注入式有源谐波电阻谐振抑制方法
Harmonic Resonance Suppression Method Based on Injected Active Harmonic Resistance
摘要
Abstract
Nowadays, the voltage level of microgrid is developing towards medium-level progressively. To compen-sate 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 distri-bution 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 har-monic 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 nor-mal operation of the system effectively.关键词
