Biodiesel is a. excellent option for reducing dependence on fossil fuels with environmenta. a.va.ta.es by reducing ha.a.dous emissions. The enzyma.ic tra.sesterifica.ion ha. a.tra.ted the a.tention of resea.chers in the la.t deca.e a.d the a.va.ta.es of enzyma.ic ca.a.ysis show tha. the production of biodiesel by this route ha. good potentia., ma.nly beca.se it is friendly environment. For biodiesel, production process by enzyme ca.a.ysis is chosen the response surfa.e methodology. It is a. experimenta. stra.egy to find the best opera.ing conditions oftra.sesterifica.ion rea.tion to improve the biodiesel qua.ity. The Process ha. three va.ia.les： tempera.ure, mola. ra.io oil-a.cohol a.d ca.a.yst qua.tity. The process wa. monitored by GC-FID （ga. chroma.ogra.hy with fla.e ioniza.ion detector）. The yield of the tra.sesterifica.ion rea.tion by enzyma.ic ca.a.ysis decrea.es with increa.ing tempera.ure, a.d ma. be due to ina.tiva.ion of the enzyme by dena.ura.ion a. tempera.ures a.ove 50 ℃.

本文对孤立直流微电网动态特性进行了分析,并提出了改善策略。在孤网条件下,电压主要靠系统中基于储能的DC/DC变换器进行控制,因此多DC/DC变换器动态特性即可反应系统全局的动态特性。本文中各DC/DC变换器采用Ⅰ-Ⅴ下垂控制,并以负载的变化量为输入,变换器输出电流、占空比及母线电压为状态变量对多DC/DC变换器进行了大信号模型的建立。基于上述模型,本文对输出电流动态特性的影响因素进行了根轨迹分析,最后提出自适应P控制策略以提高直流微电网中的动态特性。最后通过仿真对提出的模型及控制策略进行了验证。

In this work is described the synthesis of a.multifunctiona. thiola.ed squa.ene. Thiol-ene coupling rea.tions were employed to functiona.ize the six double bonds of squa.ene, using thiola.etic a.id. Hydrolysis of the resulting thioa.eta.es, rendered the corresponding hexa.hiola.ed squa.ene SQ6SH. This compound wa. further photopolymerized sepa.a.ely with tria.lyl cya.ura.e, penta.rythritol tria.ryla.e a.d diethyleneglycol divinyl ether. Rea. Time FTIR kinetics revea.ed tha. homopolymeriza.ion of the ene monomers took pla.e in a.dition to the thiol-ene photopolymeriza.ion. Flexible films were obta.ned when SQ6SH wa. photopolymerized in bulk with the a.ove mentioned unsa.ura.ed monomers.

根据孤岛情况下混合微电网的运行特点建立了接口换流器的数学模型并设计了基于滑模控制(Slidingmode control,SMC)的接口换流器控制系统。该控制系统将SMC和比例谐振控制(proportion resona.t,PR)相结合,同时利用了SMC的快速响应性、强鲁棒性以及PR控制能够抑制谐波的优点。仿真和实验结果表明,该控制系统可以保证接口换流器在不确定和非线性条件下的鲁棒性和快速响应,为微电网提供电压、频率支撑,保证其孤岛后的稳定运行。
