摘要
传统储能变流器的设计是适配固定的三线或者四线电网线制,无法根据实际应用情况自动进行线制的调整,在使用时存在一定的局限性。为适应更多的应用场景,基于储能变流器设计原理,根据储能电池pack的配置构成,结合单体电池和电池组的充放电区间范围,以及不同的电网电压,研究了一种电网线制自适应的储能变流器,可以根据直流侧的电池电压,自动调整储能变流器的交流线制,适配系统的应用,并给出了具体的设计原理和方法、模块构成及控制策略,最后通过储能变流器测试平台测试及实验,验证了设计的可行性和有效性。
The traditional design of energy storage converter is adapted to fixed three-phase or four-phase grid wiring sys⁃tems,and cannot automatically adjust the wiring system according to the actual application conditions.There are certain limitations when in use,to adapt to more application scenarios,based on the design principle of energy storage con⁃verter,according to the configuration of the energy storage battery pack,combined with the charging and discharging range of individual batteries and battery groups,as well as different grid voltages,a grid wiring system adaptive energy storage converter has been studied.It can automatically adjust the AC wiring system of the energy storage converter according to the battery voltage on the DC side,adapt to the application of the system,and the specific design principle and method,module composition and control strategy are given.Finally,through the test platform and experiments of the energy storage converter,the feasibility and effectiveness of the design have been verified.
