摘要
提出了一种双向DC/DC变换器双闭环控制策略以及主电路参数设计方法,在此基础上,通过仿真实现了一种基于DC/DC变换器的直流组网系统稳定性分析方法,仿真测试验证了基于该策略的正确性,以及直流组网系统在负载频繁突变以及故障恢复下的稳定性,具有动静态响应小,电能品质优良的特点,同时对基于该双向变换器的蓄电池充放电模式切换进行仿真验证,结果同样表明了本文设计方法的有效性,对直流组网系统设计具有一定的参考意义和实用价值。
A double closed-loop control strategy of bi-directional DC/DC converter and the design method of main circuit parameters are proposed.On this basis,a stability analysis method of DC/DC converter based on DC/DC converter is realized through simulation.The correctness of the strategy based on this strategy and the stability of the DC networking system under frequent load mutations and fault recovery are verified.It has the characteristics of low dynamic and static response and excellent power quality.At the same time,the battery charging and discharging mode based on the bi-directional converter is verified.The results also show the effectiveness of the design method,which has certain reference significance and practical value for the design of DC network system.
