电力用户低压谐波在线监测系统的研制

随着社会发展,用电设备中的电力电子元件的使用越来越多,致使大量的谐波电流注入电网,大量的谐波电压不仅影响电网安全运行,同时也影响电力用户的用电安全。从供、用电部门角度,分析了目前电力网中的谐波情况,研制了电力用户低压谐波在线监测系统,对低压谐波进行实时监测,当超出国家标准值时,便于电力用户采取有效的消谐措施,提升电网电能质量。该在线监测系统运行效果良好。

Development of Low Voltage Harmonic Online Monitoring System

With the development of society, the power electronic components used in electric equipment are more and more. This caused a large number of harmonic inject into the grid, so as that tile harnormic w）ltage influnences the safety running of grid and power users. From the perspective of power supply department, the harmonic situation in power grid was analyzed, low voltage harmonic online monitoring system was developed to monitor low voltage harmonic in real-time. When the harmonic value beyond the standard value, it is easy to the power user take effective measures. The low voltage harmonic online monitoring system running effect is perfect.
