摘要
对基于锂电池的家用5 kW单相储能系统进行了设计,建立了基于双向半桥DC/DC变换器和双向DC/AC PWM变流器的功率转换系统,设计了基于虚拟移相技术的有功无功解耦控制算法,实现了储能系统的四象限运行。仿真结果表明,该控制系统除可对锂电池充放电之外,还可以提供无功补偿,同时电流谐波较小。
A 5 kW Li-ion battery based single-phase energy storage system is presented. A power con- version system is designed, which consists of bi-directional half bridge DC/DC converter and DC/AC PWM converter. A virtual phase-shifting method based decoupling algorithm is analyzed to achieve the four-quadrant operation. The simulation results show that the method can not only charge and discharge Li-ion battery, but also compensate the reactive Dower of ~rid and reduce the distortion of current.
