摘要
分布式储能装置在负荷低谷时作为负荷从电网获取电能,在负荷峰值时向电网提供电能,并能补偿负荷无功功率,提高供电可靠性和电能质量。该装置以蓄电池为储能媒介,采用TMS3202812型DSP控制智能功率模块(IPM),将充电电路和逆变电路合二为一,实现AC/DC和DC/AC的电能转换,并可以运行在低压静止无功发生器的方式,为负荷提供无功电流。介绍了分布式储能装置的基本构成、控制电路的结构和整流/逆变电路的构成,给出了系统程序设计思路和变流器电压、电流瞬时值的双环控制方法,并结合样机试验结果分析了装置实际应用的可行性。
The distribute energy storage device uses storage battery, and adopts digital signal processor (DSP) and the intellectual power module (IPM) as the two-direction converter to realize AC/DC or DC/AC transfer.It combines charging and discharging circuit into a single unit and offers var compensation electric current to load by way of working on lowvoltage static var compensation generator.This paper introduces the construction of distributed energy storage (DES), control circuit and rectifying/inverting circuit, provides the system program design and voltage/current double-loop control about inverter.The application probability is analyzed based on the prototype test results.
