摘　　要：为了适应日益苛刻及复杂场景下的保供电需求,研发了多模式在线保供电移动储能装置,能够根据实际情况提供串联、并联及双回路3种保供电模式。针对3种保供电方案介绍了接入方式,提出了储能系统的供电方法及控制程序。深入分析了储能装置的控制策略及无缝切换技术,提出了重复控制与PID控制相结合的储能变流器复合控制方法,该方法能够有效提升非线性负荷接入时供电系统的电能质量。分别搭建实验平台,针对阻性、阻感和阻容3种性质的负荷进行了多模式保供电实验,实验证明该装置串联模式保供电性能最好、并联模式实现了无缝切换、双回路模式实现了多回路供电。总体上3种模式各有优缺点,该装置可以根据不同场景提供多模式的保供电方案,能够较好地实现在线保供电等目标。In order to meet the increasingly demands and complex scenarios under the power supply needs,we developed a multi-mode online power-saving mobile energy storage device.The divice can provide series,parallel,and dual-loop power supply modes according to the actual situation.Aiming at the three kinds of power supply modes,we introduced the access method,and put forward the power supply method and control program of the energy storage system.The control strategy of energy storage device and the seamless switching technology were analyzed.The combined control method of energy storage converter with repetitive control and PID control was proposed,which could effectively improve the power quality of the power supply system when nonlinear load was connected.The experimental platform was set up separately,and the multi-mode protection power supply experiments were carried out for the load of the three types of resistance,resistance-inductance,and resistance-capacity.The experiments show that the series mode of the device has the best power supply performances,the parallel mode realizes seamless switching,and the double loop mode realizes the multi-loop power supply.In general,the three models have their own advantages and disadvantages.The device can provide multi-mode power supply plan according to different scenarios,and it can better achieve online power supply and other targets.
