摘　　要：针对煤矿供电网需要实时动态地补偿电网中瞬态变化的谐波电流,提出一种基于空间电压矢量脉宽调制技术的控制策略;设计了一种适用于煤矿供电网的并联混合有源电力滤波器(PHAPF)的拓扑结构,并对拓扑结构的控制策略进行了研究,控制策略直接影响到有源电力滤波器的滤波性能。混合有源电力滤波器的有源电力滤波器经过三相耦合变压器,串接LC串联谐振无源滤波器,降低有源滤波器的容量和承受的基波电压。通过理论分析和Matlab仿真,验证了混合有源电力滤波器的控制策略能够提高煤矿供电网的电能质量。Because the power grid of coal mine requires that harmonic current needs real-time transient compensation, proposes a control strategy based on SVPWM and designs a topological structure of a parallel hybrid active power filter （PHAPF） for coal mine power grid. Then the control strategy of topological structure is being discussed. The control strategy directly influences the filter performance of active power filter. The active power filter connects with LC series passive power filter via three-phase coupling transformers. This can reduce active filter capacity and fundamental wave. Through theoretical analysis and Matlab simulation, the control strategy of a parallel hybrid active power filter can improve the power quality of power grid for coal mine.
