供电质量自动检测系统的设计

System Design of Power Supply Quality Automatic Detection

文章主要阐述了电能质量参数的自动检测问题。提出了通过单片机测量脉宽的频率测量方法和一种与接线无关的三相功率测量功率因数的方法。并针对具有广泛影响的电能质量问题提出了检测电力参数的几种方法,并且对未来电能质量自动检测系统的设计提出了见解。

This thesis expatiated the automatic detection of a few parameters on power quality. A single-chip is used to measure the impulse width and the frequency to fix the power factor, a method using three-phase power, which has nothing to do with connection, was applied. Aiming at the power quality, which has extensive influence, some methods of testing these parameters are shown, hut also put forward some related viewpoints concerning the future development of automatic test system.
