针对煤矿井下电网谐波污染严重的问题,提出了一种确定井下电网有源电力滤波器接入位置和容量的计算方法,该方法不仅可以抑制煤矿井下电网的谐波污染,还可以有效的降低谐波治理的投资成本。在该方法中,建立了基于瞬时无功功率的离散化APF时域模型以及基于固定成本和容量成本的优化模型,使用了粒子群优化算法对优化模型进行了求解,保证了所得最优解更加符合工程实际。通过仿真对有源电力滤波器接入位置和容量的计算方法进行了验证,结果证明了其正确性。

A calculation method for the allocation and sizing of active power filters (Active Power Filter,APF) in un- derground power system is proposed in this paper,considering the severe harmonic pollutions of the underground coal mine power system. The method suppresses the harmonic pollutions of the underground coal mine power system and al- so minimizes the investment cost largely. A discrete APF time domain model based on instantaneous power theory and an optimization model based on both fixed cost and unit cost are established. A particle swarm optimization is employed to solve the optimization problem. The method presented ensures that the optimal solution is practical. Based on the simulations results,the correctness of the method for the allocation and sizing of active power filters is verified.
