| 摘 要： | 根据华东５００ｋＶ电网中几个具有代表性的变电站连续２４ｈ谐波测量数据，统计分析了谐波的变化趋势，归纳出谐波的基本特征，并从谐波源及５００ｋＶ电网结构分析了产生该谐波特征的基本原因。根据统计分析，进行了谐波仿真计算，其结果与实测统计结果基本一致。提出了降低华东５００ｋＶ电网谐波的基本措施。

| Abstract: | According to the 24 hour continuous harmonic measurement results in several representative substations of East China 500kV power network in 1997, the variation of harmonic voltage with time and harmonic character are given. The simulation calculation on harmonic level of East China 500kV power network is also performed. The calculation results are basically coincident with the measurement results. The reason why the harmonic voltage deviation factor is higher in 500kV power system is also analyzed based on harmonic source, transmission characteristic and harmonic impedance feature in 500kV power system. Finally, the measures to reduce the harmonic in 500kV East China power network are proposed. |
