摘要
组态优化技术是提高光伏阵列(Photovoltaic Array,简称PVA)输出功率的重要方法。在实验分析基础上,得出了局部阴影下TCT组态光伏阵列的输出特性。将一种简单、控制效果较好的组态优化控制算法从太阳能电池元推广到光伏组件,并基于DSP设计了光伏阵列动态组态优化系统的平台。该系统不仅简化了硬件平台,同时对组态优化控制算法进行了改进,使系统控制变得简单可靠,实验结果验证了该方案的正确性。
The technique of optimize configuration of photovohaic array （PVA） is an important method to improve the maximum power.First of all, output characteristic of PV array is obtained through experiment in the condition of partial shadow total cross total（TCT）.Then,a presented control method with simple algorithm and good control effect is researched and its application is extended from PV cells to modules.Finally a platform based on DSP is designed and buih.The hardware platform is simplified and the control algorithm for optimize configuration is improved.The system becomes simple and reliable.The correctness of this method is verified through experimental results.
