摘要：为了对磁阀式可控电抗器(MCR)进行有效的控制和监测，以DSP和ARM数字处理器为核心，设计了MCR的控制系统。系统采样负载电压、电流，由dq算法得到需要补偿的无功功率，再由DSP控制算法输出对应晶闸管导通角的触发脉冲，进而调节MCR无功补偿量。基于ARM系统建立了界面友好的人机界面系统，供用户设置系统运行参数，查看系统运行数据，保存和查询故障记录。实验结果表明该系统可靠、实用。

Abstract: In order to effectively accomplish control and detection of magnetic-valve controllable reactor(MCR), a control system with digital signal processing(DSP) and ARM as the core was designed. Load current and voltage was sampled, and the reactive power for compensation was gotten, and through dq algorithm thyristor trigger pulse which adjusted MCR reactive power output was generated by DSP. Human-machine interface system for users was established based on ARM to set the system operating parameters, view the system operating datas, record and access failures. Experimental results show that the system is reliable and practical.
