Resonance Analysis and Countermeasure Research of 10 kV Shunt Capacitor
Aiming at a recent harmonic amplification event in a power supply bureau of Yunnan Power Grid,the measured harmonic data before and after capacitor switching were compared and analyzed to veri-fy that this is a phenomenon of harmonic current amplification caused by harmonic resonance with the sys-tem after the shunt capacitor is connected,and then the mechanism of harmonic current amplification by shunt capacitor was revealed through simulation modeling.Finally,based on the theory of harmonic reso-nance,the suppression measures for harmonic resonance of 10 kV shunt capacitors were proposed.
