| description | The core module of renewable energy power generation system is grid connected inverter. LCL-based grid-connected inverter is widely valued because of its superior high frequency harmonic suppression ability. LCL-filter has better high frequency harmonic attenuation and better filtering effect, but resonance suppression should be considered. In this dissertation, the inherent damping characteristic of LCL-filters is used to improve the resonance suppression. Two-mass drive system has the problem of torsional vibration when the torsion changes instantaneously. This issue can be solved using the same method as the LCL-filters. Both systems are modeled and simulated in PLECS to find the effect of resonance suppression or torsional vibration suppression. The two systems will be compared with each other. |
