摘　　要：晶闸管投切电容器(TSC)由于控制简单,成本低廉,在实际中得到了广泛的应用。本文介绍了基于dsPIC30F6014的数据采集系统和S3044BOX的主控系统构成的无功补偿控制器的工作原理,并提出了采用DMA的方式实现上位机和下位机的通讯,提高了CPU的利用率。结果表明,本无功补偿控制器具有良好的补偿效果。Thyristor Switched Capacitor （TSC） because of simple control and low cost had a wide range of applications in practice. This paper introduces the working principle of the reactive power compensation controller which constituted by the dsPIC30F6014- based data acquisition system and S3C44BOX-based main control system. And proposed DMA ways to achieve the communication between the upper and lower machine.Improved the utilization of CPU. The result shows that this reactive power compensation controller had a good effect.
