在区域电网和省网中安装电能质量监测终端并结合专用的中心站软件可组成电能质量监测系统,实现大量历史数据的统计分析,形成各种统计报表,绘制谐波频谱图和各种指标的分布图,为电能质量的监督提供了先进的手段。结合电能质量分析的主要难点,举例说明了电力技术人员对电能质量监测数据的分析方法及其基本思路,提出了专业化的数据挖掘、系统性的电能质量分析是电能质量监测系统应用的焦点。
In the regional power grid and provincial network to install power quality monitoring terminal and a dedicated center station software can be composed of power quality monitoring system to achieve a large number of statistical analysis of historical data to form a variety of statistical reports to draw harmonic spectrograms and various indicators Distribution, for the supervision of power quality provides an advanced means. Combining with the main difficulties of power quality analysis, this paper gives an example of the analysis method and basic idea of power quality monitoring data for power technicians, and puts forward the specialized data mining. The systematic power quality analysis is the focus of application of power quality monitoring system.
