摘要
钢厂电弧炉等冲击性负荷接入电网,会引起电网电压波动与闪变、三相不平衡、电压电流波形畸变等电能质量问题。研究设计了一种基于DSP的滤波电容器+晶闸管相控电抗器(FC+TCR)型动态无功补偿装置。装置依据Steinmetz三相不平衡负荷的补偿原理,采用先进的DSP芯片TMS320F2812作为控制器的核心,保证了系统的实时响应速度和控制精度。试验显示,该装置能有效抑制电网电压的波动与闪变,改善系统三相不平衡度。
Connecting the Fluctuant loads such as electric arc furnaces into electric networks shall causes the fluctuation and flicker of voltage, the imbalance of three phase power supply and some other problems of electric quality. Based on Steinmetz compensation theory,this paper introduces a sort of dynamic reactive power compensator of the type of Filter Capacity adding Thyristor Controlled Reactor（FC＋TCR）. The device adopts advanced DSP chip TMS320F2812 as the core of the controller,which ensure its real time response speed and control precision.The testing showed that this device can eliminate the fluctuation and flicker of voltages and improve three phase imbalance state effectively.
