某钢厂冷轧硅钢连退线传动系统采用西门子Simovert Masterdrives矢量控制交-直-交变频调速系统。在实际的生产运行中,该变频传动控制系统总是异常损坏。对此,首先从理论分析的角度了解该传动系统交流侧注入电网的谐波特点及其对该变频传动系统的影响;然后在Matlab Simulink中对该传动系统建模,并对系统负载交流侧谐波电流进行仿真分析,验证理论分析的结论;最后,对该传动系统的电能质量进行了现场测试,清楚地看到谐波治理方案设计的正确性。
A steel mill with cold-rolled silicon steel even line drive system using Siemens Simovert Masterdrives vector control AC - DC - AC frequency control system. In the actual production operation, the variable frequency drive control system is always abnormal damage. In this regard, we first understand the harmonic characteristics of the transmission system AC side injected into the power grid and its impact on the variable frequency drive system from the theoretical analysis point of view. Then, we model the drive system in Matlab Simulink, Wave current simulation analysis to verify the theoretical analysis of the conclusions; Finally, the power quality of the transmission system on-site testing, clearly see the design of harmonic control program is correct.
