以提高电能质量管理水平为目的,根据实际工作中的具体需求,针对利用海量电能质量监测数据实施高级分析应用的难点问题,基于江西省电气化铁路电能质量监测系统,提出采用模糊综合评估法对监测点综合电能质量水平进行量化评估,采用基于二元线性回归的谐波源辨识方法,以贡献率指标进行谐波源判断,通过测算电压跌落时刻量测点的电压、电流及电压电流之间的夹角来进行跌落源辨识。应用结果表明,所提出的分析方法比较适合于现
In order to improve the level of power quality management, according to the specific requirements in practical work, aiming at the difficult problems of using advanced power quality monitoring data to implement advanced analysis and application, based on the Jiangxi Provincial Electrified Railway Power Quality Monitoring System, this paper proposes a fuzzy comprehensive evaluation method to monitor Point comprehensive power quality level quantitative assessment, the use of binary linear regression based on the harmonic source identification method to determine the contribution rate of the harmonic source to determine, by measuring the voltage drop at the measuring point voltage, current and voltage and current between Angle to fall source identification. The application results show that the proposed analysis method is more suitable for now
