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。

Effects of CeO2 on Bi2O3-rich Lead-free Sealing Glass Ceramics [PDF]
, 2012 传统上，国内外电子与电器设备上的电热管常用的封接材料是含Pb微晶玻璃；但是，由于含Pb玻璃有毒，美日欧及我国等先后采取了相关措施，对封接材料的含Pb量作了严格法律的限制。因此，研制无Pb封接微晶玻璃具有十分重要的意义。本研究作为制备结构材料，对于Bi2O3原料的纯度要求不高，可提取自某些稀土尾矿，CeO2如能应用于封接用无Pb封接微晶玻璃，则对尾矿处理、稀土综合利用和轻稀土大量堆积等问题的解决有积极的作用，且加入少量CeO2可以有效提高封接玻璃与添加铈的合金的结合能力。 本研究在全面深入的调研的基础上 ...
