摘要

电能质量反映了电力系统的适宜性。近年来,人们努力提高电能质量。采用多脉冲变换器实现高质量的电能输出。用移相变压器获得12和24脉冲作为输出。电能的质量主要取决于一些参数,如电压幅值的变化、电压/电流的瞬态、波形中的谐波含量等。因此,本文通过比较6、12和24脉冲的总谐波失真(THD)来表明电能质量的改善。在本文中,MATLAB的结果与硬件结果进行了验证。

THD comparison for power quality (MATLAB simulation & hardware)
Power quality shows the fitness of electrical power system. In recent years, efforts are made to upgrade power quality. Multi pulse converters are used to achieve good quality of electrical power. Phase shift transformer is used to obtain 12 and 24 pulses as outputs. The quality of power mainly depends on some parameters like, variation in voltage magnitude, transients in voltage/current, harmonic content in waveforms etc. So in this paper, improvement in power quality is shown by comparing the THD (total harmonic distortion) of 6, 12 & 24 pulses. In this paper, the results of MATLAB are verified with the hardware results.
