Methods of Harmonic Source Identification and Detection in Distribution Network

摘要

In order to create Green Grid and supply the electricity consumers with safe, liable and clean power energy, the accurate and practical harmonic source location methods are urgently needed. Therefore this paper concludes various harmonic source location methods based on the direction of power flow, and explains the disadvantages and advantages of the methods. At last, this paper studies the principles and realization of i_p - i_q algorithm. Moreover, in the Matlab/ Simulink, the model is established to stimulate. This paper further analyzes the principles and characteristics of i_p - i_q algorithm.
