实的情况,因此在未来的研究中可以考虑研究不同影响因素下后方来风对光伏阵列的影响。
