| 摘 要： | 为了提高传统三相4线制电力系统谐波电流检测方法的精度,首先分析了传统的三相4线制中谐波电流检测存在的不足,并针对不足提出了基于瞬时无功功率理论的传统三相4线制谐波检测的两点改进方法,最后采用MATLAB仿真软件对改进方法进行了仿真,仿真波形显示,通过改进方法补偿后的三相电流获得了较好的改善.理论分析和仿真结果证明了这种改进方法的可行性和实时性.

| Abstract: | In order to improve the precision of the traditional method of harmonic current detection in three-phase-four-wire system,firstly analyzed the disadvantages of the traditional harmonic detection method in three-phase-four-wire system,and proposed two points to improve the harmonic detection method based on instantaneous reactive power theory,and simulates the new method with MATLAB software.The simulation waves demonstrate that the three phase currents after compensation have improved through the new method.The theory analysis and the simulation results with MATLAB demonstrate the feasibility and practicality of the improved method. |
