A Novel Method to Harmonic Sources Placement

Abstract: This paper proposes on a new method for measurement placement of power system harmonic state estimation. Due to limitation in number of installed harmonic measurements, harmonic state estimation has been considered as one of the famous methods for measuring voltage and injection current of busbars and lines current and placement of these measurements with algorithm based on sequential elimination method. Also, after the algorithm find location of measurements in harmonical busbars, by minimization number of sites technique that collect harmonic data from measurement devices, optimal placement of these measurements will be done. This technique can find optimal place of measurement for identification location and intensity of harmonic sources. The proposed method have been performed on IEEE 14-bus with 69 possible locations to install these measurement in Matlab software. The simulation results depicts that the proposed system works correctly
