【摘要】 超级电容器作为一种新型电力储能技术,由于其动态响应速度快,储、释能效率高,产品规格化无需定制,便于扩容等特点,被认为是一种非常有前途的电能存储器件。超级电容器直流储能单元是超级电容器储能系统中最为关键部位,其可靠工作对提高超级电容器储能系统的效率和能量利用率,增强储能系统的可靠性具有重要的意义。本文立足于超级电容器直流储能单元的研究与应用设计,建立了超级电容器与蓄电池直接并联储能的等效模型;针对脉动负载,分析了储能系统的性能改善及其影响因素。对超级电容器应用于直流屏,通过前馈控制加反馈控制来调节系统运行,并用MATLAB进行仿真实验,验证了设计的可靠性,这对于超级电容器直流储能单元的实际应用具有一定的理论意义和实用价值。更多还原

【Abstract】 As a new kind of energy storage component, supercapacitors have fast response, high charge-discharge effciency, and there are types of commodities on sale which speedup assemble and facilitate to enlarge energy storage capacity, therefore the supercapacitor is considered the most promising energy storage device. Supercapacitor dc energy storage system is the key device of the supercapacitor energy storage system. It plays an important role on improving efficiency and reliability of supercapacitor energy storage system. In conclusion, based on some important aspects of Supercapacitor energy storage unit application and design, the equivalent model of directly paralleled supercapacitor/Battery hybrid was set up and the performance and its influence factors were analyzed quantificationally with pulsant load as an example. As supercapacitor use in dc power supply, design feedforward plus feedback to regulate the system operation, MATLAB simulation results presented to show the feasibility, which have theory and practical meanings to provide optional scheme to the project applications.更多还原
