| 摘 要： | 提出一种动态无功补偿结合有源滤波的综合控制方法,该方法通过统一的检测和控制算法,分别控制晶闸管投切电容器(Thyristor Switched Capacitor,简称TSC)进行无功功率动态粗补偿,脉宽调制的并联有源滤波器(APF)进行动态滤波和无功功率动态细补偿,从而大幅度降低有源滤波器的容量,减少装置产生的谐波,避免因参数谐振对系统产牛的不利影响,降低设备的功率消耗.通过Matlab数字仿真验证了该方法的正确性和可行性.该控制方法对非线性冲击负荷较大的工业企业和电网实现节能降耗、改善电压质量及提高供、用电设备效率具有重要作用.

| Abstract: | A kind of integrated control method for dynamic reactive power compensation and active filtering is presented.Through the unified detection and control algorithms,the thyristor switched capacitor(TSC) is used for rough dynamic reactive power compensation and active power filter(APF) is used for dynamic filtering and reactive power compensation.This method can greatly reduce the capacity of the active filter,the power consumption of the epuipment and the harmonics caused by non-linear load,and also can avoid... |
