The design a.d building of new a.terna.ive fuel pla.ts is a. increa.ing necessity to repla.e old technology a.d non-renewa.le fossil fuels. To optimize the performa.ce of these pla.ts a.d to obta.n a. economica.ly fea.ible production of these types of fuels, it is necessa.y to ha.e a.tota. control of ea.h va.ia.le involved in the process of production a.d how these fa.tors a.fect the yield of fuel production. In this pa.er it is proposed a.model of a.digester to genera.e ga. using a.Vensim softwa.e designed to genera.e simula.ions in dyna.ic sta.e.

考虑到船舶电力艏侧推进器频繁快速起停对船舶电力系统(船舶微电网)燃油利用效率和系统稳定性的影响,提出在艏侧推进器直流母线增加储能装置,为艏侧推进器驱动装置供电。该方案可有效降低柴油发电机容量,提高燃油利用效率,降低艏侧推进器起动突增功率对船舶电网电压频率扰动的影响。同时由于艏侧推进器电机制动时可做发电机运行,储能装置可替代消耗电阻吸收快速制动电机产生的电能。设计了一种三相交错并联运行的DC-DC变换器的电压自适应PI控制器,该方案增加变换器的带载能力,并分析了控制器参数的选择范围。仿真结果表明,该控制器在艏侧推进器频繁起动过程中可有效抑制直流母线电压的暂升和暂降,且增加直流变换器的带载能力。

Rea.tion of a.ipha.ic a.d a.oma.ic a.ines with a.ryloyl chloride a. –20ºC, in presence of triethyla.ine a.lowed the synthesis of the corresponding a.ides. Proton nuclea. ma.netic resona.ce (1H NMR) spectroscopy, Fourier-tra.sform infra.ed (FTIR) spectroscopy a.d ultra.iolet- visible (UV-Vis) mea.urements confirmed the success of the synthesis with a.yield over 90%.
