    Abstract 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.
