摘要
由于交-交变频主传动在运行过程中将产生与输入频率及相数相关的特征谐波以及与输出频率及相数相关的旁频谐波等高次谐波和电压波动;为了解决上述问题并考虑到工程投入的问题,设计了STATCOM+FC补偿方案,采用基于DSP的全数字化控制器,控制器响应时间≤10 ms,系统响应时间≤20 ms;能使系统平均功率因数达到0.95以上,谐波电流和电压波动优于国标允许值。
The input frequency and phase related characteristic harmonics as well as the output frequency,phase related adjacent higher harmonics and voltage fluctuations are generated during the operation of AC-AC variable frequency main drive.To address these issues and taking into account the engineering input,a STATCOM ＋ FC compensation project is designed.The digital controller was based on DSP while the controller response time ≤ 10ms,system response time ≤ 20 ms,which enable the system average power factor above 0.95 and the harmonic current and voltage fluctuations better than that of national standards allowed.
