本文提出一种基于Matlab的电能品质监测方法，能够较为准确地监测配电位置的电能品质，对电能的瞬态变化情况进行监测，为电力推进系统中电能变流方案提供有力的数据支持，并能精确地分析船舶电网工作状态，为船舶电网提供早期故障预警和后期故障诊断数据。本文所提出的方法通过系统化分析逐个采样点找出畸变数据，计算出总畸变率，并与用户要求的容差值进行比较，对不符合要求的电能参数予以预警。经过测试分析，软件能够在一定程度上完成电能品质监测任务。
This paper proposes a matLAB-based power quality monitoring method， which can accurately monitor the power quality of distribution position， monitor the transient changes of power， provide powerful data support for the power converter scheme in the electric propulsion system， and accurately analyze the working state of ship power grid. It provides early warning and late fault diagnosis data for ship power grid. The method proposed in the paper finds the distortion data one by one through systematic analysis of sampling points， calculates the total distortion rate， and compares it with the tolerance value required by users， so as to give early warning to the power parameters that do not meet the requirements. After testing and analysis， the software can complete the power quality monitoring task to a certain extent.
