摘要
分析世博会庆典广场喷泉变配电所负荷特征,探讨大容量、突变性非线性设备的谐波抑制和治理方案。依据该类型负荷谐波测试统计数据,估算谐波电流,设计选用有源电力滤波器,并对比分析有源电力滤波器投入前后的谐波数据。
The load characteristics of the distribution substation for fountain on the Celebration Plaza during Shanghai World Expo are analyzed, and the harmonic suppression and treatment scheme for mutational nonlinear equipment with large capacity are discussed. Based on the statistical data of harmonic test of such load, the harmonic current is estimated, the active power filter is designed and selected, and the harmonic data before and after the application of the active power filter are analyzed by comparison.
