超级电容吸收再生电能和抵御供电断续的试验研究

Research on Using Super Capacitor to Store Renewable Electrical Energy and Compensate Power Intermitting

在某些恶劣电网环境下运行的变频传动系统,可以利用超级电容(SC)优异的充放电性能,既吸收利用传动系统产生的大量再生电能,又维持其在电压暂降、供电中断时平稳运行,一举两得。笔者给出了简单实用的控制策略,经仿真和试用证明是行之有效的。

You can make use of super-capacitor （SC） excellent charge and discharge performance to absorb and store large quantities of renewable electrical energy from the inverter ASD（Adjustable Speed Drive）,When such inverter run in poor power network environment, the SC releases the renewable energy to compensate power voltage sag, to stable power supply interruption. The author gives simple and practical control strategy, through simulation and testing proved to be effective.
