基于直流电压前馈的构网型光伏稳定性优化控制策略

Gaoya dianqi
构网型光伏表现出电压源特性，对电网具有较强的适应性。文中以基于直流电压同步的构网型光伏为研究对象，建立了构网型光伏的阻抗小信号模型，通过阻抗分析研究了构网型光伏的稳定性。在稳定性分析基础上提出了基于直流电压前馈的构网型光伏稳定性优化控制策略，对比分析了改进的构网型光伏的稳定性。最后通过控制器硬件在环实验验证了文中所提控制策略的有效性和理论分析的正确性。

超纯水系统国产除硼树脂的筛选及应用研究

Gongye shui chuli
硼是超纯水水质的关键指标之一，可通过除硼树脂去除，但市场上除硼树脂主要被国外企业垄断，国产树脂应用少，运行参数和稳定性不明确，市场推广难度大。通过除硼树脂静态吸附试验和连续流中试，开展对典型国产除硼树脂的性能评价和项目应用研究。根据吸附容量、有机碳溶出、再生稳定性、长期运行稳定性、采购成本及货源稳定性等多元评价指标，筛选出性能优异的国产除硼树脂，硼吸附量可达5.1 g/L，TOC溶出量低至3.01 μg/L，经过10次再生后除硼吸附量为新树脂的97.84%，在中试线实现了连续9个月高标准除硼和稳定运行 ...
