混合型有源滤波装置的应用研究

介绍了应用于煤矿的并联混合型6kV有源电力滤波装置的主电路和控制系统设计的原理。该装置是由有源滤波器、晶闸管投切的滤波器和固定补偿装置组成的混合型补偿装置。为了充分发挥各个功能单元的作用，该装置采用了基于瞬时无功理论的基频无功电流提取法和基于FIR数字滤波算法的谐波电流检测的分解合成控制方法。实践证明，上述方法不仅有效地抑制了直流传动矿井提升机所产生的谐波，同时实现了对其无功功率的连续补偿。成功运行的经验表明，混合型有源滤波器对于煤矿配电系统电能质量的控制效果良好。

Research and Application of Hybrid Active Power Filter

Principles of main circuit and control system design for a shunt hybrid APF with 6 kV are proposed for applying in a colliery.This device is a hybrid compensator consisting of APF,TSF and FC.In order to put each device into full play,the decomposing and composing control method for the fundamental frequency reactive current instruction based on the instantaneous reactive power theory and the harmonic current inspection with the FIR digital filter algorithm is applied.The practice proves that the proposed co...
