OPTIMAL PLACEMENT OF MEASUREMENT DEVICES TO DETECT THE LOCATION AND INTENSITY OF HARMONIC SOURCES

The limitation of using harmonic measurements which must be installed in the network, harmonic state estimation has been considered as one of the famous methods for measuring voltage and injection current busbar, line current and placing these measurements with algorithm based on sequential elimination method.when the algorithm could find the location of measurements in various busbars at different harmonics, minimizing the number of sites technique in which they collect harmonic data from measurement devices, optimal placement of these measurement will be done. Tapping into this technique, optimal placement of measurements to identify the location and intensity of harmonic sources can be found.This investigation have been implemented on IEEE 14-bus with 69 possible location to install these measurement in Matlab software
