基于DIgSILENT/PowerFactory的多谐波源电网谐波评估

摘要

介绍了一种应用电力系统仿真软件DIgSILENT/PowerFactory进行电力系统谐波水平评估的方法。利用软件确定电网中各元件的谐波模型及参数，结合谐波源实测数据确定谐波源模型，建立系统谐波潮流计算仿真模型。在此基础上，以云南电网黄坪片区电网数据为基础搭建仿真实例，通过电网谐波潮流计算对该片区未来谐波水平进行评估。%In this paper, a method of assessing power system harmonics with simulation software DIgSILENT/PowerFactory is introduced, in which the harmonic model and parameters of each ele-ment of the grid are determined. The model of harmonic sources is created based on the actually measured data of the harmonic sources. The simulation model is set up based on grid data of Huang-ping area of Yunnan grid and future harmonic level of the rear in the future is assessed throughout harmonic flow calculation of power grid.
