摘要

分别推导出谐波、三相不平衡和电压偏差扰动下新能源配电网附加损耗计算模型,通过仿真对这3种扰动下新能源配电网附加损耗进行量化分析。利用基波和谐波的三相不平衡度以及电压偏差推导出一种计及3种电能质量共同扰动下新能源配电网损耗计算模型,通过仿真和现场试验对所推导计算模型进行验证,对典型电能质量共同扰动下新能源配电网损耗进行量化分析。结果证明：在计及3种电能质量扰动下配网附加损耗计算模型误差与仿真和实验平台对比分别能保持在2%和3%以内;不同电能质量共同扰动下不同附加损耗之间存在耦合,不满足叠加定理。

Abstract

Calculation models for additional losses in new energy distribution networks under harmonic, three-phase unbalance, and voltage deviation disturbances are derived in turn. The additional losses in the new energy distribution network under these three transients are quantified and analyzed by simulation. A new energy distribution network loss calculation model under three power quality co-disturbances is derived by utilizing fundamental and harmonic three-phase unbalance and voltage deviation. The derived computational model is verified through simulation and field experiments. The new energy distribution network loss under typical power quality disturbances is analyzed quantitatively. The findings indicate that the error of in the additional loss calculation model of distribution network can be kept within 2% and 3% respectively compared with the simulation and experimental platform when considering three types of power quality disturbances. There is coupling between different additional losses under different power quality disturbances, which does not satisfy the superposition principle.
