一种基于谐波阻抗值的谐波源定位算法
A Kind of Harmonic Source Positioning Algorithm Based on Harmonic Resistance Value
摘要
Abstract
For defining harmonic pollution duties,this paper proposes a kind of harmonic source positioning method based on harmonic resistance value.Taking definition of IEC 61000-3-6 harmonic emission level as basis,it estimates harmonic resist-ance at the side of system and calculates harmonic voltage emission level of the customer.No matter whether the three-phase voltage and current are symmetrical or not,it proves that this method is applicable.At last,by some 1 1 0 kV non-linear cus-tom system testing data,it verifies correction of this method and by establishing physical simulation circuit in laboratory,it verifies feasibility of harmonic source positioning algorithm.Simulation result indicates that this algorithm is able to realize precise harmonic source positioning,distinguish source of disturbance and definitely divide harmonic pollution duties.关键词
