A Study on the Harmonic Norton Model of Residents Singlephase Nonlinear Loads

摘    要
谐波诺顿模型是一种非线性负荷模型,使用可编程交流电源构造不同电压类型(平坦波和尖顶波),且电压畸变率为5%获得PCC处电压和电流的波动量(两种不同运行状态下得到的谐波电压和谐波电流)。结果表明:居民单相非线性负荷诺顿模型参数不是恒定的,不同构造电压下获得的参数变化较大,且模型只在相同电压类型(平坦波或尖顶波)下才稳定些,大量实验及测试数据计算结果验证了这一结论。实验还表明:低压配电系统的电压波形是平坦波,这为构造居民单相非线性负荷诺顿模型提供了有利条件。

Abstract
Harmonic Norton model is a harmonic model for residents of nonlinear load. The study is conducted with a programmable AC power supply to apply various voltage waveshapes with 5% THDv getting the PCC voltage and current fluctuation(using harmonic voltage and current differences between two operation conditions), The test results show that the Norton equivalent model for residents of nonlinear load is not unique and varies significantly with applied voltage waveshape. Additionally, the field test results show that the distribution voltage waveform always presents the flatten peak shape. It provides good circumstances for the harmonic Norton model construction and utilization for residents singlephase nonlinear loads in distribution systems.
