管道压缩机的电驱系统以电压源型变频器驱动无刷励磁同步电机,采用同步启动控制方式能够解决无位置传感器启动困难的问题,但可能产生启动时电机短时反转情况。通过分析变频器常用的无刷励磁同步电机启动控制方案,以16 MW压缩机组电驱系统调试过程为案例,引入无位置传感器同步电机低频脉冲注入控制方案,经过现场测试验证了改进方案的有效性,成功地解决了同步电机的启动反转问题,保证了压缩机组启动安全和稳定运行。低频脉冲注入控制方案首次成功应用于无刷励磁同步电机启动反转抑制,对今后变频器控制系统持续改进有示范和指导意义。
The power drive system of the pipeline compressor drives the brushless excitation synchronous motor with a voltage source converter. The synchronous starting control scheme can solve the problem of difficult starting without position sensor, but it may cause a short time inversion of motor rotation during starting. By analyzing the starting control scheme of brushless excitation synchronous motor commonly used in frequency converter, using commissioning process of a 16 MW electric motor driven system as an example, this paper introduces a Low-Frequency Pulse Signal Injection (LF PULSE) control scheme for sensorless brushless synchronous motor. The field test verifies the effectiveness of the improved control scheme in solving the issue of rotation inversion during starting and ensures the safe start-up and stable operation of the unit. The Low-frequency Pulse Signal Injection is successfully applied for the first time to suppress rotation inversion during starting of the brushless excitation synchronous motor, which has a significance in demonstrating and guiding the continuous improvement of the converter control scheme in the future.
