摘要
有源电力滤波器是解决电能质量问题的关键设备,而检测技术是其可靠运行的重要保障。该文首先研究任意三相系统谐波规律,然后基于dq0变换,针对电网电压波动、不对称、畸变等情况,提出一种适用于任意三相系统的不对称、谐波及无功电流的综合检测方法,并用严格的数学推导证明该检测方法,最后通过仿真验证该检测方法的有效性和正确性。
Active power filter is the significant equipment to solve power quality problems. Its reliable operation is safeguarded by the detection technique. Firstly, the harmonic law is studied in this paper. Then considering the voltage fluctuation, asymmetry, distortion and so on at power grid, a new method is proposed and proven strictly in a mathematical manner for the detection of unsymmetrical, harmonic and reactive currents in arbitrary three-phase systems based on dq0 formatting. Finally, the validity and correctness of the method are verified by simulation.
