Abstract:
      Nowadays, the voltage level of microgrid is developing towards medium-level progressively. To compensate the transmission of a large quantity of reactive power, reactive compensation capacitors are usually installed in medium-voltage distribution networks, which will amplify the harmonic current in the grid and even endanger the distribution network in the case of serious resonance problems. In this paper, harmonic resonance modal analysis method is used to analyze the harmonics in a medium-voltage distribution network at first. Then, based on the injected active harmonic resistance(AHR), a impedance model of AHR in voltage-controlled-current mode is set up, and its effect on the har-monic resonance damp is analyzed. Simulation and experimental results proved that the proposed harmonic resonance analysis and suppression method can predict and damp the harmonic resonance obviously, which can guarantee the normal operation of the system effectively.
