为研究局部阴影效应对光伏发电系统的影响，首先建立了光伏阵列工程数学模型，分析局部阴影条件下光伏阵列的输出特性。为了便于工程分析，该文利用PVSYST软件分析比较单晶硅、多晶硅和薄膜电池等3种不同材料光伏电池在局部阴影条件卜的输出功率，为工程应用提供了良好的指导作用。最后提出了几种提高光伏阵列抗局部阴影能力的措施厂
(To investigate the effect of local shading effects on photovoltaic systems, photovoltaic array project was first established mathematical model to analyze the output characteristics under conditions of partial shading of the PV array. In order to facilitate engineering analysis, this paper use PVSYST software analysis and comparison monocrystalline, polycrystalline and thin film batteries, photovoltaic cells of three different materials in partial shade conditions Bu output power for engineering applications provide a good guide. Finally, several photovoltaic arrays to improve the ability to measure resistance to partial shade plant)

SVPWM_VSI
说明： SVPWM是近年发展的一种比较新颖的控制方法，是由三相功率逆变器的六个功率开关元件组成的特定开关模式产生的脉宽调制波，能够使输出电流波形尽可能接近于理想的正弦波形。空间电压矢量PWM与传统的正弦PWM不同，它是从三相输出电压的整体效果出发，着眼于如何使电机获得理想圆形磁链轨迹。SVPWM技术与SPWM相比较，绕组电流波形的谐波成分小，使得电机转矩脉动降低，旋转磁场更逼近圆形，而且使直流母线电压的利用率有了很大提高，且更易于实现数字化。(SVPWM is a novel control method developed in recent years. It is a pulse width modulation wave generated by a specific switching mode consisting of six power switching elements of three-phase power inverters, which can make the output current waveform as close as possible to the ideal sinusoidal waveform. Space voltage vector PWM is different from traditional sinusoidal PWM. It is based on the overall effect of three-phase output voltage, focusing on how to obtain the ideal circular flux trajectory of the motor. Compared with SPWM, the harmonic component of winding current waveform is smaller, which reduces the torque ripple of motor, makes the rotating magnetic field more close to the circle, and improves the utilization ratio of DC bus voltage greatly, and makes it easier to realize digitization.)
