The imitation of using harmonic measurements which must be installed in the network, harmonic state estimation has been considered as one of the famous mehtods for measuring voltage and injaction current busbar, line current and placing these measurements with algorihm based on sequential elimination mehtod. 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 measurment devlces optimal placement of these measurement will be done. tapping into this technique, opitmal placement of measurements to identify the location and internsity of harmonic sources cab be found. this investigation have been implemnted on IEEE 14-bus with 69 possible location to install these measurment in matlab software.
