Automatic Monitoring Model for Power Quality of Small Hydropower Grid Based on Entropy Weight Method

常见的小水电上网电能质量监测模型在扰动环境下,模型的抗攻击性能较差。基于此,提出基于熵权法的小水电上网电能质量自动化监测模型。针对自动化监测需要,搭建远程通信模块,实现自动化远程监测功能,在此基础上,采集电能质量监测数据,约束电能质量各类型信息属性,将采集到的监测信息作为电能质量评价指标,利用熵权法计算电能质量综合评价指数,监测电能质量变化情况。实验结果表明:在扰动环境下,设计的基于熵权法电能质量自动化监测模型负载水平高,电压损耗低于0.2,其整体抗攻击特性得到提升。

The common small hydropower grid power quality monitoring model has poor anti attack in disturbed environment.Based on this,an automatic monitoring model of power quality of small hydropower grid based on entropy weight method is proposed in this paper.According to the needs of automatic monitoring,it builds a remote communication module to realize the automatic remote monitoring function.On this basis,it collects the power quality monitoring data,restricts the various types of information attributes of power quality,takes the collected monitoring information as the power quality evaluation index,calculates the comprehensive evaluation index of power quality by using the entropy weight method,and monitors the changes of power quality.The experimental results show that in the disturbed environment,the designed automatic power quality monitoring model based on entropy weight method has high load level,voltage loss is less than 0.2,and its overall anti attack characteristics are improved.
