摘　　要：现代煤矿电网中大容量电力电子装置广泛应用,其非线性负载特性导致谐波污染越发难以治理。级联多电平有源电力滤波器能够在大容量、高电压的环境中进行谐波补偿,因此采用一种改进的dq坐标系下的谐波检测方法,对煤矿电网电能质量进行有效调节。仿真结果表明:有源电力滤波器动态响应几乎瞬间完成,补偿器工作仅0.05 s,畸变电网电流已经正弦化。Large-capacity power electronics widely used in modern coal mine power grids,and their nonlinear load characteristics make harmonic pollution more and more difficult to manage.Cascaded multilevel active power filters are capable of harmonic compensation in high-capacity high-voltage environments.An improved harmonic detection method in dq coordinate system was used to effectively regulate the power quality of coal mine power grid.The simulation results show that the dynamic response of the active power filter is almost instantaneous,the compensator works only for 0.05 s,and the distorted grid current has been sinusoidal.
