废弃植物油再生利用的研究

文章介绍了用废弃植物油经酯交换反应制成柴油替代燃料的方法和工艺流程，并讨论了提高反应产率的最佳工艺参数。研究表明：在反应温度为70℃，当油醇的物质的量比为1：6，以NaOH为催化剂且浓度为1．0％，反应时间为20～30min时，酯交换反应制取脂肪酸甲酯(生物柴油)的产率为92％。用废弃植物油转化制成的脂肪酸甲酯，是石化柴油很好的替代能源。     

Development of a Hybrid Simulator for Power System Analysis for a High Penetration of Distributed Generations

Chubu Electric Power Co., Ltd.’s hybrid power system simulator consists of analog models and hybrid models. The power system facilities are downsized as an analog model, while the synchronous generators and the loads are modeled as an actual current source model through the amplifier and the digital model. In recent years, there is a growing interest in analyzing power system dynamic phenomena caused by a high penetration of distributed generations. Therefore, the multifunctional generator model that can simulate distributed generation has been developed.
