摘要
文章分析了电力系统谐波对电网损耗、电能质量、供电效率等性能的影响。结合某变电站110kVII母电压异常波动,发现某用户10 kV电压表异常,接着对该用户进行数据采集,将采集的数据分析与比对,发现该用户向电网注入谐波,建议该用户进行治理。既避免电网事故的发生,又降低用户的成本。
This paper analyses the influence of power system harmonics on the power loss, power quality, power supply efficiency and other properties. Combining a substation 110kVII mother of voltage fluctuation, found that a user lOkV voltmeter is abnormal, then to collect the data of the user, the data analysis and corn- parison of collection, found that the user injects harmonic to the power grid, grid to prevent accidents, but also reduce the user cost. user management. The power
