Abstract
With the consideration that the location method for harmonic sources(HSs)based on harmonic state estima-tion(HSE)requires more harmonic meters,a two-stage location method for HSs is proposed in this paper.Firstly,an im-proved independent component analysis(IICA)algorithm considering measurement error is applied to initially select HSs.Then,on the basis of selection results and with the combination of the impact of measurement error and parame-ter error on HSE,total least squares(TLS)algorithm is used to estimate the harmonic injection current on suspicious nodes,thereby realizing the location of HSs accurately.Finally,the validity of the proposed method is verified by simu-lations conducted in an IEEE 14-node system with the evaluation indices of failure rate,mean value of root mean square error,and the minimum number of harmonic meters.关键词
