Application and Exploration of Power Radar in Harmonic Traceability

为实现对多谐波源系统的谐波责任正确判别,提出一种基于电力雷达的谐波溯源方法。首先基于电力雷达超高精度的时间测量功能,依据IEEE 1588网络时钟同步技术对各谐波源处的电力雷达进行同步精确对时,在时域上根据同一时刻检测到产生谐波的各谐波源与公共连接点处的谐波响应的对应关系实现各谐波源定位,再根据电力雷达的录波功能量化各个谐波源的谐波贡献度,最终形成一种基于电力雷达的谐波溯源方法。理论分析了该方法在电力谐波溯源中的可行性,为电力雷达的市场化应用方向提供了一定的参考价值。

To realize the correct discrimination of harmonic responsibility of the system,a harmonic traceability source method based on power radar was proposed.Firstly,based on the ultra-precision time measurement function of the power radar,IEEE 1588 network clock synchronization technology was used to realize the accurate time synchronization of power radar at each harmonic source.Besides,in the time domain,according to the corresponding between the harmonic sources that detect harmonics at the same time and the harmonic response at the common connection point,the location of the harmonic source was achieved.Then,the harmonic contribution of each harmonic source was quantified according to the waveform recording function of power radar,and a method of harmonic traceability based on power radar was formed.The feasibility of this method in power harmonic traceability was analyzed theoretically,which provided a certain reference value for the market application of power radar.
