摘要
分析西门子SINAMICS变频器在电源电压变化和突降时的响应。从西门子SINAMICS系列电源电压的范围,允许的电压变化入手,研究了非调节型和调节型SINAMICS整流单元的运行特性,得出降低幅值大、持续时间长的电源电压骤降影响的措施,以及电源电压允许的谐波。
Analysis response of SIEMENS SINAMICS series converter in power supply voltage change and sudden drop. Starting from the range of Siemens SINAMICS series power supply voltage and the allowable voltage variati on, the operation characteristics of non-regulated and regulated SINAMICS rectifier units are studied. The measur es to reduce the impact of large amplitude and long duration of power supply voltage sags and the allowable harmo nics of power suppl y voltage are ob tained.
