摘要
The present invention discloses a harmonic analysis and maintenance method for grid interconnection of a double-powered wind power generator set, and is based on a mathematical model of a double-powered wind power generator set. Build an electromagnetic transient model of the machine set, perform electromagnetic transient simulation calculations on the wind farm using the ADPSS simulation system, obtain the harmonic current and harmonic voltage injected from the wind farm into the power grid, and wind. The harmonic current injected from the farm into the power grid is compared with the harmonic current threshold, the harmonic voltage injected from the wind farm into the power grid is compared with the harmonic voltage threshold, and the wind farm is injected into the power grid. Determine if the harmonic current or voltage to be applied exceeds the standard, and if the harmonic current injected from the wind farm into the grid exceeds the standard, design an active filter and wind the wind including the active filter. Build a farm electromagnetic transient model and correct harmonic currents in the grid.
