大型光伏电站与电网谐波交互影响
Harmonic Interaction Between Large-scale Photovoltaic Power Stations and Grid
摘要
Abstract
Grid-connected photovoltaic (PV) power station of large scale may lead to high frequency and wide-band frequency of power system harmonics. The effects caused by distributed capacitance of transmission line which used to be neglected on these harmonics turns to be prominent. Output characteristics of high and low harmonics in PV station were given at first. Mathematic model in fundamental domain of PV station and grid was established. On the basis, series-parallel resonant mathematic model of harmonic was proposed and mechanism was discussed. Meanwhile, relationships among harmonic amplification factor and transmission distance, harmonic order as well as type were analyzed. The simulation model of large-scale PV station was given according to the local PV station in Qinghai province, and real data was measured. The proposed scheme was verified by contrast of simulation data and real data.关键词
