摘　　要：煤矿电力系统中除特征谐波外还含有许多非特征谐波,这些谐波会使系统性能变差,甚至导致系统发生谐振而毁坏,而传统的无源滤波器无法滤除。针对这些问题,提出了一种新型并联混合型有源电力滤波器(parallel hybrid active power filter,PHAPF),并分析了其工作原理,在复合控制策略下可将负载谐波电流与电网侧谐波电流同时检测,由于网侧电流闭环系统不承担补偿谐波电流的主要任务,因此系统的等效电阻值不需要太大。搭建MATLAB仿真模型,仿真结果表明复合控制策略下具有良好的滤波效果和工程应用前景。Besides characteristic harmonics, there are many non-characteristic harmonics in power system. The common passive filter cannot deal with it, which worsens performance and may be results in the resonance to destroyed the filter device. Aiming at these problems, a new type of parallel hybrid active power filter (PHAPF) is proposed, and its working principle is analyzed. Under the combined control strategy, the load harmonic current can be detected simultaneously with the grid side harmonic current. The side current closed-loop system does not undertake the main task of compensating the harmonic current, so the equivalent resistance value of the system does not need to be too large. The MATLAB simulation model is built. The simulation results show that the composite control strategy has good filtering effect and engineering application prospects.
