由于对节约和环境保护的关注，以电力电子为基础的新型家用电器正在获得认可。这类器具的一个共同特点是它们都是谐波源。充分模拟这些电器的谐波产生特性对于评估它们对配电系统的集体谐波影响至关重要。提出了一种获取电力电子类家电谐波模型的方法。该方法是基于要建模的器具的测量而开发的。利用记录的电压和电流数据来估计谐波模型的参数。在紧凑型荧光灯和计算机负载下验证了该方法的准确性。
New power electronic-based home appliances are gaining acceptance because of concerns about conservation and environmental protection. A common characteristic of such appliances is that they are harmonic sources. The adequate modelling of these appliances' harmonic-producing characteristics is essential for assessing their collective harmonic impact on power distribution systems. A method to obtain harmonic models for power electronic-based home appliances is presented. The method is developed based on the measurements of the appliances to be modelled. The recorded data of voltages and currents are used to estimate the parameters of the harmonic model. The accuracy of the proposed method is verified for compact fluorescent lights and computer loads.
