摘要
本文中作者分析了光伏电站谐波电流和光伏系统出力特点及其对变压器损耗的影响,建立了数学模型,并通过仿真验证了该评估方法的合理性。
The characteristics of harmonic current and output of photovoltaic system and their influence on transformer loss are analyzed by the authors in this paper. The mathematical model is established and the rationality of the evaluation method is verified by simulation.
